Disclosure up front: I’m an affiliate for Momentum, one of the two products in this comparison. If you buy through a link here, I earn a commission. I’m telling you now, not in the footnotes, because a comparison written by someone with a stake is only useful if you know about the stake. So I’m going to be hard on Momentum where it deserves it and fair to IM8 where it earns it — that’s the only version of this worth reading.

Here’s the bottom line, since you’re comparing and you want the verdict:

Both are good all-in-one shakes. IM8 is the broader, pricier, celebrity-backed one — about $183 a month for the full Beckham Stack. Momentum covers the same core ground — protein, collagen, NAD+ — for about $150 a month, and lets you trial a single bag first. Choose IM8 if you want the widest ingredient list and NSF Certified for Sport. Choose Momentum if you want most of the same job without paying for a David Beckham co-founder. The honest gap between them is smaller than the price difference makes it sound — and that’s the whole story.

Let me show my work.

What you’re actually paying for with IM8

IM8 is David Beckham’s shake. That’s not a knock — it’s the product’s headline, and it’s central to understanding the price.

The pitch is strong: “One sachet. 90 ingredients. Everything your body actually needs.” Co-founded by Beckham, endorsed by Giannis Antetokounmpo and Aryna Sabalenka, with Jay Shetty in the mix. It’s NSF Certified for Sport, which is a real, meaningful certification if you’re a competitive or drug-tested athlete. The review base is enormous — north of 16,000 — and the self-reported outcome stats are loud (around 95% felt more energy, 80% reported better sleep).

The cost takes a little unpacking, because IM8 sells a few tiers:

• Daily Ultimate Essentials (the single all-in-one drink) is marketed at roughly $6 a day — about $180 a month — and pitched as replacing “$4,000+/year in supplements.”
• The full Beckham Stack (Essentials Pro + Longevity) bills around $548 every 12 weeks, which works out to about $183 a month.

So when I say “$183,” I mean IM8’s full flagship stack — the apples-to-apples all-in-one comparison. Their cheapest single product is less, but it’s also doing less.

Here’s what I’ll give them without hesitation: ~90 ingredients is genuine breadth. If your goal is the single widest net, IM8 casts it wide. And the NSF for Sport cert is not nothing — for a tested athlete, that alone can be the deciding factor.

What you’re also paying for is a marketing machine. A global icon co-founder. Three more famous faces. That budget comes from somewhere, and it comes from the price.

What Momentum gives you for less

Momentum doesn’t have a Beckham. It has, in order of what actually matters:

• Grass-fed whey isolate — about 30g of protein. Real protein, not a token gram.
• Grass-fed collagen — joints, skin, connective tissue; the stuff you make less of past 35.
• An NAD+ precursor — the actual longevity ingredient. NAD+ is what your cells use for energy and repair, and it declines with age.
• Hyaluronic acid, digestive enzymes, a probiotic co-culture, electrolytes, and vitamins D and K2 — the supporting cast.

It’s third-party tested and HSA/FSA eligible. The pitch — “two scoops replace 20+ separate supplements” — is the same stack-replacement promise IM8 makes, just without the 90-ingredient arms race. Momentum doesn’t try to win on ingredient count. It leads with named longevity actives, dosed where you can see them.

I’ve taken it daily for four months. If you want the unabridged version — taste, what I noticed week by week, what I’m taking on faith — that’s in my full Momentum longevity shake review. For this page, the relevant point is: it does the core job IM8 does.

The price reality (let me be straight about the numbers)

This is where most comparisons get lazy or sneaky, so I want to be precise.

You’ll see $75–80 on the Momentum site and might think that’s the monthly price. It isn’t. That’s the price of one bag ($80 one-time, $75 on subscription), and a bag is two scoops a day for about two weeks. A full month is two bags — about $150 on subscription. I’d rather tell you that plainly than let you anchor on $80 and feel misled at reorder. (If you want to never get that wrong, I made a 90-second first-order cheat sheet that covers it.)

So the real, honest comparison is $150 a month vs. $183 a month. Not “half price” — anyone telling you that is fudging the per-bag number. It’s about $33 a month less, or roughly a dollar a day.

Is a dollar a day a big deal on its own? No. What makes it matter is what the extra dollar buys. When I look hard at IM8 versus Momentum, the core ingredients you’d actually feel — protein, collagen, NAD+ support — are present in both. The extra $33 a month is buying you ingredient breadth (the back half of those ~90 ingredients, many at modest doses) and a marketing budget with a footballer on it. If breadth and the brand matter to you, that’s a fair trade. If they don’t, you’re paying about $400 a year for a name.

There’s also the trial math. With Momentum you can buy a single $75–80 bag, run it for two weeks, and bail if you hate it. IM8’s full stack is a heavier upfront commitment for the same “let me see if I like this” question. For a skeptical buyer, that lower bar to entry is worth something.

The celebrity-markup question

Let me ask the question the SERP is full of — “why is IM8 so expensive?” — and answer it fairly.

It’s not only the celebrity. Around 90 ingredients and NSF for Sport certification genuinely cost more to formulate and verify than a leaner formula. Some of the premium is real.

But not all of it. When a competitor makes the same all-in-one promise — protein, collagen, NAD+, the works — for $33 a month less and without a global icon attached, the most reasonable read is that a meaningful slice of IM8’s price is the marketing, not the powder. That’s not a scandal. That’s how celebrity brands work. You’re allowed to decide the name is worth it. I’m just not going to pretend the name is free.

Where IM8 genuinely wins

A comparison that only trashes the other product is a sales pitch in disguise, and you’d be right not to trust it. So here’s where IM8 is the better pick, no spin:

• You’re a tested athlete. NSF Certified for Sport is the cleaner credential here. If your federation cares, this can be the whole decision.
• You want maximum breadth. If your instinct is “give me everything,” ~90 ingredients is a wider net than Momentum throws, full stop.
• You trust scale. 16,000+ reviews and big self-reported outcome numbers are a real signal of a lot of satisfied users. Some people, reasonably, want the crowd behind their purchase.
• The price genuinely doesn’t move you. If $183 vs $150 is noise in your budget, buy the one with the formulation philosophy you like best — and IM8’s is legitimate.

I mean all of that. IM8 is not a bad product. It’s a good product with a premium attached, and for some people the premium is justified.

The trust question (this is the real fork)

Here’s the part I think actually decides it for the kind of person who reads a 3,000-word comparison before buying a shake.

IM8 leans on aggregate trust signals: celebrity co-founders, thousands of reviews, and — cleverly — “284 clinicians share IM8 without compensation.” That last one is a genuinely good move. But notice what it is: a brand telling you that third parties vouch for it.

What I’m offering is different in kind, not degree. I’m one named person who paid for these products, took them, and is staking my own reputation on the recommendation — including telling you, repeatedly, exactly when to buy IM8 or AG1 instead. If Momentum stopped working for me, I’d stop recommending it and lose the commission. That’s the trade I’ve made, and it’s the only trust signal I think is worth much: skin in the game, in public, with a name on it.

You don’t have to take my word over Beckham’s. But you should know the difference between the two kinds of “trust me.”

My verdict

For a research-literate buyer who hates paying for marketing: Momentum. It does the core job IM8 does — protein, collagen, NAD+, the stack-replacement promise — for about $33 a month less, lets you trial a single bag, and doesn’t ask you to fund a celebrity’s involvement. It’s the one I’ve personally kept in rotation, which is the most honest endorsement I’ve got.

For a tested athlete, a breadth-maximalist, or someone who simply isn’t price-sensitive and likes IM8’s formulation: IM8 is a legitimate choice and I won’t talk you out of it.

If Momentum is your pick, you can check current pricing and flavors here. Order the full one-month supply — that’s two bags, since one bag is only two weeks — use code livebetter at checkout for a discount, and you’ll get free samples of every flavor with your first order. Start with chocolate or berry.

Frequently Asked Questions

Is IM8 worth it?

IM8 is a genuinely well-formulated all-in-one — around 90 ingredients, NSF Certified for Sport, a large base of positive reviews. Whether it’s worth $183/month for the full Beckham Stack depends on how much you value breadth and the brand. If you want the widest ingredient list or certification for competitive sport, it’s defensible. If you mainly want the core actives — protein, collagen, NAD+ — without paying for a celebrity co-founder, Momentum delivers most of the same job for about $33/month less.

Is David Beckham’s IM8 actually good?

Yes — it’s a real, thoughtfully formulated product, not a vanity label. The ingredient breadth is high and it’s third-party certified. The fair criticism isn’t quality, it’s price: at $183/month for the full stack you’re partly paying for the marketing and the Beckham name. The product is good; the question is whether it’s $33-a-month-better than a cheaper all-in-one that covers the same core ingredients.

What’s the difference between IM8 and AG1?

AG1 (~$99/month) is primarily a greens powder — no meaningful protein, no collagen, no NAD+ precursor. IM8 (up to ~$183/month for the Beckham Stack) is a true all-in-one with ~90 ingredients including protein and longevity actives. They’re different categories. If you’re comparing IM8 to AG1, you’re really asking “greens vs. an all-in-one” — compare IM8 to other all-in-one shakes like Momentum instead. (More in my AG1 alternative breakdown.)

Why is IM8 so expensive?

The full Beckham Stack runs ~$183/month (billed roughly $548 every 12 weeks), and the single Daily Ultimate Essentials drink is ~$6/day. Part is genuine — ~90 ingredients and NSF Certified for Sport cost money to formulate and test. Part is the brand: a Beckham co-founder, Giannis and Sabalenka endorsements, and heavy marketing get funded somewhere. A comparable all-in-one like Momentum makes most of the same claims at ~$150/month, which suggests a meaningful chunk of IM8’s premium is the name, not the powder.

Is there a cheaper alternative to IM8?

Yes — Momentum covers the same core ground (grass-fed whey, collagen, an NAD+ precursor, probiotics, electrolytes) at about $150/month for the two-bag monthly supply versus IM8’s $183 Beckham Stack. You can also trial a single bag ($75 subscription / $80 one-time) before committing, where IM8’s full stack is a steeper upfront commitment. It’s third-party tested and HSA/FSA eligible.

Quick disclosure: I’m an affiliate for Momentum, one of the products I compare below. Buy through a link on this page and I earn a commission. I’m telling you up front because the whole point of this piece is honesty — including being honest that I cover products I don’t earn a cent on, and tell you exactly when to buy them instead.

Here’s the short version, because you’re shopping and your time matters:

Most “AG1 alternative” lists are useless, because they’re all the same thing — a cheaper greens powder. If greens is genuinely all you want, skip to the budget greens section and save yourself $50 a month. But if you’re leaving AG1 because $99 a month for just greens feels thin, then a different greens powder isn’t an upgrade. It’s a lateral move. The real question almost nobody answers is: what if you want protein, collagen, and an NAD+ precursor in the same shake? That’s a different product category, and that’s where this gets interesting.

Let me walk you through both honestly.

Why people actually leave AG1

I’ve read a lot of Reddit threads on this (the top “cheaper alternative to AG1” thread has hundreds of replies), and the complaints cluster into three buckets:

The price. AG1 is about $99 a month on subscription. That’s the loudest complaint, and it’s fair. A hundred dollars a month is a real line item.

“It’s just greens.” This is the one people feel but don’t always articulate. You’re spending near $100 and getting a green powder. No protein. No collagen. Nothing that feels like it’s doing structural work. For a lot of people in their late 30s and up, greens stopped being the priority a while ago.

The proprietary blend. AG1 lists 75 ingredients. Seventy-five. Most of them live inside a “blend” with no individual dose disclosed. So you’re trusting that each compound is present at a meaningful amount, not a sprinkle for the label. Maybe it is. You have no way to check.

If your complaint is the first one — just the price — your answer is easy and I’ll give it to you straight in a second. If it’s the second one, you’re not actually looking for an AG1 alternative. You’re looking for a different kind of product and you haven’t been told that yet.

Does AG1 even have protein?

No. And this is the wedge the roundups all miss.

AG1 has under 2 grams of protein per serving. It was never meant to be a protein source — it’s greens and micronutrients. Which is fine, until you realize you’re paying premium money for a daily shake that skips the single macronutrient most people over 35 should be getting more of, not less.

So if you’ve been taking AG1 and also scooping a separate protein powder, and maybe collagen, and maybe an NAD+ precursor — congratulations, you’ve built a four-container morning that costs well over $99 a month and takes up half a shelf. Hold that thought. It matters later.

The honest greens-powder alternatives

I promised I’d be straight, so here it is: if greens is all you want, you’re massively overpaying with AG1. These do the same basic job for less:

• Amazing Grass Green Superfood — roughly $25 a month. It’s been around forever, it’s not fancy, and it covers the greens-and-vitamins base for a quarter of AG1’s price. The taste is grassier. You get what you pay for, and what you pay for is fine.
• Bloom Greens — around $35–40. Flavored, mixes easily, popular for a reason. More of a “I’ll actually drink this” product than a purist’s formula.
• Huel Daily Greens — about $40. A more serious formulation than the budget options, with better transparency than AG1 on several fronts, at well under half the price.

Any of these is a defensible swap if your only beef with AG1 is the cost of greens. I don’t earn anything if you buy them. I’m telling you anyway, because if I pretended the only answer was the product I’m paid on, you’d have no reason to trust the rest of this page.

But notice what every one of these has in common with AG1: they’re still just greens. No protein. No collagen. No longevity actives. You’ve made the greens habit cheaper. You haven’t made your morning do more.

The reframe: greens powder vs. an all-in-one shake

Here’s the shift the entire “AG1 alternative” conversation is missing.

A greens powder and an all-in-one longevity shake are not competitors. They’re different jobs. Comparing them is like comparing a multivitamin to a meal. One fills micronutrient gaps. The other is trying to replace a whole stack of supplements with one scoop.

AG1 — and every greens powder above — lives firmly in the first category. Greens, vitamins, some adaptogens, a probiotic. A daily floor for micronutrients.

The other category — the one nobody on these lists is pointing you toward — is the all-in-one shake that bundles:

• Protein (the thing AG1 skips entirely)
• Collagen (joints, skin, connective tissue — the stuff you make less of past 35)
• An NAD+ precursor (the actual longevity ingredient; NAD+ is what your cells use for energy and repair, and it declines with age)
• Plus the greens-powder supporting cast: probiotics, digestive enzymes, electrolytes, key vitamins

If you’re leaving AG1 because it doesn’t do enough, this is the upgrade. Not a cheaper green powder. A shake that absorbs the four other tubs on your counter.

Momentum: the all-in-one AG1 alternative

The one I’ve personally kept in rotation is Momentum. I’ve written a full honest review of the Momentum longevity shake after four months of daily use, so I won’t repeat all of it here. The short version, in the context of “what replaces AG1”:

It does the things AG1 doesn’t. About 30g of grass-fed whey protein. Grass-fed collagen. An NAD+ precursor. Hyaluronic acid, digestive enzymes, a probiotic co-culture, electrolytes, and vitamins D and K2. The pitch is “two scoops replace 20+ separate supplements,” which is marketing math — but when I added up what I’d actually been buying piecemeal, the overlap was real.

A few things I care about that AG1 falls short on:

It’s transparent and third-party tested. No 75-ingredient mystery blend.

It includes protein and collagen. Which, again, is the entire reason a lot of people are unhappy with paying near $100 for greens.

It tastes like a protein shake, not a lawn. One honest knock from my review: vanilla can come out gritty in a shaker bottle — blend it, or start with chocolate or berry. Otherwise it goes down easy, which matters more than any spec sheet, because the best formula is useless if you quit drinking it.

It is not, to be clear, a greens powder. If your heart is set on a pure greens product, Momentum is not that and I’ll send you back up the page.

The price reality (this is where it gets honest)

Let’s do the math properly, because this is where most comparisons either lie or get lazy.

	What it is	Real monthly cost	Protein?	Collagen?	NAD+?
AG1	Greens powder	~$99/mo	✗	✗	✗
Budget greens (Amazing Grass, Bloom)	Greens powder	$25–45/mo	✗	✗	✗
Momentum	All-in-one shake	~$150/mo (2 bags)	✓ ~30g	✓	✓
IM8	All-in-one shake	$183/mo	✓	✓	✓

A note on that Momentum number, because it trips people up: a bag is $75 on subscription ($80 one-time), but one bag lasts about two weeks at two scoops a day. A full month is two bags — about $150 a month. I’d rather you know the real number now than be surprised at your second reorder. Both bags ship free, the one-month supply comes with free samples of every flavor, and it’s HSA/FSA eligible, which quietly knocks the effective price down if you’ve got those funds.

So is Momentum “cheaper than AG1”? No — and I won’t pretend it is. It’s more, because it’s doing more. The honest comparison isn’t “Momentum vs. AG1.” It’s “Momentum vs. AG1 plus the separate protein, collagen, and NAD+ precursor you’d need to match it.” Run that math and Momentum usually comes in at or under what the stack costs — and it’s one container instead of four.

And if you want the other all-in-one on the market: IM8, the David Beckham shake, makes nearly identical claims for $183 a month. I dug into whether that extra $33 a month buys you anything in my IM8 vs Momentum comparison — short answer, mostly a celebrity on the label.

Who should just stick with AG1

I’d rather lose the click than send you to the wrong product, so here’s who should ignore everything I just said about Momentum:

• You only want greens. If micronutrient coverage is the entire goal and you don’t want protein or collagen in your shake, an all-in-one is overkill. Buy a greens powder — AG1 if you like it, or a budget one to save $50.
• You already eat plenty of protein and take collagen and NAD+ separately, and you like it that way. If the four-container ritual doesn’t bother you and you trust your specific doses, consolidating isn’t a win for you.
• You want the lowest possible price, full stop. Then it’s Amazing Grass at $25 and we’re done. No shame in it.
• You’re sensitive to whey. Momentum is whey-based. That’s a real dealbreaker for some people, and I won’t talk you out of it.

That’s not me hedging. That’s the actual map. Most “honest review” pages can’t bring themselves to tell you when not to buy the thing they’re paid on. I’d rather you trust the recommendation when it does apply.

My pick, and why

If you’re leaving AG1 purely on price and greens is all you wanted: Amazing Grass or Huel Daily Greens. Done. Keep your money.

If you’re leaving AG1 because $99 for just greens never sat right — because you’re playing the longer game with your health and you’re tired of managing a shelf of half-empty tubs — then a cheaper greens powder was never your answer. The all-in-one shake is. And of the two real all-in-one options, Momentum does what IM8 does for $33 a month less, and it’s the one I’ve actually kept drinking.

If that’s you, you can check current Momentum pricing and flavors here. Order the full one-month supply (two bags — remember, one bag is only two weeks), use code livebetter at checkout for a discount, and you’ll get free samples of every flavor to find your favorite. Start with chocolate or berry.

Frequently Asked Questions

Is there a cheaper alternative to AG1?

Yes — if all you want is greens. Amazing Grass runs about $25/month, and Bloom and Huel Daily Greens land in the $35–45 range, versus AG1’s ~$99. They cover the same greens-and-vitamins job for half or less. The catch: they’re all still just greens — no protein, collagen, or NAD+ precursor. If “cheaper” is the only goal, buy a budget greens powder. If you’re leaving AG1 because it doesn’t do enough, a cheaper greens powder is a lateral move, not an upgrade.

Are AG1 alternatives worth it?

It depends what you’re replacing it with. Swapping AG1 for a cheaper greens powder is worth it only if greens were all you wanted. The more interesting move is swapping it for an all-in-one shake that folds in the protein, collagen, and longevity ingredients you’d otherwise buy separately — that’s where an alternative actually does more, not just costs less.

Is AG1 actually worth the money?

AG1 is a well-made greens powder, but at ~$99/month it asks you to trust a 75-ingredient proprietary blend where most doses aren’t individually disclosed. If you value a clean daily greens habit and don’t mind the opacity, it’s fine. If you’re paying near $100 a month, it’s fair to expect more than greens — and AG1 doesn’t include protein, collagen, or an NAD+ precursor.

Does AG1 have protein?

No. AG1 has under 2 grams of protein per serving — it’s a greens and micronutrient powder, not a protein source. If you want protein in your daily shake, you either stack a separate protein powder on top of AG1 or switch to an all-in-one like Momentum that includes about 30g of grass-fed whey alongside greens-style support.

What’s the best all-in-one supplement?

For greens alone, AG1 is the category default. For an actual all-in-one that replaces a stack — protein, collagen, NAD+ precursor, probiotics, electrolytes — Momentum is the one I’ve personally kept in rotation, at about $150/month for the two-bag monthly supply. IM8 makes similar claims at $183/month. The “best” depends entirely on whether you want greens or a stack replacement.

Disclosure first, because that’s the deal: I’m an affiliate for Momentum. If you buy through a link on this page, I earn a commission. I’m telling you that up top because it’s the whole point of how I do this — I only put my name behind things I actually use, and I’d rather you trust the review than wonder what I’m hiding. So here’s the honest version.

I’ve been drinking the Momentum longevity shake every morning for four months. Two scoops, blender, done before I’ve finished reading anything important. This is what I noticed, what I didn’t, what it tastes like, what it costs, and who I think should skip it.

If you’re searching “momentum longevity shake review,” you’ve probably already seen the brand’s own site and a scatter of Reddit threads. Useful, but one’s selling and the others are forty people with forty different mornings. Here’s one person who’s taken it daily, in one place.

What Momentum actually is

Momentum calls itself a longevity shake, which is a phrase doing a lot of work these days. Here’s what’s in the bag, in plain terms:

• Grass-fed whey isolate — about 30g of protein per serving. Real protein, not a token scoop.
• Grass-fed collagen — the joint, skin, and connective-tissue protein most of us stop making enough of past 35.
• An NAD+ precursor — the longevity ingredient. NAD+ is a molecule your cells use for energy and repair, and it declines as you age. You can’t feel it dropping and you can’t feel it topping up, but the research on raising it is genuinely interesting.
• Hyaluronic acid, digestive enzymes, a probiotic co-culture, electrolytes, and vitamins D and K2 — the supporting cast that usually lives in four other tubs on your counter.

The pitch is that two scoops replace 20+ separate supplements. That’s marketing math, but it’s not a lie. When I added up what was actually in it against what I’d been buying piecemeal, the overlap was real.

It’s third-party tested, which matters in a category full of products that have never met an independent lab. And it’s HSA/FSA eligible, which is a small thing that quietly knocks the price down if you have those funds.

What I actually noticed (and what I didn’t)

I’ll separate this the way I separate everything: what I felt, and what I’m taking on faith.

Week one to two: The first real change was boring and welcome — my digestion settled. I’d half-expected the protein-and-fiber load to do the opposite. Instead, things just got more regular. Credit the enzymes and the probiotic, probably. This is the kind of result nobody puts in a hero headline, but it’s the kind you notice every single day.

Week three to four: Steadier morning energy. Not a jolt — I want to be precise here, because “energy” is the most abused word in this industry. I mean the late-morning dip got smaller. I stopped reaching for a second coffee at 11. Could be the protein keeping me full. Could be the electrolytes. Could be that I’d replaced a worse breakfast with a better one. I’m not going to pretend I know exactly which lever moved.

Month two onward: Honestly? A plateau of feeling fine. And I mean that as a compliment. The shake became the least interesting part of my morning, which is what you want from a daily habit. No crashes, no weird aftertaste fatigue, no “do I really have to drink this again.”

What I’m taking on faith: The NAD+ piece. I can’t feel my NAD+ levels, and neither can anyone selling you a precursor. What the research shows is that NAD+ declines with age and that raising it may support cellular repair. What I’ve felt is nothing directly attributable to it — and that’s exactly what I’d expect. This is the long game. If a longevity product promises you’ll feel the cellular stuff in week one, that’s the tell that they’re selling a sensation, not a result.

Taste and texture, real talk

This is the part Reddit cares about most, and they’re right to. The best formula in the world is useless if you can’t get it down every day.

Momentum tastes like a protein shake, not like a lawn. That alone puts it ahead of half the all-in-one products I’ve tried, which tend to taste like someone juiced a multivitamin.

Chocolate is the safe pick and blends smooth. The berry and matcha are the ones I keep reordering. Peanut butter surprised me — those flavors usually taste off, and this one doesn’t.

Now the honest knock: vanilla can come out slightly chunky if you shake it in a bottle instead of blending it. It’s not undrinkable, but it’s grittier than the others. Use a blender and ice and the problem mostly disappears. If you’re a shaker-bottle person who hates texture, skip vanilla and you’ll never notice the issue.

The price, and the math that actually matters

Here’s the part most reviews get wrong, so pay attention: a single bag is $80 one-time, or $75 on subscription — but one bag only lasts about two weeks at two scoops a day. A full month is two bags. That’s why two bags ship free and why I tell people to just order both up front: at two scoops a day you’ll burn through one bag and be out before the month is up. On subscription that’s $150 a month for the real, daily-use supply ($160 if you order one-time). HSA/FSA eligible, which quietly takes a bite out of that.

I’m spelling this out because if you buy a single bag thinking it’s a month, you’ll run dry halfway through and never give it the runway it needs. Two bags is the actual month. Buy the month. And there’s a real perk for doing it: order the full one-month supply and your first order ships with free samples of every flavor, so you can try them all instead of gambling on one.

A hundred and fifty a month sounds like a lot until you do the comparison that matters — not “shake versus nothing,” but “shake versus the stack you’re already buying.” When I added up what I’d been spending on separate protein, collagen, an NAD+ precursor, and a gut blend, I was past $150 and managing four containers and four expiration dates. Momentum came in at or under my actual stack, not more expensive than my imaginary one.

Here’s the comparison people actually want, since “momentum vs AG1” is the other thing you’re probably Googling. AG1 is a greens powder — no protein, no collagen — and runs around $99 a month for far less in the scoop. IM8, the David Beckham shake, runs $183 a month for a comparable all-in-one promise. Momentum’s full month lands at $150 making most of the same claims IM8 does. I’ve looked hard at what that extra $33 a month buys you with IM8, and a lot of it is the name on the label.

So the price isn’t cheap. But in this category, it’s the honest middle — more food than the greens powders, less markup than the celebrity ones.

Most people buy one bag thinking it’s a month (it’s two weeks), pay the one-time price by mistake, and miss the free flavor samples. I put the 4 ordering mistakes — plus my livebetter discount code — on one page so your first order isn’t one of them.

Who should skip it

I’d rather lose the sale than have you buy something that’s wrong for you, so here’s who Momentum is not for:

• You only want greens. Buy a greens powder. Momentum is a full shake; you’d be paying for protein and collagen you don’t want.
• You hate any grit and only use a shaker bottle. You can work around it with a blender, but if that’s a dealbreaker, this is a real friction point.
• You want a week-one transformation. Wrong product, wrong category, wrong mindset. The longevity ingredients here pay off on a timeline measured in months, and the honest results are subtle.
• You’re already dialed in with single-ingredient supplements you trust and enjoy taking. If the four-container ritual doesn’t bother you and the cost pencils out, you don’t need to consolidate.

The verdict

I kept drinking it. That’s the simplest review I can give, and after four months it’s the most honest one.

Momentum isn’t magic, and I’d be suspicious of anyone who told you it was. What it is: a genuinely good-tasting, third-party-tested shake that folded most of my morning supplement stack into one step, settled my digestion, smoothed out my energy, and quietly stopped being something I had to think about. The longevity ingredients are a bet on the long game — a reasonable, research-backed bet, but a bet, and I’ll always tell you that part straight.

If you’re playing the long game with your health and you’re tired of managing a shelf of half-empty tubs, it’s worth understanding. It’s the only all-in-one longevity shake I’ve personally kept in rotation, and at $150 a month against the $183 alternatives, it’s the one I point people to.

If you want to try it, you can check current Momentum pricing and flavors here. One thing I’ll repeat because it trips people up: a bag is two weeks, so grab two bags for a full month — they ship free together and it’s the only way to actually give it the runway. Better still, ordering the full one-month supply gets you free samples of every flavor with your first order, so you can taste your way through all of them before you commit to a favorite. Subscription drops each bag to $75 ($150 for the month) and you can cancel anytime — start with chocolate or berry if you’re not sure.

And use code livebetter at checkout for a discount on that first order — it stacks on top of the free shipping and the flavor samples, so the full month is the cheapest it gets.

Frequently Asked Questions

Is the Momentum longevity shake worth it?

If you’re already buying separate protein, collagen, an NAD+ precursor, and a greens or gut blend, Momentum consolidates most of that into one shake and is worth it on convenience and cost alone. A full month is two bags — about $150 on subscription — because one bag covers roughly two weeks at two scoops a day. If you take nothing now and want one easy daily habit, it’s a reasonable starting point. If you only want greens, it’s overkill — get a greens powder.

What does the Momentum shake taste like?

Better than most all-in-one products, which clears a low bar. Chocolate, berry, and matcha blend smooth. Vanilla can come out slightly chunky in a shaker bottle — blend it instead. It tastes like a protein shake, not like grass.

What’s actually in the Momentum longevity shake?

Grass-fed whey isolate (~30g protein), grass-fed collagen, an NAD+ precursor, hyaluronic acid, digestive enzymes, a probiotic co-culture, electrolytes, and vitamins D and K2. Two scoops are positioned to replace 20+ separate supplements. Third-party tested and HSA/FSA eligible.

Is Momentum better than AG1?

They do different jobs. AG1 is greens with no protein. Momentum is a full shake — protein, collagen, NAD+ — meant to replace a stack. Want greens? AG1. Want one drink that stands in for your breakfast supplements? Momentum. At similar monthly cost, Momentum gives you more actual food.

How much does the Momentum longevity shake cost?

$80 a bag one-time, or $75 a bag on subscription. A bag lasts about two weeks at two scoops a day, so a full month is two bags — roughly $150 on subscription, with both bags shipping free and free flavor samples on your first order. Use code livebetter at checkout for a discount, and note it’s HSA/FSA eligible too.

How long before you notice anything from Momentum?

For me: digestion settled in the first week or two, steadier morning energy around weeks three to four. The NAD+ and other longevity ingredients work on a timeline you can’t feel day to day. That’s the long game — anyone promising a week-one transformation is selling you a feeling, not a result.
