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.
📋 Before you order: the 90-second cheat sheet
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.
