“Everything they make is third-party tested and certified, so I know the ingredients are not contaminated, are of the highest quality possible, and are dosed correctly in the bottle. I spent years vetting Momentous before officially partnering with them — they're one of the best in the world at providing clinically meaningful dosages.”
— Dr. Andy Galpin, PhD, exercise physiologist and member of the Momentous Scientific Advisory Board
Kion and Momentous are the two brands that come up most often when people ask about “clean” or transparent supplement companies — but they're built for slightly different customers. Momentous is the brand in 100% of NFL locker rooms with a scientific advisory board that reads like a Huberman Lab guest list. Kion is the everyday wellness brand co-founded by biohacker Ben Greenfield. I bought aminos and creatine from both and used each for three weeks to see where they actually diverge.
Kion vs Momentous: The Basics
Kion was co-founded in 2017 by Ben Greenfield, MS, CSCS, and Angelo Keely, built around full ingredient transparency for everyday health-conscious consumers — its lineup spans aminos, protein, organic coffee, creatine, omega-3, sleep, and immune support. Momentous launched in 2018 and relaunched in 2021 under CEO Jeff Byers, a former NFL offensive lineman, with formulations developed alongside a scientific advisory board that includes Dr. Andy Galpin, Dr. Stacy Sims, and Dr. Andrew Huberman. Nearly every Momentous product carries NSF Certified for Sport, the certification recognized by the NFL and MLB, and the brand is used by more than 150 professional and college sports programs.
Side-by-Side Product Breakdown
Kion Aminos — $42.46 (30 servings, ~$1.42/serving)
9 fully disclosed essential amino acids, 4 flavor options, stimulant-free. Manufactured in a cGMP, NSF-certified facility, though the finished product itself isn't NSF Certified for Sport.
Momentous Vital Aminos — $45.99 (30 servings, ~$1.53/serving)
13 amino acids total — all 9 EAAs plus 4 additional aminos selected for performance and recovery. NSF Certified for Sport on every batch, a real advantage for tested athletes.
See Why Kion Is the Better Everyday Pick
Full transparency, broader product range, and a lower price per serving.
My Real Experience, Week by Week
Weeks 1–3: Kion Aminos and Coffee
I ran my usual routine — Kion Aminos in the morning, a second serving post-workout — and logged the now-familiar drop in next-day leg soreness, from 7/10 down to 4/10 by day 12. The Kion side of this test felt like part of my regular life: mixing a flavored scoop, brewing a cup of the medium roast coffee alongside it.
Weeks 4–6: Momentous Vital Aminos and Creatine
I switched to Momentous Vital Aminos (Tropical Punch) plus their Creapure creatine monohydrate for the next three weeks. Recovery tracked almost identically — a 4/10 soreness rating by day 33 after a heavy leg day, consistent with what I'd seen on Kion. The creatine mixed noticeably finer than a budget creatine I'd used previously, with zero grit at the bottom of the glass, which matched the brand's reputation for testing rigor.
The Honest Comparison
Recovery outcomes were essentially a wash between the two brands over three weeks each. Where they genuinely diverged was scope and price: I could get coffee, protein, and aminos from Kion in one order at a lower combined cost, while Momentous required paying a premium that's really buying you the NSF Certified for Sport testing layer — valuable if you need it, less relevant if you don't.
Where Kion Wins
Lower price per serving across comparable products. Kion Aminos runs about 7% cheaper than Momentous Vital Aminos, and that gap holds across most of the overlapping product lines.
Broader everyday lineup. Kion covers coffee, sleep, and immune support in addition to performance products — Momentous stays narrowly focused on athletic performance.
Full ingredient transparency without a certification premium. You still get every amino acid disclosed by the milligram, just without paying for banned-substance testing most non-competitive users don't need.
60-day money-back guarantee. A longer trial window than most Momentous retail purchases allow.
Things to Know Before You Choose
Kion isn't NSF Certified for Sport. If you're a tested athlete, that certification gap is real and matters for eligibility, not just marketing.
Momentous has a stronger science-communicator advisory board. Dr. Andy Galpin, Dr. Stacy Sims, and Dr. Andrew Huberman give Momentous a level of public scientific vetting Kion doesn't have to the same degree.
Kion's brand image leans more “influencer,” Momentous leans more “clinical.” Some buyers will prefer one positioning over the other independent of the actual ingredients.

Honestly, Momentous earns its premium if you specifically need NSF Certified for Sport or want a brand built entirely around a clinical science advisory board. But for the majority of everyday buyers who aren't drug-tested athletes, Kion delivers comparable transparency, a wider everyday product range, and a lower price.
Who Should Buy Kion
If you want one brand that covers aminos, protein, coffee, and recovery for everyday health and fitness — without paying a premium for certifications you don't need — Kion is the more practical choice. It's also the better fit if flavor variety and a broader everyday lineup matter to you.
When Momentous Might Fit Better
If you're a tested competitive athlete who needs NSF Certified for Sport, or you specifically want a brand vetted publicly by a well-known science advisory board, Momentous is the more defensible choice for your situation.
Final Verdict: Kion, 4.5/5
Both brands are legitimately trustworthy — this isn't a case of one being “clean” and the other not. Momentous has the edge for certified athletes who need NSF Certified for Sport. But for most everyday buyers, Kion offers comparable transparency, a broader everyday lineup, and a lower price per serving, which makes it the better all-around choice for the way most people actually supplement.

Who is behind each brand?
Kion was co-founded by Ben Greenfield, MS, CSCS, a human performance consultant and author. Momentous is led by CEO Jeff Byers, a former NFL offensive lineman, with formulations developed alongside a scientific advisory board including Dr. Andy Galpin, Dr. Stacy Sims, and Dr. Andrew Huberman.
Which brand has a wider product range?
Kion's lineup covers a broader everyday-life range including aminos, protein, organic coffee, sleep, and immune support. Momentous focuses more tightly on performance and recovery: protein, creatine, aminos, omega-3, and sleep support for athletes.
Is Momentous only for professional athletes?
No, anyone can buy Momentous products, but the brand's testing rigor and marketing are clearly aimed at competitive and tested athletes who need banned-substance certification.
Which brand tastes better?
This comes down to personal preference, but Kion's amino powders and coffee lineup are generally rated as more approachable for daily, non-training use, while Momentous products are formulated primarily with performance function in mind.
Which one should I actually buy?
If you're a tested competitive athlete who needs NSF Certified for Sport, Momentous is the safer choice. For most everyday health-conscious buyers who want a broader, more affordable, fully transparent product line, Kion is the better overall fit.
