Marketing Claims Vs. Reality
NSF Certified for Sport.
Found in NSF's Certified for Sport database on Oct 11, 2026 as 'Vital Aminos Tropical Punch', listing 1505442, lot number 'All'.
13 amino acids, including all nine essential amino acids.
The panel lists thirteen entries; nine are essential amino acids, one of the thirteen is alpha-ketoglutaric acid.
Supports muscle growth and repair.
Free-form EAAs stimulate muscle protein synthesis (Ferrando 2023). How much that adds to muscle gain depends on the protein you already eat (Morton 2018).
What Our Test Actually Found
What the certification covers
NSF Certified for Sport means the contents were checked against the label and screened for banned substances. Many products are certified lot by lot; this listing covers all lots, so there is no lot number to match.
A leucine-forward formula
45% of the EAA content is leucine, the amino acid that switches on muscle protein synthesis. Older adults need a larger share of leucine to get the same response (Ferrando 2023), which makes this profile a reasonable choice past 50.
You pay for the seal
Per 10 g of EAAs this costs $2.75 against $0.86 for NAKED. If you are not tested, that difference buys a flavor, a stevia sweetener and the certification.

- Every amount printed
- No artificial sweeteners or colors
- $2.75 per 10 g of EAAs
- 5.6 g of EAAs per scoop, under 6 g
- Methionine 50 mg and tryptophan 20 mg

- You want every amount printed and a certifier behind it
- Price per gram matters: NAKED delivers 9.25 g for about half the price per serving
- You want a full 6 g or more of EAAs in one scoop
- You want an unflavored powder
NSF Certified for Sport for all lots is the reason to choose it, and the 2.5 g of leucine per scoop is the highest leucine share here. The total, 5.6 g of EAAs, sits just under the 6 g used in Børsheim 2002, and methionine and tryptophan are low. It is the second most expensive product on the list per gram.
Momentous Vital Aminos is the product to buy if you are tested. NSF's Certified for Sport database lists it for all lots (listing 1505442, checked Oct 11, 2026), and the NSF mark is printed next to the Supplement Facts panel. One 11.5 g scoop holds 5,570 mg of essential amino acids: 2,500 mg leucine, 725 mg lysine HCl, 625 mg each of isoleucine and valine, 375 mg threonine, 350 mg phenylalanine, 300 mg histidine HCl, 50 mg methionine and 20 mg tryptophan. It adds four more: 525 mg arginine, 470 mg alpha-ketoglutaric acid, 150 mg cystine and 30 mg tyrosine. Flavors are natural and the sweetener is organic rebaudioside A. At $45.99 for 30 scoops on Oct 11, 2026 it costs $2.75 per 10 g of EAAs, more than three times NAKED.
The EAA for tested athletes
Momentous earns its place with one thing none of the cheaper tubs has: NSF Certified for Sport for every lot, confirmed at the certifier. The formula is leucine-heavy and openly labelled. It is also expensive per gram and a little short of 6 g per scoop, so if nobody tests you, NAKED gives you more amino acids for less.
If This Doesn’t Fit — Try These
01NAKED EAAs
If you want essential amino acids in a dose that matches the research, this is the tub: 9.25 g with 2.4 g of leucine, all nine amounts printed, nothing added but sunflower lecithin.
02Nutricost EAA Powder
For sixty cents a scoop you get 8 g of EAAs, plenty of leucine and a label that states third-party testing.
04Xtend EAA
Xtend EAA is honest on the panel and pleasant in the glass.

PMID 37800468 — International Society of Sports Nutrition Position Stand: Effects of essential amino acid supplementation on exercise and performance. The ISSN position stand concludes that free-form EAAs raise blood EAA levels quickly and stimulate muscle protein synthesis, that the response starts at 1.5 to 3.0 g at rest and plateaus at about 15 to 18 g, that non-essential amino acids are not needed for it, and that aging calls for a larger share of leucine.
- [2] Børsheim E, et al. Am J Physiol Endocrinol Metab. 2002;283(4):E648-57. PMID 12217881 — Essential amino acids and muscle protein recovery from resistance exercise. 6 g of oral essential amino acids taken 1 and 2 hours after resistance exercise raised net muscle protein balance; the response was double that of an earlier mix of 3 g EAA plus 3 g non-essential amino acids, pointing to a dose-dependent effect of EAAs.

PMID 28698222 — A systematic review, meta-analysis and meta-regression of the effect of protein supplementation on resistance training-induced gains in muscle mass and strength in healthy adults. A meta-analysis of resistance-training trials found that protein supplementation adds to gains in muscle mass and strength, and that the benefit levels off at a total intake of about 1.6 g of protein per kg of body weight a day.
