NAKED EAAs Unflavored Review
#1 of 7 · Best Overall✓ Label verified · Supplement Facts read Oct 11, 2026Real retailer photo, cut out. Label unedited.
Buy it if you want the biggest fully disclosed EAA dose and do not need a flavor. 9.25 g of EAAs with 2.4 g of leucine per serving is well above the 6 g that raised muscle protein balance after training in Børsheim 2002, and every amino acid amount is on the panel.

Marketing Claims Vs. Reality
All nine essential amino acids, 9.25 g per serving.
The panel lists nine amino acids that add up to 9,250 mg per 10 g serving.
2:1:1 ratio of leucine, isoleucine and valine.
The panel prints 2,400 mg leucine and 1,200 mg each of isoleucine and valine.
Pharmaceutical grade.
This is the brand's own wording in the listing. No certificate, lab or standard is named on the label, so there is nothing to check it against.
Promotes optimal muscle protein synthesis.
Free-form EAAs do stimulate muscle protein synthesis (Ferrando 2023). 'Optimal' is marketing, and if your diet already supplies enough protein the added effect on muscle gain is small (Morton 2018).
What Our Test Actually Found
The dose is the reason it ranks first
At rest, muscle protein synthesis responds to as little as 1.5 to 3 g of EAAs and levels off at about 15 to 18 g (Ferrando 2023). After training, 6 g raised net muscle protein balance (Børsheim 2002). NAKED gives 9.25 g in one serving, which no other product here reaches without a second scoop.
Nothing is hidden, and nothing is tested in public
The panel is as open as a label gets: nine amounts and one excipient. The other side of that is testing. The label and listing name no third-party lab and the product is not in NSF's Certified for Sport database, so a drug-tested athlete should pick a certified product instead.
Unflavored means bitter
Free-form amino acids taste bitter, and this tub has no flavor or sweetener to cover it. Mix it into juice or a flavored drink if plain water is too much.
Full analysis: all pros & cons (9), buy if / skip if
- 9.25 g of EAAs per serving, the most on the list
- 2.4 g of leucine per serving
- Every amino acid amount printed
- Only one other ingredient
- 50 servings a tub at $0.86 per 10 g of EAAs
- No third-party testing statement
- Not NSF Certified for Sport
- Unflavored and bitter
- Two scoops per serving
- You want 9 g of EAAs in one serving
- You want every amino acid amount printed
- You want no sweetener, flavor or color
- You are drug-tested and need a certified product: Momentous is the NSF Certified for Sport pick
- You cannot drink bitter, unflavored aminos
- You already eat 1.6 g of protein per kg a day and want a clear extra benefit
9.25 g of EAAs with 2.4 g of leucine per serving is well above the 6 g that raised muscle protein balance after training in Børsheim 2002, and every amino acid amount is on the panel. It is unflavored, so expect the bitter taste of free amino acids. The label carries no third-party testing statement, which is the one reason it does not score higher.
NAKED EAAs is the product on this list that reads most like the amino acid mixtures used in the research. A 10 g serving, about two scoops, delivers 9.25 g of essential amino acids: 2,400 mg leucine, 1,200 mg each of isoleucine, valine, lysine and threonine, 900 mg methionine, 450 mg each of phenylalanine and histidine, and 250 mg tryptophan. The panel prints every one of those amounts, and under other ingredients it lists sunflower lecithin and nothing else. The tub holds 50 servings and cost $39.99 on Amazon US on Oct 11, 2026, which is $0.86 per 10 g of EAAs. What it lacks is a testing statement: neither the label nor the listing names a third-party lab or a certifier.
The fullest, most open EAA label on the list
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. Take one serving around training or between meals that are low in protein. If you are drug-tested, buy Momentous for its certification. If you already eat enough protein, expect a small effect from any EAA product.
If This Doesn’t Fit — Try These
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.
03Momentous Vital Aminos
Momentous earns its place with one thing none of the cheaper tubs has: NSF Certified for Sport for every lot, confirmed at the certifier.
04Xtend EAA
Xtend EAA is honest on the panel and pleasant in the glass.
Quick Answers
How much leucine is in NAKED EAAs?
2,400 mg per 10 g serving, printed on the Supplement Facts panel, alongside 1,200 mg each of isoleucine and valine.
Is NAKED EAAs third-party tested?
The label and the Amazon listing carry no third-party testing statement, and the product is not listed in NSF's Certified for Sport database (checked Oct 11, 2026). If you need a certified product, Momentous Vital Aminos is listed there.
Do I need EAAs if I use protein powder?
Probably not. A scoop of whey already contains all nine essential amino acids, and total protein of about 1.6 g per kg a day is where the benefit of extra protein levels off (Morton 2018). EAAs are useful when a meal is low in protein, when you train fasted or when you are cutting calories.

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.

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.

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.
