Registry check · EAA
Does anyone independently verify EAA supplements?
1 of these 6 products are confirmed in NSF/ANSI 173, which puts this category in the minority with any verified option at all. The other 5 are not listed anywhere we can check — not evidence against them, only an absence of independent confirmation.
Certification is not a dosing guarantee. Across the whole catalogue, certified products reach the clinically studied dose 57% of the time and uncertified ones 71% — a gap too small to mean anything (Fisher p = 0.185). Read the EAA dose column either way.
6 checked against all 5,317 US NSF, USP and Informed Sport listings, 2026-08-25. Full method and limitations.
What 6 EAA labels show

The evidence · EAA
What the published reviews of EAA concluded
- Effects of Protein, Essential Amino Acids, B-Hydroxy B-Methylbutyrate, Creatine, Dehydroepiandrosterone and Fatty Acid Supplementation on Muscle Mass, Muscle Strength and Physical Performance in Older People Aged 60 Years and Over. A Systematic Review on the Literature. · The journal of nutrition, health & aging, 2018
“This systematic review showed a limited effect of nutritional supplementation on muscle mass, muscle power and physical function. Inconsistent positive effects were observed for some specific supplementations but the results only concerned one aspect of the muscle.”
- The effect of the diet of nitrogen-free analogs of essential amino acids on chronic kidney disease deterioration: A meta-analysis. · Therapeutic apheresis and dialysis : official peer-reviewed journal of the International Society for Apheresis, the Japanese Society for Apheresis, the Japanese Society for Dialysis Therapy, 2022
“The very low-protein diets supplemented with nitrogen-free analogs had significantly better kidney functions results compared to the conventional low-protein diets in subjects with chronic kidney disease.”
- Dileucine-supplemented essential amino acids support whole-body anabolism after resistance exercise and serum-stimulated cell-based anabolism. · Journal of the International Society of Sports Nutrition, 2025
“Dileucine-supplemented EAA and BCAA support greater whole-body anabolism compared with COL after resistance exercise independent of attenuation in urinary estimates of myofibrillar protein breakdown. Exploratory ex vivo experiments reveal a potential anabolic effect of DIEAA in stimulating MPS.”
- Randomized double-blind trial of oral essential amino acids for dialysis-associated hypoalbuminemia. · Kidney international, 2000
“Oral EAAs induce a significant improvement in the serum albumin concentration in hemodialysis but not peritoneal dialysis subjects. Further study of their long-term effects on morbidity and mortality is warranted.”
Method: PubMed searched in humans for systematic reviews, meta-analyses and randomised trials with EAA in the title; these 4 of the 4 that qualified are shown with the authors’ own conclusion quoted rather than summarised. What it cannot tell you: whether EAA will work for you — each of these reports an average across trials published 2000–2025, and null findings are shown here as readily as positive ones.
