Is NutraBio EAA Pure underdosed?

Verdict

7.84 g per servingone dose · studies use 10–12 g of essential amino acids

Below research dose

One serving contains 7.84 g; studies use 10–12 g in one dose. The label's directions allow 1–3 servings a day.

One serving gives 7.84 g, so reaching the low end of what studies use (10 g) takes 1.3 servings at once; it ranks 7th of 20 EAA supplements here by dose.

To reach the research dose. It would take 2 servings at once (2 scoops), 15.68 g, to reach the 10 g studies use.

Amino acids, one by one

All nine essential amino acids are on the label. 4 of 9 reach what a 10 g dose shaped like the WHO adult requirement pattern holds. The lowest is methionine: 13 mg, 2% of 815 mg.

How this works: the WHO's adult requirement for each essential amino acid (WHO/FAO/UNU 2007, Table 23), scaled to a 10 g dose, the low end of the 10–12 g of essential amino acids in one dose in the ISSN's 2018 review. No study gave these amino acids one at a time at these amounts: it shows how a serving's mix compares with what the body needs, not a dose of each. The WHO figures for methionine and phenylalanine include cysteine and tyrosine, which the body can make; tyrosine is counted when the label lists it. Salt forms are counted as the amino acid in them (lysine hydrochloride as 80% lysine), and a DL form as half L.
