One potential drawback is that the serving size requires two capsules, which might be a minor inconvenience for those who prefer one-capsule supplements.

However, the Nutricost brand has a solid reputation for quality supplements, and the third-party testing mitigates some uncertainty.

Overall, Nutricost EAA Capsules are a reliable choice for anyone needing a complete essential amino acid supplement in capsule form.
