Nutricost EAA Capsules offer a straightforward way to supplement your diet with all nine essential amino acids, including the three branched-chain amino acids (BCAAs) that are popular among athletes and fitness enthusiasts. Each serving of two capsules provides 1200mg of EAAs, making it a convenient option for those who prefer pills over powders. This supplement is particularly suitable for vegans, vegetarians, or anyone looking to ensure they get a complete amino acid profile without relying on animal products.
The standout feature of Nutricost EAA Capsules is the quality assurance behind the product. Each batch is tested by independent, ISO-accredited laboratories, and the manufacturing facility is GMP compliant and FDA registered. This commitment to safety and purity is crucial for a supplement you take daily. Additionally, the formula is vegan, non-GMO, and gluten free, catering to a wide range of dietary restrictions. The inclusion of all nine EAAs, not just BCAAs, sets it apart from simpler amino supplements.
In terms of design and build, the capsules are standard size and easy to swallow. The bottle contains 240 capsules, providing 120 servings at the recommended two-capsule serving size. This makes it a cost-effective choice compared to many liquid or powder alternatives. The packaging is simple but functional, with a child-resistant cap and clear labeling. There are no artificial colors or flavors, which is a plus for those sensitive to additives.
One potential drawback is that the serving size requires two capsules, which might be a minor inconvenience for those who prefer one-capsule supplements. Also, because the product is relatively new on the market with no customer reviews yet, it lacks the social proof that helps some buyers make a decision. 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.

Buying Guide
Complete Amino Profile
When selecting an EAA supplement, ensure it contains all nine essential amino acids. Some products only offer branched-chain amino acids (BCAAs), which are a subset. A full spectrum supports muscle protein synthesis more effectively. Look for blends that include L-Leucine, L-Isoleucine, L-Valine, plus others like L-Lysine and L-Methionine. For a deeper dive into what nutrients support muscle function, see our article on what nutrients support muscle function.
Form and Convenience
EAAs come in capsules, powders, and drink mixes. Capsules offer precise dosing and portability, while powders allow you to adjust serving size and mix with water or your favorite beverage. Consider your daily routine: if you are always on the go, capsules may be easier. If you prefer a refreshing drink post-workout, a powder mix could be ideal.
