HelloPharmacist Scorecard of Branched-Chain Amino Acids by NOW Sports
Four independent checks of what is known — a summary of the available information, not a grade of the product itself.
By FDA rules, dietary supplements can’t claim to treat, cure, or prevent disease — so labels speak in careful marketing language. We discern each product’s intended use from its name, label claims, and label statements, then grade the clinical evidence for that use. How these ratings are computed
None of the active ingredients could be matched to our evidence database, so intended use can't be graded.
Why this rating?
- None of the active ingredients could be matched to a HelloPharmacist monograph, so intended use can't be graded against our evidence data.
Every active ingredient lists its own amount on the label.
Why this rating?
- The label discloses an exact amount for 3 of its 3 active ingredients.
- No proprietary blends here — you can verify the dose of every single component.
None of the active ingredients could be matched to our interaction database.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was nothing to check interactions against.
None of the active ingredients could be matched to our safety data.
Why this rating?
- We couldn't match any ingredient to a HelloPharmacist monograph, so there was no safety data to measure.

Suggested/Recommended/Usage/Directions
Suggested Usage: Take 4 capsules twice daily before meals or exercise.
Formula
The branched-chain amino acids (BCAAs), leucine, isoleucine and valine are essential amino acids, and thus cannot be made in the body. BCAAs are critical for muscle protein synthesis, and because BCAAs can be used as fuel during intensive exercise, BCAA supplementation can help to preserve existing muscle tissue. In addition, BCAAs can support the recovery process by promoting the normal repair processes that take place after exertion. BCAAs also play an important role in the maintenance of proper immune system function and the support of healthy aging.
