HelloPharmacist Scorecard of BCAA 1000 by ON Optimum Nutrition
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.

Formula
The power of branched chain amino acids L-Leucine, L-Isoleucine and L-Valine are commonly grouped together and referred to as branched chain amino acids, or BCAAs, because of their unique branched chemical structure. BCAAs are essential, meaning they must be consumed through the diet since the human body cannot make them from other compounds.
One 2-capsule serving provides 1000 mg of BCAAs.
1000 mg branched chain amino acids per 2 capsule serving 2:1:1 ratio of L-Leucine, L-Isoleucine and L-Valine
