HelloPharmacist Scorecard of Leucine by NutraKey
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 1 of its 1 active ingredient.
- 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?

Formula
Leucine is an essential amino acid As an essential amino acid, Leucine cannot be made by the body, and must be acquired through food or dietary supplements. Leucine is classified as a branched-chain amino is (BCAA). It comprises about 8% of the total amino acids in your body's protein structures as the fourth most concentrated amino acid in skeletal muscle tissue.
This makes Leucine especially important for body builders and other athletes that demand explosive strength.
The branched chain amino acids: valine, leucine, and isoleucine enhanced protein synthesis in liver cells and muscle cells and help promote muscle recovery after exercise. BCAAs contibute to energy production in the body by being oxidized in the cell's mitochondria. BCAAs are used by body builders and athletes to produce and anabolic effect and assist in the repair of micro-tears in muscle tissue that are a normal result of exercise. Leucine is thought to be the most effective BCAA for preventing the body's burning of muscle stores for energy during intense workouts because it's utilized more quickly than isoleucine or valine.
