Nutricost, L-Leucine, Unflavored, 17.9 oz (500 g)

L-Leucine is an oral powder preparation. The documented 1 Scoop (5 g) serving provides L-Leucine 5 g. Leucine is an essential branched-chain amino acid involved in protein synthesis and nutrient signalling associated with muscle protein turnover. This preparation supplies leucine as an individual amino acid rather than a complete essential-amino-acid mixture. Its role complements protein nutrition, without implying that leucine alone provides every substrate needed to synthesise complete proteins.

As a dietary supplement, mix 1/2 - 1 scoop with 6-10 oz of water and take daily on an empty stomach or as directed by your healthcare professional. On workout days, take before, during, or after exercise.
