L-Leucine

L-Leucine is an essential branched-chain amino acid (BCAA), (S)-2-amino-4-methylpentanoic acid, supplied by Nustras as a white crystalline powder, granules and instantised or micronised grades for the nutrition and food sectors. It is one of the three BCAAs together with isoleucine and valine.

It is formulated into sports-nutrition powders, BCAA and essential-amino-acid blends, protein fortification of foods and beverages, medical and enteral nutrition, nutritional formulas, capsules and tablets, and feed premixes. Instantised grades disperse readily in drink mixes; micronised grades suit tablets and fine blends; vegan (fermentation-derived) grades are available.

The material is a white crystalline powder or granule with CAS number 61-90-5, molecular formula C6H13NO2 and molecular weight 131.17. Assay is standardised to specification and determined by titration or HPLC, with identity confirmed by infrared and specific rotation to compendial monograph requirements; heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies L-leucine in bulk commercial quantities, in food-grade bags and fibre drums, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. L-Leucine is an accepted food and supplement ingredient in major markets; buyers confirm the permitted level and claim for their application. Contact us for grade, pricing per kilogram and lead time.
