L-Isoleucine

L-Isoleucine is an essential amino acid and one of the three branched-chain amino acids, alongside leucine and valine, supplied by Nustras as a powder and also as granules, an instantised grade and a micronised grade, all suitable for vegan formulations, and used as an amino-acid ingredient for supplements, foods and feed.

It is formulated into branched-chain amino-acid blends and sports-nutrition powders, into protein and amino-acid supplements in capsule, tablet and powder form, into functional foods and beverages, into medical and enteral nutrition formulations, into cell-culture media, and into animal-feed and pet-food products.

The material is a powder, with CAS number 73-32-5, molecular formula C6H13NO2 and a molecular weight of 131.17. Assay, specific rotation, loss on drying, pH and residue on ignition are standardised to specification; identity and assay are confirmed by infrared spectroscopy and titration or HPLC, and heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies L-isoleucine 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-Isoleucine is an accepted food and supplement ingredient in major markets; buyers confirm the permitted level and declaration for their application.
