L-Carnitine Fumarate

L-Carnitine fumarate is the salt of L-carnitine with fumaric acid, supplied by Nustras as a white crystalline powder and a stable, non-hygroscopic form of L-carnitine for dietary supplements, sports nutrition and functional foods. L-Carnitine is a naturally occurring quaternary ammonium compound derived from the amino acids lysine and methionine; the fumarate salt is preferred where the free base would take up moisture.

It is formulated into capsules, tablets and powdered drink mixes, into sports-nutrition and weight-management category products, into functional foods and beverages, and into premixes for the supplement sector. A vegan grade is available.

The material is a white crystalline powder with CAS number 220349-64-4, molecular formula C18H36N2O10 and molecular weight 440.5. L-Carnitine and fumaric acid content are standardised to specification and determined by HPLC or titration, with identity confirmed by infrared and specific rotation; heavy-metal and microbial limits are supplied to specification and confirmed on each lot's certificate of analysis.

Nustras supplies L-carnitine fumarate 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-Carnitine fumarate is an accepted supplement ingredient in major markets; buyers confirm the permitted level, the L-carnitine equivalence and the claim for their application.
