L-Carnitine L-Tartrate

L-Carnitine L-tartrate is a stable salt of L-carnitine with L-tartaric acid. L-Carnitine is a naturally occurring compound that the body forms from the amino acids lysine and methionine. Nustras supplies it as a white crystalline, vegan powder, used as an ingredient in sports-nutrition and dietary-supplement products.

It is formulated into sports-nutrition powders and capsules, amino acid and pre-workout blends, tablets, functional beverages and drink powders, and nutrition bars. The tartrate salt is less hygroscopic than L-carnitine base, which makes it the usual choice for dry powders and tablets.

The material is a white crystalline powder (CAS 36687-82-8, C18H36N2O12, molecular weight 472.5), supplied to food grade (GB 1903.60-2023), with an assay of L-carnitine 67.2–69.2% and L-tartaric acid 30.8–32.8%. Assay is confirmed by HPLC or titration on each lot, with identity confirmed by infrared spectroscopy 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 L-tartrate in bulk commercial quantities, in sealed buckets, to manufacturers and formulators internationally, with a certificate of analysis, specification sheet and country-of-origin documentation on every lot. L-Carnitine L-tartrate is an accepted supplement and food ingredient in major markets; buyers confirm the permitted level and claim for their application.
