Frequently Asked Questions

What is L-Carnitine used for?

L-Carnitine (CAS 541-15-1), also called levocarnitine, is a quaternary ammonium compound (C7H15NO3) supplied as an ingredient for dietary supplement and functional food and beverage formulations. In cosmetics, Industry references record cleansing and foam-boosting functions. RawSource supplies USP, Kosher-certified free base in bulk.

Is RawSource L-Carnitine vegan and Kosher?

This free-base material is offered to USP specification with Kosher certification. Synthetic L-carnitine free base is produced without animal-derived inputs; we can provide the Kosher certificate and origin/manufacturing documentation on request so you can confirm it against your own labeling requirements.

What is the difference between L-carnitine free base and L-carnitine L-tartrate?

The free base (CAS 541-15-1) is pure L-carnitine and is hygroscopic, while the L-tartrate salt (CAS 36687-82-8) is non-hygroscopic and favored for solid dosage forms. The free base delivers higher carnitine content per gram; the tartrate offers better handling in dry blends. We stock both and can quote either.

How is L-Carnitine free base sold in bulk?

It is supplied as a crystalline/powder raw material in industrial packaging sized for supplement and functional-beverage manufacturing; because it is hygroscopic, packaging is moisture-protective. Contact us for bulk pack sizes, minimum order quantity, lead time, and a current quote. CoA and SDS accompany every shipment.
