What Is L-Carnitine?
L-Carnitine base is the free-base ingredient identified by CAS 541-15-1. It is supplied as white crystalline material with a specified titration assay of 98–102%.
Carnitine base is different from L-carnitine tartrate, fumarate and acetyl-L-carnitine. These forms contain different proportions of carnitine and cannot be substituted by equal weight without calculation. For nutrition ingredient development, selecting the stated base form keeps the ingredient identity and formulation quantities aligned with the technical specification.

L-Carnitine Applications
Capsules and tablets
L-carnitine base can be assessed for suitable capsule and tablet blends. Confirm the free-base identity rather than substituting a carnitine salt by equal weight.
Nutrition powder blends
In nutrition powder development, calculate the contribution of the selected base grade and evaluate its mixing behaviour in the complete recipe.
Formulation evaluation
Use the titration assay and identity specification when comparing samples and bulk offers; specify L-carnitine base in the enquiry.
