Description
COA-BACKED NUTRITIONAL INGREDIENT
L-Citrulline for B2B Formulation
L-Citrulline is supplied as a single-entity amino acid for B2B nutrition, beverage and supplement formulation. The purchasing definition is the declared assay, the impurity profile and the physical form rather than a botanical identity.

Buyer Decision Guide
L-Citrulline is specified on assay, specific rotation or chiral purity where relevant, and on heavy metal and microbiological limits. Confirm which of these your finished-product specification actually controls before approving a grade.
- Confirm assay basis and analytical method
- Check the salt or free-form identity: L-Citrulline
- Review specific rotation or chiral purity if applicable
- Confirm heavy metal and microbiological limits
How This Grade Differs
L-Citrulline is a single-entity amino acid. It is not interchangeable with the racemic or salt form of the same molecule, and not with a plant extract that merely contains it. Compare assay basis, salt form and impurity profile when substituting.
Compare these related grades before approval:
For a substitution review, compare botanical identity, plant part, assay target, analytical method, physical form and the current offered-batch COA.
