L-Citrulline DL-Malate

What Is L-Citrulline DL-Malate?

L-Citrulline DL-Malate is a combination ingredient containing L-Citrulline (the amino acid) bound with DL-Malic acid (the racemic mixture of L-Malic and D-Malic acid). The L-Citrulline component provides the nitric oxide pathway benefit described in Section 26 (L-Citrulline): it converts to L-Arginine in the kidneys, which then serves as the substrate for nitric oxide synthase. The malate component is a Krebs cycle intermediate involved in aerobic energy production — there is theoretical rationale that it may contribute to reduced fatigue during sustained exercise, though isolating this effect from citrulline's own contribution is methodologically difficult.

The important distinction for formulators: most published pre-workout performance research uses citrulline malate at doses of 6–8 g (as total citrulline malate), not pure L-Citrulline base at equivalent doses. If label claims are intended to reference this research, the specific form must match.

Common Mistakes

Citing citrulline malate research on a label for a product containing pure L-Citrulline base (or vice versa). These are different products with different compositions — evidence should correspond to the specific ingredient used.

Using 8 g citrulline malate dose references without checking the citrulline content at that dose. 8 g of 2:1 citrulline malate contains approximately 5.3 g L-Citrulline — if dosing pure citrulline base to match, the dose would be lower.
