L-Citrulline DL-Malate 1:1

L-Citrulline DL-Malate 1:1 (CAS 54940-97-5), also known as Citrulline Malate or by the trade name Stimol, is a 1:1 salt formed from the amino acid L-Citrulline and DL-Malic acid. It carries no assigned E-code. The compound is used across food, nutrition, and pharmaceutical applications.

In sports nutrition and functional food formulations, Citrulline Malate supports nitric oxide metabolism by serving as a precursor in the urea cycle, which influences ammonia clearance and blood flow. The malate component contributes acidulant and flavour-modifying properties, making it suitable for use in effervescent tablets, powdered drink mixes, and oral pharmaceutical preparations.

The compound is available in pharmaceutical and food-grade forms, with quality benchmarks referenced against FCC and Ph.Eur. monographs for constituent materials. It is subject to REACH registration requirements for EU supply. Packaging is typically offered in multi-kilogram bags or drums suited to industrial procurement volumes.
