L-citrulline DL-malate combines the amino acid L-citrulline with malic acid, typically in a 1:1 or 2:1 ratio. This compound is widely used in sports nutrition for its role in boosting nitric oxide production, improving ammonium excretion, and raising L-arginine and L-ornithine plasma levels.
For food and supplement manufacturers serving halal markets, sourcing L-citrulline DL-malate with proper halal certification is critical. The origin of the amino acid component determines whether the final product qualifies as halal.
Halal Certification for L-Citrulline DL-Malate
Yes, L-citrulline DL-malate is available with halal certification from multiple global suppliers. IFANCA-certified manufacturers like Shine Star (Hubei) Biological Engineering produce both L-citrulline DL-malate 1:1 and 2:1 ratios under halal supervision, with certification continuously maintained since 2012.
The halal concern with amino acids often centers on the raw material source. L-citrulline can historically be derived from animal sources, including duck feathers through chemical hydrolysis. However, when produced under halal-certified conditions with proper Islamic supervision, duck feather-derived L-citrulline is considered permissible by major certification bodies.
Specifications and Quality Standards
Food-grade halal L-citrulline DL-malate (1:1) should meet strict quality parameters. Typical specifications include residue on ignition of not more than 0.1%, total plate counts below 1,000 CFU/g, and yeast and mold counts under 100 CFU/g.
The product should be stored in well-closed containers in a cool, dry, and ventilated warehouse away from moisture. Always request a current certificate of analysis alongside the halal certificate when evaluating a new supplier.
Sports Nutrition and Functional Applications
L-citrulline DL-malate is primarily used as a sports nutritional supplement. The malate component contributes to the citric acid cycle, potentially supporting aerobic energy production during exercise.
Supplementing with L-citrulline DL-malate increases both L-ornithine and L-arginine plasma content. This dual mechanism supports both ammonia clearance and nitric oxide generation, making it a popular pre-workout ingredient in halal supplement lines.
