L-citrulline

L-Citrulline (CAS 372-75-8 ) is a non-essential amino acid naturally occurring in watermelon and produced endogenously in the urea cycle. In commercial applications, it functions as a precursor to L-arginine.

It supports nitric oxide pathway activity that underpins its use across sports nutrition, pharmaceutical, and personal care formulations. In sports nutrition, it is a primary active ingredient in pre-workout powders.

These capsules target exercise performance and muscle recovery. Pharmaceutical manufacturers use it as an active or supporting ingredient in formulations addressing urea cycle disorders and cardiovascular-related indications.

In functional food and beverage development, it is incorporated into fortified drinks and nutritional bars where amino acid enrichment is a label claim. Personal care formulators include it in topical products.

It is used for its moisture-retention contribution and its role in supporting skin barrier function. This product is supplied as a white crystalline powder for various industrial and commercial applications.

Food-grade and USP -grade specifications are the most commonly traded forms. Food-grade material meets FCC standards for use in ingestible products and dietary supplement manufacturing.

Bulk quantities are available for industrial formulation. Pharmaceutical-grade material is subject to tighter purity and testing requirements to ensure compliance with global regulatory standards for safety.
