L-citrulline is an amino acid which has been investigated for having potential human health benefits. It is of particular interest for its impacts on smooth muscle, skeletal muscle, and the cardiovascular systems. This project is the production of a liquid supplement that incorporates a L-citrulline formula in a way that will be suitable for consumers. Trial formulations were performed in food labs at Cornell University. The purpose was to make a fluid that has permissible hedonic properties and is well suited to abide by FDA regulation of dietary supplements. Hundreds of combinations were tried and tested for pH, temperature manipulation, and stability. The resulting product is one that mimics the flavor profile of lemonade, possesses the bioavailability of amino acids found in watermelon, and L-citrulline levels that are enhanced in comparison to anything found in nature.
