Citrulline Malate 90 Caps by BioTech USA is an advanced formula that combines L-citrulline and malic acid in a 1:1 ratio. This supplement is popular among endurance and strength athletes, providing 2200 mg of citrulline malate per 2-capsule dose. L-citrulline is an amino acid whose production can be inadequate during intense physical effort. When combined with malic acid, it forms citrulline malate, a precursor to L-arginine and L-ornithine. The capsules have a neutral taste and are easy to dose, making this product a convenient option before intense physical activity. It is recommended to store in a cool, dry place, away from direct sunlight, and to close the container tightly after each use.
