How does it work?
L-Citrulline is an amino acid that converts to L-Arginine in the body, supporting nitric oxide production. Increased nitric oxide promotes vascular dilation, improving blood flow, oxygen delivery, and muscle performance.*
What fitness benefits does L-Citrulline support?
L-Citrulline supports nitric oxide metabolism, healthy vascular function, and muscle protein synthesis.* It may help alleviate muscle soreness after exercise and support endurance and energy during training.*
When should I take it and how do I use it?
Mix 1 level scoop with 8 oz. of water or a beverage of your choice before a workout, or as recommended by a nutritionally informed physician. Do not use in conjunction with vasodilating medications.
How much per serving?
Each serving is 1 level scoop (~3 grams / 3,000mg) of pure L-Citrulline. The 200g container provides approximately 66 servings. There are no added flavors, colors, or preservatives — just one ingredient.
Is this product vegan, non-GMO, and gluten free?
