About NOW – L-Leucine Powder (255 g)
NOW L-Leucine Powder delivers 5,000 mg of pure, instantized L-Leucine per serving — one of the essential branched-chain amino acids (BCAAs) that the body cannot synthesise on its own and must obtain through diet or supplementation. L-Leucine plays a key role in protein synthesis and is a popular choice among athletes, fitness enthusiasts, and those looking to support their daily protein intake conveniently.
This formula uses an instantized, Non-GMO form of L-Leucine, meaning the powder disperses readily in water or other beverages without excessive clumping. With approximately 51 servings per container, the 255 g tub offers a practical and cost-effective supply. The only additional ingredient is a small amount of Non-GMO Sunflower Lecithin (less than 5%), used to enhance mixability.
Produced in a GMP-certified facility and free from a wide range of common allergens, NOW L-Leucine Powder is suitable for vegans and vegetarians and fits seamlessly into gluten-free and lactose-free lifestyles. It can be mixed into water, shakes, or any beverage of your choice for straightforward daily use.
