NOW Foods L-Citrulline 750 mg provides a non-essential amino acid in convenient vegetable capsules. Each capsule supplies 750 mg of L-Citrulline, while the recommended two-capsule serving delivers 1,500 mg. This formula is designed to support protein metabolism, normal urea-cycle function and healthy immune system activity.

L-Citrulline is an important intermediate in the urea cycle. Working alongside other amino acids, it helps the body process ammonia, a natural byproduct of protein metabolism. Citrulline also contributes to normal tissue-maintenance processes and helps maintain healthy immune function as part of a balanced lifestyle.

Each bottle contains 90 vegetable capsules, providing 45 servings and flexible daily use between meals. The formula is vegan, vegetarian, non-GMO, halal, kosher, dairy-free, egg-free, soy-free, nut-free and made without gluten. NOW Foods makes and quality-tests this supplement in the USA with globally sourced ingredients under GMP-certified standards. It is a quality-focused choice for adults seeking straightforward L-Citrulline supplementation and routine-friendly amino acid metabolism support.
