  • Used as a workout supplement
  • Improves athletic performance in high-intensity anaerobic exercise with short rest periods
  • Provides a precursor for L-arginine production
  • Supports muscle protein synthesis

Natural Factors L-Citrulline is a free-form amino acid supplement used to support healthy nitric oxide levels in the bloodstream. By serving as a precursor to the amino acid L-arginine, L-citrulline helps the body produce nitric oxide more efficiently. Nitric oxide has many critical functions in the body through its role in helping blood vessels relax and expand.

L-citrulline is a popular workout supplement for athletes, fitness enthusiasts, and bodybuilders. It supports increased athletic performance during intense anaerobic exercise with short rest periods, such as high-intensity interval training (HIIT) and weightlifting. L-citrulline is also used by men to improve symptoms of erectile dysfunction through the dilation of blood vessels and promoting healthy blood flow.

The body's ability to generate nitric oxide decreases in older age, which can affect arterial health and function. Supplementing with L-citrulline is a convenient way to round out your amino acid intake, support L-arginine production, and help improve nitric oxide synthesis. This high-potency supplement contains 1000 mg of L-citrulline per tablet, taken three times per day to maintain a steady intake. It is made naturally through bacterial fermentation and is a non-GMO, vegan formula.

Recommended adult dose: 3 tablets 1 time daily or as directed by a health care practitioner.
