CITRULLINE: Naturally Improve Blood Flow and Endurance


(Improve Circulation)

 High Quality Naturally Occurring Amino Acid (found in watermelon, onions, liver) Scientifically Shown to Increase Blood Flow and Reduce Blood Pressure.

Proven Nutrition’s CITRULLINE contains ultra-high purity L-Citrulline Malate that improves absorption and efficacy. When used daily, the active ingredient in CITRULLINE has been scientifically shown to:

  • Improve Circulation Increase Blood flow and Lower Blood Pressure
  • Reduces Fatigue
  • Improve Physical Endurance
  • Improve Muscle Recovery and Reduce Muscle Soreness
  • Alleviate Symptoms of Mild Erectile Dysfunction

Great Add-Ons to CITRULLINE:

  • CORE: All-Natural Drink Mix for Every-Day Health and Refreshment
  • BETA: For added Exercise Endurance and Recovery
  • D-AA: All Natural Nutritional Support for Male Hormones
  • HEAL: Maintain Healthy Joints and Reduce Inflammation
  • CREA-HCL: Ultra-High Purity Creatine Without Bloating

L-Citrulline supplementation has been scientifically shown to benefit cardiovascular health, exercise endurance and muscle recovery by the follow mechanisms:

  • L-Citrulline is converted to L-Arginine by the kidneys.
    • L-Arginine is then utilized by the body to produce nitric oxide.
    • Nitric Oxide relaxes smooth muscles around the blood vessels which increases blood flow.
  • Increased blood flow produced by L-Citrulline supplementation has several health benefits.
    • Lower blood pressure.
    • Increased nutrient and oxygen delivery to muscles which improves endurance and reduces fatigue.
    • Improves the removal of toxins in the muscles after exercise which improves recovery and reduces muscle soreness.
    • Improves the quality of erections in cases of mild-erectile dysfunction.

L-Citrulline supplementation may be particularly important for those with cardiovascular conditions who want to maintain physical activity and reduce blood pressure.
