L-Citrulline- 750mg

L-Citrulline is a substance called a non-essential amino acid. Your kidneys change L-Citrulline into another amino acid called L-arginine and a chemical called nitric oxide. These compounds are important to your heart and blood vessel health, and nitric oxide improves circulation which is the secret to hard, firm, healthy erections.

You might be wondering why AFFIRM® has L-citrulline rather than L-arginine. As it turns out, L-Arginine is broken down by the intestines and does not make it into the blood stream intact. Instead, L-Citrulline goes into the kidneys where it is rapidly converted into L-Arginine.

That’s why L-Citrulline is the better choice for men looking to produce strong, hard erections. Scientific studies have proven L-Citrulline supplementation increases blood levels of L-Arginine more effectively than supplementation of L-arginine alone. L-Citrulline can actually reverse blood vessel lining dysfunctions by activating another very important compound for growing blood vessels called vascular endothelial growth factor (VEGF).

VEGF repairs and improves the function of the blood vessels throughout the body, including within the corpus cavernosum, the sponge-like regions of erectile tissue that contain most of the blood in the penis during penile erection.

It has been scientifically demonstrated that L-Citrulline improves erectile hardness in men with mild erectile dysfunction, and improved penile blood pressures and Nitric Oxide levels in rat experimental models.

L-Citrulline is safe with no reported side effects. However, the supplement may affect the way certain drugs work in your body. Do not take this supplement if you are taking nitrates for heart disease. Be aware that L-Citrulline in combination with ED drugs such as Cialis, Levitra, or Viagra, may lower your blood pressure.
