L-Citruline - OptimalVitaleMD.com L-Citruline

L-citrulline is a natural amino acid found in watermelons, but important to humans! Formed from L-arginine, it is also converted back to L-arginine! Arginine is a major source of nitric oxide (NO) production. Note that this is not nitrous oxide (N2O), the so-called laughing gas dentists use. Nitric oxide is called a vasodilator, meaning it dilates blood vessels, increasing blood flow. This helps in:

Think of L-citrulline as a delivery system for nitric oxide.
Benefits of nitric oxide:

Nitric oxide may improve the following:
  • Brain - Increased blood flow and thus more oxygen to the brain can improve mood, memory, and mental acuity.
  • Heart - Dilated blood vessels lead to reduced blood pressure and stress on the heart. Nitric oxide also inhibits platelet aggregation (blood clots) and artery-clogging plaques (atherosclerosis).
  • Immune System – Nitric oxide reduces oxidative stress and inflammation, two key elements of many degenerative diseases.
  • Muscles - builds lean muscle mass and improves athletic performance
  • Erectile Dysfunction (ED) and Sexual Health – Nitric oxide dilates blood vessels. These include blood vessels in the penis. Most cases of erectile dysfunction (ED) arise from vascular problems, so dilation of penile blood vessels can often help. In fact, prescription ED medications such as Viagra and Cialis work because they enhance nitric oxide signaling, relaxing penile blood vessels and improving blood flow to the region. Because they work via similar mechanisms, you should not take L-Arginine with erectile dysfunction medications. Nitric oxide also may help your body make sperm and improve sperm motility.

Why use L-citrulline and not just L-arginine? Look at the scientific evidence!
1) According to a recent clinical study, administering citrulline actually results in higher blood levels of L-arginine than giving L-arginine on its own1.
2) L-Citrulline PLUS L-arginine helped prevent diet-induced atherosclerosis in rabbits2.
3) Human trials indicate oral L-citrulline improves erection hardness in men with mild erectile dysfunction (ED)3.
