Italian urologists gave men one thing for a month. Half of them went from mild ED to normal hardness.
The one thing
Ask your doctor about taking 1.5 grams of L-citrulline a day.
L-citrulline is an amino acid your body turns into arginine, which it uses to make nitric oxide. Nitric oxide relaxes the arteries in the penis so they can fill with blood.
Do it today
- Talk to your doctor first, especially if you take blood pressure or ED medicine.
- If you try it, the study dose was 1.5 grams a day, taken for one month.
- Track your erections before and after, so you know if it helps you. The men in the study had mild ED only.
What the study found
On placebo, 2 of 24 men (8.3%) went from a hardness score of 3 (mild ED) to 4 (normal). On L-citrulline, 12 of 24 men (50%) did. Sex went from 1.37 times a month at the start to 2.3 times a month by the end of the L-citrulline month. No one had side effects.
- Who
- 24 men in Italy with mild erectile dysfunction, average age 56.
- Type of study
- Single-blind study: one month of placebo, then one month of 1.5 grams a day of L-citrulline.
- Keep in mind
- Very small and short. Every man took the placebo first, so some of the change may come from time or expectation. The authors say it works less well than ED pills.
Check first: Ask a doctor first if you take blood pressure medicine, nitrates for chest pain, or ED pills, since all of these also widen blood vessels.
