What Vitamin Does a Man With ED Need?

From Sexual Health For Men Dr. Anne Truong

The supplement aisle is full of “ED cures” with exotic names and zero science behind them.

This episode cuts through the noise and focuses on the one vitamin with an overwhelming body of clinical evidence tied to erectile dysfunction. You’ll learn why low levels are linked to a 30% higher risk of ED and how deficiency can make your ED pills less effective. Most importantly, you’ll walk away with a simple four-test blood work checklist so you can stop guessing and start fixing the root cause.

Tune in to the full audio episode now and find out what your blood work could be telling you about your erections.

Key Takeaways

Vitamin D3 has the strongest clinical evidence of any vitamin linked to ED, especially vascular ED.
Levels below 20 ng/mL are independently tied to a 30% higher risk of ED, regardless of age, blood pressure, or testosterone.
Low vitamin D drains nitric oxide, damages blood vessels, and may promote penile fibrosis that weakens your response to ED pills.
Vitamin D helps mainly if you’re deficient, so test before you supplement.
Low folate and B12 raise homocysteine, which damages the arteries your erections depend on.
Skip megadose antioxidants and follow a Mediterranean diet instead.
Get four labs checked: 25-hydroxy vitamin D, folate, B12, and testosterone.
