Episode notes
Placebo Drives Many Sexual Supplement Claims
- Expect a large placebo effect with sexual-function supplements; perceived benefits are common.
- Randomized controlled trials are necessary to separate true effects from placebo.
Use L-Citrulline For Mild ED
- Try L-citrulline 1500 mg daily to support nitric oxide and improve mild-to-moderate erections.
- Use it as adjunct to PDE5 inhibitors if needed, but don't expect it to fix severe ED.
Hydrate And Time Abstinence For Bigger Volume
- Do not rely on supplements to increase semen volume; instead, drink more fluids and abstain 2–3 days before ejaculating.
- Check medications and diabetes as causes of low apparent volume like retrograde ejaculation.
