ED supplements are widely marketed. Most have weaker evidence than prescription medications (sildenafil, tadalafil). Best supplements for ed may help mild cases or as adjuncts. For significant ED, evaluate underlying causes (cardiovascular, hormonal) and consider prescription treatment. Always discuss with healthcare provider.
Supplements with some evidence
L-citrulline: Increases nitric oxide. Some evidence for mild ED. 1.5-3 g daily.
L-arginine: Similar mechanism. Less effective than L-citrulline due to absorption.
Ginseng (Korean Red): Some evidence for ED. 600-1000 mg daily.
DHEA: Some evidence in older men with low DHEA. Specialized use.
Limited evidence
- Most “male enhancement” blends
- Yohimbe (potential cardiovascular risks)
- Maca root
- Most exotic herb blends
Counterfeit supplement warning
Many “natural” ED supplements have been found to contain undisclosed prescription drugs (often sildenafil) — making them not “natural” and creating drug interaction risks.
Underlying causes to address
ED is often a marker of underlying conditions:
- Cardiovascular disease
- Diabetes
- Low testosterone
- Sleep apnea
- Depression
- Medication side effects
ED warrants medical evaluation, particularly in men under 60.
Frequently Asked Questions

Modest effect for mild ED. Not as effective as PDE5 inhibitors.
Should I see a doctor for ED?
Yes, especially if persistent. May indicate underlying conditions.
Can supplements be combined with Viagra?

The bottom line on ED supplements
L-citrulline and ginseng have modest evidence. Prescription PDE5 inhibitors more effective. Evaluate underlying causes. Be cautious of supplement quality.
