Men's sexual health, explained simply.

Libido, testosterone, and performance rest on boring fundamentals, sleep, weight, blood sugar, and a few key nutrients. Here's the honest beginner version.

The biggest levers aren't in a bottle: good sleep, a healthy weight, regular movement, and stable blood sugar do more for testosterone and performance than any supplement. The items below help mainly by fixing real shortfalls.

The basics that actually matter

Foundations, not "boosters."

Vitamin D Moderate evidence

The "sunshine" vitamin, linked to healthy testosterone.

Correcting a deficiency may support hormone levels. Very common to be low, worth testing.

Zinc Moderate evidence

A mineral important for testosterone and fertility.

Helps when you're low. Not a "more is better" situation.

Magnesium Moderate evidence

A mineral for sleep, stress, and hormone balance.

Better sleep and lower stress quietly support libido and testosterone.

Omega-3 (fish oil) Moderate evidence

Healthy fats that support blood flow.

Erections are about circulation, heart-healthy habits and fats help.

Ashwagandha Emerging evidence

A herb traditionally used for stress and vitality.

Some studies suggest it may help stress and testosterone, but it needs caution (see below).
