Women's sexual & hormonal health, explained simply.

Libido, cycle, and hormonal balance shift across life stages. A few well-chosen nutrients support the foundations, here's the beginner version.

Energy, mood, and libido are tightly linked to iron, thyroid, sleep, and stress. Low energy often traces back to a fixable nutrient gap rather than anything mysterious. The items below help most when they're correcting a genuine shortfall.

The basics that actually matter

Foundations first.

Iron / ferritin Moderate evidence

Iron stored in the body, often low with heavy periods.

Low iron drives fatigue and low libido. Only supplement if a blood test confirms it.

Vitamin D Moderate evidence

The "sunshine" vitamin, tied to mood and hormones.

Deficiency is common and affects energy and wellbeing. Easy to test and correct.

Magnesium Moderate evidence

A calming mineral for PMS, cramps, and sleep.

Many women find it eases period symptoms and improves rest.

Omega-3 (fish oil) Moderate evidence

Healthy fats for mood and inflammation.

May help mood balance and period-related discomfort.

Folate Strong evidence (if planning pregnancy)

A B-vitamin essential before and in early pregnancy.

If you're planning a pregnancy, folate is one of the few supplements with clear, strong evidence, start it early.
