Vitamin D for Menopause

What it is

Vitamin D is technically a hormone, not just a vitamin — and it affects nearly every system in your body. Your skin makes it from sunlight, but most women over 40 don't produce enough, especially in northern climates or if they spend most of their time indoors. During menopause, adequate vitamin D becomes even more critical.

How it helps with menopause

Vitamin D affects energy, mood, bone health, and immune function — all of which are challenged during menopause. For bones, it's essential: vitamin D helps your body absorb calcium, and bone density drops fastest in the years around menopause. For mood, low vitamin D is linked to depression and low energy. For immune health, it supports the body's defense system, which can become less efficient during the menopause transition. Many women who supplement report noticeable improvements in energy and mood within 4–6 weeks.

Dosage & timing

1,000–4,000 IU daily, depending on your current levels (a blood test can help determine the right dose). Take it with a meal that contains fat, since vitamin D is fat-soluble. Pair it with vitamin K2 (100–200mcg MK-7) — K2 ensures the calcium that vitamin D helps absorb goes into your bones, not your arteries.

What to look for

Vitamin D3 (cholecalciferol) is the preferred form — it's the same form your body produces from sunlight and is better utilized than D2. Many good supplements combine D3 with K2 in a single capsule. Look for a reputable brand with third-party testing. If you can, get your levels tested before supplementing so you know your baseline.
