Vitamin D plays a vital role in maintaining strong bones, supporting the immune system, and helping muscles and nerves function properly. Unfortunately, vitamin D deficiency is common among women, especially those who spend little time outdoors, have darker skin, are pregnant, or are over the age of 50.
Because the symptoms often develop gradually, many women don’t realize they have a deficiency until it begins affecting their daily life. Identifying the warning signs early can help prevent long-term complications and improve overall health.

What Is Vitamin D?
Vitamin D is a fat-soluble vitamin that helps the body absorb calcium and phosphorus. It supports:

Your body produces vitamin D when your skin is exposed to sunlight, and it can also be obtained from certain foods and supplements.

Some women have no symptoms until the deficiency becomes severe.
