Vitamin D is an essential vitamin that’s required for the proper function of numerous systems in the body. Unlike other vitamins, vitamin D functions as a hormone that every single cell in your body has a receptor for.

Your body has the ability to synthesize vitamin D from cholesterol when your skin is exposed to direct sunlight. Vitamin D is also found in certain foods, including fatty fish and fortified dairy products.

Vitamin D deficiencies are very common as it’s difficult to meet your daily requirements from diet alone.  It’s estimated that nearly 1 billion people worldwide have low levels of serum (blood) vitamin D.

Vitagenis’s Vitamin D supplements are formulated with vitamin D3 (cholecalciferol). This form is identical to the one we create in the body. Cholecalciferol is shown to be three times as potent as vitamin D2.

Vitamin D deficiencies can lead to muscle weakness, brain “fog”, fatigue, brittle bones, and bone pain. If left untreated, a vitamin D deficiency can lead to an increased risk of cardiovascular disease, cancer, osteoporosis, and cognitive impairment.

For pregnant women, a vitamin D deficiency can lead to low birth weights and pre-eclampsia. For men, low levels of vitamin D can lead to erectile dysfunction.

A primary function of vitamin D in the body is calcium homeostasis. It is essential for skeletal development and bone mineralization. Thus, a vitamin D deficiency in adults can lead to osteoporosis and osteopenia.

If you think you may have a vitamin D deficiency, it’s important that you speak to your doctor and get your blood levels measured.
