Vitamin D is essential for your body’s growth and development. It’s believed that a lack of it can lead to fatigue, bone weakness, and a weakened immune system. Here’s what you should know about vitamin D deficiency:

The Importance of Vitamin D

According to the National Institute of Health, vitamin D is needed for your body’s absorption of calcium and phosphorus, which makes bones stronger and reduces your risk of fractures. It also blocks the release of parathyroid hormone. Without it, the hormone reabsorbs bone tissue, leading to thin and brittle bones. A healthy balance of vitamin D can also help support your immune system, allowing for a strong defense against a variety of disease and bone disorders.

The best way to identify low vitamin D levels is through yearly blood tests.

Some medical conditions can lead to a problem with vitamin D absorption, making you more susceptible to a vitamin D shortage, such as:

• Kidney and Liver Disease

• Obesity

• Recent Gastric Bypass Surgery

• Celiacs Disease

Sources of Vitamin D

Sunlight: The easiest way to increase your vitamin D is through sun exposure. When exposed to UV light, your skin makes vitamin D — this is why a deficiency is more common in the cloudy, cold, and winter months.

Food Sources: A well-balanced diet can also help increase your absorption of vitamins, especially vitamin D. Fatty fish, dairy, and mushrooms are some of the best sources.

Supplements: Vitamin D supplements can help you stay at a healthy level. Depending on your age, that daily recommended dose can change, so it’s vital to discuss with your doctor supplement options. It is possible to have too much, vitamin D so discussing a supplement plan is key.
