What are the risks associated with vitamin D deficiency?

Vitamin D deficiency can cause a range of health issues, both in the short-term or long-term. It is one of the most common deficiencies across the world, being particularly prevalent in countries that receive less sunlight during the year.

There are several risks associated with chronic vitamin D deficiency, including the following.

Bone health disorders

Vitamin D is essential for the absorption of calcium and phosphorus in the intestines and the usage of these minerals in the bone formation process. A deficiency in vitamin D can lead to a weakening of the bones, increasing the risk of conditions like osteopenia and osteoporosis in adults.

Muscle weakness

Vitamin D is necessary for muscle function, particularly as it promotes increased calcium absorption, the key mineral in muscle contraction. A deficiency in vitamin D may contribute to muscle weakness and pain, as well as decreased mobility and an increased risk of falls, especially in the elderly population.

Weak immunity

Vitamin D plays a key role in immune function, and a lack of this vital nutrient can lead to impaired immunity. In turn, you may become more susceptible to infections and illnesses, and it may take you longer to recover when you do fall ill.

In particular, low levels of serum vitamin D have been associated with a higher risk of respiratory infections, which includes the common cold or influenza virus.
