Vitamin D: The Sunshine Vitamin

By Dr Kelly

January 28, 2018

Vitamin D, also known as the "sunshine vitamin", is a fat-soluble vitamin that is essential for overall health and well-being. It plays a crucial role in bone health, immune function, and various other physiological processes.

One of the primary functions of vitamin D is to help the body absorb calcium and maintain bone health. Without enough vitamin D, the body cannot absorb calcium properly, which can lead to weakened bones and an increased risk of fractures. This is why vitamin D is often recommended as a supplement for people at risk of osteoporosis or who have low bone density.

Vitamin D also plays an important role in the immune system, helping to regulate the activity of immune cells and reduce inflammation. Studies have shown that low levels of vitamin D may be linked to an increased risk of autoimmune diseases, such as multiple sclerosis and rheumatoid arthritis.

In addition, vitamin D may have other health benefits, such as reducing the risk of certain cancers, improving heart health, and supporting healthy brain function. However, more research is needed to fully understand these potential benefits.

The primary source of vitamin D is sunlight, as the skin can produce vitamin D when exposed to sunlight. However, many people do not get enough vitamin D from sun exposure alone, particularly during the winter months or in areas with less sunlight. Vitamin D can also be obtained through dietary sources, such as fatty fish, egg yolks, and fortified foods like milk and cereal.

Recommended daily intake of vitamin D varies by age, gender, and other factors, but generally ranges from 400-800 IU per day for most adults. However, some people may need higher doses of vitamin D, particularly if they have a deficiency or certain health conditions.

It's important to talk to your healthcare provider before starting any new supplement regimen, including vitamin D, as excessive intake of vitamin D can be toxic and cause serious health problems.
