Vitamin D helps keeps bones and teeth healthy, and your immune system strong by promoting cell regrowth.
Vitamin D also has multiple important roles in skin physiology, including the formation of new blood vessels and wound healing.
A lack of vitamin D can lead to bone deformities such as rickets, and bone pain generally.
Humans have the ability to synthesize vitamin D via UV exposure. Lack of UV exposure is therefore implicated in many cases of reduced vitamin D levels, particularly in those with darker skin types. Oral supplementation of vitamin D has been used for many years and is recognized to be of benefit in deficiency.
Here are three ways to increase your levels of Vitamin D;
1. UV Exposure
As described above, your body can absorb a certain type of Vitamin D which travels to the liver to be turned into a type of Vitamin D that your body can use. You need around 15 minutes of exposure to sunlight for this process to take place. The more skin exposed, the more effective the process.
Vitamin D can be found in oily fish, egg yolks, liver, red meat, and fortified foodstuffs.
Due to the lack of sunlight in some parts of the world, Vitamin D supplements may be required. In the UK, we may not get enough Vitamin D between October and March. The NHS advises a supplement of 10mcg per day.
