Vitamin D3

One of the most impressive benefits of vitamin D3 is its ability to enhance immunity and protect against infection.

Not only can a deficiency in this important micronutrient slow wound healing and increase the risk of infection, but vitamin D3 is also integral to the function of immune cells in the body.

According to research, lower levels of serum vitamin D are actually associated with the a higher risk of recent respiratory tract infections, demonstrating just how crucial this vitamin is for immunity.

Some experts now even recommend that people who are deficient and at risk for certain illnesses take a high dose of vitamin D3 to quickly raise levels, followed by moderate doses (about 10,000 IU/day of vitamin D3 for a few weeks, followed by 5,000 IU/day).
