About Vitamin D

Vitamin D is one of the few essential nutrients that is not abundant in a wide variety of foods. The foods that do contain a decent amount of vitamin D include mackerel, salmon, tuna and sardines. One serving of each delivers about 200 IU per serving, which is still well below the recommended amount for optimal health. Some fortified foods contain vitamin D, but it is usually in a form that is less easily absorbed, vitamin D2. Vitamin D3 has been shown in studies to be as much as three times as effective as vitamin D2 in maintaining and raising blood levels of vitamin D. D3 is more expensive to produce, but research shows that it is clearly superior to vitamin D2, which is why Premier Research Labs only uses vitamin D3 in its D3 Serum.

Vitamin D is also made from the body after it is exposed to sunlight, which is why it is often called the sunlight vitamin; however, many people are lacking in vitamin D because of limited sun exposure. Fear of harmful UV rays keeps many people from exposing their skin to the sun without protection. 

Benefits

Population surveys have shown that groups with greater sunlight exposure have better immune function that those who have limited sunlight exposure. This is likely because vitamin D3 receptors are known to exist on most immune cells and play a role in maintaining healthy immune cell differentiation, integration and maturity. Vitamin D3 is also known to play a vital role in 

  • calcium absorption
  • stronger bones.
