Life Extension Vitamin D3 is a special purpose, non-GMO, high potency formula that supports a healthy immune system and helps maintain healthy bones and teeth.
You can synthesize Vitamin D in the skin during exposure to ultraviolet-B (UVB) radiation from sunlight. However, weather conditions and the growing use of sun block may inhibit the ability of the body to produce optimal vitamin D levels and result in Vitamin D deficiency.This is why there may be value in taking a daily vitamin D supplement.
Vitamin D helps with calcium absorption in your small intestines and supports calcium reabsorption in your kidneys. Vitamin D may also have a significant impact on immune health, as it may also play a role in regulating healthy cell division and differentiation.
Currently, the recommended daily allowance is only 600 IU.
However, some nutritional scientists are calling for that level to be increased to 1,000 IU per day and higher.
For those who need to take higher doses of Vitamin D3 and are under a physicians supervision, Life Extension has made available this 5,000 IU Vitamin D3 supplement.
Anyone taking this 5,000 IU Vitamin D3 supplement should take regular CBC/chemistry blood tests.
