Vitamin D 25 mcg (1000 IU)

Vitamin D 25 mcg (1000 IU), provided by Douglas Laboratories, contains 1,000 I.U. of natural vitamin D3 per tablet.


Vitamin D, also known as the “sunshine vitamin” is an essential vitamin that plays many important roles in the proper functioning of the body. Though classified as a vitamin, vitamin D is actually a key regulatory hormone for calcium and bone metabolism.

Adequate vitamin D status is essential for ensuring normal calcium absorption and maintenance of healthy plasma calcium levels. Besides bone support, vitamin D has many other roles in the body, including modulation of cell growth, neuromuscular and immune function.

Numerous scientists now feel that supplementation with vitamin D at levels greater than previously thought necessary is critical to helping maintain healthy bone remodeling and healthy vitamin D plasma levels.


Vitamin D may be a useful dietary supplement for those who wish to increase their daily D intake.
