Vitamin D, provided by Douglas Laboratories, contains 5,000 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 and
inflammatory support. †
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 5000 IU may be a useful dietary supplement for those individuals wishing to support general health
or whose requirements for vitamin D cannot be met by lower potency products.
Adults take one tablet daily or as directed by physician.
No adverse side effects have been reported.
Note: People consuming more than 2,000 IU per day should have their vitamin D blood levels monitored by a healthcare professional.
Store in a cool, dry place, away from direct light. Keep out of reach of children.
