## Description

Helps Maintain Normal Bone and Tooth Formation

Vitamin D helps the body to regulate the transport of calcium from the digestive system through the bloodstream to bone. It also assists in the retention of calcium and phosphorus.

Nature's Way Vitamin D is 100% natural cholecalciferol. The dry form is specially formulated for easy absorption. It contains no artificial ingredients or preservatives.

Also consider a comprehensive daily multivitamin and multimineral supplement with vitamin D called MultiVit Rx, formulated by Ray Sahelian, M.D. We also carry highly popular products including Mind Power Rx and Eyesight Rx.

The recommended daily intake of vitamin D is 200 iu for adults younger than 50 years and 600 iu for those older than 70 years. Vitamin D supplementation is especially important in elderly persons because skin synthesis and absorption of vitamin D may be impaired.

This vitamin D product is free of common food allergens. It contains no yeast, milk, lactose, wheat, sugar or soy.

Vitamin D questions
Q. I understand there are 2 types of Vitamin D sold over the counter. Which is better"
 A. Supplemental vitamin D is available in 2 distinct forms: ergocalciferol (vitamin D2) and cholecalciferol (vitamin D3). Vitamin D3 has proven to be the more potent form of vitamin D in all primate species, including humans. Vitamin D3 can also be produced in the skin through exposure to sun. Subsequently, Vitamin D3 is metabolized by the liver and kidney to the biologically active form 1,25-dihydroxyvitamin D3.

Q. How much vitamin D should be ingested on a daily basis through diet or food?
 A. Much depends on your sun exposure, but for most people a dietary and/or supplemental intake of 400 to 800 units a day should be quite acceptable.
