Based on an ever-growing body of research, an increase in vitamin D has been shown to be beneficial for a tremendous variety of health issues, far too many to list here. One recent study (of many) shows that the dose required to achieve a healthy blood level of vitamin D is 1,000 – 3,000 IU per day in the absence of sun exposure. 
Here are but a few of the health disorders that adequate amounts of vitamin D help protect against:
· Various forms of cancer including breast, prostate, and colon cancer
· Heart Disease
· Pain and Muscle Aches
· Insulin Resistance
· Decreased immunity and lowered resistance to influenza and viruses
· Seasonal Affective Disorder (SAD)
While all are important, it’s the latter three that come into play the most during the winter months, a time when sun exposure for many of us is minimal. Vitamin D supplements are a very inexpensive way to ensure that you’re obtaining enough of this multi-beneficial vitamin. Therefore, we suggest 1000 – 3000 IU of vitamin D3 (cholecalciferol) daily, in divided doses. The cholecalciferol form of vitamin D is what the body manufactures via sunlight, and the form most efficient for the body’s needs.
NOTE: Premium Insurance Caps contains 500 IU of vitamin D3 (cholecalciferol) per 7-capsule dose.
