Your Body Loves & Needs Vitamin D

Vitamin D is necessary for the regulation of the minerals calcium and phosphorus found in the body. It also plays a vital role in maintaining proper bone structure.

Exposure of the hands, face, arms, and legs to sunlight two to three times a week is all the body needs to manufacture sufficient vitamin D.

Regardless, vitamin D deficiency is more common than you would guess. Deficiency occurs even in sunny locations simply due to people staying indoors most of the day or by using too strong of a sun blocking screen.

Another cause of low levels of D even when taking significant amounts of vitamin D may be insufficient vitamin C. It is the critical factor to both prevent and reverse osteoporosis

Low vitamin D is strongly associated with Metabolic Syndrome but if elevated fasting insulin is causing the problem taking vitamin D won't fix it.

You make as much D as you will make just prior to pinkness which might be 7 minutes in very light skin and as much as 120 minutes in very dark skin, therefore sunning longer will not produce more.

Supplement companies are selling vitamin D in doses from 500 IU to as much as 50,000 IU. Supplement companies periodically send newsletters continuing to report the benefits of vitamin D and harmful effects of having too little D.

Some people need more D, from sunlight and/or supplements. Some people don't. Some people need more than other people because of many and varied reasons.

Having enough D simply makes life better.


UV-B is the only band of light producing vitamin D and it is blocked by sunscreen.

Low D needs to be diagnosed and corrected. Reasonably priced testing is available in most parts of the developed world.

We all need sunlight and/or vitamin D. Clinical studies demonstrate our ability to produce/absorb/utilize sunlight and vitamin D is genetically variable.

Getting enough vitamin D, from sunlight or supplements, is important to health and longevity but too much supplemental D or sunlight can be disease producing. Too much, too little is the only way to know how much D you have and how much sunlight or D you need to maintain D sufficiency is to test.
