Vitamin D can be derived naturally from the sun. For the average person, spending as much at 10 to 20 minutes in the sun at least three times a week will fulfill their vitamin D requirements. Keep in mind that people with darker skin need more sun exposure because the melanin in the skin tends to block vitamin D absorption. In addition, those who live in an area which is north of Columbia, South Carolina’s latitude may not be exposed to enough sun during the winter months and may require supplementation.
Rutgers University, with campuses in New Brunswick and Newark, New Jersey is conducting an ongoing study in regards to how supplementation of vitamin D can halt and/or decrease bone loss in post-menopausal women who are dieting. Furthermore, recent studies have shown that keeping sufficient levels of vitamin D may aid in weight loss.
Even though vitamin D supplements may keep the body healthy and may be natural, more does not always mean better. An overdose of vitamin D may cause kidney damage, high blood pressure and heart arrhythmia. If you suspect that you may have a vitamin D deficiency, check with your doctor or other medical professional to get an official diagnosis.
