If you are magnesium deficient, you cannot utilize the vitamin D in your body. It remains trapped in storage, and unavailable in your bloodstream. Approximately 50 percent of Americans are magnesium deficient. That means they’re missing out on the amazing health benefits of vitamin D.

This finding comes from a review published in The Journal of the American Osteopathic Association. According to study co-author Mohammed S. Razzaque, MBBS, PhD, a professor of pathology at Lake Erie College of Osteopathic Medicine, "People are taking Vitamin D supplements but don't realize how it gets metabolized. Without magnesium, Vitamin D is not really useful or safe”.

Taking Vitamin D supplements can raise a person's blood calcium and phosphate levels even if they remain Vitamin D deficient. The risk is, people can suffer from vascular calcification if their magnesium levels aren't high enough to prevent this occurring. Patients with sufficient blood magnesium levels require less Vitamin D supplementation to achieve optimum Vitamin D levels. Magnesium has other benefits; it reduces osteoporosis, helping to mitigate the risk of low bone density that can occur due to low levels of Vitamin D. Deficiency of vitamin D or magnesium is associated with numerous health problems, including skeletal deformities, cardiovascular diseases, and insulin resistance.

It’s quite difficult to get sufficient magnesium. The majority of my patients are deficient. Many factors deplete your body of this amazing mineral. A large number of medications reduce your magnesium level; the biggest offenders are antacids, acid blockers, hormonal contraception and diuretics. Taking a magnesium supplement should help; however, a lot of poor quality supplements are hard on the stomach and can cause a digestive upset. Magnesium Complete tablets and Magnesium Ultra Potent powder are gentle on the digestive system.

It is also important to remember that stress and anxiety deplete your body of magnesium, as the stress hormone cortisol causes urinary loss of this mineral. Digestive problems such as celiac disease, irritable bowel syndrome and leaky gut reduce magnesium absorption, therefore a supplement is essential in those cases.
