If you’re looking to get more vitamin D in your diet, take it with a side of magnesium.
That mineral appears to help regulate levels of vitamin D, which in turn manages the levels of other minerals such as calcium and phosphorus. It also improves bone strength and possibly reduces the risk of cardiovascular disease and cancerResearchers at the Vanderbilt-Ingram Cancer Center in Tennessee say that magnesium raises levels of vitamin D in people who need more of that substance and lowers levels among those who have an excess amount of the vitamin in their system.
The researchers reached their conclusions after conducting a randomized clinical trial involving 250 people considered at risk of colorectal cancer.The study, published in the December 2018 issue of the American Journal of Clinical Nutrition, was the first direct evidence that magnesium plays a role in vitamin D regulation.
A previous study from the same group of researchers found an association between low magnesium levels and low vitamin D levels.Researchers also have noted variations in vitamin D synthesis, with some people failing to raise their levels of the vitamin even when taking high-dose supplementsDr. Qi Dai, the lead author on the latest study and a professor of medicine at Vanderbilt University Medical Center, said their research explains why.
