Insulin resistance will not affect your ability to absorb topically-applied magnesium into your skin and from there into your bloodstream. Insulin resistance interferes with the process of transporting the magnesium out of the blood and into the cells of the body for use and storage.Suzy wrote:thank you Gabes. i just hope my insulin resistance doesn't impede my absorption of magnesium too much.
Higher rates of vitamin D should only affect magnesium levels if your diet contains a lot of calcium. Calcium does not interfere with magnesium absorption, but it depletes magnesium because magnesium has to be used in order to transport the calcium out of the blood. Too much calcium in the blood is dangerous, so the body assigns priority to maintaining a normal blood level of calcium. Therefore magnesium usage will be higher with higher calcium levels.
Vitamin D enhances calcium absorption into the bloodstream. Therefore, whenever there is an excess amount of calcium in the diet, more of it will be absorbed into the bloodstream when higher amounts of vitamin D are present. That will prompt additional magnesium usage. So that's how higher vitamin D intake can cause increased magnesium depletion. IOW, it depends on how much calcium is in your diet (especially calcium supplements).
