Vitamin D and Constipation-. A Preventable Problem. Constipation is one of these signs of magnesium deficiency and if you are getting constipation from vitamin d, then your body is telling you that you ARE magnesium deficient and that you probably have been for a long long time.
One of the best ways to prevent constipation is to add fiber to your diet. Fiber helps to soften stool so it moves smoothly through the colon. There are two kinds of fiber: soluble and insoluble, and both work to prevent constipation. Soluble fiber dissolves in water. Good sources of soluble fiber include beans, fruit, and oats.
