Calcium and vitamin D are interdependent for proper absorption and metabolism of calcium and phosphorus. Vitamin D helps maintain normal calcium levels in the bloodstream and is necessary for the remineralization, growth, and repair of bones. A healthy diet rich in calcium and vitamin D, along with sun exposure, is the best way to ensure adequate amounts for the body’s functions.
Calcium and vitamin D are closely related because the two nutrients are mutually dependent when it comes to performing their functions in the body. For example, vitamin D regulates the absorption and metabolism of calcium and phosphorus; In fact, it is absolutely necessary for the proper absorption of calcium. Most people associate strong teeth and bones with calcium’s role in nutrition, but unabsorbed calcium can’t do its job. Another connection between calcium and vitamin D lies in the fact that vitamin D helps maintain normal calcium levels in the bloodstream.
The effects of vitamin D in the body include the remineralization, growth, and repair of bones. It is interesting that a vitamin plays such an important role in maintaining healthy bones and teeth because such activity is usually associated with calcium and other minerals, not vitamins. Calcium and vitamin D are so closely connected that vitamin D has been added to some calcium supplements to increase absorption. However, calcium absorption can be increased naturally if a person receives adequate but healthy sun exposure, which stimulates the body to produce its own vitamin D.
The benefits of calcium cannot be considered completely independent of vitamin D due to the natural connection between calcium and vitamin D. For example, calcium is also necessary for the development and maintenance of healthy teeth and bones, proper blood clotting , absorption of vitamin B12, regulation of cell permeability and proper use of iron. These vital life functions are not associated with vitamin D as a single nutrient. However, this all changes when you consider the special connection between calcium and vitamin D.
So it would be correct to say that vitamin D is indirectly responsible for all of the same things that calcium is responsible for, because without vitamin D, the body cannot absorb the calcium that is put into it. Unlike vitamin D, which is not widely available in food, there are many good food sources of calcium. Dairy products, citrus fruits, figs, and dark green leafy vegetables such as kale, mustard, and turnip greens are excellent sources of calcium. A combination of a healthy diet rich in calcium and other essential nutrients, plus some daily sun exposure, is the best way to ensure that calcium and vitamin D are available to the body in adequate amounts to perform all of its functions. .
