They come in various forms, including tablets, chewables, and liquids, and can be found at most pharmacies and health food stores. It is important to consult with a healthcare professional before starting any supplement regimen.

Frequently Asked Questions (FAQs)
1. Should I take a calcium supplement with vitamin D?
Your body needs vitamin D to absorb calcium, but you do not have to take calcium and vitamin D at the same time. For the best absorption of calcium, make sure you get enough vitamin D.
2. Why do doctors prescribe vitamin D with calcium?
“Vitamin D is commonly prescribed for hypoparathyroidism [a condition that causes calcium deficiency, muscle cramps and spasms, weakness, and fatigue],” says Dr. Lukyanovsky. “Doctors might also prescribe it for osteomalacia, a condition where there's a depletion of calcium from the bone.”
3. Should I take calcium with vitamin D or just vitamin D?
The body needs vitamin D to absorb calcium. Without enough vitamin D, one can't form enough of the hormone calcitriol (known as the “active vitamin D”). This in turn leads to insufficient calcium absorption from the diet.
