Vitamin D Deficiency: How Much Vitamin D Is Enough?

Vitamin D is a fat-soluble vitamin that regulates the absorption of calcium and phosphorus as well as facilitates normal immune system function. This vitamin is an essential nutrient important for strong bones. Vitamin D has 2 forms: D2 (obtained from foods you eat) and D3 (obtained from sun exposure). Vitamin D is produced by the body when your skin is exposed to sunlight. You can also get vitamin D through certain foods and supplements. It’s important to get enough of this vital nutrient so you don’t end up with a vitamin D deficiency.

Benefits of Vitamin D

Vitamin D can boost your immune system, support muscle function, keep your heart healthy, and aid in brain development. Vitamin D may also reduce your risk of multiple sclerosis and depression.

Your body needs vitamin D to help absorb the calcium and phosphorus in your diet that makes for strong bones. Vitamin D deficiency can cause bone loss, low bone density, and increase your chances of breaking bones. Vitamin D deficiency can also cause rickets in children and a condition called osteomalacia in adults. Symptoms may include weakness and bone pain.
