BIOMOLECULES AND ENZYMES

Detailed explanation-1: -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.

Detailed explanation-2: -Vitamin D is both a nutrient we eat and a hormone our bodies make. It is a fat-soluble vitamin that has long been known to help the body absorb and retain calcium and phosphorus; both are critical for building bone.

Detailed explanation-3: -Many calcium supplements also contain vitamin D. There are two types of vitamin D supplements. They are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Both types are good for bone health.

Detailed explanation-4: -Calcium and vitamin D work together to protect your bones-calcium helps build and maintain bones, while vitamin D helps your body effectively absorb calcium. So even if you’re taking in enough calcium, it could be going to waste if you’re deficient in vitamin D.

Detailed explanation-5: -To absorb calcium, your body also needs vitamin D. A few foods naturally contain small amounts of vitamin D, such as canned salmon with bones and egg yolks. You can also get vitamin D from fortified foods and sun exposure.
