Vitamin D3, sometimes known as the ‘sunshine vitamin’ is produced naturally in the skin when it is exposed to sunlight. You can also get it through certain foods. Although classified as a vitamin, D3 cleverly transforms into a hormone in the body and circulates in the bloodstream to help in the absorption of calcium and phosphorous.
This is perhaps one of the most vital functions that Vitamin D3 performs. We know that calcium builds and strengthens teeth and bone mass and is vital for bone development and growth. In addition, Calcium plays a role in the production of hormones in the body by transmitting nerve impulses to the brain.
Almost 99% of your Vitamin D supply is used for regulating the calcium in the body; the remaining part is utilised for strengthening the immune system and maintaining muscle strength
