Vitamin D3

Vitamin D3 mainly originates from animal sources such as fatty fish, liver, fish oil, and egg yolks. When our skin gets exposure to sunlight, it naturally produces vitamin D3. That is why, vitamin D3 is commonly known as the sunshine vitamin. The strength and potency of vitamin D3 also measures in international units (IU). Vitamin D interestingly appears to be more efficient in increasing levels of vitamin D in the blood. Although, there is a debate going on among scientists about the relevance of vitamin D3 hyper-absorption to human health. In order to maintain adequate vitamin D levels, it is important to regularly eat plenty of vitamin D rich foods and spend some time in sunlight. If someone suffers from vitamin D deficiency, the physicians generally recommend vitamin D3 supplements as they work more efficiently.
