Zenement Vitamin D3 4000 IU, 365 softgels

Vitamin D3 (cholecalciferol) is a fat-soluble vitamin that helps the body absorb calcium and phosphorus to build and maintain strong bones and helps the immune system function normally in the face of external stress. It is produced naturally by the body in response to sunlight and is found in certain dietary sources such as oily fish, mushrooms and eggs. However, since it can be difficult to achieve the required daily amount from sunlight and food alone, taking supplements can help maintain satisfactory vitamin D levels throughout the year. Due to limited exposure to sunlight, dark skin or age can lead to Vitamin D deficiency in the body. Also, diet may not be sufficient to maintain normal levels, so you may consider taking a vitamin D3 4000IU supplement with 100% natural ingredients.
