Vitamin D can be found in only small amounts in just a few foods, including fatty fish. To make vitamin D more available, it is added to dairy products, juices, and cereals so that they are fortified with vitamin D. But most vitamin D 80% to 90% of what the body gets is obtained through exposure to sunlight. In recent years, vitamin D deficiency has become more recognized, while simultaneously, the knowledge of roles this vitamin plays in many health issues has expanded. It is therefore prudent that individuals should consider supplementing with vitamin D regularly, particularly those with darker skin, who live in northern climates, are elderly or spend most days indoors since these groups have a decreased ability to make D3 by sunlight exposure.
- One drop provides 1000 IU of vitamin D3.
