Jamieson Vitamin D 1000 IU is a high-potency formula that helps support healthy bones and teeth, as well as immune system function. Each softgel contains 1000 IU of vitamin D3, the most easily absorbed form of vitamin D, derived from natural sources. This supplement is especially important for those who have limited sun exposure or follow a vegetarian or vegan diet, as vitamin D is primarily obtained through sun exposure and some animal-based foods. With Jamieson Vitamin D 1000 IU, you can be confident that you are getting the vitamin D you need to support your overall health and wellness.
