Nature's Plus® Vitamin D3 5000 IU provides Vitamin D3, nature's most bioavailable form, in one easy-to-swallow softgel. Studies indicate that 5000 IU of vitamin D3 every day can help many people achieve optimal calcium absorption and support healthy bone density. Yet, according to the National Center for Health Statistics, more than 35% of Americans don't even get the minimum Daily Value (DV) of 400 IU, which only serves to prevent deficiency. Nature's Plus Vitamin D3 5000 IU provides the superior health benefits that can only be found at such high-potency levels.
