Vitamin D3 180 gelcaps

  • Bioidentical Natural Vitamin D3


    Vitamin D3 levels are insufficient in up to 40% of American adults and in approximately 61% of our children.6 Vitamin D3 displays critical immune support for essential immune functions, including:

    (a) promoting balanced and appropriate healthy immune responses.7,8

    (b) promoting healthy immune surveillance and defensive performance.9,10,11

    One of the most well researched and clinically supported vitamins. Supports calcium absorption and bone health. It also provides potential support for breast, cardiovascular, colon and immune health.  This natural D3 form is four times more potent than synthetic vitamin D.*

    Our Vitamin D softgels supply this key vitamin in a highly-absorbable liquid softgel form.  They  feature 5000 IU of vitamin D3—the most bioavailable form of vitamin D.*
