Vitamin D helps the body to absorb calcium, making it a critical part of healthy bones, but it also functions in immune and cardiovascular health, cell growth and inflammation moderation. Few foods in nature contain Vitamin D and 75-90% of people in the U.S. are deficient in this essential vitamin. For those that live in Northern latitudes and/or who avoid the sun, it is even tougher to get enough of this super vitamin. New research indicates that Vitamin D-3 may be twice as effective as Vitamin D-2 at raising nutrient levels in the body, making this high-potency gel capsule an important part of nutritional supplementation. This is an ideal source of Vitamin D-3 that is free of gluten, wheat, dairy, soy, yeast, sugar, sodium, artificial flavors, sweeteners, preservatives and colors. It is a minimally processed product from a natural source in an easily absorbed softgel capsule.
