Andrew Lessman's Vitamin D3 4000 contains 4,000 IU of Vitamin D3 in its most active and beneficial form – Cholecalciferol. Decades of overwhelming science has shown Vitamin D3 to be the single most important vitamin to supplement, since it is not readily available from even the healthiest diets. Vitamin D plays a multitude of vital roles in the body, including its essential role in all Calcium absorption, which makes Vitamin D as important as Calcium for bone and skeletal health. Vitamin D also possesses a long list of other benefits that have physicians and experts urgently recommending higher intakes. These other benefits include Vitamin D's essential role in supporting healthy immune system function, along with positive mood and brain function. Research has shown that we cannot rely on sun exposure to meet our Vitamin D requirements, and since there are also no abundant sources of Vitamin D in our diet, supplementation has become the only reliable source. Our extremely affordable Vitamin D3 4000 provides Vitamin D in its ideal form in an ultra-small, easy-to-swallow capsule.

Contains no additives or common allergens Contains no milk, soy, yeast, wheat, gluten, sodium, salt, sugar, fat, cholesterol, color, preservative, common allergens, genetically modified (GMO) ingredients or manufacturing additives.
