Essential elements d3 provides 125 mcg of this key vitamin, needed to support vital body function and promote greater whole body health. Vitamin d3, delivered in organic avocado oil for improved absorption, is clinically shown to support healthy bone, teeth, and muscle function, while also assisting the immune, cognitive, and cardiovascular systems that are essential to your well being. The Science / Health Benefits: Vitamin d3 is created naturally by your body when skin is exposed to sunlight. d3 supplements ensure you always have enough to combat vitamin-D deficiency, even during the winter months or if you spend most of your time out of the sun. Vitamin d3 is essential for bone health and bone density. While calcium is closely associated with bone health, d3 allows the blood, and thereby the rest of the body, to absorb more calcium from the gut. Apart from facilitating the use of minerals in the body, d3 also encourages muscle function. Research has suggested a link between low vitamin D and low levels of muscle mass. Ingredients: Vitamin d3 (cholecalciferol) is created by removing it from naturally occurring lanolin. By using organic avocado oil as a carrier, the oil-soluble d3 is made more bioavailable, meaning your body is able to more efficiently use it.
