Vitamin D is considered a pro-hormone, it cannot be created by the body and therefore must be taken in through diet and supplementation. Also, when the skin is exposed to the sun, our bodies make vitamin D- That's why it's often referred to as the Sunshine Vitamin. Vitamin D3 can be absorbed through sunlight or eaten in a few foods, it is often not enough to deliver the full range of benefits that this vitamin has to offer. It is for this reason that our supplement exists, able to provide you with a healthy, full dose every day. Our Vitamin D3 softgel is made in Pure Safflower seed oil*
