Sports Research Vitamin D3 5000iu (125mcg) with Coconut Oil ~ High Potency Vitamin D for Immune & Bone Support ~ Non-GMO Verified, Gluten & Soy Free (360 Mini-Liquid Softgels)

HEALTHY BONES AND TEETH: Known as the "sunshine vitamin," Vitamin D helps maintain strong bones by helping you metabolize calcium and supports a healthy immune system. Our Vitamin D3 delivers the same biologically active form of vitamin D that is produced in the body from direct sunlight without the risk of unprotected UVA and UVB exposure. Daily intake is essential for calcium absorption and maintaining healthy bones and teeth.
COCONUT OIL: Vitamin D3 is fat soluble and it is difficult for the body to absorb if not taken with a fat, which is why we added coconut oil to our softgel capsule to aid your body with absorption. Our easy-to-swallow vitamin D3 capsules are the easiest, most convenient way to add this essential micronutrient to your daily ritual.
PREMIUM QUALITY: Sports Research takes pride in offering products that use only the best ingredients available so that you can have total peace of mind in the supplements that you are taking. Our vitamin D (as Cholecalciferol) supplement is certified non-GMO and free of soybean oil and safflower oil. Formulated with organic coconut oil.
