A revolution in D supplementation, it combines high-potency sources of D, essential cofactors and liver support nutrients to activate D so it can be used by the body, plus emulsifiers to support the healthy absorption of fat-soluble nutrients like vitamin D. This Bio-Aligned Formula® addresses multiple, interrelated body systems—including respiratory, liver, kidney, cardiovascular, antioxidant and musculoskeletal health—to support the immune system and make sure your vitamin D works hard for you.*

Directions: Take 2 capsules daily with food. Vitamin D is a fat-soluble vitamin, meaning that it does not dissolve in water and is best absorbed when paired with high-fat foods. For this reason, it's recommended to take vitamin D supplements with a meal for optimal absorption.
