Vitamin D-3 Booster is a straightforward daily softgel built around one well-studied nutrient. Each serving supplies 1000 IU of cholecalciferol, the same form of vitamin D the skin produces in response to sunlight and the form the body uses most efficiently. It is designed to help maintain everyday vitamin D status through the winter and shoulder seasons, when shorter days, indoor work, and northern latitudes leave most adults short on the sun exposure their skin would otherwise convert.

Vitamin D is fat-soluble, so absorption depends on a little dietary fat. We suspend the D3 in cold-pressed extra virgin olive oil with a touch of MCT, so the active arrives in the carrier it needs without a separate spoonful of oil. A small amount of rosemary extract protects the oil from oxidation across shelf life. The softgel is small, neutral-tasting, and built for adults who want a reliable daily D routine.
