Vitamin D is a fat-soluble vitamin, meaning your body absorbs it best when it’s taken with healthy fats. Unlike water-soluble vitamins such as vitamin C, vitamin D moves through the bloodstream attached to fat-carrying proteins. Without dietary fat, much of it passes through the unused digestive system, which is why people who take vitamin D on an empty stomach often see little improvement in their levels.

Studies have shown that taking vitamin D with foods rich in good fats, such as olive oil, avocado, nuts, or salmon, can improve absorption. One clinical review found that the presence of fat in the gut enhances how well vitamin D is absorbed. In simple terms, how you take vitamin D matters just as much as how much you take.

That’s why D3X is formulated in organic olive oil. Olive oil is a natural source of healthy fat that helps your body absorb vitamin D efficiently. This makes D3X a convenient, one-step solution: the vitamin D and the fat it needs come together in easy daily drops. You don’t have to time your supplement around meals or worry about poor absorption. Just pure, bioavailable vitamin D3 designed for optimal uptake.
