Vitamins K and D work synergistically in your body, meaning that they enhance each other’s effects. Interestingly, liposomal forms of this vitamin have been shown to be better absorbed than tablet forms of vitamin D supplements ( 13). Liposomes are tiny spheres of fat used as carriers for vitamin D and other fat-soluble nutrients in certain supplements ( 13). Who it’s best for: people who prefer a liquid supplementĭesigns for Health’s Liposomal Vitamin D Supreme liquid drops combine vitamin D with vitamins K1 and K2.The company also states that its supplements are third-party tested by organizations such as Eurofins, Intertek, Silliker, and Advanced Laboratories. What’s more, Pure Encapsulations thoroughly tests all products and manufactures supplements in a facility that exceeds the standards set by USP. It’s not only vegan but also free of gluten, tree nuts, peanuts, genetically modified organisms (GMOs), and artificial colors or flavors. Pure Encapsulations, for example, offers a liquid D3 product that’s derived from sustainably harvested lichen. Recently, companies have found a way to manufacture vegan-friendly vitamin D3.

However, research shows that D2 isn’t as effective at increasing blood levels of the vitamin as D3 is ( 11).

Many vitamin D3 supplements are derived from fish or sheep’s wool, meaning they’re inappropriate for vegans ( 5 ).Īs a result, many vegan products contain ergocalciferol (vitamin D2) - a form of vitamin D that’s vegan since it’s derived from yeast or mushrooms.

Who it’s best for: people who prefer a liquid form and are following a vegan diet.
