Vitamin D is fat-soluble, which means absorption is promoted when taken with food, preferably a meal containing fats.

Synthetic D3 is often produced from animal sources or via chemical processes. Natural D3, as in this product, is organically obtained from plant-based sources such as lichen, without artificial additives.

Vitamin D2 (ergocalciferol) is mainly found in plant sources such as mushrooms, whereas vitamin D3 (cholecalciferol) is more often used in supplements and is also naturally present in some animal products.

The vitamin D3 in this supplement is derived from reindeer lichen (Cladonia rangiferina), a lichen that grows in extreme climates. It is a completely plant-based and organically certified source of vitamin D3, suitable for vegans.
