Vitamin D – A bit of History

The term Vitamin D refers collectively to the vitamers D2 (ergocalciferol) and D3 (cholecalciferol) and their metabolites, which are all  functional in the body. People rarely get just one form of vitamin D. Dietary vitamin D2 comes primarily from plants, yeasts, and fungi; dietary vitamin D3 comes mostly from animals, although a supplemental form can also be produced from lichen. Both D2  and D3 require irradiation (e.g., from sun exposure) to be formed from their sterol precursors: ergosterol, a phytosterol, is transformed into ergocalciferol (D2); cholesterol, an animal sterol, is transformed into cholecalciferol (D3).

Until relatively recently, all food fortification of vitamin D was with D2. Vitamin D3 is also often used, but D2 is still more abundant, cost-effective, and has less ecological impact. In addition to making vitamin D in our skin, we can also obtain D3 from certain animal foods, such as beef liver, cheese, egg yolks, and fatty fish. Vitamin D3 sold as a supplement typically is derived from sheep’s wool (lanolin) although there are versions derived from lichen. Ergocalciferol (D2) can also be synthesized pharmaceutically and is available as a high-dose prescription medicine.
