BioTechUSA Vitamin D3 50 mcg (60 and 120 tablets) contains vitamin D3 in the form of cholecalciferol. This supplement is a simple way to take a substantial amount of vitamin D3 daily. The tablets are small, easy to swallow, and intended for adults who have an increased need for vitamin D.
Vitamin D2 is mainly derived from plant sources such as mushrooms, while D3 usually comes from an animal source (sheep's wool fat). Both forms are used in supplements. Vitamin D3 is considered the superior form.
IU stands for International Units; 2000 IU is equal to 50 micrograms (µg) of vitamin D3 per tablet.
Vitamin D3 in this product is traditionally derived from lanolin, a natural component of sheep's wool.
Fatty fish, cod liver oil, eggs, and fortified dairy products are good sources, along with sunlight.
