Nowadays, people take many types of supplements to fulfill their nutritional needs. One of these is Vitamin D3. Generally doctors recommend consuming it to keep bones strong, maintain immunity and muscle health. But you will be surprised to know that most of the Vitamin D3 capsules available in the market are prepared from sheep’s wool.

If you are a vegetarian or vegan, then taking animal-based supplements may not seem right to you. So let us know the whole truth behind this and how much it means to you-

After all, how is Vitamin D3 made from sheep’s wool?

The lanolin present in sheep’s wool is involved in the process of making vitamin D3, but it does not harm the sheep.

First of all let us understand how Vitamin D3 is made from sheep’s wool. Actually, the reason behind this is lanolin. It is a waxy substance, which is found naturally in sheep’s wool. This lanolin protects sheep’s wool from rain, dirt and weather. The best part is that sheep are not harmed to obtain lanolin. It is collected during shearing their wool. The process of producing Vitamin D3 from sheep’s wool is as follows-

  • First of all, lanolin is extracted from sheep’s wool.
  • Then the compound called 7-dehydrocholesterol present in it is separated.
  • This compound is exposed to ultraviolet rays in a controlled environment.
  • After this it gets converted into cholecalciferol i.e. Vitamin D3.
  • This vitamin D3 is chemically exactly the same as our body produces itself when exposed to sunlight.

Is Vitamin D3 made from sheep’s wool safe?

After knowing the truth about Vitamin D3, the question that comes in everyone’s mind is whether Vitamin D3 made from sheep’s wool is safe. According to experts, Vitamin D3 made from lanolin has been used for a long time and is considered safe and effective. Experts say that the body does not care from which source vitamin D3 comes. It recognizes only the vitamin D3 molecule and uses it in the same way.
