Question

Where do they get the vitamin d3 found in cows milk?

Answer 1

There are two sources for vitamin D3: one is synthetic and one is natural...lanolin, or cholesterol from the wool of healthy sheep, is the natural source of supplementation D3."

I'm not sure which is used in milk ( I have read it is natural but can't verify this). Personally I think on strictly a health level milk is worse for the health than most meats. It creates a lot of mucus which lowers the immune system and creates haven for bacteria, increases risks for several types of cancer, and I also believe facilitates severe allergies (and I'm not talking about simple intolerance.

BTW, you can get a significant amount of vitamin D just by getting exposure to the sun.

Answer 2

The vitamin D found in commercial milk is actually a synthetic steroid.  It is add to the animals feed, then again to the final product after it has been pasturized.  Commercial milk also contains antibiotics, growth hormones and other medications the cows were given to help overcome the deplorable conditions they are kept in.  Raw, organic milk fresh from the cow contains vitamins (including d) that the cow got from free range pasturing and sunshine.

Answer 3

Vitamin D3 is made from sheep's wool. To be more precise, it's made from lanolin, which is the grease in sheep's wool. This is why it's not vegan.

The sheep doesn't need to be killed for lanolin, but there are issues with wool production, especially with merino sheep.
