Source of Vit D3 that's not from Lanolin
1) I am ALLERGIC to lanolin and I understand that the 2 sources of Vit D3 are Lanolin and Fish oil. I have had 2 episodes recently that the Supplement Companies (Metagenics AND GNC) gave me 2 different answers as to the SOURCE of THEIR Vit D3. How can I be sure that I get the Vit D3 FROM the FISH OIL Source?
ALSO ---
2) I was recently told that I could take Vit D3 tablets from lanolin BECAUSE It is extracted from lanolin, BUT there is no lanolin in it. This does not make sense to me because since it is gotten FROM the lanolin. How could ALL the lanolin -- as its source of the product be eliminated? I am not a chemist, BUT I am trying very hard to get CORRECT information. I do NOT want to get any internal, intestinal, inflammatory symptoms that would be very difficult --if not impossible----- to correctly diagnose.
Thank you so much for your help !!!
