After six months a wrong dental diagnosis led to pain treated with high doses of OTC pain meds. That caused high liver enzymes which led to recommendation to cease supplements and pain meds. I n less than a month the liver was fine, but aches overtook body. I complained my bones ached. WHY? Remember those supplements? I stopped taking B12 and vitamin D3, which gave me many symptoms attributed to deficiency.
I did a lot of things wrong, trying to assure my liver recovered. Sudden withdrawal is never recommened.
Also, if we need D and B12 that comes from dairy and meat, then why is being vegetarian and dairy free optimum? D is absorbed after after acid in stomach breaks it down. A vegetarian diet is alkaline. Dairy is acidic. Mmmmmmm……
