I only take Vit D3 capsules. I don’t subscribe to the multivitamin con, because I eat a varied omnivore diet. Meat, fish, fruit and veg. And as a doctor in hospitals or general practice, I have never come across anyone with vitamin deficiency. It’s hard to get vitamin deficient these days, with so many foods, especially cereals and bread, are fortified with vitamins.
Vegans, of course, are at much greater risk of vitamin deficiency, mainly B12, which is rarely found in non animal foods, and where it does appear is not in the same essential quantity you need.
