August of this year I started to take vitamins on a regular basis. Since then I have been breaking out really bad. Is it possible that a certain vitamin in my mult is causing this? If so which one could it be? Is there a vitamin or something that can make my acne go away? Thanks in advance.
What kind do you take? It could be an allergy to an ingredient. I only use hypoallergenic vitamins from the Vitamin Shoppe (Twin Lab and Country Life). If you have trouble with digestion this could also cause a problem. In that case you need enzymes.
Other than the iodine mentioned above, excess vitamins B6 or B12 (any amount over 300% of the RDA) can cause acne in some people. Some people can have a reaction to oil-based vitamin E, but can take dry vitamin E. I suggest you experiment to narrow it down.
