I have decided I want to try vitamins as a way to improve my nodular acne, I have been researching vitamins and so far I have read that the vitamins which supposedly help are Vitamins A, E and C, Selenium, Zinc and MSM. Is it okay for me to take all of these vitamins everyday? How much of each should I take each day? And can anyone suggest a routine for me to take the vitamins for example take certain vitamins in the morning and take the others at night?

Thanks
