Dr. Christian Mann's patients, help plz!

 Hey everyone. I just basically need to know one thing. What vitamins do I need to be taking? The only thing I am taking is my multi vitamins because thats all I was told to take. So many people r telling me I should be taking calcium and this type of medicine and that type of medicine. It's been 3 years since my surgery and I hate to think i've been doing everything wrong. PLEASE let me know what was told to u to take. Thanks so much in advance!
