Which vitamin supplements interact negatively and should not be taken together?

List is too long: There are too many out there; good rule of thumb is to avoid taking too many things together; find a good whole food organic supplement that provides everything. My favorite is Alpha sun from simplexity health or moringa tree from zija. For details check my website at www.Medacpc.Com.

May not need any: If you are eating a mixed diet, you probably do not need any supplements. If you must any over the counter multivitamin and oral iron will more than suffice. Have a healthy diet, exercise, drink plenty of water, have safe sex, if you do, and get HPV vaccine. Wish you good health!
