To start off Pre-Op Vitiamins its Chewable Multi, B-12, and Calcium but many of you are on...
Those are a good start. Many people will tweak what they take based on their labs. Personally, I get my labs every 6 months and have added different things as I need them. I follow the basics of my program, but follow my labs closely, and increase or decease as needed.
Iron is recommended for some, as is Vitamin D. maybe a B complex. Just need to see what your labs look like.
Calcium Multi and B12 are key.
good luck!
