One thing we have learned as a group is to let the talk about what vitamins we need and how to eat LONG term as a DS'er to go in one ear and OUT the other. MOST surgeons are excellent cutters but are LOUSY in the vitamin/long term eating advice. And the NUTS are not much better. Chewable...nope. Just pills ADEK...forget ANYTHING that is marketed to bariatric patients and do NOT use an ADEK multi. 1) They are expensive and worthless 2) A generic centrum EQUIVALENT multi works just fine. I use the Kirkland Daily Multi (found at Costco) 3) For me...and this is based on MY labs, I do not take ANY A, E or B's at all other than what is in my multi. But I have to take significant amounts of DRY D3 and K. IF I used an ADEK multi, I would be toxic on A & E LONG before getting enough D or K. 4) Calcium needs to be a calcium CITRATE, If it doesn't say citrate ON the front label, it's the wrong one. 5) Iron...a carbonyl iron and/or heme iron is best if you can tolerate oral iron. Not everyone can. 6) Cost per month varies on what YOU need based on yoru own labs. What I spend is not the same as what others need. The prescription D you are being given by your doctor will be worthless once you have the DS. You will need DRY based A and D and E and K (NOT a combo) And welcome.
