You can pay a lot for bariatric vitamins for either procedure...or you can be cheap like me, buy store brands (buy one get one free) and your nutritionist will still clear them for use:)
I don't get fancy chewable calcium. I get the rock hard june bug sized Calcium citrate monsters....and just hold them in my mouth with a swig of hot coffee until they start to errode. Then, I just munch them up into paste and swallow them. The taste isn't that bad, and the cost is exponentially less. I used to put them through a pill crusher and eat the dust with sugar free Cool Whip.
My multi vitamins are Store Brand (equivilant to Flinstone's Complete) kid's chewable vitamins in animal shapes...lol. I take two a day. I don't mind them.
I also take extra B Complex, B12 and D (because I'm deficient living in the north). I buy whatever's cheapest or pick up a sale on Amazon.
B12 and D...you can chew, they're bland and not offensive.
But B Complex? Yikes...you don't ever want to chew that. Bleh!
