I was taking vitamin D3,5000iu's, long before seeing Bariatrics, I've yet to go on the 2-week liver cleanse diet prior to surgery, and am still doing the 30% weight loss on my own, I have lost 20%, already. My Bari- Dr. said to wait for the call to start the liver cleanse diet, as they are sending into insurance for authorization. I have been taking calcium citrate 250 mg. with vitamin D3, each chew, for a total of 1500 mg. The nutritionist's instructions are to take 1200-1500 mg. daily, so that means 2 chews 3 x daily to get 1500, as 2 of them only comes up to 500 mg. I was told to take sublingual B12, but I don't remember if I was supposed to take under the tongue liquids or tablets, and wasn't told how much mg's so I am following the bottle instruction. I stopped my vitamin D3,5000ui, I was taking from the PCP Dr. The total D3 in the chews that many times a day comes up to about 750, and 5,750 iu' seems like an awful lot, to take Then there's the multivitamin, I wasn't told I had to get chewable, until I told the Bari Dr. I bought complete multivitamins with iron, but they are capsules,he said get Flinstones chewable complete, so I did, (gummies) only to get them home and find IRON nowhere on the bottle. I went back to the store and they had Flinstones complete with IRON in chewable tablet form. It really is irritating when they say take to two calcium chews, and leave out how many mg's.you have to take 1200-1500 a day according to nutritionist yet two chews at 500 mg's comes up to 1000 mg's. I think it would be very beneficial If they'd inform you how many mg's of this and that you're supposed to have and not just a quantity, and a name, of how many pills and chews since they have different set amounts, in iu's, and mg's, and milliliters. I'm not even sure if I should be taking them right now, prior to surgery or liver cleanse but figure it couldn't hurt. Yes, I have inquired and the nutritionist pretty much said not make a big deal out of it, yet throughout my pamphlet, the Dr. gave me said get used to taking it. So any advice? should I stop taking all this and wait till I get the call, and instructions, or keep doing what I'm doing??
