@Mandy those aDEK's are prett useless. They sound perfect because they contain all the fat soluble vitamins that we need, but they contain so little of each that there is no way they can compensate for our malabsorption of these vitamins. You really need to get the separate dry D, A, and K, and then follow your labs. Vitamin E deficiency is uncommon (I used to say never happens but apparently it can happen occasionally) but the other three are vital.
And of course also a good multi (doesn't have to be a "bariatric" multi, just get the Costco stuff), and your calcium citrate, and zinc. And some people need copper, some don't, again follow your labs. I use the bariatric advantage calcium because I have so much trouble with large pills, but if you're not like me, you can buy that at Costco as well and save some money. Just be sure to take 2 at a time, because the correct dose is 500 mg and the pills only contain 250 mg each.
