I'll try to answer your question to the best of my ability but there are others here that have way better information on supplements that we should be taking piost bypass, look up Pam T her profile has a lot of good information in it.  

You should take a multi-vitamin, most people say to take two a day in fact because of what we malabsorp, personally I take one a day, but keep telling myself I'm going to start taking two throughout the day, it just hasn't happened yet.
Around 2000mg of calcium (I hope this is the right number, it's what I get in), taken in doses of no more than 500mg at a time because that is all you will absorb at once.
Iron supplement (I have a prescription so I'm not sure how much you should be getting, this is a hard one for me to get in because it causes severe constipation in me even though I've tried several different types and several different remedies to no avail), it is best to take iron with Vitamin C as it helps it to absorb.
Vitamin B12...sublingual, not in a pill that you swallow...I take 1000mcg a day...
I also take Vitamin D in dry form, got it from Vitalady and I take 10000iu's about 5 times a week with one of my doses of calcium.

Many people also take a b complex vitamin, but I'm lucky to get all those others in so I rarely remember to take one of those...also don't take calcium and iron at the same time, they hinder absorption of each other. 

Good luck, I agree that it's hard to remember to get all the vitamins in when you have to split them up in so many doses.  Some people set reminders on their cell phones so that they can remember to take them every couple of hours and get them all in in a day.  WTG on your weight loss, I've lost 88.4 pounds since surgery and have about 35 to go to my first goal and 45 to go to my ideal goal.  

Congratulations! 

I still have at least 12# to lose to get there (my scale says 216, doctor says 211).  I started off at 334 though so I might have had a ways to go compared to some.

Finally finish all testings, labs, pre-ops. Got a date. January 15, 2010. Dr.Paul Enochs,surgeon.

Congrats!  I posted a similar post yesterday. LOL!  I am also a "slow" loser, but I'm ok with that.  As long as the scale keeps going down, I'm happy.  Happy Happy Holidays!

I barely ever get in here anymore, but have been a slow loser from the start and had to share how happy I am this Christmas.  I weighed in a few days ago and had hit 199.8, as of this morning I am 197.4.  I love that I can go to see family members for Christmas knowing I am no longer in the 200's!
I know I have read others who weren't fond of how slow they were losing doing this, so I thought I would as well.  I have had many many stalls, had my protein intake up to 130 grams a day for a few months because my pre-albumin levels won't get up there where they want them, but it actually dropped a few tenths on the higher protein and it had me up to about 1200 calories a day so my weight was barely budging at all during that time.  Found out I had thyroid problems a few months after surgery, so now on synthroid.  It may have been a long hard road for the past 8.5 months, but it sure seems worth it when I see I have lost almost 100 pounds and when I am able to do things with my family all the time now.  Shoot, I even put on a dress I had made for a friends wedding back in the mid 90's and even put on a dress I wore in high school in 84 for show choir today...and they all fit!

Starting weight (Sept. of 08)-194.4
Pre-surgery weight (3/31/09)-169
Current weight-197.4
Clothing size-16/18 or XL/1X
No more high BP, no more depression meds, no more high cholesterol and the good cholesterol is almost into the normal level finally (it was at a 5 a couple of years ago).  Labs are all good except te good cholesterol still needing a tiny bit more and the pre-albumin being a tad low but at a level the surgeon can live with for now.

I love this new life!  Even if I am having fun trying to find some warm clothes to wear since I am always freezing and all of my long sleeved clothes are way too many sizes too big LOL
