I don't think it needs to be higher than non-bariatric patients. Although we don't absorb it well due to our lack of intrinsic factor, so we have to supplement. I was never told it had to be above a certain amount. That said, a lot of us feel better when our B12 levels are up over 1000 (higher than normal B12 levels aren't dangerous, though - when mine got up over 2000 a couple of times, I was just told to cut back a bit on my supplementation).
Superior Source B12.
I started out with the 1000 mcg tablet but have been using the 5000 mcg tablet for the last three years or so. I only have to take that one once every two weeks (can't remember how often I took the 1000 mcg version - maybe a couple times a week?). You may have to play around with the frequency to see what does the trick for you. I think I started taking the 5000 mcg one since it was cheaper in the long run since i only had to take one tablet every two weeks.
EDITED to add: Here's a better picture of it. It comes in 1000, 5000, and 10,000 mcg. As I mentioned above, I take one 5000 mcg tablet once every two weeks
Whats the optimal B12 lab value that bariatric surgeons recommend...in other words, should our levels be kept higher than non-bariatric patients?
on labs the end of oct2021, my b12 was 1650. My dr was thrilled. I take Mary Ruth?s methyl b12 sublingual spray. It is 1500 mcg per two sprays.
I buy it on Amazon about 24.00 for one ounce.
