Oral Vitamin B 12 Supplementation After Roux-en-Y Gastric Bypass: a Systematic Review
ConclusionThe review finds that oral supplementation doses of ≤ 15 μg vitamin B12 daily are inadequate for prophylaxis of vitamin B12 deficiency in adult RYGB patients but doses of 1000 μg vitamin B12 daily might be adequate. Future studies need to examine this and even higher oral doses for vitamin B12 supplementation for patients undergoing RYGB.
