BackgroundMany respectable guidelines recommend lifelong vitamin B12 injections for Roux-en-Y gastric bypass (RYGB) patients in the absence of lack of consensus on the efficacy of oral route of prophylaxis and the appropriate doses needed for this purpose. The purpose of this review was to examine the published English language scientific literature in accordance with PRISMA principles to find out if orally given vitamin B12 is adequate for prophylactic purposes in RYGB patients and the… Expand
Comments on: “Oral Vitamin B12 Supplementation After Roux-en-Y Gastric Bypass: a Systematic Review”

This study lends further support to regular supplementation with vitamin B12, folic acid, and iron in people undergoing bariatric surgery. Expand
Anaemia After One Anastomosis Gastric Bypass
TLDR
The authors of this letter point out that others have found anaemia rates to be higher with SG than GB, Roux-en-Y gastric bypass in particular, and they further contend that the results might be due to the possibility that OAGB patients have a further reduction in capacity to absorb iron compared to those undergoing RYGB and this may well account for the suggested increase in anaemic rates following GB by Bailly et al. Expand
The Effects of Bariatric Surgery on Vitamin B Status and Mental Health
TLDR
Considering the important functions of vitamin B and the severe consequences associated with its deficiency following bariatric surgery, proper dietary intervention and administration of adequate supplements should be considered to prevent negative clinical outcomes. Expand

Optimization of Vitamin Suppletion After Roux-En-Y Gastric Bypass Surgery Can Lower Postoperative Deficiencies
TLDR
An optimized multivitamin supplement is safe and reduces the development of iron and vitamin B12 deficiencies after LRYGB, and iron deficiency was reduced after WLS Forte compared with sMVS. Expand
Are vitamin B12 and folate deficiency clinically important after roux-en-Y gastric bypass?
TLDR
Prophylactic oral iron supplements are recommended to premenopausal women who undergo RYGB to learn whether the risk of developmg these deficiencies decreases over time and to determine how readily patients who developed metabolic deficiencies after Roux-en-Y gastric bypass responded to postoperative supplements.

Can Composite Nutritional Supplement Based on the Current Guidelines Prevent Vitamin and Mineral Deficiency After Weight Loss Surgery?
TLDR
Use of a composite based on guidelines proposed by the AACE, TOS, and the ASMBS appears to be effective for preventing iron and vitamins A, B1, B12, and D deficiencies in the LRYGB patients during the first postoperative year. Expand
