In the randomized placebo-controlled HOME trial of 390 adults with type 2 diabetes (de Jager and colleagues, Long term treatment with metformin in patients with type 2 diabetes and risk of vitamin B-12 deficiency, BMJ, 2010), metformin lowered serum B12 by a mean of 19 percent over 4.3 years
For example, those with high blood pressure, heart problems, skin conditions, blood disorders, gout and low potassium levels should use vitamin B12 with caution and may want to consider talking to a trusted health care practitioner before starting supplementation
