Metformin Cause B12 Deficiency Risk

A high percentage of people, both pre-diabetic and diabetic take Metformin to control blood sugar. It can be helpful to many people but this study shows that a Vitamin B12 deficiency can develop from it. It is easily remedied but it must be watched and B12 supplemented appropriately.

Following participants with a high risk for type 2 diabetes, for more than 10 years, researchers have recently discovered that people who take Metformin (a common type 2 diabetes medication) for several years may have a heightened risk of vitamin B12 deficiency and anemia.

However, the Sr. author of the study doesn’t feel that the B-12 deficiency should prevent people from taking it. Rather, they should ask their doctor to routinely check their levels because prolonged deficiency has been linked to anemia, impaired cognition and dementia- yet it is easily reversible with treatment with pills or monthly injections.

There are more than three million cases of vitamin B12 deficiency each year in the U.S., which can be caused by diet or certain medical conditions. Symptoms include fatigue, and numbness or tingling.

People do not make vitamin B12 and need to consume it from animal sources or supplements. Vegetarians may get enough from eating eggs and dairy products, but vegans need to rely on supplements or fortified grains.
