In a study published in the US National Library of Medicine National Institutes of Health, association of vitamin B12 with obesity, overweight, insulin resistance and metabolic syndrome were investigated.
The study noted: “The study enrolled 976 patients (obesity: 414, overweight: 212, and control: 351).
“Vitamin B12 level was significantly lower in patients with obesity and overweight than healthy individuals.”
The study concluded that low vitamin B12 level was associated with obesity and overweight, but not with insulin resistance, metabolic syndrome, and gender.
“Vitamin B12 was negatively correlated only with body mass index.”
