Study Finds Common Vitamin and Mineral Deficiencies Among People With Type 2 Diabetes

A large global review of 132 studies involving more than 52,000 adults with type 2 diabetes found that many people with the condition are deficient in key micronutrients, particularly vitamins D and B12 and magnesium. The analysis revealed that over 45% of individuals with type 2 diabetes have multiple nutrient deficiencies, and that women are more likely than men to be affected. Vitamin D deficiency was the most widespread, present in about 60% of participants, followed by magnesium deficiency in roughly 42%. Among those using metformin, a common diabetes medication, nearly 29% were found to have low levels of vitamin B12. Although the study could not determine whether these deficiencies contribute to the development of diabetes or result from it, researchers noted a strong correlation between the two. The article emphasizes that these deficiencies are not exclusive to people with diabetes; many in the general population also fall short of recommended levels of these micronutrients. T
