A comprehensive new study has revealed that nutrient deficiencies are rampant among individuals with type 2 diabetes, a condition that affects approximately 90% of the global diabetic population, according to the Centers for Disease Control and Prevention (CDC). The study compiled data from 132 studies worldwide, encompassing over 52,000 participants living with type 2 diabetes. The findings are concerning, indicating that a significant proportion of these individuals suffer from deficiencies in key vitamins and minerals critical for maintaining overall health.
Globally, around 60% of individuals with diabetes have been found to have low levels of vitamin D, a nutrient essential for bone health and immune function. Furthermore, 42% of people with diabetes experience magnesium deficiency, while 29% lack adequate levels of vitamin B12. These deficiencies are particularly prevalent among those living in the Americas, placing them at an elevated risk for complications associated with type 2 diabetes.
The ramifications of these deficiencies are profound. About 45% of individuals suffering from complications due to type 2 diabetes were found to be deficient in multiple micronutrients. Compounding this issue, the study highlighted that vitamin D deficiency rates can reach as high as 31% among Black Americans, a demographic already at a heightened risk for various health disparities.
“People with diabetes may follow restrictive diets to manage their blood sugar levels, which could inadvertently lead to inadequate micronutrients,” – Daya Krishan Mangal, MD
The CDC has previously estimated that in the general U.S. population, nutrient deficiencies range from less than 1% for folate, vitamin A, and vitamin E to about 10% for nutrients such as vitamin B6, vitamin D, and iron. However, the prevalence of such deficiencies in people with type 2 diabetes is notably higher. Poor management of the condition can prompt the body to expel vital micronutrients. Metformin, a common medication prescribed to manage type 2 diabetes, may interfere with vitamin B12 absorption, exacerbating this issue.
“Routine screening for specific deficiencies, such as vitamin D and magnesium, could help identify and address potential gaps in nutrition,” – Mangal
Zinc deficiency poses another concern by disrupting B cells responsible for glucose metabolism. The role of diet also emerges as a critical factor; excessive consumption of ultra-processed foods can contribute to the onset of type 2 diabetes. Alarmingly, women appear to be more susceptible to micronutrient deficiencies than men, with 49% of women affected compared to 45% of men.

Bahtiyar further elaborates on the impact of chronic conditions such as heart disease, neuropathy, and kidney disease on nutrient absorption. These conditions often alter the body's ability to assimilate and utilize essential micronutrients effectively.

“When blood sugar is high, the body tries to flush out the excess glucose through the urine, and this process also flushes out magnesium, leading to even lower levels of these nutrients,” – Bahtiyar
Addressing these deficiencies demands a multifaceted approach. Experts suggest that lifestyle changes and healthy dietary choices are paramount in managing nutrient shortfalls. The absence of routine micronutrient testing in standard type 2 diabetes management protocol may require reevaluation. Individuals are encouraged to discuss screening options with their healthcare providers.
“Vitamin B12 improves metabolism by breaking down the foods you eat more efficiently,” – Beth Czerwony, RD
The modern lifestyle often prioritizes convenience over quality nutrition, leading to diets deficient in nutrient-rich whole foods.
“The modern lifestyle that prioritizes convenience and speed often leads to a lack of nutrient-rich whole foods in our diets,” – Bahtiyar
This trend creates a vicious cycle that complicates the management of type 2 diabetes further.
