The role of micronutrients on the treatment of diabetes

Abstract

In the last two decades, there has been a significant increase in the number of individuals worldwide who are affected by diabetes. This review article aims to explore the correlation between specific vitamins and diabetes. It has been observed that individuals with diabetes tend to have lower levels of certain antioxidant vitamins, namely A, C, and E. This decrease in vitamin levels is believed to be a consequence of the need to manage oxidative stress caused by issues with glucose metabolism. Additionally, retinol-binding protein plays a role in regulation and adipocytokine function. Diabetics also exhibit reduced levels of thiamine, pyridoxine, and biotin. Research has indicated that diabetes can hinder the absorption of various nutrients, including vitamins B9 and B12, necessitating frequent replenishment of these vitamins. Insufficient levels of vitamin D have been linked to an increased risk of developing diabetes and related complications such as cardiovascular disease. While some studies suggest that vitamin K supplementation may improve glucose metabolism, it remains uncertain whether it can prevent or repair oxidative damage. Excessive vitamin supplementation has been shown to have negative effects, as demonstrated by numerous studies. The review that follows will analyze the association between several nutrients, specifically vitamins A, D, C, B3, B6, B9, Zn, B12, E, B1/K, and iron, and the pathways implicated in diabetes, as well as their potential regulatory effects.
