articles Review The Relationship Between Vitamin K And Diabetesstud

Reviewing the literature on the relationship between vitamin K and diabetes reveals a growing body of evidence suggesting that vitamin K, particularly K2, may have a beneficial role in the management and prevention of type 2 diabetes mellitus (T2DM). Diabetes mellitus, characterized by chronic hyperglycemia, leads to long-term damage of vital organs, notably the eyes, kidneys, nerves, heart, and blood vessels (Senyigit, 2019). The prevalence of T2DM is rising globally, disproportionately affecting women, especially postmenopausal women, underscoring the importance of targeted nutritional interventions (Li et al., 2018). The scientific investigations reviewed focus on the biochemical effects of vitamin K2 in insulin sensitivity, glucose metabolism, and bone health, which are critical considerations in diabetic care.

Senyigit (2019) conceptualizes diabetes as a metabolic disorder involving insulin deficiency or resistance, leading to persistent hyperglycemia. The article emphasizes the significance of vitamin D3 and K2 in modulating metabolic parameters associated with T2DM. Specifically, the review explores how supplementation with vitamin K2 influences osteocalcin forms, insulin sensitivity, and glucose regulation. Osteocalcin, a vitamin K-dependent protein, plays a key role in glucose regulation, and its carboxylated form (cOC) is associated with improved insulin sensitivity. The research indicates that vitamin K2 supplementation enhances osteocalcin carboxylation, thereby potentially improving glucose homeostasis in diabetic patients (Senyigit, 2019).

Li et al. (2018) further elucidate the role of vitamin K2 in diabetes by highlighting its impact on insulin resistance and pancreatic beta-cell function. Their review of observational and experimental studies suggests that increased vitamin K2 intake correlates with a reduced risk of T2DM. The authors also discuss the synergistic action of vitamin K2 with vitamin D3, which improves calcium absorption and bone mineralization, processes often compromised in individuals with diabetes. Notably, their studies show that vitamin K2 supplementation can decrease Homeostatic Model Assessment of Insulin Resistance (HOMA-IR) scores, indicating improved insulin sensitivity. Furthermore, they suggest that vitamin K2 supports the gamma-carboxylation of osteocalcin, which in turn stimulates insulin secretion and enhances pancreatic function (Li et al., 2018).

Mechanistically, the studies suggest that vitamin K2 influences glucose metabolism through multiple pathways, including modulation of osteocalcin, adiponectin, and inflammatory mediators like NF-kB. Adiponectin, which increases with vitamin K2 intake, enhances insulin sensitivity, whereas the reduction of NF-kB activity decreases inflammation, a known contributor to insulin resistance (Manna & Kalita, 2017). The intersecting pathways highlight the potential of vitamin K2 to serve as an adjunct therapy for improving glycemic control and preventing diabetic complications. Nonetheless, the evidence indicates that the effects of vitamin K2 may be more pronounced in populations with vitamin D deficiency, emphasizing the need for individualized nutritional strategies (Manna & Kalita, 2017).

Biochemical analyses reveal that vitamin D3 and K2 supplementation synergistically promote the carboxylation of osteocalcin, which is linked to higher insulin secretion and better glucose tolerance. After intervention, reductions in fasting glucose levels and improvements in HOMA-IR and HOMA-B scores were observed, especially in the group receiving both vitamins. Interestingly, the influence on bone metabolism, with increased calcium deposition and mineralization, parallels metabolic improvements, suggesting interconnected pathways between bone health and glucose regulation (Li et al., 2018; Senyigit, 2019). These findings bolster the hypothesis that vitamin K2 supplementation can modulate key metabolic markers, thereby serving as a protective factor against T2DM progression.

Despite these promising findings, several limitations persist. Many studies have small sample sizes or are observational, which restricts definitive conclusions regarding causality. Variability in dosage, form of vitamin K2 used, and participant characteristics introduces heterogeneity, complicating comparisons across studies. Additionally, the long-term safety and optimal dosing of vitamin K2 remain unclear. It is also uncertain whether supplementation alone suffices or if it should be combined with lifestyle interventions such as diet and exercise for maximal benefit. Addressing these gaps requires large-scale randomized controlled trials with rigorous methodology to establish standardized guidelines for vitamin K2 use in diabetes management (Li et al., 2018; Senyigit, 2019).

From a public health perspective, promoting adequate intake of vitamin K2 through dietary sources like fermented foods, certain dairy products, and supplements could be a feasible strategy to reduce the burden of T2DM. Public health initiatives should emphasize not only glycemic control but also bone health, given the interconnected nature of these systems. Integrating vitamin K2 into broader lifestyle and nutritional interventions aligns with a preventive approach to diabetes, aiming to reduce the incidence and complications associated with this chronic disease (Manna & Kalita, 2017).
