Comparative Effects of Vitamin and Mineral Supplements
Pharmacological Research
Resumen
This systematic review and network meta-analysis evaluated the comparative effects of vitamin and mineral supplements on glycemic control and lipid metabolism in type 2 diabetes mellitus (T2DM). The analysis included 170 randomized controlled trials (RCTs) with 14,223 participants. Findings highlight chromium, vitamin K, vanadium, niacin, and vitamin E as the most effective micronutrients for managing T2DM based on various metabolic markers. The study revealed chromium's effectiveness in lowering fasting blood glucose and insulin resistance, while vitamin K significantly reduced glycated hemoglobin A1c and fasting insulin levels. Vanadium excelled in lowering total cholesterol, niacin in improving triglycerides and HDL cholesterol, and vitamin E in reducing LDL cholesterol. These findings suggest that targeted micronutrient supplementation could play a role in comprehensive T2DM management strategies.

Metodología
A systematic search in major databases identified relevant RCTs, followed by network meta-analyses using frequentist random-effects models. The methodology ensured robust synthesis by adhering to PRISMA guidelines and evaluating evidence certainty via the CINeMA tool.
Intervenciones
Interventions included supplementation with chromium, vitamin E, vitamin K, vanadium, and niacin among T2DM patients. Comparisons were made against placebo or no treatment controls to assess impact on glycemic and lipid metabolic outcomes.
Hallazgos Clave
Chromium supplements were most effective in improving fasting glucose and insulin resistance. Vitamin K showed significant reductions in HbA1c and fasting insulin levels. Vanadium lowered total cholesterol, niacin improved triglycerides and HDL cholesterol levels, and vitamin E reduced LDL cholesterol levels.
Comparación con otros Estudios
Findings were consistent with previous studies highlighting the benefits of chromium and vitamin K in glucose regulation. However, this analysis extended knowledge by ranking the comparative effectiveness of various micronutrients across multiple metabolic markers, emphasizing a potential integrative role in T2DM management.
