Evidence supporting the use of: Zinc
For the health condition: Metabolic Syndrome
Synopsis
Source of validity: Scientific
Rating (out of 5): 3
Zinc is an essential trace element involved in numerous metabolic processes, including insulin synthesis, secretion, and signaling, as well as antioxidant defense systems. Scientific interest in zinc for Metabolic Syndrome (MetS) arises from the mineral’s role in glucose metabolism and lipid regulation. Several observational studies have shown that individuals with MetS or its components (such as insulin resistance, dyslipidemia, or hypertension) often have lower serum zinc levels compared to healthy controls. Furthermore, randomized controlled trials (RCTs) and meta-analyses have reported that zinc supplementation can improve glycemic control, reduce fasting blood glucose, and sometimes favorably affect lipid profiles in people with MetS or type 2 diabetes. However, results are somewhat mixed, with some trials showing modest or no benefit, especially in populations without baseline zinc deficiency. Mechanistically, zinc is known to stabilize insulin hexamers, enhance insulin receptor signaling, reduce inflammatory markers, and mitigate oxidative stress, all of which can help address the pathophysiology of MetS. While zinc is not a primary or standalone treatment for MetS, its supplementation may be beneficial as part of a broader nutritional strategy, especially in populations at risk for deficiency. Current evidence justifies cautious support for zinc supplementation in MetS, but larger, longer-term RCTs are needed to establish optimal dosing, duration, and target populations. Clinical guidelines do not yet universally recommend zinc for MetS, but scientific rationale and early clinical evidence provide a moderate level of support.
