Also known as: Vanadyl Sulfate, Sodium Orthovanadate
Vanadium is an ultra-trace mineral with insulin-mimetic properties observed in animal and cell studies. Human evidence is very limited, and it is not considered an essential nutrient. Supplementation is not recommended for general use.
Vanadium is an ultra-trace element present in minute amounts in the diet, primarily from mushrooms, shellfish, black pepper, and dill. It gained research interest due to its insulin-mimetic effects in animal models of diabetes, where vanadium compounds enhanced glucose uptake and glycogen synthesis independently of insulin. However, human clinical trials have been small, short-term, and yielded modest results with significant gastrointestinal side effects. Doses used in studies (50–100 mg vanadyl sulfate daily) are far above typical dietary intake of 10–30 µg/day and approach levels where toxicity becomes a concern. No RDA, AI, or tolerable upper intake level has been established. Given the limited human evidence and safety concerns, vanadium supplementation is not recommended outside of research settings.
In animal and cell studies, vanadium compounds activate insulin receptor signaling pathways, enhancing glucose uptake in muscle and adipose tissue. Small human trials showed modest blood glucose reductions in type 2 diabetes.
Some animal studies suggest vanadium compounds reduce cholesterol and triglyceride levels, though human data is insufficient to confirm this effect.
With meals to reduce GI side effects
These doses are far above normal dietary intake and carry risk of toxicity. Not recommended without medical supervision and research justification.
