Glyburide and Vanadium, a caution.
Vanadium has insulin-like effects and has improved glucose metabolism in small human studies. Glyburide is a longer-acting sulfonylurea with a higher hypoglycemia burden than some alternatives, so vanadium may further increase the risk of severe or prolonged low blood sugar.

Caution
What is happening. Vanadium has insulin-like effects and has improved glucose metabolism in small human studies. Glyburide is a longer-acting sulfonylurea with a higher hypoglycemia burden than some alternatives, so vanadium may further increase the risk of severe or prolonged low blood sugar.
Mechanism. Vanadium compounds can mimic insulin signaling and improve insulin sensitivity. Glyburide stimulates endogenous insulin release, and its longer action can make additive glucose lowering more persistent.
Recommendation. Avoid vanadium while taking glyburide unless your prescriber specifically recommends it and plans glucose monitoring. Be especially cautious with kidney disease, older age, missed meals, alcohol, or exercise changes. Seek urgent care for severe, recurrent, or hard-to-correct hypoglycemia.
