Vanadium is a trace mineral that may mimic insulin’s effects, potentially influencing glucose metabolism. Some bodybuilders use it during cutting phases for its theoretical nutrient-partitioning benefits, though evidence is limited.
While early research showed promise for blood sugar control, recent studies find minimal impact on athletic performance. The insulin-mimetic effects appear much weaker than actual insulin, making its practical benefits questionable for most athletes.
High doses (over 10mg/day) may cause gastrointestinal distress and green tongue (a harmless but odd side effect).
Synonyms: Vanadyl sulfate
Benefits:
- May support glucose metabolism
- Potential nutrient-partitioning effects
Sources: Shellfish, mushrooms, supplements
Notes: Not a proven performance enhancer
