Vanadyl sulfate is a supplemental form of vanadium commonly used in sports nutrition. It is believed to exert insulin-like effects by improving glucose and amino acid uptake in muscle cells, potentially aiding muscle growth and recovery.
It became popular among bodybuilders in the 1990s for its proposed benefits in enhancing muscle fullness and vascularity due to improved nutrient partitioning. However, scientific evidence remains limited, and its effects appear to be modest at best.
The compound may influence signaling pathways related to glucose transport, which could benefit glycogen storage post-workout.
Synonyms:
Vanadyl, Vanadium sulfate
Benefits:
- May mimic insulin action
- Potential to improve muscle glycogen uptake
- Supports nutrient delivery to muscles
Sources:
Synthetic compound derived from vanadium; not found naturally in significant dietary quantities.
Observations:
Often included in glucose disposal agent formulas. Should be cycled due to concerns over long-term toxicity. High doses may cause gastrointestinal upset or metallic taste.
