Research on DMG (dimethylglycine) goes back more than 30 years where it was observed that DMG improved the racing time of faders. Today, DMG's role in transporting oxygen across the cell to the mitochondria is well un­derstood. DMG can help improve performance, stamina, cardiovascular function, oxygen utilization and muscle recovery. It has also been shown to reduce lactic acid buildup and improve respiratory disease resistance.
