A new supplement promising greater endurance capacity and better post-race recovery times is being launched by First Endurance.
OptygenHP was developed with input from elite endurance athletes including Swiss road cyclist Fabian Cancellara and US Ironman champ Jordan Rapp.
Its maker claim it can improve the body's ability to adapt to physical stress by increasing aerobic threshold and reducing lactic acid.
It is already available in the US at around $80 for a month's supply, and will be launching in the UK later this month.
