How and when do I use it?

  • A single dose of quinine solution is prepared by mixing 0.02 g of Quinine Hydrochloride Dihydrate in 25 ml of deionised water (or 0.08 g per 100ml of deionised water). Such a solution is considered safe to use. However, quinine powder (Quinine Hydrochloride Dihydrate) is considered hazardous and requires careful handling.
  • It is necessary to swirl the quinine solution in the mouth and then swallow it to achieve a beneficial effect.11
  • Such a protocol (10-20 seconds prior to the sprint) has been found to improve a maximal 30 second cycling effort8 and the initial 80 seconds of a 3 to 4-minute cycling time-trial.9
  • However, quinine ingestion during the last 90 second of a 4-minute maximal cycling effort has failed to improve performance.12
  • Ingesting the directed single dose of quinine solution triggers an extremely bitter sensation in the mouth, which can be counteracted, postevent and after benefitting from the ergogenic effect of the tastant, by ingesting a salty snack (e.g. Salt and Balsamic vinegar flavoured rice cakes) or equivalent.
