It takes between 20-25 minutes for the product to break down in the digestive system.

You can take this without food or with food. It should not upset your stomach. 

We recommend you do not take O2Boost® within 2 hours of taking any medications, or per the advice of your physician.  

Lactic acid is produced when oxygen levels become low in cells within the areas of the body where metabolism takes place. When the body depletes oxygen that is stored in the muscles, there’s an ‘oxygen debt’ created, that is replenished over time. Endurance Clinical Trials have not yet been studied to determine the delay of onset or relief of lactic acid when taking O2Boost either before or after exercise.
