Since the performance benefits are immediate, you do not need to start rinsing before your exercise. Rinse regularly throughout your workout, whenever you feel that you need a boost.

Carb-rinsing has a cumulative effect- the more you rinse, and saturate the receptors in the mouth, the greater activation in the brain. There are 4 rinses in each bottle- rinse all of them during your workout!

Yes, absolutely! Rinse is Organic, free of artificial preservatives, colors and flavors, and has no added sugar or sweeteners. It is designed to swallow after rinsing for added hydration benefits, but the choice is yours. The important part is the rinse, so don’t skip that!

Studies show effects of each rinse persists for between 15- 45 mins.

Scientifically, there's no indication this would happen and no maximum amount of rinses recommended.

Over the last decade, studies demonstrate the efficacy of carb-rinsing for improving power output in many sports including cycling, running, strength training, maximum intensity sprinting, stop-and-go sports (e.g. soccer) and combat sports (e.g. fencing). More recent studies reveal that carb-rinsing also bolsters cognitive function (attention, mental focus, reaction speed), so it may be extra beneficial for sports that involve concentration and accuracy (e.g. motor sports, basketball, equestrian).

Studies show improvements ranging from 1.5% to 11.5% for lower body focussed exercise, and up to 17% for upper body based exercise. Evidence indicates up to a 30% increase in motor evoked potentials when isolating specific muscles.
