90 tabs (Vanilla)


Chewable tablets with caffeine, d-ribose and CoQ10 for sports performance.

Chewable tablets that provide pure caffeine to help increase energy expenditure and improve sports performance. D-ribose assists in energy recovery in muscles post-exercise, while coenzyme Q10 (CoQ10) contributes to energy production throughout the body.

A cup of brewed coffee contains 95-200mg of caffeine. Coffee has long been consumed for the physiological effects of its caffeine content.

Caffeine may stimulate thermogenesis, resulting in the breakdown of fats stored in adipose tissue and, in combination with exercise, may increase the metabolic rate.[1,3-5]

Once metabolised by the liver, caffeine is broken down into three metabolites: paraxanthine (84%), theophylline (4%) and theobromine (12%). Paraxanthine helps break down fat, releasing it into your bloodstream and fuelling your muscles. Theobromine opens up your blood vessels, increasing the flow of oxygen and nutrients to your brain.[6,7]

It is these effects that can attributed to caffeine possibly improving sports performance,[7-9] with absorption into the blood stream occurring 15-30 minutes after oral administration.

Some people experience a “caffeine crash” with a dropoff in energy levels after the caffeine has been used by the body. The actions of D-ribose and CoQ10, and their elimination times in the body, may lessen this crash effect.[10-13]

Ribose is the sugar that begins the metabolic process for the production of adenosine triphosphate (ATP), the major source of energy used by cells of the body for normal function including muscle tissue.

D-ribose may therefore increase the rate of energy recovery in the muscle after exercise by increasing the rate ATP synthesis.[12,13]

CoQ10 plays an indispensable role in the production of ATP, vital for energy in every cell of the body.
