E-OJ-01 (Oxyjun®), a proprietary, standardized aqueous extract of TA, has been proven to improve cardiac output and thereby lead to better oxygenation capacity and exercise endurance.

This, in turn, averts fatigue and improves physical functioning. Based on the previous studies of E-OJ-01 and the scientific literature available in support of the antioxidant and anti- inflammatory activity of TA bark, in the present study, it is hypothesized that E-OJ-01 will be able to reduce fatigue and improve the cardiorespiratory fitness of the male participants aged between 30 to 60 years.
