The use of isolated supplements to enhance performance is widespread among athletes. aim this study was increase knowledge about the combined effects caffeine and New Zealand blackcurrant (NZBC) dietary supplements. In study, two subjects each underwent four phases sessions in a double-blind randomized alternating treatment single-case design. After 3-week pre-test phase, supplement combinations placebo/placebo, caffeine/placebo (5 mg/kg), NZBC/placebo (600 mg), caffeine/NZBC mg/kg + 600 mg) were taken weekly tests conducted examine their on relative power (W/kg) during 20-minute time trial bicycle. Data analyzed descriptively using Tau-U calculator from Single Case Research. ergogenic effect confirmed both subjects, with increases 3.3% 6.5%, while positive NZBC only seen one subject (13.4%). combination again increased (2.2% 19.2%), but data showed an additive subject. Further studies are required confirm or refute evidence synergistic these
