TruBeetTM is a unique ingredient providing all-natural nitrates purely derived from beetroot. In a clinical study, supplementation with beetroot extract during metabolically taxing resistance exercise increased plasma nitrite concentrations and strengthened muscle contraction. In addition, competitive athletes who supplemented with beetroot extract increased time to exhaustion during high-intensity exercise, which led to improved stamina and endurance, and reduced oxygen consumption during submaximal exercise. Nitrate supplementation has been clinically shown to support cardiovascular function, possibly by sparing ATP and enhancing muscle kinetics.
Vitamin C is an essential micronutrient that supports the body's defense system by enhancing white blood cell function and activity, and promote interferon levels, antibody responses, and secretion of thymic hormones. Studies show that ascorbic acid may enhance nitric oxide activity and provide support against free radicals.
PurCaf® Green Coffee Bean Extract provides an organic source of caffeine, which may support enhanced performance output and training duration. Based on a systematic and meta-analysis review, the International Society of Sports Nutrition reported that caffeine is an effective ergogenic aid for endurance performance when consumed in moderate doses (3-6 mg/kg). Caffeine may exert its strength and endurance benefits by supporting muscle contraction through calcium ion mobilization and through CNS-mediated mechanisms to promote focus and alertness. Caffeine also inhibits adenosine receptors, which contribute to exercise-induced fatigue.
