Abstract

The ASEA redox cell signaling supplement beverage has been commercially available for the past decade. Despite the market longevity of this supplement, athletic sponsorship, and anecdotal ergogenic claims, there is no independent, peer-reviewed research on its efficacy. The purpose of this study was to determine if ASEA improves aerobic capacity (VO2 max) and/or ventilatory threshold (VT) of physically active subjects. Eleven (6 females, 5 males) young adults (21.9 ± 3.9 yrs) performed 3 VO2 max tests: (a) baseline; (b) after 2 wks of supplementing with ASEA; and (c) after 2 wks of taking a placebo in a cross-over design. The treatment order was randomized and double-blind. The subjects consumed 4 oz∙d-1 (118 mL∙d -1) of the ASEA treatment according to the manufacturer’s recommendations. The subjects’ VO2 max values at baseline (55.0 ± 8.6 mL·kg-1 ·min-1), placebo (53.6 ± 9.1 mL·kg-1 ·min-1), and ASEA (53.7 ± 10.1 mL·kg-1 ·min-1) were not significantly different (P=0.172). Similarly, absolute VO2 max (P=0.436), time to reach VO2 max (P=0.955), VT as a percentage of VO2 max (P=0.678), and maximal heart rate (P=0.410) were not significantly different between trials. Contrary to the manufacturer’s claims, ASEA did not improve the aerobic performance of young, fit adults who supplemented with the product daily for 2 wks.
