O2 Gold
AdvoCare
Overview
AdvoCare O2 Gold combines several ingredients marketed for endurance and stress adaptation. While some ingredients like beet extract have evidence for improving muscular performance, the overall product's efficacy for 'maximizing workouts' and 'supporting the body's use of oxygen' is not strongly supported by specific product-level research, as indicated by a study showing no significant short-term effects. The doses of key adaptogens are on the lower side of effective ranges, and the role of inosine for performance is questionable. The inclusion of Hydrolyzed Whey Protein is beneficial for muscle protein synthesis, but its direct contribution to oxygen utilization or acute workout maximization in this context is unclear.
The Good
No major stimulant presence, promoting a smoother energy increase without jitters.
Contains adaptogenic ingredients (Golden Root, Eleuthero) which may support stress adaptation and fatigue reduction over time.
Informed Sport certified, indicating it has been tested for banned substances, which is important for competitive athletes.
The Bad
Several key ingredients, including Beet Extract, Golden Root Extract, and Eleuthero Extract, are likely underdosed compared to clinically effective amounts for performance enhancement.
A commissioned study found no significant short-term effects, suggesting limited or no acute performance benefit.
The ergogenic benefits of Inosine for athletic performance are not well-supported by robust human clinical trials.
