Several herbs and botanicals are marketed as blends to support athletic performance and exercise recovery. Prominent ingredients in such blends often include Panax ginseng, Rhodiola rosea, Ashwagandha, cordyceps mushrooms, and beetroot. There is a moderate level of scientific evidence supporting the use of some of these botanicals for athletic and exercise-related benefits, though the overall quality and consistency of studies vary.

For instance, Panax ginseng and Rhodiola rosea have been studied for their potential to enhance endurance and reduce fatigue, with some randomized controlled trials and meta-analyses showing modest improvements in physical performance and perceived exertion. Ashwagandha has been associated in several studies with improved strength, VO2 max, and muscle recovery, especially in resistance training contexts. Cordyceps has been explored for its effects on aerobic capacity, with mixed but occasionally positive results in small human trials. Beetroot, high in dietary nitrates, has one of the stronger evidence bases, with multiple studies demonstrating improvements in exercise efficiency and endurance due to enhanced nitric oxide production.

However, while individual botanicals have shown promise, the evidence for proprietary or mixed blends is less robust, as few studies specifically examine their synergistic effects. Most data are derived from studies of single ingredients. Therefore, while some scientific support exists, especially for certain herbs, the strength of evidence for blended products is moderate but not definitive.
