Overview

This video discusses a recent study on ashwagandha and its effects on exercise performance, comparing it with previous research and its potential benefits for stress and anxiety. It also introduces creatine as a supplement with strong evidence for brain health and performance.

Key takeaways

• A new study found no significant benefit of ashwagandha on aerobic capacity, muscle oxygenation, or blood parameters in healthy men undertaking high-intensity interval training.
• Previous research and meta-analyses had suggested positive effects of ashwagandha on exercise performance, but these studies often had limitations such as small sample sizes and lower quality data.
• Ashwagandha shows more promising evidence for reducing stress and anxiety by potentially lowering cortisol levels, with studies indicating significant improvements in perceived stress and anxiety scores.
• Creatine is highlighted as a supplement with strong evidence for improving brain health, including memory, thinking, attention, and processing speed, with particular benefits observed in older adults and females.
• When choosing ashwagandha supplements, it's important to select brands that have been tested for quality and active compound levels, as many fail to meet standards.
