Latest review conclusion

Foods rich in polyphenols and nitrate provide trivial benefits for endurance exercise performance, although these effects may be food dependent. Highly trained endurance athletes do not appear to benefit from consuming nitrate-rich foods but may benefit from polyphenol consumption. Further research into food sources, dosage and supplementation duration to optimise the ergogenic response to polyphenol consumption is warranted. Further studies should evaluate whether differential sex-based responses to nitrate and polyphenol consumption are attributable to physiological differences or sample siz

“I do supplement a lot of fish oil and vitamin A as retinyl palmitate though. It has really helped my depression, anxiety and ADHD and has enabled me to stop using more serious psychiatric drugs for those things.”
