Effects of Rhodiola rosea supplementation on mental performance, physical capacity, and oxidative stress biomarkers in healthy men

PURPOSE: ) supplementation on mental and physical performance, as well as hormonal and oxidative stress biomarkers. METHODS: test. Blood samples were obtained before and after the test to measure the hormonal profile (cortisol, testosterone, and growth hormone), as well as the biomarkers of oxidative stress (lipid hydroperoxides, total antioxidant capacity, and superoxide dismutase) and muscle damage (creatine kinase). RESULTS: ingestion raised plasma total antioxidant capacity. It did not, however, affect other measured parameters. CONCLUSION: extract. Thus, the specific mechanisms responsible for these effects still need to be elucidated.
