Practical Nutritional Strategies to Attenuate Physiological Stress in Adolescent Soccer Players: A Comparative Trial of CoQ10 and Taurine.
In 24 adolescent soccer players, taurine raised IL-10 after repeated match simulations, with no performance or health outcomes tested.
Summary Can taurine supplements reduce stress from intense soccer matches? Show / hide ↓
Researchers gave 24 male soccer players, about 18 years old, taurine, coenzyme Q10, or a placebo, an inactive treatment, for 14 days. They then tested blood after three simulated 90-minute matches. Taurine increased IL-10, an immune signal that can help control inflammation, and both supplements helped preserve CD4 cells, immune cells that help coordinate the body’s defenses. Taurine and coenzyme Q10 also affected other measures of muscle damage, inflammation, and oxidative stress, which is cell damage linked to chemical reactions. The study found no injuries or side effects, but it did not test whether the players performed better or became healthier.
What this means for you: This small study does not show that taurine improves athletic performance, prevents illness, or extends life. Most people can ignore it when deciding whether to buy taurine, especially because the findings involved short-term blood changes in young male athletes.
early evidenceThis randomised, double-blind, placebo-controlled trial assigned 24 male under-19 soccer players, mean age 17.9 years, to placebo, coenzyme Q10, or taurine for 14 days. Each group had eight participants. The coenzyme Q10 dose was 300 mg/day. Taurine was given at 4 g/day plus 4 g before each of three 90-minute soccer-match simulations. Blood samples were taken at baseline, after the first and third simulations, and 24 hours after the third. Outcomes included markers of muscle damage, oxidative stress, inflammation, hormones, and circulating immune cells. Taurine increased IL-10 more than the comparison reported in the abstract: 7.5±0.2 versus 5.7±0.2 pg/mL (p=0.005). Both taurine and coenzyme Q10 preserved CD4 counts relative to placebo, with 795±14 cells/μL for taurine, 790±13 for coenzyme Q10, and 680±15 for placebo. The abstract says taurine was more useful for targeted IL-10 elevation, while coenzyme Q10 was better for several oxidative-stress and muscle-damage markers. No adverse events occurred. This is an acute sports-biomarker study in adolescent males. It does not establish better athletic performance, illness prevention, adult health, or longevity.
Taurine may be preferred for targeted anti-inflammatory support through IL-10 elevation in adolescent soccer players undergoing intensified training.
There were only 8 participants per arm and 14 days of supplementation. The participants were adolescent male athletes, and the outcomes were short-term blood biomarkers around simulated matches rather than performance, clinical, or longevity endpoints.
