Brief Summary

Tetraselmis chuii (TetraSOD) is a marine microalgae that has been reported to improve antioxidant responses in human skeletal muscle cells treated with TetraSOD and to improve recovery from muscle damaging exercise in humans supplemented with TetraSOD. However, the effects of TetraSOD supplementation on human skeletal muscle antioxidant gene expression is less clear. This study assessed the effect of short-term TetraSOD supplementation on human skeletal muscle antioxidant gene expression in healthy adults.

Outcome Measures

Primary Outcomes (1)

  • Redox and antioxidant gene expression

    112 genes linked to redox and antioxidant responses are expressed as fold-change gene expression (fold-change) determined using the 2-ΔΔCq method.

    The primary outcome will be assessed at the end of the 14 day placebo and 14 day Tetraselmis chuii supplementation arms
