Antioxidant supplements in fertility

Antioxidant and related supplements — including coenzyme Q10 (CoQ10), myo-inositol, and DHEA — are sometimes taken by people trying to conceive or undergoing fertility treatment, often in the hope of improving egg or sperm quality. Research on these supplements is ongoing and results are mixed; some studies suggest possible benefit in specific groups, such as myo-inositol in some people with PCOS, while evidence for others remains limited or inconclusive. None of these supplements is proven to treat infertility, and none should be described or marketed as a 'fertility booster'. These supplements are not free of risk: they can interact with prescribed fertility medicines, may not be appropriate in pregnancy, and their quality and content are not always tightly regulated. Always tell your fertility doctor about every supplement you are taking or considering, including brand names, so they can check for interactions and confirm whether it fits your treatment plan safely. This entry does not provide dosing information; any decision to start, stop, or change a supplement should be made with your treatment team.
