Micronutrients & recovery
Selenium supplementation may offer protective effects against certain cancers (particularly prostate and gastrointestinal) and improve male fertility, but results are complex and depend on baseline status and genotype.
While selenium is important for health, its role in cancer prevention and fertility is complex. Do not self-prescribe high-dose selenium for cancer prevention without medical advice, as the benefits are not guaranteed and depend on your current status and genetics.
