The prevalence of supplement use varies by gender, reflecting other health issues such as depression and insomnia.
A long-term study found that early childhood stress leads to faster brain maturation in adolescence, while late-life stress has the opposite effect. This accelerated maturation process may limit the brain's ability to adapt to its environment.
