Saffron for Sleep
A 2025 study found that 30mg of saffron taken daily significantly improved subjective and objective measures of sleep quality in adults 55-85 years old over 4 weeks compared to placebo. Saffron contains crocin and safranal; both of which may enhance non-rapid eye movement (non-REM) sleep. Saffron may also improve symptoms of depression and anxiety. High doses may cause headaches, nausea or other side effects.
