There are many herbal supplements marketed for their sleep-promoting effects. Some remedies, such as lemon balm or chamomile tea, are generally harmless, while others can have side effects.
Two of the most popular supplements are:
Melatonin – a naturally occurring hormone that your body produces at night. Melatonin supplements may be effective for short-term use, especially in reducing jet-lag. However, there are potential side-effects, including next-day drowsiness.
Valerian – an herb with mild sedative effects that may help you sleep better. However, the quality of valerian supplements varies widely.
