Natural sleep and relaxation products contain herbal sedatives like valerian, passion flower, chamomile, ashwagandha and rhodiola extracts. These natural substances usually act by relaxing the nervous system and serve as precursors to melatonin, the sleeping hormone. They are natural over-the-counter sleeping pills minus the addictive and other unwanted side effects of pharmaceutical drugs.
Minerals like Magnesium play a role in supporting healthy restorative sleep by increasing levels of GABA, a neurotransmitter that promotes sleep. People with poor sleep have been shown to benefit from supplemental magnesium in research.
