Good Pharma's Rest Assured tea contains several ingredients that have been shown to support the body's circadian rhythm, which is responsible for regulating the sleep-wake cycle.

One of the key ingredients is passionflower, which has been shown to have sedative effects and may help improve the quality of sleep. Additionally, passionflower has been found to increase the levels of the neurotransmitter GABA in the brain, which can help to reduce feelings of anxiety and promote relaxation.

Another important ingredient in Rest Assured is jujube seed extract, which has been used in traditional Chinese medicine for centuries to treat sleep disorders. Jujube seed extract has been shown to have a calming effect on the nervous system, and may help to improve sleep quality and duration.

Poria mushroom, which is also included in Rest Assured, has been found to have a calming effect on the mind and body, and may help to reduce stress and anxiety. Lemon balm, another key ingredient in the tea, has been shown to have a relaxing effect on the body and can help to improve sleep quality.

Finally, Rest Assured contains glycine, an amino acid that has been shown to improve sleep quality and promote relaxation. Glycine works by increasing levels of serotonin in the brain, which can help to regulate the sleep-wake cycle and improve sleep quality.

Taken together, the ingredients in Rest Assured work synergistically to support the body's circadian rhythm and promote restful sleep. By incorporating this tea into your bedtime routine, you may be able to improve your sleep quality and wake up feeling more refreshed and energized.
