The Science Of Sleep: Best Supplements For Sleep And Restful Nights

September 11, 2023

Sleep is an essential function that plays a vital role in metabolic regulation, cellular repair, cognitive function, emotional stability, and even immunological response.

A good night’s sleep enables the body to repair tissues, synthesize proteins, and consolidate memories, helping you to function optimally during waking hours. Conversely, poor sleep can contribute to a host of problems including increased stress, impaired judgment, a weakened immune system, and heightened vulnerability to chronic conditions.

Today, more and more people are gravitating toward a natural approach to regulating sleep cycles, avoiding the use of chemical aids whenever possible. Herbal alternatives offer a natural way that can help to regulate sleep patterns, improve sleep quality, and help individuals fall asleep more easily. This article uncovers the range of supplements that help you sleep better. Next up, we describe their benefits.

Among herbs that help with sleep, ashwagandha has a special place. As an adaptogen, this plant helps the body adapt to various types of stress, both physical and mental. By fostering a more balanced response to stressors, an ashwagandha supplement can help you maintain a more consistent, positive outlook, even in challenging situations. When your body is relaxed and not under stress, it falls asleep better and faster. By making the body more resilient to stress, ashwagandha can improve your sleep.

Furthermore, supplements for better sleep with ashwagandha have an impact on gamma-aminobutyric acid (GABA). This is an inhibitory neurotransmitter that calms nervous activity, which is crucial for the ability to fall asleep and stay asleep. 


Though mullein is traditionally used in managing respiratory issues, it also possesses mild sedative effects. With its calming and soothing properties, this herb helps prepare the body and mind for sleep. 

Mullein-infused supplements to increase deep sleep also exert muscle relaxant properties. Muscle tension can make it difficult to drift off or can lead to disrupted sleep. Thus, mullein can be another natural way to promote restful slumber.

Serotonin, dopamine, and norepinephrine are neurotransmitters which are crucial for mood regulation and, by extension, sleep. L-Methylfolate, a bioactive form of vitamin B9 (folic acid), helps boost the production of these brain chemicals, notably, serotonin. By doing so, this natural compound regulates sleep patterns, preventing common sleep disturbances like insomnia.

Folate is also involved in the conversion of carbohydrates into glucose, the body’s primary energy source. Proper energy metabolism helps with fatigue and tiredness, helping the body to establish a healthier sleep-wake cycle.


The primary benefit of 5-HTP is its role as a precursor to serotonin. It is a neurotransmitter that has various functions, including the regulation of mood and sleep-wake cycles. Furthermore, serotonin serves as a precursor to melatonin, the hormone directly responsible for sleep regulation. Melatonin helps to control the body’s sleep-wake cycle, signaling to the body when it’s time to wind down for the night. Increased levels of serotonin due to 5-HTP supplementation can lead to increased melatonin production, aiding in faster sleep onset and more restful nights.


Magnesium helps to activate the parasympathetic nervous system, the system responsible for inducing calm and relaxation. It does this by binding to and stimulating GABA receptors. GABA (gamma-aminobutyric acid) is the neurotransmitter responsible for inhibiting nerve activity, allowing the mind and body to relax. In this way, magnesium can set the stage for sleep by reducing neural excitability.

Beyond this, magnesium helps regulate calcium channels in cells, allowing for the controlled contraction and relaxation of muscle fibers. This action can help alleviate symptoms of restless leg syndrome and muscle cramps, both of which can interfere with sleep.

Valerian Root

Valerian root stands as a potent herb among other herbs to help you sleep more peacefully. This botanical  is often used for its anxiolytic (anxiety-reducing) effects. Anxiety and stress are common barriers to falling asleep and staying asleep. When we are under stress, we become nervous, our thoughts are spinning circles in our minds, not letting us relax and prepare for bedtime. By reducing anxiety and inducing a state of calmness, valerian root can help soothe your irritated nerves and mind, preparing your body for a restful slumber.

Sleep is not just a time for rest – it’s a critical component of good health that regulates various bodily functions, from cellular repair to hormone balance. Lack of adequate sleep can wreak havoc on both your physical and mental health, leading to a closed loop that can be difficult to break free from.

The herbal supplements discussed in this article offer a gentle and holistic approach to sleep regulation. Whether it’s the calming effects of valerian root, the neurotransmitter support from 5-HTP, or the muscle-relaxing properties of magnesium, these natural supplements show promising results for setting stable sleep patterns.
