The research behind Remrise

We selected every Remrise ingredient for specific sleep-promoting, health-enhancing benefits. In tandem, the Chinese and Western herbs in our formulas are proven effective for sleep — without side effects.  


The best Western ingredients

The Western herbs, minerals, and amino acids in your formula are proven to increase your quality of sleep over time.


What it is: 5-Hydroxytryptophan is a crucial amino acid that is naturally occurring in the body and vital to the production of serotonin. Low levels of serotonin correlate to symptoms of anxiety, disrupted sleep, weight gain, and dysregulated mood.  

Why it’s in our formulas: 5HTP helps to produce melatonin (one of the hormones responsible for regulating sleep cycles)  naturally in the brain. Research has shown that Incorporating this amino can be effective in helping you falling asleep faster and staying asleep.

What it is: Gamma-Aminobutyric Acid, often called by its acronym “GABA”, is an amino acid that is produced by the brain. Its primary functions are as an inhibitory neurotransmitter, to block impulses between nerve cells and in doing so, promote mental and muscular relaxation. 

Why it’s in our formulas: It works in the brain by interacting with the neuron receptors, which become less likely to release excitatory neurotransmitters. The result of which include anxiety relief, improved mood and a list of other benefits.  As a supplement this amino acid is often used for sleep, reducing blood pressure, promoting muscle growth, pain relief, burning fat and more. 

Relatively new to the supplement scene, there has not yet been a tremendous amount of research on its efficacy as a supplement relating directly to sleep. But the small body of research is showing promising signs of its benefits.

What it is: This fatty substance, known as a phospholipid, is a key component to the cell membrane.  It’s responsible for cellular building blocks of the brain, produced by the body and also derived from food products like soy, mackerel, tuna, and chicken.

Phosphatidylserine is comprised of fatty acids and amino acids, often associated with optimal brain health, memory and cognition. Traditionally, supplementing the diet with this substance was aimed to prevent or reduce Alzheimer’s disease. 

Why it’s in our formulas: Studies indicate that poor sleep is influenced by unregulated cortisol production and similarly, acute sleep loss impairs functional cortisol. A study focusing on sleep health and development of Alzheimer’s disease, indicated that phoshphatidylserine for a period of 12 weeks reduced cortisol concentrations in the body, with further benefit by regulating the circadian rhythm of salivary cortisol. 

Due to its effects on cortisol regulation in the body, phosphatidylserine is effective in reducing hyperactive cortisol function at night, thereby reducing waking in the middle of the night and related symptoms that cause sleep disruption.




What it is: Magnesium is one of seven essential minerals critical to the body. It plays a central role in maintaining your metabolic health.  In food, magnesium can be found in seeds, nuts, dark leafy greens, whole grains and a bunch of other food sources. 

Your body does not produce magnesium, it has to be ingested. About half of Americans aren’t getting enough magnesium in their diet. 

Why it’s in our formulas: Aside from its role regulating and facilitating a long list of functions, there is a growing body of research demonstrating magnesium’s efficacy in treating sleep. 

Remrise uses Magnesium Glycinate, which plays a key role in affecting the brain’s GABA activity. Additionally, studies have linked magnesium to stress reduction. While this body of research grows in rigor, the research shines favorably on its ability to alleviate anxiety.

What it is: L-tryptophan is an essential amino acid that is crucial to many metabolic functions and plays an important role in mood, behavior and cognition. It is one of the three precursors to the production of melatonin in the brain, essential for healthy sleep. 

Why it’s in our formulas: It has been used in a variety of research settings and clinical trials safely for over 30 years. Unlike many medications it does not hinder waking up in the morning or cognitive functioning. Research shows that L-tryptophan reduces the time it takes to fall asleep and improves stage IV sleep.

 What it is: This amino acid was first discovered by Japanease tea scientists who isolated the substance in tea leaves. Further research uncovered this amino’s ability to promote relaxation by increasing brain chemicals, like seratonin and dopamine. Most importantly, alpha waves, which are present in deep REM sleep are triggered by L-theanine. 

Why it’s in our formulas: In addition to optimizing rest and relaxation, L-theanine will enhance meditation, creativity, and focus, via these alpha wave receptors.

Hops flower


 What it is: Hops is considered a mild sedative that reduces nervous tension and stress.  As a relaxant it reduces overall stress in the body, cools it down when overheated, and decreases inflammation. Classically, it was used as a digestive aid due to its bitter quality, which addresses abdominal discomfort, bloating and gas. 

Why it’s in our formulas: It’s a well known remedy for sleep, as it acts on the neurotransmitter GABA to increase its activity, subsequently decreasing anxiety and calming the mind. In one study, hops flower was shown to be more effective in decreasing the time it takes to fall asleep when blended with Valerian Root. In the study the blended Hops and Valerian performed better than placebo or the individual hops or valerian. 


Calcium Citrate


What it is: Calcium is a crucial mineral for the body, but unfortunately our bodies don’t produce it. Most people know of its importance to bone health, but it also enables our muscles to contract and our hearts to beat. 

If we don’t get enough calcium for the vital role it plays in our bodies, then our bodies body takes it from our bones and over time this can cause them to weaken and break more easily, especially as we age. 

Why it’s in our formulas: Calcium has a direct relationship with our sleep cycles. It helps the brain use tryptophan to produce melatonin to fall asleep. This is why some studies have found that sufficient calcium intake has been associated with decreased difficulty in falling asleep

Studies have also shown that calcium levels in the body are higher during our deepest parts of sleep, thus low levels of calcium can contribute to sleep disturbance, waking easily and poor quality of sleep.

Unlike calcium carbonate, which needs to be taken with food for absorption purpose, calcium citrate can be absorbed on an empty stomach, making it ideal for option for sleep supplementation.


Passion Flower

What it is: Native to the Americas, Passion flower has been used by Native Americans to treat several types of conditions for thousands of years. There are over 500 types of passionflower in the world. Only certain species have medicinal properties. Passiflora incarnata is the type used to treat both insomnia and anxiety. 

Why it’s in our formulas: There is evidence that passionflower may alleviate the symptoms of anxiety disorder, which can commonly cause sleep disturbances.

Passionflower targets the neurotransmitter gamma-aminobutyric acid (GABA) in the brain, which is responsible for inhibiting excitation that leads to restlessness or nervous tension. Through its anti-anxiety and sedative effects, it also gently improves one’s mood and quiets the mind.

Why it’s in our formulas: Studies have confirmed some of the traditional reasons Suan Zao Ren is a therapeutic herb correlate to its sedative effects.

Studies have also shown its efficacy in reducing anxiety and improving sleep quality.


Anemarrhena Rhizome (Zhi Mu)

What it is: Zhi Mu is effective in cooling the body, acting as a deeply nourishing herb in traditional Chinese medicine. 

Why it’s in our formulas: Research suggests that Zhi Mu has the potential to enhance and protect memory impairment by improving the speed of the neurotransmitter acetylcholine (ACh) and the density of its receptors. 

In relation to sleep, acetylcholine plays a key role in REM sleep functions. Therefore the mechanism of action of Zhi Mu indirectly optimizes sleep-wake cycles for optimal sleep.
