What Is Relaxium Sleep?

Relaxium Sleep contains several nutrients and herbs that may help with sleep. The founder is Dr. Eric Ciliberti, a renowned neurologist and sleep expert.

As a Registered Dietitian, I am happy to see that this product is created by a medical professional.

I would be more trusting of someone who has firsthand experience and expertise working with those with sleep problems like Dr. Ciliberti does.

Relaxium Sleep contains 8 core ingredients – some that are said to promote relaxation and also restore the body’s natural sleep cycles.

Dr. Caliberti claims this product is natural, effective, and non-habit forming.

While Relaxium Sleep contains several ingredients that may help with sleep, it is still unknown what the proper dose and combination of ingredients should be.

Everyone responds to sleep aids differently and can therefore experience very different effects.

Additionally, several of the individual ingredients are in lower doses than those shown to be effective in research studies.

I would also be cautious with any other medications that are being taken that can also result in sleepiness. This is a fairly common side effect of other prescription medications.

Combining multiple medications or supplements that have this side effect may result in drowsiness or lethargy.

Evaluation of Ingredients

Relaxium Sleep contains 8 main ingredients:

1. Magnesium (100 mg)

Magnesium is an important mineral that serves many functions in the body.

One small study found that supplementing with magnesium improved sleep quality and insomnia measures at a dose of 500 mg per day.

This supplement only contains 100 mg of magnesium; therefore, it is possible this dose is not high enough to produce an effect.

2. L-Tryptophan (500 mg)

L-tryptophan is an amino acid (protein building block) that helps the body make serotonin and melatonin, two key hormones involved in sleep health.

A small study found that participants who ate higher-tryptophan cereals had improved sleep quality and duration.

While this study shows promise, there are larger, more long-term studies needed to confirm its benefits.

3.Valerest (228.9 mg)

This blend contains a combination of valerian root and hops. Valerian root is an herb that is said to help manage insomnia.

There was one small study where participants took 300 mg of valerian root nightly for 2 weeks.

It was not found to improve sleep. Another large systematic review found valerian root to be safe but not effective in treating insomnia.

Hops are flowers present in beer that are said to have a sedative effect.

In one small 1-week animal study, sleep was improved with 2 mg of hops per day.

Another small human study was conducted, which showed improved nighttime sleep with consuming hops present in non-alcoholic beer.

Additional larger, longer-term studies are needed to confirm the effectiveness of both of these ingredients.

4.Sensoril Ashwagandha (120 mg)

This blend contains an ashwagandha extract. Ashwagandha is an adaptogen, an herb thought to help the body better manage stress.

Ashwagandha has the potential to induce sleep and improve relaxation.

A randomized, double-blinded study showed its potential to reduce insomnia. However, the dose was 600 mg per day, much higher than what is present in Relaxium Sleep.

While adaptogens such as ashwagandha have potential benefits, the dose present in this product may not be adequate.

5. GABA (100 mg)

This supplement contains the neurotransmitter GABA, otherwise known as gamma-aminobutyric acid.

One randomized study showed sleep improvements with taking GABA in a dose of 300 mg twice per day.

However, this supplement only contains 100 mg; therefore, it is questionable if the dose is adequate.

6. Chamomile (75 mg)

Chamomile is an herb that has the potential to promote relaxation and help with sleep.

A 2017 study of elderly adults found that taking chamomile significantly improved sleep.

The dose, however, was 400 mg daily, more than 3 times the amount present in Relaxium Sleep.

While chamomile is generally safe, the dose present may not be enough to produce any benefit.

7. Passionflower (75 mg)

Passionflower is an herb that may help with sleep disturbances.

A small study was conducted that showed short-term sleep improvements in those taking passionflower for 7 days.

There are still more studies needed to determine if the benefits would continue after a 7-day period.

8. Melatonin (5 mg)

Melatonin is a hormone that regulates our natural “sleep-wake” cycle. However, some of us do not produce enough.

There was a large meta-analysis that reviewed 19 studies. Many showed a modest improvement in sleep in those taking melatonin, with a low risk for side effects.

The researchers did note that the effectiveness may be reduced over time the longer you take it.

Still, according to the American Academy of Sleep Medicine, there is not enough evidence on the effectiveness of melatonin for chronic insomnia.

The most common dose recommended is 5–10 mg per day.

Out of all of the ingredients present in this product, I would be most confident to recommend melatonin on its own, given a larger amount of research and its safety profile.

Verdict on Claimed Benefits

Below is our summary of the available evidence for the claimed benefits of Relaxium Sleep based on the available research:

  • Sleep through the nightModerate Evidence
  • Fall asleep fasterModerate Evidence
  • Enhance focus and concentrationLimited Evidence
  • Wake up completely refreshedNo Evidence

Side Effects, Safety, and Dosage

The recommended dose is 2 capsules per day with water.

This product contains several types of ingredients. The most common side effects of ingredients present include sleepiness and nausea, particularly with melatonin.

According to the NIH, passionflower may cause drowsiness, confusion, and uncoordinated movement in some people. However, this was mostly found in much higher doses.

I would be concerned for those taking prescription medications that may also have sleep-inducing side effects, which can exacerbate sleepiness.

Many of the doses of the individual ingredients present are significantly lower than what has been shown to be effective in research studies.

While this is negative, it is a good thing when it comes to its safety profile.

I would recommend speaking to your doctor to review your medical history, medications, and sleep issues before starting this supplement.

Cost and Where to Buy

Relaxium Sleep is sold directly on Relaxium’s website and Amazon. The cost is $45.95 for a 30-day supply from the manufacturer.

The company offers a 10% discount for signing up for their subscribe-and-save program.

I feel the cost is fairly expensive compared to similar sleep aids, which typically run around $15–$25 for a 30-day supply.

If you choose to purchase this product, I’d recommend purchasing from Amazon, as you will pay a lower price and still get the money-back guarantee.

Comparison to Alternatives

There are many sleep aids and specific ingredients on the market, although not many combine several ingredients like Relaxium Sleep.

I would argue that more ingredients are not necessarily better, especially if they’re not in high enough doses to be effective.

Some other ingredients said to improve sleep include L-theanine and ginkgo biloba, which are not present in this product.

The largest amount of research has been done on melatonin and sleep; however, it’s unclear if it would be effective when combined with other ingredients.

I have had clients who take melatonin regularly. Some say it helps with their sleep, but others are not sure if it really does anything.

A potential alternate option for sleep may be in the form of psychotherapy. A treatment known as cognitive behavioral therapy, or CBT-I, has received increased attention for sleep.

CBT-I works to address the underlying root thoughts and behaviors causing poor sleep and helps to replace them with healthier ones, which may actually be more effective than any pill.

The Bottom Line

The main issue with Relaxium Sleep is that it contains a blend of ingredients that have not been studied in combination. There is simply no way to know how they will interact when consumed.

Several of the ingredient doses are also in lower amounts than what has been seen to be effective in the research – such as for magnesium and GABA.

I would not recommend a product such as this, mainly because many doses are lower than what has been shown to be effective in studies.

A Word from Our RD

I would first recommend addressing any underlying root causes of sleep issues.

This can be done with the help of a healthcare team consisting of a registered dietitian, therapist, or psychotherapist to review your habits and medications that could be impacting your sleep.

As a first-line treatment for chronic insomnia, I would suggest CBT-I with a trained psychotherapist to work through the root causes of sleep problems; and additional sleep aids only if recommended by a professional.

Before starting on any new supplement, such as Relaxium Sleep, always consult with your medical provider to determine the benefits and risks.
