Does Relaxium Sleep Work?

Up to half of adults experience ongoing insomnia.1 To deal with this issue, many prefer natural herbs and products; nearly one out of five people use natural supplements to help them sleep.2

Relaxium Sleep is a popular supplement that contains natural ingredients. The makers of this product guarantee that it will help you sleep more soundly without frequent awakenings. However, Relaxium Sleep users have reported mixed results and some side effects.

How Does Relaxium Sleep Help You Relax and Rest?

Relaxium Sleep contains various ingredients that may help you sleep better:

  • Magnesium — When you don’t have enough of this mineral, you may develop abnormal levels of hormones and other sleep-controlling molecules. Some research shows magnesium supplements could help treat insomnia, although more research is needed.3,4
  • Melatonin — This hormone helps control your sleep-wake cycles. Melatonin supplements can treat sleep disorders like jet lag and delayed sleep phase syndrome, but research is mixed regarding whether it can help with insomnia.5,6
  • L-Tryptophan — Your body uses tryptophan to make serotonin, a neurotransmitter (brain chemical) that helps control sleep. A few small studies show that tryptophan supplements might help you fall asleep quicker and stay asleep longer.7,8
  • Gamma-aminobutyric acid (GABA) — People with low levels of this neurotransmitter are more likely to have insomnia. GABA supplements may shorten the time it takes to fall asleep and increase the total time you spend asleep, although very little research has been done in this area so far.9
  • Valerian — This herb may help increase GABA levels and calm down the brain. Several studies have found that valerian can nearly double your chances of sleeping better.10
  • Ashwagandha — Multiple clinical trials have found that this herb improves various aspects of sleep.11
  • Chamomile — Chamomile is an herb traditionally used to help people fall asleep. However, research has not shown that it makes a difference in insomnia symptoms.12
  • Passionflower — A limited amount of research has found that herbal tea made with passionflower could help boost sleep quality.13

Does Relaxium Sleep Work?

The makers of Relaxium Sleep have reported some impressive results.14 They claim that, compared to a placebo (sugar pill), the supplement can help you:

  • Go to sleep 140% faster
  • Sleep through the night 260% more often
  • Awaken feeling well-rested 69% more often
  • Concentrate more easily on 80% more days

It’s important to know that these results come from a single small clinical trial published by the manufacturer.15 There are a few potential problems with this.

First, Relaxium Sleep wasn’t tested in very many people. In the study, 17 people took a placebo and 20 took the supplement. Additionally, the people who took Relaxium sleep had worse quality sleep to begin with, so the results may have been biased.15

Additionally, researchers got these results by asking participants how they felt about their sleep. When researchers measured participants’ sleep length and quality using a wearable sleep-tracking device, they didn’t find any differences.15

In other words, there isn’t much solid data showing how well Relaxium Sleep works. Reviews on Amazon and Google are mixed, with some people saying the supplement improved their sleep and others saying they didn’t notice any differences.

How to Take Relaxium Sleep

Relaxium Sleep’s bottle says to take two capsules at a time. Take this supplement before bedtime to help make you sleepy.

Relaxium Sleep Safety and Side Effects

We don’t yet have much information about whether Relaxium Sleep is safe for short- or long-term use and what side effects it may cause.

Possible Side Effects

Relaxium researchers said they didn’t find any side effects in their study.15 However, other research has found that some of the supplement’s ingredients cause side effects.

One of Relaxium Sleep’s main ingredients, magnesium, is often used as a laxative (a medication that increases your bowel movements). Therefore, people who take magnesium-containing supplements may experience diarrhea or stomach cramps as well as other side effects like dizziness, itching, nausea, or mood swings.16

Melatonin supplements sometimes lead to mild side effects, including tiredness, nausea, dizziness, and headaches.5

Potential Drug Interactions

It’s not clear whether Relaxium Sleep could interact with other medications you may be using. However, its ingredients are known to interfere with other drugs. For example:

  • Magnesium may change the way the body absorbs a wide variety of drugs, including antibiotics, diabetes medications, and blood pressure medications16
  • Melatonin can interfere with birth control pills, blood thinners, diabetes medications, anti-epileptic medications, or immunosuppressants17
  • Ashwagandha could interact with medications used to treat seizures, muscle spasms, and anxiety18

Researchers don’t yet know what happens when you use Relaxium Sleep while drinking alcohol. However, ingredients like valerian can increase the effects of alcohol, which could harm your health.19

CBT-I: A Long-Term Sleep Solution

Many people choose natural treatments to boost health and improve sleep. However, Relaxium Sleep has not been well studied, and its safety and effectiveness aren’t yet understood.

Cognitive behavioral therapy for insomnia (CBT-I) is a natural, side effect-free insomnia treatment. It involves relearning your sleep habits and addressing issues that are getting in the way of quality sleep. Studies show that CBT-I works as well as or better than sleep medications and has effects that last even after the treatment is done.1
