NutriSleep: Science Natural Supplements Sleep Aid Review

NutriSleep by Science Natural Supplements is a natural sleep aid using organic ingredients in a proprietary blend to help users fall asleep fast and stay asleep for wellness benefits to wake up ready.

Full Disclosure

For consumers that want to look and feel their best, there really is nothing like a good night's sleep. Sleep issues have been associated with worsening signs of aging, immune deficiency, depression, and a number of additional issues. Six to eight hours of quality, deep sleep is necessary, allowing the brain to rest and the body to prepare itself for the energy expulsion of the coming day.

While physicians can prescribe consumers with medicine to help them improve their sleep and reap the benefits that come with a rejuvenated sleep schedule, many of these medications are expensive, and some even come with a host of unwanted negative side effects. Supplements present consumers with a unique alternative to traditional medication plans; some sleep supplements can secure users a good night's cheap for a fair price and without the side effects of traditional medicine.

NutriSleep is a nutritional supplement that claims to help you fall asleep faster and stay asleep longer. The supplement contains melatonin and valerian. The manufacturer claims that it “improves sleep quality guaranteed,” giving users “healthy sleep and relaxation.”

While consumers should still consult their healthcare provider with specific questions before taking this or any nutritional supplement, this review will consolidate information to provide readers with a solid basis of understanding concerning NutriSleep and the company behind it.


What is NutriSleep?

NutriSleep is a nutritional supplement made by Science Natural Supplements. Currently, the supplement is exclusively sold through the official product website.

Science Natural Supplements claims that, by taking their formula daily, you can reduce stress and anxiety, enjoy healthier sleep patterns, prolong sleep intervals, and boost vitality and focus.

The company also emphasizes the fact that their formula is safe, natural, and drug-free. Instead of using pharmaceutical medications to encourage sleep, NutriSleep uses natural ingredients like melatonin and valerian to guarantee their customers a healthy, natural sleep.

Each bottle of NutriSleep (60 capsules per bottle) is priced at $30 to $40 on the product website, with stacking discounts for users that buy multiple bottles of the supplement at one time.

Science Natural Supplements has previously marketed this supplement as “NutriSleep Rx.” Today, the formula is identical to NutriSleep Rx, although the supplement is now known simply as NutriSleep.

NutriSleep Features and Benefits

NutriSleep claims its formula is linked with a variety of health benefits. Of course, it’s no secret that a good night’s sleep is linked to good health.

But Science Natural Supplements claims that their product is uniquely beneficial, even among other sleep aides. The company claims that users of NutriSleep can:

  • Reduce stress and anxiety
  • Regularize healthy sleep patterns
  • Prolong sleep intervals
  • Boost vitality and focus
  • Reduce symptoms of digestive disorders
  • Increase libido
  • Reduce the risk of obesity
  • Reduce risk of heart disease
  • Treat insomnia
  • Enhance mental clarity, focus, and energy levels

Getting a good night’s sleep is obviously healthy for you. However, does NutriSleep actually encourage a good night’s sleep? Or is this another over-hyped supplement backed by no science? Let’s take a closer look at how NutriSleep works.

How Does NutriSleep Work?

NutriSleep contains over a dozen ingredients, most of which are packaged into a “Sleep Formula Proprietary Blend” (1071mg). This blend contains L-tryptophan, valerian, goji, chamomile, and lemon balm, and several other ingredients.

You take two capsules before bed to encourage a healthy, restful sleep. Science Natural Supplements recommends taking the supplement 20 to 30 minutes before bedtime with 8oz of water. The steps for use include:

Step 1) Take two capsules of NutriSleep 20 to 30 minutes before bed with a glass of water

Step 2) Fall asleep more quickly and naturally stay asleep for 6 to 8 hours

Step 3) Wake up feeling refreshed with more energy

That all sounds good – but does NutriSleep actually work as advertised?

Scientific Evidence for NutriSleep

Let’s start with L-tryptophan, which is an essential amino acid that makes you fall asleep. You’ve probably heard about how tryptophan in Thanksgiving turkey causes people to fall asleep. Does science back up this effect?

Here’s what WebMD about L-tryptophan:

“People use L-tryptophan for severe PMS symptoms (premenstrual dysphoric disorder or PMDD) and quitting smoking. It is also used for athletic performance, depression, insomnia, and many other conditions, but there is no good scientific evidence to support many of these uses.”

Some studies have shown that L-tryptophan reduces the amount of time it takes to fall asleep. Other studies have shown that L-tryptophan increases mood in healthy people with sleep problems. However, there haven’t been many widespread human studies on L-tryptophan verifying these effects.

We do know, however, that your body needs L-tryptophan to make serotonin and melatonin. In fact, many believe this is why L-tryptophan encourages sleepiness. Tryptophan can be converted into a molecule called 5-HTP, which is used to make serotonin and melatonin. Serotonin affects your mood, while melatonin influences the sleep-wake cycle.

We also know that low levels of L-tryptophan are associated with mood disorders. People who are stressed or anxious tend to have low levels of L-tryptophan.

Next, let’s talk about another major nutrient in NutriSleep: melatonin. Melatonin influences the sleep-wake cycle of the body. It also impacts the metabolism of nutrients, your immune system, and other body functions.

Approximately 3 million Americans use melatonin supplements for sleep aids, according to a survey by the CDC. Melatonin supplements seem to impact sleep in some people but not others.

First, your body produces melatonin naturally. Melatonin on its own does not make you sleep, but as melatonin levels rise in the evening, it puts you into a state of quiet wakefulness that helps promote sleep. Most people’s bodies produce enough melatonin for sleep on their own, although some people supplement natural melatonin production with a supplement.

Studies have shown that taking 1mg to 3mg of melatonin two hours before bedtime can help you fall asleep. It’s unclear how much melatonin is included in NutriSleep.

Valerian is the second biggest ingredient in NutriSleep. Can valerian help you fall asleep? Some people call valerian root “nature’s Valium”, and the herb has been used since ancient times to promote tranquility.

Valerian root contains a number of compounds that could help you fall asleep. It interacts with GABA, for example, a chemical messenger that regulates nerve impulses in your brain and nervous system. Low GABA levels are linked with poor quality sleep.

Multiple studies have also shown that valerian root can help you relax. In this study, for example, adults received valerian root or a placebo before taking a challenging mental test. Researchers found that valerian minimized anxiety at doses of 600mg to 1,200mg, although it actually increased anxiety at a dose of 1,800mg.

This study, meanwhile, showed that valerian root can reduce the amount of time it takes to fall asleep. Several other studies have shown that valerian can improve sleep quality and quantity.

Chamomile is another major ingredient in NutriSleep. Chamomile is traditionally used as a relaxation agent or sleep inducer. Chamomile tea is a popular mild tranquilizer, for example. Researchers believe chamomile’s calming effects are linked to an antioxidant called apigenin, which binds to receptors in your brain, decreasing anxiety and initiating sleep.

Just like melatonin, chamomile helps some people sleep – but not others. This study of 60 nursing home residents found that those taking 400mg of chamomile extract per day had significantly better sleep quality than a placebo. A separate study where people with chronic insomnia received 270mg of chamomile twice per day for 28 days revealed no significant benefits.

Goji berry is the third-listed ingredient in NutriSleep, although it has not been extensively studied for its connection to sleep. However, some studies have shown that the magnesium and thiamine in goji berry is connected to improved sleep. There’s 90mg of magnesium (23% of your DV) in NutriSleep.

It’s also important to note that Science Natural Supplements does not disclose the individual dosages of any ingredients in this formula. We know there’s 1071mg of the NutriSleep Sleep Formula Proprietary Blend, for example, but we don’t know the individual dosage of any ingredient in that formula.

NutriSleep Ingredients

NutriSleep hides most of its ingredient dosages behind a proprietary formula. Here’s what the ingredient label looks like:

NutriSleep Supplement Facts

We don’t know the dosage of specific ingredients like tryptophan, valerian, chamomile, or melatonin, all of which are research-backed sleep aids. However, since there’s 1071mg of the proprietary formula in total, we assume the supplement has decent dosages of each ingredient.

NutriSleep Pricing

NutriSleep is priced between $30 and $40 per bottle, depending on how many bottles you order. Purchasing options include:

  • 1 Bottle: $39 + $19.99 Shipping
  • 3 Bottles: $105 + $19.99 Shipping
  • 6 Bottles: $174 + $19.99 Shipping

NutriSleep Refund Policy

NutriSleep has a 100% money back guarantee. You can request a refund at any point within 180 days.

Here’s how the company explains its refund policy:

“After you order any of our products today, if you are not completely satisfied, simply contact me within the next half a year and send it back in any condition and I will see that you get a complete refund with no questions asked, no hassle whatsoever.”

It’s unclear if you receive a refund on shipping costs. NutriSleep has extremely high shipping costs ($20). Some manufacturers use high shipping costs to cover the cost of a refund, which is a manipulative tactic consumers need to look out for.

Final Word

NutriSleep is a sleep aid supplement that contains about 1,000mg of herbal extracts and amino acids, including melatonin, chamomile, and L-tryptophan. Studies have shown that these ingredients can enhance sleep quality in many people, although they may not work for everyone.

If you want to improve the quality, duration, and length of your sleep, and if you want to fall asleep more easily, then NutriSleep may be the right choice for you. However, NutriSleep may not work for everyone, and it’s significantly more expensive than many other sleep aids available today.
