What is it?

Nootrobox Yawn is a sleep aid and mental performance supplement. It is designed to help users improve their thinking abilities by helping them get a good night’s sleep.

Their advertising claims that improved sleep can help users think faster, deeper, and more accurately. They say that well rested people have shown improved problem solving skills, and that they have more energy and stamina throughout the day.

The nootropic supplement that has shown the most powerful effects on thinking ability is Memotenz. It is an attention and focus aid that is highly effective for improving information storage and recall.

Nootrobox Yawn Ingredients and Side Effects


Glycine Magnesium
L-Theanine Melatonin

Glycine: The simplest known amino acid. Glycine is used by the body to create proteins, transmit signals to and from the brain, and for improving cerebral blood flow.

There is insufficient data to claim that it has any nootropic benefits. Some manufacturers advertise it as a memory aid, however there is very little scientific proof that these claims are valid.

The main benefits of glycine seem to come from its ability to improve users’ sleep patterns. Studies have shown that users get more rest, and that it is of a higher quality, after taking glycine three hours before their bed time.

Users that are getting better sleep have tested positively for improved cognition, however that is solely due to the extra rest, not because glycine has a direct cognitive effect itself. Glycine will not be effective for those individuals that are looking for short-term energy or study aids, and may even be counter-productive for those uses.

There are few reports of users experiencing side effects due to the consumption of glycine. It is possible that some individuals will experience gastro-intestinal discomfort such as nausea or vomiting, however those cases are rare.

Magnesium: An essential element for proper biological functioning. Magnesium plays a significant role in the formulation of new bone tissue, digestion and elimination, and over 300 other different chemical functions in the body.

While magnesium is broadly useful, it has never shown any specific increases in nootropic abilities such as memory and cognition. It has shown some usefulness in improving the sleep patterns of its users, and again people perform better on cognitive tests when they are well rested, however there are no indications that magnesium directly improves brain function.

Magnesium is safe for most users, however it has a relatively low daily upper limit that should be respected. It is an important chemical for the body, but is not generally a recommended for mental performance supplements.

L-Theanine: Another amino acid compound that is known for its relaxing effects on the nervous system. L-Theanine is often found in green tea and other foods and beverages, and it is thought to help with transmitting nerve impulses to and from the brain.

Because of this, L-Theanine has been studied to see if it may also be useful for enhancing cognition, memory, and attention, however there have been no conclusive findings to support these hypotheses at this time. It may have some adaptogenic effects, helping the brain process accurately when it is under stress, and could have some benefits for the treatment of dementia, however those uses are purely speculatory at this time.

It is still relatively unknown how safe consuming L-Theanine regularly is. There are few reports of short term side effects, and while its long-term effects are relatively unknown, it does not appear to be carcinogenic in any way.

Melatonin: A naturally occurring hormone that the body uses to help regulate sleep cycles. Melatonin is released by the brain in darkness to help prepare the body for falling asleep.

Melatonin is not used for any sort of mental performance, although as previously mentioned, well rested brains tend to perform better. It is not considered a nootropic supplement.

Melatonin has been connected to side effects in some users, and may potentially cause:

  • Headache
  • Fatigue
  • Disorientation
  • Stomach cramps
  • Seizures

Melatonin can also make some conditions worse, especially those related to depression. It is unwise for users to take melatonin before driving or operating heavy machinery.

Nootrobox Yawn Quality of Ingredients

As with any supplement, the effectiveness of Nootrobox Yawn depends largely on what it is being used for. Many customers that purchase it for use as a nootropic supplement will be disappointed, however those that are only expecting it to work as a sleep aid will probably see some degree of results.

Nootrobox Yawn will not be functional as a study aid, energy booster, or cognitive performance enhancer. It does not have the ingredients list to even support the idea that it might, let alone any kind of clinical data that proves it.

If users take it regularly, there is a good chance that they will have longer, deeper sleep sessions that leave them better rested. Well-rested people score better in mental acuity tests in general, especially in regards to alertness, focus, and information retention.

Our team does have some concerns about the fact that Nootrobox Yawn does not post their entire ingredients list, but rather only chooses to highlight these four main ingredients in their promotional materials. It is not known if this is an exhaustive list, or if there are other unlisted additives in their blend as well.

Customer Opinions of  Nootrobox Yawn

Nootrobox Yawn is not sold through any independent retailers, so there are very few reviews of their products from objective sources. There were some reports from previous customers on consumer watchdog sites, including these:

“Total scam; just drink coffee instead.”

“If anything, this stuff does the opposite of what it claims. Spent all day walking around in a fog and I couldn’t focus on anything.”

“Do not fall for their BS! This stuff only made me sleepy, never made me any smarter.”

The most common issue that people had with Nootrobox Yawn was that it did not seem to improve their cognitive function. It seems to have a good track record with making people drowsy, however there were no positive reports of its mental effects.

Conclusion – Does Nootrobox Yawn Work?

Many of the reports from previous customers stated that they got good nights’ sleep after taking Nootrobox Yawn. They said that it worked very similar to how it was advertised, making them start feeling sleepy within 30-60 minutes of taking it.

There were not any positive reports from users that said they felt smarter or more functional after taking the supplement. There were some reports of the opposite, with people claiming that they felt like they were not functioning at their best after taking Nootrobox Yawn.

The ingredients that they mention in their promotional materials are not known as effective nootropic agents, and there may be other unlisted chemicals that are not mentioned at all in their advertising. Our team does not recommend any product unless they know exactly what is in it and it has a good chance of being effective for our readers. As such, our experts did not choose to recommend Nootrobox Yawn.

The nootropic supplement that they have found to be the most effective is Memotenz. Our team was very positive about its ingredients profile, and the reports from previous customers are excellent.

Memotenz is a much more traditional nootropic product, focused on increasing mental energy and functionality immediately in its users, who in general see results within half an hour. Click here to learn more about how Memotenz effects body chemistry and brain power.
