Busy schedules, electronic gadgets, kids…, the modern average Joe is constantly battling to get a nap. There’s just too much distraction and commitments these days that just falling asleep when you want to can be an uphill task.

And since you ended up on this post, chances are, you’re in that very situation. Good news, you’re not alone. Even better news? There’s a fix.

Well, there are several options you can turn to…, melatonin, vitamins, minerals, herbs… or other compounds meant to help users doze off. There’s one such supplement that has been making waves in the market and garnering some popularity – for good reasons. NooCube Sleep Upgrade is the new talk in town. 

But how is this different from all the other options out there?  Is it worth the price?  Is it safe?  That’s what this review is about!  So stick around as we unpack this new sleep supplement, and look at it to come closer to understanding it. Let’s go!

What Is NooCube Sleep Upgrade?

First things first, let’s look at the nuts and bolts. NooCube packs quite the list of great compounds; magnesium, lemon balm, lavender, and a whole lot more ingredients that we’ll get into in a bit. But what truly gives it some undeniable edge is the availability of supporting research behind it. And of course, remarkable customer service to match. 

Ingredient Quality

It’s time to pop the hood and check what this formula is made of. There’s a lot that goes into scoring the quality of a product’s ingredients. This encompasses the sourcing, the testing, as well as manufacturing processes. 

NooCube Sleep Upgrade has six leading nutrients and botanicals. And while these make up the bulk of this sleep formula, you’ll also find six “extra” compounds. These are pretty much stabilizers, anti-caking, or filler supplements. 

The only thing that takes away from NooCube with the extra compounds is that their amount is a bit high. Not to say they are harmful or anything like that. However, this can be a bit of a deal breaker if you prefer a supplement with fewer binders/stabilizers. 

Take hydroxypropyl methylcellulose, for instance. It might sound like it’s some unsafe stuff, but it’s actually derived from cellulose. And the cellulose itself? This one is sourced from fiber that can be naturally found in foods. Mostly, the likes of beans, nuts, bran, peas, apples, and cabbage. And yes, it is approved by the FDA as well as the European Union as a food/supplement additive.

Even so, the lack of certifications on this supplement is something that needs to be looked into. The manufacturer does have a GMP facility certification though. This ensures responsible manufacturing practices. However, they should consider providing clear information regarding the sourcing of their ingredients. 

All in all, the nutrients and botanicals are undeniably remarkable. The vitamin D, calcium, magnesium, lemon balm, and lavender are quite the selection. Only if NooCube could provide certifications to back up this amazing product.

How To Take NooCube Sleep Upgrade

Now that you know what you get with each purchase, here’s how you should use it the right way. You should take 1-2 capsules about 30 minutes before going to bed. We found that sticking to a same routine (same time every night) was crucial for getting the most out of the supplement. 

Also, keep it consistent, and avoid mixing it with any other sedatives, or even alcohol. This will help avoid any increase in the unwanted side effects.  

A Close Look At Research Studies

NooCube does have rather few primary ingredients. However, they have some sufficient clinical research that helps back up the claim of how their sleep-supporting formula works.

Vitanim D

———————————————————————————————–

Take vitamin D, for instance, is an algae-based, sustainably sourced ingredient. Studies have shown that supplemental vitamin D can be a promising option for improving sleep quality. However, there’s still some conflicting views on how it is beneficial for sleep time and disorders.

So, what makes Vitamin D an effective option? Well, a study in 2022 showed it to be helpful with sleep quality due to various sleep regulation receptors in the brain that it binds to. 

Magnesium Oxide

———————————————————————————————–

How about Magnesium? This one is linked to sleep, although it comes in several forms. However, NooCube includes magnesium oxide and citrate. The citrate is particularly better absorbed by the human body than the oxide. Even then, both are still quite effective at improving sleep quality.

A study conducted on older folks with insomnia showed that supplementing with magnesium oxide helped increase sleep time. And not just that, but it also helps with decreasing sleep onset latency – the time it takes to fall asleep.

Magnesium Citrate

———————————————————————————————–

Magnesium citrate has also proven to be rather potent at improving sleep quality. More specifically, it was found to improve Pittsburg Sleep Quality Index (PSQI) in older people by almost 40%. This involved a questionnaire aimed at assessing subjective sleep quality – focusing on duration, efficiency, quality, latency, and disturbances among other factors.

Calcium Carbonate

———————————————————————————————–

Calcium Carbonate is the other main ingredient in NooCube sleep upgrade, but what part does it play? This one has been associated with helping reduce difficulties associated with falling asleep. It also helps decrease amounts of non-restorative sleep.

Lemon Balm

———————————————————————————————–

Lemon balm, popularly known as Melissa officinalis has also been shown to reduce depression levels. Based on an 8-week supplementation trial, it also helps with anxiety, stress, and sleep disturbances. 

Lavender

———————————————————————————————–

Then there’s Lavender, which has also shown to be effective at promoting a calm feeling and enhancing sleep. The only catch is, most of the research on this one has been done with aromatherapy, lotions, as well as other forms of external use. 

A 2010 study published in Phytomedicine looked at the effects of supplemental lavender oil. Lavender was shown to help reduce anxiety symptoms – almost like anti-anxiety medications such as lorazepam. It has also been shown to improve restlessness, sleep disturbances, as well as well-being and overall quality of life.

Possible Side Effects

While the NooCube offers a wide array of perks, it’s a given that you may experience some side effects. These will vary from person to person, but most of them are minor. Most of the likely side effects that you may experience with NooCube Sleep Upgrade are digestion-based. 

And as it turns out, some of the useful ingredients could turn out to be the ones to watch out for. Magnesium oxide and citrate, for instance, can cause diarrhea in some users. But the good news is, the amounts included in this formula are too negligible to cause any issues. 

Lemon balm, another major ingredient that is likely to cause more significant side effects. Some reports have indicated the potential for dizziness, nausea, digestive issues, wheezing, and even headache.

Again, the amounts used in this formula are way too minute to cause any substantial side effects. It would take up to 2g to bring about these effects, this formula contains around 600mg.

Calcium carbonate is the other ingredient that might have the potential for some side effects, such as bloating or gas. High doses of lavender also have the potential to cause headaches and even constipation.

The only good news is, the amounts found in this formula are way too negligible to cause any serious side effects. Therefore, there’s a chance you’ll hardly experience any downsides – unless you’re extremely sensitive to these compounds.

Our Results & Customer Experience

And now, onto the one aspect that can make or break the deal for any brand, the customer experience. This is where the website experience, customer service and education come into play.

It becomes pretty clear that NooCube isn’t skimping on this one either. Their customer service is quite remarkable. Reaching out to them on their chat system, we got connected with a real human, not some unresponsive bot. And yes, their response was helpful and prompt.

NooCube also offers free shipping, which is a big plus. And the best of all, you get a 60-day guarantee on any of their products. This means a risk-free experience, especially for first-time buyers. 

There’s only one sort of a downside that seems to come across about this website though. The product page might come across as a bit too “salesey” for some. Another kind of a bummer here is the lack of full supplement facts on the website. The company does a great job at providing ingredient breakdown, as well as supporting clinical research.

Their research-backed ingredients are quite outstanding. Then we found customer support, which is not only helpful, but also sufficiently friendly and prompt.
