What is Sleep Upgrade?

Sleep Upgrade is a nutritional supplement from NooCube designed to support a healthy night of sleep using natural, non-habit-forming ingredients.

Made in the United States, Sleep Upgrade can help solve one of the biggest problems in many people’s lives: getting a good, productive night of sleep.

The average American only gets 6.5 hours of sleep per night, which is 20% less than the 7 to 9 hours of sleep recommended by experts. Over time, this deficit can contribute to low energy, lack of motivation, increased risk of physical and mental health problems, hormone imbalance, and more.

Some of your body’s most vital processes occur at night – from cell regeneration to hormone production. Sleep Upgrade is designed to support these critical processes by helping you fall asleep faster, get a deep and restful sleep, and stay asleep longer.

Sleep Upgrade Ingredients

Sleep Upgrade contains a blend of natural ingredients. NooCube discloses all ingredients and dosages upfront, making it easy to compare Sleep Upgrade to other sleep supplements sold online today.

Here are all of the ingredients in Sleep Upgrade and how they work:

Lemon Balm Leaf Powder: The largest ingredient in Sleep Upgrade is lemon balm leaf powder. A member of the mint family, lemon balm leaf has a long history of use as a calming herb. It’s been used in traditional medicine for centuries for calmness, relaxation, and anxiety. One study showed lemon balm significantly increased calmness during a lab-induced stress test, while another study found lemon balm lowered insomnia by 42% in people with anxiety and sleep issues.

Lavender 4:1 Extract: The second largest ingredient in Sleep Upgrade is lavender. Each serving contains 125mg of lavender. However, because it’s a 4:1 extract, this dose is equivalent to around 500mg of lavender. A distant cousin of lemon balm, lavender is linked to similar calming properties. Lavender “affects the same part of the brain as many prescription sedatives,” according to NooCube, but in a natural, mellower way with no side effects. Studies also show lavender can improve restlessness and disturbed sleep. For all of these reasons, many people take lavender nightly for sleep and calmness.

Vitamin D3: Sleep Upgrade contains a significant dose of vitamin D3 from Vita-Algae, which is a vegan source of the vitamin. Studies show low levels of vitamin D are linked to poor sleep. In fact, many people with sleep disturbances are found to be deficient in vitamin D. Vitamin D can increase levels of sleepy hormones like melatonin. It can also help regulate circadian rhythm. Today, many supplements source their vitamin D from sheep wool grease, which is a non-vegan source. However, NooCube uses a vegan, algae-derived version of vitamin D3 to keep the supplement free of animal products.

Magnesium: Sleep Upgrade contains a significant dose of magnesium, one of the most important minerals for calmness and anxiety. Studies show magnesium has a calming effect by putting the brakes on overactive brain signals. Other studies have shown magnesium can reduce the time it takes to fall asleep, increase sleep time and sleep quality, and improve overall sleep. NooCube uses a specific version of magnesium called magnesium citrate, which is prized for its bioavailability and absorption.

Calcium: Sleep Upgrade contains calcium in the form of calcium carbonate. Used as a traditional home remedy for sleeplessness for centuries (in the form of a glass of warm milk), calcium has a proven reputation for helping people fall asleep. One study on 4,500+ people found a connection between calcium intake and the time it takes to fall asleep. Another study found people with insomnia tended to have lower calcium levels than people without insomnia.

Unlike many sleep supplements, Sleep Upgrade contains zero melatonin. Although melatonin is a popular over-the-counter sleep aid in the United States, it’s a prescription drug in many countries. Melatonin is a hormone, and daily use of melatonin could lead to hormone imbalance and long-term dependence. Plus, some studies show melatonin doesn’t significantly improve sleep quality or sleep time, yet many people take melatonin regularly. For all of these reasons, NooCube declined to add melatonin to their formula.

Who Should Take Sleep Upgrade?

NooCube markets Sleep Upgrade to anyone who wants to improve their sleep. Some people take Sleep Upgrade to help with jet lag. Others take it to improve next-day energy and motivation.

Here are some of the people who could benefit from taking Sleep Upgrade:

  • Go-getters, including anyone with a lot on their plate who needs a restful night of sleep for next-day performance
  • Shift workers, including anyone working weird hours who struggles to get the rest their body needs
  • Jet setters, including those traveling across multiple time zones who have a disrupted circadian rhythm
  • Night owls who want help getting to bed at a decent time

How to Use Sleep Upgrade

NooCube has designed Sleep Upgrade to be easy for anyone to use. Just take one serving 30 minutes before bed, then begin your usual bedtime routine.

Here’s how to use Sleep Upgrade, according to NooCube:

Step 1) Take Sleep Upgrade 30 minutes before bed.

Scientific Evidence for Sleep Upgrade

NooCube cites dozens of studies to validate the ingredients in Sleep Upgrade and how they work. The supplement also contains large doses of all active ingredients: with four capsules of Sleep Upgrade per serving, you’re taking a significant dose of all active ingredients to help you fall asleep – and enjoy a more restful sleep. We’ll review some of the scientific evidence supporting Sleep Upgrade below.

Lemon balm is the largest ingredient in Sleep Upgrade, and multiple studies have validated the use of the natural ingredient for sleep and restfulness. A 2011 study, for example, found lemon balm (Melissa officinalis) leaf extract helped volunteers with anxiety disorders improve their sleep. Researchers gathered a group of volunteers with anxiety and different levels of insomnia. Some took a placebo, while others took lemon balm. Researchers found volunteers in the lemon balm group had 18% lower anxiety, a 15% improvement in anxiety symptoms, and a 42% lower incidence of insomnia, compared to the placebo. Because of these effects, researchers concluded lemon balm could help with stress, anxiety, sleep, and overall calmness.

A 2019 study, meanwhile, specifically examined the sleep promoting effects of lemon balm. Volunteers took lemon balm extract or a placebo for six weeks. After six weeks, researchers found lemon balm extract was well-tolerated and effective for promoting sleep. Researchers also found lemon balm extract tended to lead to better daytime performance in subjects with moderate sleep disturbances, with participants significantly improving daytime performance from baseline over the six week period.

Magnesium has proven effects on sleep. A 2012 study published in the Journal of Research in Medical Sciences, for example, found magnesium could help with sleep in older adults. Researchers gave magnesium or a placebo to a group of older adults suffering from insomnia. Researchers found magnesium improved subjective measures of insomnia, insomnia severity index (ISI) scores, sleep onset latency, serum cortisol concentration, sleep efficiency, early morning awakening, and more.

Lavender could help improve sleep in patients. A 2015 study found inhaled lavender could improve symptoms of sleep issues, for example. Participants took lavender or a placebo, then measured sleep quality with a Fitbit and sleep dairy. Researchers found those I the lavender group improved sleep quality, helping them wake up feeling more refreshed. Similarly, a large review on lavender found lavender oil could be of small to moderate benefit for improving sleep, according to the results of eight clinical trials. Other studies have connected lavender to benefits on nervous system relaxation.

Overall, Sleep Upgrade contains strong doses of multiple science-backed ingredients to help support a range of effects. By taking Sleep Upgrade daily, you can relax the nervous system, fall asleep faster, and enjoy other effects for a better, more productive sleep.
