RestAgain is a sleep supplement manufactured by FA Nutra Ltd that has long been popular in the United Kingdom. It has recently seen its popularity explode since releasing in the United States and it is fast becoming one of the best selling and most talked about sleep supplements on the market.
Unlike most sleep supplements, RestAgain is not designed to target just one facet of your sleep wake cycle. Instead, it aims to provide assistance in every area, as it can help you fall asleep quicker, stay asleep longer, feel calmer, recover quicker, and enhance your sleep quality and prevent sleep issues.
Another difference between RestAgain and its competitors is that its formula can actually deliver on all of its claims. Each of the 11 ingredients that it contains is high quality and has been extensively studied, optimally dosed, and conclusively scientifically proven to produce significant results.
This allows it to greatly boost sleep quality, latency, and duration, while optimising your sleep wake cycle and even providing a huge variety of other health benefits as well, such as combatting anxiety, depression, and stress, without putting users at risk of experiencing any unpleasant side effects.
Despite all of its incredible selling points, RestAgain is also still priced in a way that allows it to offer incredible value, particularly if you buy in bulk and take advantage of the offer of a free bottle.
When you put all of this together, it is easy to see that RestAgain is comfortably the very best sleep supplement on the market today. That is why we highly recommend it to anyone who is having trouble sleeping, or even those who simply want to improve their sleep quality or sleep wake cycle.
We actually rated RestAgain as our best over the counter sleep aid for 2023, meaning that you can probably guess that this review is going to be positive.
RestAgain Ingredients The Science Behind The Sleep Aid
Melatonin – 10 MG
Melatonin is the primary sleep hormone produced by the human body. Secreted by the pineal gland in the brain, it is essential to maintain high melatonin levels if you want to achieve regular REM sleep, which is the most restful type, and maintain a healthy sleep wake cycle (1).
Taking supplemental melatonin has been clinically proven to make it far easier for people to fall asleep fast, enjoy a high quality of sleep, and stay asleep for much longer, provided they use at least 5 mg per day. And it’s been shown to work within as little as 30 mins. (2)
With RestAgain servings each containing 10 of melatonin, it is therefore perfectly dosed to help you enjoy the most restful sleep that you possibly can each and every night.
Vitamin D – 15 MCG
A fat soluble vitamin, vitamin d can produce an incredible number of beneficial effects in the human body, from encouraging better protein synthesis to keeping your hormones in check and optimising your body composition, but it’s this hormone regulation that really matters when it comes to sleep. Without adequate vitamin D you naturally find it harder to get quality sleep.
And some studies suggest that almost 50% of the US population is deficient, particularly in winter. Which is why it’s particularly useful sleep supplement such as RestAgain, as it can boost mood and relaxation, making it far easier for you to fall asleep. Improving nutrient absorption and breakdown, recovery time, and energy production, will then make you feel fresher when you wake up too (3).
With the recommended daily intake of vitamin d being 400 to 800 IU and the 15 mcg present in every serving of RestAgain equating to 600 IU, it is therefore perfectly balanced to produce all of these benefits and more.
Vitamin B6 – 1 MG
Vitamin B6 (pyridoxine) is a vitamin made up of 6 compounds that control over 140 different coenzyme reactions in the human body.
It is especially useful in sleep supplements, as it can enhance neurotransmitter biosynthesis, keep the brain cells healthy and functioning, encourage REM sleep, and even boost metabolism and testosterone levels, both of which will further improve your recovery time and sleep quality (4).
As 1.5 mg is said to be the highest daily dose of vitamin b6 that you can safely take, the 1 mg in every serving of RestAgain is again ideal to produce optimal effects without any drawbacks, and even leaves a little room for any additional vitamin b6 you happen to get naturally from your diet.
Vitamin B12 – 3.7 MCG
Vitamin b12 (cobalamin) is a type of vitamin that is vital for the optimal development and function of brain cells, bone marrow, DNA, hormones, nerves, and red blood cells.
It is also extremely good at reducing fatigue symptoms and encouraging better rest and recovery, hence why it is put in sleep supplements like RestAgain.
It is often used to boost metabolism, and prevent Alzheimer’s disease, brain fog, depression, mental decline, mood swings, and vascular dementia. It is also particularly useful in sleep supplements such as RestAgain, as it can both prevent fatigue and its symptoms and enhance rest and recovery (5).
With a minimum daily dosage of 2.4 mcg of vitamin b12 required to produce these effects, the 3.7 mcg in each serving of RestAgain should have a profound effect on your sleep quality.
Ashwagandha – 300 MG
Ashwagandha is a herb extract made from the roots of the winter cherry shrub. Used for many years in ayurvedic medicine, it is said to lower blood sugar levels and boost brain and heart health, focus, memory, muscle growth, strength, fat loss, testosterone production, and athletic performance.
It is also commonly put in sleep supplements such as RestAgain as it has the ability to improve sleep quality and reduce stress and anxiety levels, which will make relaxing and falling asleep far easier (6).
With 120 mg per day being the minimum dose required to be effective and 300 mg being the optimal amount to take in a single dose, the quantity of ashwagandha present in RestAgain is perfect to have the effect on sleep that it is included to provide.
5-HTP – 100 MG
The amino acid 5-HTP (5-hydroxytryptophan) is one of the top ways to aid the brains’ production of the neurotransmitter serotonin, as it can cross the blood brain barrier easier than most compounds.
This allows it to be of particular use in a sleep supplement such as RestAgain, as higher serotonin levels will lead to better sleep quality, relaxation, and fat loss, and less anxiety, depression, stress, and hunger cravings, all of which have an effect on your sleep pattern (7).
GABA – 300 MG
The neurotransmitter GABA (gamma-aminobutyric acid) is present in the brain of all adult mammals. It plays an essential role in the inhibition of certain neurological receptors and will help to determine how easily you get excited or are able to relax.
Clinical studies show that people with higher GABA levels will be much calmer and experience far less anxiety or mental and physical stress, which is vital if you want to fall asleep quickly helping with mild insomnia(8).
L-Theanine – 250 MG
Having adequate levels of the amino acid l-theanine in your system is vital if you want to enjoy a healthy sleep wake cycle, low levels of anxiety and stress, greater relaxation and focus, better brain and immune functions, and greatly enhanced overall health.
All of these benefits will then combine to make falling asleep and achieving a higher quality of sleep once you have far easier, which makes it an ideal inclusion in a sleep supplement like RestAgain (9).
With a minimum intake of 200 mg of l-theanine per day required to produce these effects, the 250 mg dose of l-theanine present in each serving of RestAgain is guaranteed to help you get the very most you can from it.
Valerian Root – 300 MG
Valerian root extract is a popular ingredient in natural sleep aids, as it is both effective and mild. It works by interacting with the GABA neurotransmitters in the brain and helping them reduce anxiety and stress levels, which will make it far easier for people to relax and fall asleep much faster (10).
300 mg is also said to be the optimum dose of valerian root extract required to produce the best results, without any side effects. As this is exactly the quantity of valerian root extract present in RestAgain, it is guaranteed to provide all of the benefits that the compound is capable of producing.
Magnesium – 225 MG (125 MG Magnesium Oxide/100 MG Magnesium Glycinate)
The mineral magnesium is vital in order for over 600 different reactions in the cells of the human body to be able to take place, many of which relate directly to the sleep quality you can experience.
Scientific research has proven that people with high magnesium concentrations in their body are likely to enjoy much better levels of physical and mental calmness and relaxation, and it can also help to soothe the muscles and prevent dehydration and cramps, creating ideal sleeping conditions.
As the magnesium in RestAgain is also from two of the very best sources of magnesium, magnesium glycinate and magnesium oxide, it is able to deliver all of these benefits as efficiently as possible, to guarantee it can improve your ability to fall asleep and then boost sleep quality once you have (11).
Calcium – 100 MG
Calcium is a mineral most commonly found in dairy products that is well known to improve the health of your bones, joints, and heart. However, calcium also offers a number of other lesser known benefits as well, such as reducing oestrogen production and boosting testosterone levels.
It can also make it far easier to fall asleep and enter REM sleep and ensure that you wake up feeling fully restored and refreshed, all of which make it an ideal ingredient in a sleep supplement such as RestAgain (12).
RestAgain Customer Reviews
Due to how new the supplement is, customer reviews of RestAgain are still a little hard to come by. That said, the reviews that we did find virtually all gave it nothing but glowing praise, with many reviewers even claiming that it is by far the best natural sleep aid that they have ever used.
Among the most commonly mentioned benefits of RestAgain that people liked were its ability to aid relaxation, make falling asleep and then staying asleep much easier, ensure that you wake up feeling refreshed, and combat jet lag, while the lack of any side effects of any kind was also very popular.
In fact, the only real negative comments about the effects of the supplement we came across in any RestAgain reviews were from people who said it was so effective that it made them fall into such a deep sleep that they struggled to wake up again.
There were also some people who mentioned that the product was hard to get hold of, although this was mainly in older reviews, as the problem has largely been resolved since RestAgain has expanded their operation.
You put all of this together, and it seems that customers support our scientific findings that RestAgain truly is a well optimised sleep supplement that can treat or prevent virtually any sleep issues and optimise every facet of your sleep wake cycle.
