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 claims to 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 each of the 11 ingredients that it contains is high quality and has been studied, and optimally dosed.
RestAgain claims to boost sleep quality, latency, and duration, while providing other health benefits, such as helping to reduce anxiety, depression, and stress.

Despite all of its selling points, RestAgain is 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 may be worth trying for anyone who is having trouble sleeping, or even those who simply want to improve their sleep quality or sleep wake cycle.
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, melatonin tells your body it’s time to sleep. Once asleep, you can achieve regular REM sleep, which is the most restful type, and maintain a healthy sleep wake cycle.
Taking supplemental melatonin may make it far easier for some people to fall asleep, enjoy a high quality of sleep, and stay asleep, and some studies show it may work within as little as 30 mins.
RestAgain servings each contain 10 mg of melatonin.
Vitamin D – 15 MCG
A fat soluble vitamin, vitamin D is thought to have a number of beneficial effects in the body. Some studies suggest that almost 50% of the US population is deficient in vitamin D, particularly in winter. Some claim that vitamin D can boost mood and relaxation, making it far easier for you to fall asleep.
The recommended daily intake of vitamin D is 400 to 800 IU, and RestAgain contains 15 mcg in every serving, equating to 600 IU.
Vitamin B6 – 1 MG
Vitamin B6 (pyridoxine) is a vitamin made up of 6 compounds that impact over 140 different coenzyme reactions in the human body.
It is especially useful in sleep supplements, with claims that it can enhance neurotransmitter biosynthesis, keep the brain cells healthy and functioning, and encourage REM sleep.
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 ideal, 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 may potentially help reduce fatigue symptoms and encourage better rest and recovery, which is why it is put in sleep supplements like RestAgain.
There are some claims that it may boost metabolism, and prevent brain fog, depression, mood swings, and vascular dementia.
Ashwagandha – 300 MG
Ashwagandha is an 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 may help improve sleep quality and reduce stress and anxiety levels.
RestAgain contains 300 mg of the herb.
5-HTP – 100 MG
The amino acid 5-HTP (5-hydroxytryptophan) is said to boost the brains’ production of the neurotransmitter serotonin.
This may be of particular use in a sleep supplement such as RestAgain, as higher serotonin levels may lead to better sleep quality, and less anxiety, and stress, all of which can have an effect on your sleep pattern.
GABA – 300 MG
The neurotransmitter GABA (gamma-aminobutyric acid) is present in the brain of all adult mammals. It plays a role in the inhibition of certain neurological receptors and may help to determine how easily you get excited or are able to relax.
Clinical studies suggest that people with higher GABA levels might be calmer and experience less anxiety or mental and physical stress, which may be helpful if you want to fall asleep quickly.
L-Theanine – 250 MG
Some claim that having adequate levels of the amino acid l-theanine in your system may help you enjoy a healthy sleep wake cycle, low levels of anxiety and stress, greater relaxation and focus, better brain and immune functions, and enhanced overall health.
All of these possible benefits may help 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.
RestAgain contains the 250 mg dose of l-theanine in each serving.
Valerian Root – 300 MG
Valerian root extract is a popular ingredient in natural sleep aids. It is said to work by helping reduce anxiety and stress levels, which may make it easier for people to relax and fall asleep faster.
RestAgain contains 300 mg of valerian root extract.
Magnesium – 225 MG (125 MG Magnesium Oxide/100 MG Magnesium Glycinate)
The mineral magnesium plays a role in over 600 different reactions in the cells of the human body, some of which relate to sleep quality.
Scientific research suggests that people with high magnesium concentrations in their body may be more likely to enjoy better levels of physical and mental calmness and relaxation, and it may also help soothe muscles and prevent dehydration and cramps, creating ideal sleeping conditions.
The magnesium in RestAgain is also from two of the best sources of magnesium, magnesium glycinate and magnesium oxide.
Calcium – 100 MG
Calcium is a mineral most commonly found in dairy products that is well known to improve the health of your bones and joints. However, some claim that calcium offers a number of other lesser known benefits, including helping your sleep.
