Sleepmax is a potent blend of ingredients designed to help provide deep, restful and uninterrupted sleep. A good night's sleep is essential for regenerating energy levels and aiding the recovery process from exercise as well as promoting a healthy mind and body.

Achieving regular uninterrupted, quality sleep is undoubtedly one of the key factors regularly overlooked in the search for improved physical performance.

The quality of your sleep determines the regulation of various growth compounds such as melatonin and cortisol. All of these compounds play vital roles in improving your physical capabilities with their balance and production being seriously hampered through poor sleep. Therefore, the correct sleep patterns should be the priority of anyone who regularly takes part in physical exercise as it can dramatically improve your results.

It is quite clear that deep, regular and uninterrupted sleep is vital for anyone who takes part in physical exercise and who wishes to make the most of the training they perform. Sleepmax is a synergistic blend of natural ingredients that can effectively address poor sleep and is comprised of four main ingredients - Inositol, 5-HTP, L-Glycine and L-Theanine.

Inositol is a vitamin-like substance that is found in many foods such as nuts and fruits. It has been traditionally used as a sleep aid within many clinical settings as it is suggested that it can help combat insomnia. Several studies have also shown Inositol to be extremely effective in preventing depression and anxiety, both huge influences on sleep quality.

5-HTP is a naturally occurring amino acid which is a precursor to the neurotransmitter serotonin, which itself is a precursor to melatonin. 5-HTP helps increase serotonin levels, that in turn has been shown to improve sleep habits. Not only does it appear to reduce the amount of time it takes to fall asleep but it also increases REM, so you sleep deeper and wake up less during the night.

L-Glycine is a non-essential amino acid that acts as an inhibitory neurotransmitter in the central nervous system providing a calming effect on the brain. Glycine has also been shown to induce drowsiness, hasten the onset of sleep and also quicken the onset of deep sleep. Moreover it will do so whilst improving elements of fatigue, alertness and memory the next day.

Theanine has been shown to act as a neurotransmitter in the brain, where it has been shown to generate alpha waves, which amplify a state of relaxation.

Ultimately, Sleepmax helps induce sleep, promotes good quality sleep and also helps maintain sleep right through the night. In doing so, Sleepmax helps the body produce an optimal response to sleep restoring sleep patterns, maximising lean gains, and increasing physical well being.

Unfortunately, we are unable to ship 5 HTP (or products containing 5 HTP) to The Republic of Ireland owing to its status as a prescription medicine in this region.
