Description

Melatonin is a hormone produced mainly by the pineal gland (located in the back of the brain), derived from another hormone, serotonin. Melatonin is extremely important in regulating the body’s biological clock (circadian cycle or sleep-wake cycle) and energy metabolism. Each capsule of 4Sleep contains 1mg of melatonin.

Melatonin helps alleviate the subjective sensation of jet lag. The beneficial effect is obtained with a minimum intake of 0.5 mg, which should be taken shortly before bedtime on the first day of travel and a few days after arrival at the destination¹.

Melatonin helps reduce the time needed to fall asleep. The beneficial effect is obtained with an intake of 1 mg of melatonin shortly before going to sleep¹.

5-HTP, also known as oxitriptan, is the precursor amino acid in the biosynthesis of serotonin, a neurotransmitter that plays a key role in regulating almost all functions of the central nervous system, such as mood, anxiety, stress, appetite, cognition, and sexual behavior. Each capsule of 4Sleep contains 245mg of Griffonia seed extract standardized to 20% 5HTP, which is equivalent to 49mg of 5HTP per capsule (recommended daily allowance).

The 4Sleep Valerian root extract is standardized to 0.8% valerenic Acid. This substance has been shown to have the ability to modulate GABA-A receptors^{6, 7}, producing a suppressive effect on neuronal activity. Valerian helps shorten the time it takes to fall asleep³.

Chamomile flower extract is well known for its relaxing properties, due to the presence of apigenin, a flavonoid polyphenol. According to several studies, apigenin can act as a second-order modulator of GABA-A receptors, that is, a modulator that enhances the effect of endogenous agents that modulate GABA-A receptors⁸. Chamomile helps maintain a healthy sleep⁵. 4Sleep’s chamomile extract is standardized to 1.2% apigenin.
