Product Notes:

88Herbs designed this formulation of herbs, hormones (in melatonin's case) and vitamin and mineral co-factors as a synergistic combination to give it the best chance of working on each aspect of a good sleep for most people: falling asleep easily; staying asleep throughout the night; enjoying deep REM sleep (without experiencing nightmares); and waking up feeling refreshed (without grogginess).

Notes on Individual Ingredients

Melatonin is the hormone which humans and many animals produce when it gets dark to help get to sleep. There is enough premium grade, animal-derived melatonin in this to help most people fall asleep quickly with just one pill (although two may be required depending on what else is in your system).

L-Theanine is the amino acid contained in green tea which enables it to have a calming effect for many people, despite the caffeine (which is not present in the L-Theanine itself). It appears to increase either the effectiveness or production of GABA (Gamma-Amino-Butyric Acid), which inhibits or limits neural activity in the brain, to induce relaxation, and it does so quite quickly after ingesting it, since it crosses the blood-brain barrier easily.

5-Hydroxy-Tryptophan (5-HTP) is derived from Griffonia seeds (a tropical shrub native to West Africa), and functions as an immediate precursor to producing the neurotransmitter serotonin, which has a positive role in mood. (Many anti-anxiety and anti-depressant formulations attempt to produce more of it or prolong its activity, to help people feel happier or more optimistic.) Although it can be more energizing in higher doses, it can produce a pleasant sleepy feeling in the moderate dose offered here.

Passion Flower is indeed a flower, which has been extensively used and studied as an herbal medicine for improving the quality sleep, fighting anxiety, and relaxing muscles. It also appears to increase GABA activity or production, but not the same way L-Theanine does, so they can complement one another. The type used here has been standardized to contain 20% of its main active ingredient, flavones, compared to 4% or less in many rival products.

L-Tryptophan is an amino acid found in some fish and meat (such as turkey) which can help people stay asleep throughout the night without feeling groggy when they wake up.

Vitamin B3 is a B-complex vitamin with many roles, including helping us relax and get to sleep quickly. Sleep-X uses the niacinamide form of it, which can be absorbed up to times better than some other types.

The mineral Magnesium also helps us relax, both in the mind via the GABA system and in all the muscles of the body, especially when combined with the above ingredients. The form used here, non-buffered magnesium bisglycinate, has the highest absorption available in the natural supplement market.
