    More about L-Tryptophan:
    It is highly probable that unhealthy eating habits, as well as too much stress and too little time, make that few people are able to meet their body's requirement for L-Tryptophan and therefore really ought to supplement their intake of this vital amino acid. A deficiency in this essential amino acid can lead to erratic mood swings and occasionally even depression, as L-Tryptophan performs important functions in the nervous system as a producer of messengers.

    Great product

    When I take this along with melatonin I fall right to sleep. Take 1 hour before bedtime and it will do wonders.

    Relaxation

    I take this each evening to help me relax and fall asleep. I take it 1 hour before bedtime with calcium and then avoid blue light. I do yoga and read, and then I wind down and fall asleep much easier than in the past.

    As described on bottle

    I was suffering from the "blues," having a hard time sleeping and feeling overall anxious. After taking this for 2 weeks I feel like I'm rejoining the normal half of society. Thank you Zahler for making and selling this wonderful super-supplement.

    Sleep

    I take this every night before going to sleep. I have a hard time "letting go" and this seems to soothe me. I am falling asleep faster than I used to.
