L-Tryptophan is used by the brain as a precursor to serotonin and melatonin, neurotransmitters that are necessary for normal sleep. In addition to normal sleep, changes in the level of serotonin in the brain can impact mood and satiety. Adequate sleep is crucial for both healthy immune and nervous systems. Zahler's L-Tryptophan is a potent and purified fom which effectively crosses the blood-brain barrier.

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. Zahler's L-Tryptophan contains a robust dose of 500 mg per capsule in a most potent and purified form.

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.


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.
