Montiff’s L-Tryptophan contains 500mg of the highest quality USP L-Tryptophan available for professional use. L-Tryptophan is the precursor to Serotonin, a neurotransmitter in the brain which is deficient in depression and naturally enhances sleep

Tryptophan, an essential amino acid, is the precursor to Serotonin, which is a necessary neurotransmitter responsible for transmitting nerve impulses in the brain, and inducing sleep and tranquility

Tryptophan is very important for biochemical balance of the brain, and is very helpful for those with sleep deprivation, anxiety and mood enhancement due to low Serotonin levels. It also helps to biochemically balance the brain in those whose Serotonin levels are low because of chemical addictions. It has also been effective in appetite control, increasing pain tolerance and assisting those with jet lag.

Sleeping again

My husband and I try to never run out of L-Tryptophan it has helped us both sleep so much better.

Sleep assured

I have had overwhelming anxiety during COVID19 lockdown. It lasted two weeks straight and I was very anxious at bedtime and frequently woke up during the night, scared and anxious. With the L-Tryptophan, I was able to fall asleep calmly and stay asleep throughout the night. I had even been to the doctor for a prescription but didn't like the way it made me feel. Glad I thought of Nutritional Weight and Wellness to help me!
