f Source Naturals L-Tryptophan 500 mg Reviews and Information

L-Tryptophan 500 mg

The essential amino acid L-Tryptophan helps support relaxation, restful sleep, and feeling better. It plays a part in the synthesis of both melatonin and serotonin, hormones involved with mood and stress response. L-Tryptophan also supports immune functions because it is the body's precursor to the kynurenines that regulate immunity. If needed, L-Tryptophan converts to niacin in the body, which supports circulation, a healthy nervous system, the metabolism of food, and the production of hydrochloric acid for the digestive system. Source Naturals L-TRYPOTOPHAN is extremely pure and is regularly tested to ensure the highest standards of quality.

Do not touch these, or anything Source Naturals for that matter - I have been very ill for 15 months after taking two Source Naturals L-Tryptophan capsules. I have all the symptoms of EMS, a serious disease caused by contaminated L-Tryptophan. Several more people in the States are also ill after consuming L-Tryptophan. The bottle states that Source Naturals L-Tryptophan is extremely pure and regularly tested - absolute rubbish, the truth is that Source Naturals buy in bulk the cheapest L-Tryptophan from China. Source Naturals were litigated in the 1980s as suppliers of contaminated Tryptophan which caused an outbreak of EMS, they are back again putting into capsules the poorest quality cheapest junk they can get their hands on to make the biggest profits at the potential expense of public health. Do the world a favour and never buy anything with the Source Naturals label on the bottle.

Build Serotonin
by Sherri Jacobs, ND, CNS

I use Tryptophan frequently in my practice. It helps build healthy levels of the calming neurotransmitter, serotonin. It is extremely helpful for promoting restful sleep and balancing mood.

Great sleep aid
by Jaime

If you've ever felt sleepy after eating turkey, you'll understand what a wonderful sleep aid this product can be. It's not a traditional sleep aid, but it works to help you relax and fall asleep more easily without feeling groggy when you wake up. It's a fabulous (and natural) way to help yourself sleep.

One of the best kept secrets in supplemental health.
by Kevin G

L-Tryptophan 500 is wonderful taken as a sleep aid or as a serotonin regulator. Long term use of this product has contributed to a considerable increase in my mood and sleeping patterns.
