Product Q & A
5-Hydroxytryptophan Vegetarian Capsules by Thorne Research are specifically
designed to enhance the body’s natural process of producing serotonin. This
supplement was made without using any flowing agents that can inhibit
bioavailability, and it includes vitamin B6 for optimal performance.
What you can expect from 5-Hydroxytryptophan:
Increased serotonin levels
Better sleep
Decreased cravings for sugary and sweet foods
Better management of the body’s natural response to stress
What is 5-Hydroxytryptophan? 5-Hydroxytryptophan is an intermediate
metabolite that is made when the body starts the process of converting
L-tryptophan (an essential amino acid) to serotonin. Since serotonin levels are
associated with many essential and behavioral traits, such as mood, sleep,
temperature, pain sensation, aggression and appetite, it is essential to
maintain optimal levels.
Knowing that 5-Hydroxytryptophan (5-HTP) begins the process of converting
L-tryptophan to serotonin, you might wonder why you shouldn’t simply supplement
with L-tryptophan. Actually, supplementing with 5-Hydroxytryptophan is better
for the body because it is more effective at stimulating serotonin production
than supplementing with the amino acid L-tryptophan. 5-HTP cannot be forced into
producing niacin or protein, like L-tryptophan can, so it is completely devoted
to boosting your serotonin levels. By supplementing with 5-HTP, you are
bypassing the stage before L-tryptophan reacts with the enzyme tryptophan
hydroxylase and begins to turn into serotonin. This is extremely beneficial for
serotonin production because this stage is often interrupted by things like
insulin resistance, stress, accelerated age and vitamin deficiencies (such as
folate, vitamin C and iron) before serotonin ever gets produced.
5-HTP is also very well absorbed by the body when taken orally, such as with
these capsules by Thorne Research. In fact, studies have shown that
approximately 70% of the 5-HTP that is taken orally ends up in the bloodstream.
You do not need a transport molecule to be bound to 5-HTP in order for it to
be absorbed in the intestines. Also, other amino acids do not have any impact on
it whatsoever, so you can take it along with meals and not have to worry about
reducing its effectiveness. Another benefit to taking 5-HTP is that it is able
to cross the blood-brain barrier simply and effectively, which means that it can
also increase synthesis of serotonin within the central nervous system.
Benefits of 5-HTP
In various clinical studies, 5-HTP has proven that it can have a positive
impact on sleep, mood, discomfort associated with fatigue and exhaustion, and
cravings for carbohydrates. Many studies on people with less than optimal mood
status have demonstrated a significant improvement in the overall mood of
subjects when they supplemented with 50-30 milligrams of 5-HTP on a daily basis.
The Thorne Research Difference
To further boost the body’s natural serotonin production, Thorne’s 5-HTP
formula contains the active form of the vitamin B5 (pyridoxal 5-phosphate),
which is also a necessary cofactor for the conversion of 5-HTP to serotonin.
Thorne Research creates 5-HTP commercially by extracting it from the seeds of
the African plant Griffonia simplicifolia.

Improves Mood, Helps Sleep
By julie from Oregon, United States on May 31, 2011
I've been using this 5HTP for about 10 months now. It helps me sleep like i did when i was a teenager, plus it improved my mood very quickly. I felt better the next day. I had been on a low dose of Paxil for 9 months prior because of a difficult work situation (which i quit) but wanted off because of the side effects. the only side effect i've had from this is very vivid dreams. My 21 yr old college son was on Celexa for anxiety and depression for about 1 year and also wanted off. He waited 4 months before starting the 5HTP and also felt better immediately. He's now been on it for 6 months and after years of insomnia he's sleeping well at night. He also has some seasonal depression because it is dark & rainy in our area throughout the winters. Now my 19 yr old daughter has begun taking it - pressures of freshman year of college were making it hard for her to sleep and very prone to tears. she also felt better within 2 days. I have nothing but good things to say about it, although after passing it out to several friends, most weren't as thrilled as i was. To me, it's all good.
Pros:
low cost; fewer side effects than prescription drugs; better sleep; better mood
Cons:
i only take 1 capsule a night - taking 2 makes me too sleepy the following morning. some weird dreams.
I would recommend this item to a friend.

Thorne has best product
By KRM from Twin Cities, Minnesota on February 18, 2011
On the advice of my doctor, I am taking 5-HTP for improved sleep. I've tried several other brands and Thorne is hands down the most effective. I will continue to take this brand because of it's high quality. There really is a difference.
After sleeping better, my mood is more even and less anxious. I love being able to get a good night's sleep again.
I would recommend this item to a friend.
amazing results
By sheila nay from southern maine on October 17, 2010
I have been taking hydrosytryptophan for two months now. My dr reccomended them to me for a lifelong anxiety/sleep related problem. I am on meds for sleep and anxiety which worked inthe beginning, but the effectiveness has worn down. I started this product taking one , twice a day on an empty stomach. Increased to 2 - twice a day. I have such a feeling of "well being" now. When I wake at night, I no longer go into "oh my god, i'll never get back to sleep" panic mode. I just go back to sleep! I have never expeerienced this feeling before due to an auto immune and nervous system disorder.
