5-HTP is the direct metabolic precursor of serotonin and is important for the production of melatonin.

key benefits
• pure HPLC verified supplement
• instant gratification
• reduces carb cravings

who can benefit from 5-HTP?
Those seeking to support serotonin synthesis, especially those who have previously used L-tryptophan for serotonin support without success, may benefit from using 5-HTP.

background reading

5-Hydroxytryptophan (5-HTP) is an amino acid naturally produced by the body from the essential amino acid L-tryptophan. 5-HTP is the immediate precursor to serotonin (5-hydroxytryptamine, 5-HT) and also a precursor to melatonin. In the brain, serotonin and melatonin help regulate sleep, mood, temperature, and appetite. As such, 5-HTP and L-tryptophan are often taken as supplements to support these roles.

Yet, even though L-tryptophan can be transformed into 5-HTP in the body, the two should not be considered interchangeable for supplement use. The conversion of tryptophan to 5-HTP is the rate- limiting step in neurotransmitter production, and L-tryptophan is utilized for a variety of other purposes in the body, leading to less serotonin support than may be assumed. In purified form, human beings have been consuming 5-HTP for over forty years.

5-HTP vs. L-Tryptophan
The body uses L-tryptophan for other metabolic purposes besides serotonin and melatonin production. For example, L-tryptophan is incorporated into proteins and also acts as a precursor in niacin biosynthesis. L-tryptophan absorption in the intestines requires a shared amino acid transporter, meaning that competition with other amino acids from dietary sources can lead to poor L-tryptophan absorption. A similar specific, active transport mechanism is required for L-tryptophan entry into the brain. A number of other physiological and biochemical parameters, such as stress, insulin response, and vitamin B6 levels can conspire to prevent L-tryptophan from becoming serotonin.

In contrast, 5-HTP is not incorporated into proteins and cannot be used to produce niacin. 5-HTP does not require an intestinal transporter for absorption and is absorbed well even in the presence of other amino acids from food, with about 70 percent of that ingested ending up in the bloodstream. Also, since 5-HTP participates in fewer biosynthetic pathways, it is inherently less susceptible to metabolic diversion. The only hindrance of importance for ingested 5-HTP is the activity of peripheral decarboxylase enzymes, which can convert 5-HTP to serotonin before crossing the blood-brain barrier. However, the results observed in 5-HTP research demonstrate that this is not a major concern.

5-HTP Brain Research
Tryptophan supplements have demonstrated benefits for supporting serotonin levels and mood in specific instances, such as with PMS, seasonal changes, and when dieting. Nevertheless, the serving sizes required are often large. The quantities of 5-HTP found to be useful are typically smaller than those of L-tryptophan. Perhaps, more importantly, 5-HTP impacts the levels of other neurotransmitters besides serotonin, such as dopamine and norepinephrine, without acting as a precursor for their synthesis. 5-HTP has been found to support a positive outlook in a number of studies in human beings starting at daily intake levels as low as 50 mg/day.

5-HTP may also be useful in promoting sleep quality by enhancing REM sleep. One study evaluated the rapid eye movements of volunteers after they ingested 200 mg of 5-HTP at 9:15 pm, followed by 400 mg at 11:15 pm. There was a net positive effect on sleep quality, but the large quantities also seemed to increase the incidence of vivid dreams and nightmares in some volunteers. However, another study used 200 mg/day and found positive effects on sleep quality without the concomitant reports of nightmares.

Serotonin & The Second Brain
Some now use the phrase “our second brain” to refer to the impact our digestive tract can have on the entire body. An example of this is the gut-brain axis, which involves extensive bidirectional signaling and feedback between gut and brain. For anyone who has attempted to diet in the past, this may already be understood experientially.

Serotonin plays a significant, yet not completely understood role in the human digestive tract and gut-brain axis. In fact, research demonstrates 5-HTP may even affect leptin, which helps to regulate energy intake and appetite. Such a connection may help explain results in overweight individuals who were able to exert much better control over their diets when taking 5-HTP.

Purity is assured by HPLC. 5-HTP is verified to be free of the "peak X" contaminant.

"Did you hear the news already? Rich Piana died last week!" exclaimed a good friend of ours. "Rich who??" was my response. Then it dawned on me he was speaking of the same person about whom I had been reading the other day and of which I only remembered his face and enormous physique. 
Rich Piana, who had a large group of followers on Youtube and Instagram, as he had a most bizarre amount of muscles and was famous for his grueling workouts. 
Almost immediately everyone assumed he probably died due to overuse of steroids and associated muscle-building products. 

It is not so weird to assume this as the amount of bodybuilders, who haven't lived past 50 years is staggering, because of the ever more dangerous means of attaining a muscular physique that is bigger than that of other competitors in bodybuilding demand more lives every decade. 
The burning desire to create even more muscle mass wins from common sense. When discussing his death people referred a very good documentary called: Bigger, Stronger and Faster. Yet, at a lower level, the sports of recreational bodybuilders, apparently is one of the safest sports around.

While fibromyalgia is regarded as a 'modern disease' it has been around for much longer. The earliest description in the Western literature may be found in the book of Job : "My weary nights are filled with pain as though something were relentlessly gnawing at my bones.".
