Why would you claim this? From what I have read 5-Hydroxytryptophan seem like a widely accepted supplement for issues with Serotonin and&#x2F;or depression and mood. The only articles that I have found that say it might not be of use are studies that simply say that 5-HTP is better than placebo but that we can&#x27;t say more yet because of lack of researches.
Edit: and possible heart valves issues if you do not take it correctly<p>&quot;5-Hydroxytryptophan (5-HTP), also known as oxitriptan (INN), is a naturally occurring amino acid and chemical precursor as well as a metabolic intermediate in the biosynthesis of the neurotransmitters serotonin and melatonin from tryptophan.&quot; (<a href="https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;5-Hydroxytryptophan" rel="nofollow">https:&#x2F;&#x2F;en.wikipedia.org&#x2F;wiki&#x2F;5-Hydroxytryptophan</a>)<p>&quot;Preliminary studies indicate that 5-HTP may work as well as certain antidepressant drugs to treat people with mild-to-moderate depression. Like the class of antidepressants known as selective serotonin reuptake inhibitors (SSRIs), which includes fluoxetine (Prozac) and sertraline (Zoloft), 5-HTP increases the levels of serotonin in the brain. One study compared the effects of 5-HTP to fluvoxamine (Luvox) in 63 people and found that those who were given 5-HTP did just as well as those who received Luvox. They also had fewer side effects than the Luvox group. However, these studies were too small to say for sure if 5-HTP works. More research is needed.&quot; (<a href="https:&#x2F;&#x2F;umm.edu&#x2F;health&#x2F;medical&#x2F;altmed&#x2F;supplement&#x2F;5hydroxytryptophan-5htp" rel="nofollow">https:&#x2F;&#x2F;umm.edu&#x2F;health&#x2F;medical&#x2F;altmed&#x2F;supplement&#x2F;5hydroxytry...</a>)<p>etc, etc, burden of proof to you...<p><a href="https:&#x2F;&#x2F;scholar.google.ca&#x2F;scholar?q=5-Hydroxytryptophan&amp;hl=en&amp;as_sdt=0,5" rel="nofollow">https:&#x2F;&#x2F;scholar.google.ca&#x2F;scholar?q=5-Hydroxytryptophan&amp;hl=e...</a>
