I wouldn't risk taking tryptophan! Unless you want insomnia, depression, lethargy, stomach ache, fever, tachycardia, racing thoughts, nightmares, skin sensations. Just see all the negative reviews on Amazon for it and 5htp. While there are glowing reviews... Who knows if they are real as Amazon is flooded with fake reviews.You think I was right? Is this what serotonin feels like?
I still need to take some tryptophan one of these days, as an experiment. Fernstrom lets us know how serotonin is synthesized from tryptophan. What is amazing is how nearly perfect the line is for the Fernstrom Ratio: W/Σ(T+F+V+L+I) :
'These data indicate that small doses of tryptophan, which do not cause plasma or brain tryptophan concentrations to exceed their normal daily peaks and which do not influence plasma concentrations of other amino acids, produce significant elevations in brain serotonin.' ―Fernstrom
View attachment 7719'If, as seems likely, physiological changes in plasma tryptophan concentrations can cause parallel changes in brain serotonin synthesis, the factors that control plasma tryptophan levels must be considered, for they represent potentially important determinants of the activity of a population of central nervous system neurons.' ―Fernstrom
{The amino acid letter 'P' has actually been designated to represent proline; Fernstom uses this letter to represent phenylalanine↑.}
Fernstrom had also shown that tyrosine lowers prolactin, highly suggesting that it converts to dopamine. The idea that tyrosine hydroxylase is normally saturated appears to be incorrect, although it does appear to be closer to its saturation point than tryptophan hydroxylase.
