1 Foods that are high in protein are often high in lysine. 2  However, too much protein may interfere with tryptophan in the bloodstream, an important precursor to serotonin. 3  Lysine-rich foods include meat, cheese, fish, nuts, eggs, soybeans, spirulina, and fenugreek.erotonin is a neurotransmitter, or chemical in your body that relays messages to your brain. The brain produces serotonin by combining tryptophan hydroxylase and tryptophan to form 5-hydroxytryptamine (i.e., serotonin). Almost 90% of your bodyâs serotonin supply is located in the digestive system and blood platelets.
Serotonin (also called 5-HT) is a neurotransmitter that is produced from tryptophan. Although serotonin is only produced by a small number of neurons (1000's), each of those neurons innervates as many as 500,000 other neurons (3, 12).rolonged use of MDMA results in destruction of serotonergic neurons in the brain (4, 5). Because of the similarities between ecstasy 'trips' and LSD 'trips,' it can be concluded that they must activate a similar pathway, i.e. the serotonergic pathway. Several theories of the mechanism of LSD have been postulated.
