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 and melatonin are both neurotransmitters derived from the essential amino acid tryptophan, found in protein. These brain messengers are important for regulating our sleep cycles and our moods.ryptophan and 5-HTP can be converted into serotonin in the digestive tract but must transported to the brain where it is then synthesized into melatonin. The pineal gland in the brain switches on melatonin synthesis when it detects lower levels of light in the ambient environment.
