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.
In other words, if you were to eat foods that actually contain the serotonin molecule, it wouldnât be able to make it to your brain where it is needed to regulate neuron signaling. This means we need to have a supply of certain ingredients that can then be used to synthesize serotonin within the central nervous system.
