There are 20 amino acids that living animals need. The essential ones are amino acids that the body cannot create or synthesize itself, instead they must be consumed daily from your diet.
Of these essential amino acids, Tryptophan is found in the lowest quantities in food, yet it is responsible for a huge number of important bodily functions, especially cognition, mood, digestion, behaviour, and the immune system.
Tryptophan is the raw material needed for the body to make Serotonin and Melatonin. Tryptophan passes through the blood brain barrier in small amounts and is used by the pineal gland as needed, and studies show that if the intake of Tryptophan is reduced or limited, synthesis of melatonin is significantly reduced.
Tryptophan significantly improves Stage IV sleep, if taken in the correct quantities, such as what Turkey Sleep provides.
In fact, according to a recent article by the International Journal of Tryptophan Research, “Dietary Tryptophan and its metabolites seem to have the potential to contribute to the therapy of autism, cardiovascular disease, cognitive function, chronic kidney disease, depression, inflammatory bowel disease, multiple sclerosis, sleep, social function, and microbial infections.”
In addition to reduced anxiety levels, tryptophan research has also pointed to positive effects on mood, cognition, and general nervous system health. A recent study also found that running low on tryptophan can increase nausea, headache, and photophobia.
