Origin & History
Tryptophan is an essential amino acid renowned for its role in the synthesis of serotonin and melatonin, key molecules that regulate mood, sleep, and emotional balance. Found in protein-rich foods such as turkey, dairy, eggs, seeds, and legumes, tryptophan is critical for neurological function, appetite regulation, and circadian rhythm support. It also plays a secondary role in pain modulation and cognitive clarity.

Frequently Asked Questions
What is Tryptophan?
Tryptophan is an essential amino acid that serves as the precursor to serotonin, a neurotransmitter that regulates mood, and melatonin, the hormone that controls your sleep-wake cycle. Your body cannot make it, so you must obtain it from your diet.
Is it safe to take Tryptophan with antidepressants?
No, it is not recommended. Combining Tryptophan with serotonergic antidepressants like SSRIs can dangerously increase serotonin levels, leading to a serious condition called serotonin syndrome. Always consult your doctor before use.
Will eating turkey make me sleepy?
While turkey contains tryptophan, the idea that it alone causes post-meal drowsiness is largely a myth. The sleepiness is more likely caused by the large, carbohydrate-rich meal typically eaten with it, which helps tryptophan cross into the brain.
