What it does: In the body, L-tryptophan is converted into serotonin, a neurotransmitter linked to mood and calmness, and further into melatonin, a hormone that regulates sleep and wake cycles.
How it is used: L-tryptophan supplements are popular for supporting healthy sleep, promoting relaxation, managing mild stress, and encouraging balanced mood.
Natural sources and supplement forms: It occurs naturally in protein-rich foods like turkey, chicken, eggs, dairy, nuts, and seeds. Supplement forms typically use purified L-tryptophan produced by fermentation and sold as capsules or powders.
Why it appears in supplement formulas: Its role in the production of serotonin and melatonin makes L-tryptophan valuable in sleep, relaxation, and mood-support formulas.
What to know before use: Because L-tryptophan can increase serotonin, consult a healthcare provider before use if you take antidepressants or any drugs that affect serotonin levels.
L-Tryptophan: Essential Amino Acid Found in Protein-Rich Foods
L-Tryptophan is an essential amino acid that your body cannot make on its own, so it must come from food or supplements. It naturally occurs in protein-rich sources like turkey, eggs, cheese, and seeds. In the body, L-Tryptophan is used to produce important molecules such as serotonin, which plays a key role in mood and overall well-being.
