Based on your body weight of kg
L-Tryptophan is an essential amino acid that serves as a precursor to serotonin and melatonin, which supports mood regulation, sleep quality, and stress resilience while potentially reducing appetite and carbohydrate cravings through its effects on neurotransmitter balance.
How to Take L-Tryptophan
L-Tryptophan is typically dosed at 500-2000 mg daily, often taken 30-60 minutes before bedtime when used for sleep support, best absorbed on an empty stomach or with a carbohydrate-containing snack but without protein which competes for absorption, and should not be combined with serotonergic medications.
