Tryptophan (amino acid) is a precursor of nicotinic acid (vitamin B3) and thus has the character of a provitamin, which undertakes essential functions in carbohydrate, protein and fat metabolism and thus ensures the body's energy supply.

Since tryptophan is converted into the neurotransmitter serotonin, it contributes to regulating emotions and has a particularly positive effect on well-being. It indirectly controls the sleep-wake cycle and promotes the absorption of zinc in the body.

Functions of L-tryptophan

  • Positive effect on sleep quality (regulation of sleep/wake cycle) and well-being/mood as well as productivity
