Alpha-lactalbumin in health foods
Alpha-lactalbumin is one of the food proteins with the highest content of the amino acid tryptophan. Tryptophan (Trp) is an essential amino acid that has to be obtained from the diet and cannot be synthesised in the body. Tryptophan is the precursor of serotonin, which is a neurotransmitter and also functions as the precursor to melatonin (hormone involved in the sleep-wake cycle). Serotonin exerts multiple effects and is implicated in the control of the appetite, mood, sleep regulation, cognitive performance and the ability to cope with stress 1.
Alpha-lactalbumin offers a natural way to formulate foods tailored to boost the body’s serotonin production with various effects related to healthy weight and natural well-being.
