Does Alpha-Lactalbumin Help With Alpha-lactalbumin is a protein naturally found in breast ...?

Evidence Summary

Alpha-lactalbumin is a protein naturally found in breast milk and cow's milk. It is rich in the amino acid tryptophan, which the body uses to make serotonin and melatonin — chemicals involved in sleep and mood. Clinical trials suggest that taking 40 grams before bed may alter sleep architecture and improve next-morning reaction time in trained individuals who have trouble sleeping, though one study found no benefit in a habitual home environment. It is also widely used in infant formula to better mimic the protein composition of breast milk.
