Synopsis

Source of validity: Scientific
Rating (out of 5): 2

Milk protein, particularly in the form of alpha-s1 casein hydrolysate, has some scientific evidence supporting its use for insomnia or sleep improvement. The rationale is primarily linked to the presence of bioactive peptides in milk protein that can have anxiolytic (anxiety-reducing) and mild sedative effects, possibly by modulating GABA (gamma-aminobutyric acid) receptors in the brain. Some clinical studies—though generally small and of modest quality—have shown that supplementation with milk protein hydrolysates, especially Lactium® (a commercialized alpha-casozepine product), may reduce sleep latency and improve subjective sleep quality in adults with mild to moderate sleep disturbances. Additionally, milk is a natural source of tryptophan, an amino acid precursor to serotonin and melatonin, both of which are involved in regulating sleep. However, the overall evidence remains limited. Most studies are small, potentially industry-sponsored, and sometimes lack rigorous controls. Systematic reviews acknowledge a possible benefit but consistently call for larger, independent, and better-designed trials to clarify efficacy and mechanisms. Traditional use of warm milk for sleep is widespread, but the scientific basis for isolated milk protein is not yet robust. Current clinical guidelines do not recommend milk protein as a first-line therapy for insomnia.
