Synopsis

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

Lactium is a proprietary bioactive decapeptide derived from casein, the primary protein in milk. Its use for insomnia is justified by some scientific evidence, though the overall strength and consistency of this evidence is limited, meriting a rating of 2 out of 5. Clinical studies suggest that Lactium may promote relaxation and improve sleep quality by acting on the gamma-aminobutyric acid (GABA) receptors in the brain, which are involved in regulating anxiety and the sleep-wake cycle. Several small-scale, randomized controlled trials and open-label studies have shown that supplementation with Lactium can reduce stress-related symptoms and may improve sleep parameters such as sleep latency and sleep efficiency in adults suffering from mild to moderate insomnia or stress-induced sleep disturbances.

However, most of these studies have limitations, including small sample sizes, short durations, and sometimes funding or sponsorship by manufacturers. Meta-analyses and independent reviews generally agree that while there is some promise, the evidence is not robust enough to unequivocally recommend Lactium as a primary or standalone treatment for insomnia. It is often marketed as a natural alternative for those seeking non-pharmaceutical interventions. In summary, Lactium casein decapeptide has some scientific basis for its use to support insomnia, but more rigorous, large-scale studies are needed to firmly establish its efficacy and safety profile.
