Study Shows Casein Decapeptide Ingredient Reduces Stress, Improves Sleep

Lactium®, an all-natural ingredient made from cow’s milk proteins, has been shown to significantly improve various aspects of sleep disorders in a recent clinical study published in The Open Sleep Journal (Volume 2, 2009). Results indicated improvement in sleep quality after two weeks of supplementation, along with decreases in sleep latency and daytime dysfunction after four weeks of supplementation.

“Sleep is an important biological function that’s necessary for our physical and emotional well-being,” said Mitch Skop, Director of New Product Development for Pharmachem Laboratories Inc, the company that markets Lactium® throughout North and Latin America. “This research has shown that Lactium® can help mitigate the stress that’s often associated with sleep disorders, and get people back on the path to a good night’s sleep.”

The double-blind, placebo controlled study was conducted in Tokyo, Japan on 32 subjects with insomnia. The five-week study used the Japanese version of the Pittsburgh Sleep Quality Index (PSQI-J) to evaluate the following sleep parameters: sleep quality, sleep latency (the length of time it takes a person to fall asleep), sleep duration, habitual sleep efficiency, sleep disturbances, use of sleeping medication, and daytime dysfunction.

Subjects receiving Lactium® experienced significant improvement in the areas of sleep quality, sleep latency and daytime dysfunction. Researchers attributed these improvements to the anti-stress properties of Lactium®.

Skop adds, “This study is strongly significant for the natural products industry because it demonstrates efficacy for the interrelated conditions of stress and poor sleep, whereby each aggravates the other when untended. With this study, Lactium® validates earlier proof that it can improve sleep parameters often associated with stress condition.”

Lactium® is a hydrolysate of milk proteins that contain a bioactive decapeptide with proven relaxing properties. Classified as GRAS, Lactium® has been the subject of several published clinical studies that have shown it to be safe, without side effects, and effective at regulating the major symptoms of stress on the digestive and cardiovascular systems (including blood pressure), as well as enhancing social, emotional, and intellectual capabilities. Lactium® was developed and patented by French firm Ingredia for use in both food supplements, and functional foods and beverages.
