Warm milk is a timeless folk remedy for stress relief, relaxation and sleep. Now, scientists have identified one of the bioactive ingredients in milk responsible for this soothing effect. It's a casein-derived peptide called Lactium, and it's available as a dietary supplement in our Swanson Ultra Women's Anti-Stress Formula. Lactium is a patented, clinically proven approach to stress management, and this peptide fraction within milk protein (casein) is isolated, purified and encapsulated using advanced patented technologies. Clinical research shows that users report feeling calmer, more rested and less stressed within just two weeks of using Lactium daily. It's modern confirmation of grandma's wisdom—safe and much easier to take than warm milk ever was.
