Dietary supplementation with Lactium and L-theanine alleviates sleep disturbance in adults: a double-blind, randomized, placebo-controlled clinical study

This randomized, placebo-controlled study evaluated the effects of LTC-022, a supplement combining Lactium (a milk protein derivative) and L-theanine (found in green tea), on sleep quality in adults with mild-to-moderate sleep disturbances. After eight weeks, participants using LTC-022 reported improved sleep duration, efficiency, and reduced nighttime awakenings, along with earlier bedtimes compared to the placebo group. Changes in gut microbiota, such as increased beneficial bacteria, were also observed. These results suggest that LTC-022 may enhance sleep quality while positively influencing gut health, emphasizing the gut-brain connection's role in sleep.

To improve sleep, consider dietary sources or supplements containing L-theanine and milk protein derivatives like Lactium, which may enhance sleep quality and duration. These supplements are well-tolerated but work best when combined with healthy sleep habits (e.g., maintaining consistent bedtimes). While findings are promising, they are based on a small, specific population and require further replication in larger studies for broader applicability.
