- Brief summaryEffect of milk containing Lactium® on subjective sleep parameters.

The quality of sleep is intrinsically linked to quality of life. According to CBS thirty eight percent of the middle-aged women in the study (> 45 y) responded ‘yes’ to the question ‘Have you had sleeping problems in the past 14 days?’ Lactium® is a protein hydrolysate derived from enzymatic treatment of milk (á-S1) casein and has prooven anti-stress effects.

The objective of the study is to study the effects of milk containing Lactium® on sleep in 200 adults with minor sleeping problems.

The study design is a randomized, placebo controlled, double blind intervention study, with parallel groups. A total of 200 subjects will be randomised to one of the two treatments: reference (normal semi-skimmed) milk and semi-skimmed milk with Lactium. Each subject will use the study milk during 2 weeks, half-an-hour before going to sleep.

Primary outcome measures:
Daily questionnaires: Sleepiness (Scored by the Stanford Sleeping Scale in the evening), Sleep quality (Scored by the Groningen Sleep Questionnaire in the morning) and Sleep quantity (Scored in the morning).
