This consumer study has been performed in three countries: France (n = 122), USA (n = 111) and China (n = 105) with subjects suffering of moderate stress and sleep disorders. Lactium® 300 mg has been taken for 1 month, before bedtime. Satisfaction survey and three validated questionnaires were used to evaluate the impact of Lactium® on stress and sleep disorders: PSS-10 to assess stress levels, Spiegel questionnaire to estimate the quantity and quality of sleep, and the PSQI to evaluate sleep habits.

Lactium® significantly improves stress and sleep in France (73% and 69% of improvement, respectively), China (75% and 76%) and USA (85% and 86%). These results of perceived effectiveness have been confirmed by the results of the scientific validated questionnaires (PSS-10, PSQI and Spiegel questionnaire) showing a significant reduction in stress and sleep disorders.
