picto-jaime A proven effectiveness

Lactium® is the ideal companion to help you gently manage your emotional state. Clinically proven to be effective in numerous studies, its dosage can be tailored to your specific needs.

LACTIUM® and anxiety

Do you occasionally, or even regularly, feel tense ? Have you already experienced symptoms such as snacking, stomachaches or headaches, fatigue, difficulty sleeping, loss of libido, anxiety before boarding a plane, etc.?  Taking Lactium® as a preventive measure can give you more control over your emotions.
Lactium® acts effectively and naturally on the central nervous system.

It has no side-effects, and is not addictive. Lactium® is a hydrolyzed milk protein and is hypoallergenic. Unlike benzodiazepines, which belong to the anxiolytics family, Lactium® does not have any toxic effect on the body, even at high doses. It is completely natural, and therefore totally harmless.


The effectiveness of Lactium® has been the subject of 9 rigorous clinical studies, conducted between 1999 and 2018 on more than 500 adult volunteers, all supervised by healthcare professionals. These studies were carried out according to the Clinical Best Practice Directive and under the supervision of official ethics committees(1), and used biological means to confirm the positive impact of Lactium® on the body (blood pressure and heart rate). Many people around the world now use Lactium® every day, including Patricia, a 38-year-old working woman: “I sleep longer and better. Everyday problems are now less important to me.”

The results of two studies by CRSSA and BIOFORTIS, conducted in 2001 and 2011 respectively, demonstrated the clinical efficacy of Lactium®. The studies induced stress on the volunteers using the Stroop test, a psychological stress resistance test. This is a widely used technique, provoking mental conflict between the meaning of words (blue, green, yellow or red) and the color in which these words are actually written (Stroop, 1935). Two groups were created for each of these studies:

  • a “Placebo” group which was administered a placebo in the same quantities and at the same frequencies,
  • a “Lactium®” group, to which the researchers gave a dose of Lactium® at a pre-determined frequency.

The CRSSA study was conducted over 30 days with the recommended dose of 150 mg/day of Lactium® on 52 volunteers in perfect health (25 men and 27 women aged 18 to 40, selected at random). The results following the Stroop test showed a reduction in blood pressure for the group which used Lactium®, the physiological response to stress being an increase in blood pressure.

In 2011, the BIOFORTIS study went on to measure – under the same study conditions using the Stroop test – the difference in heart rate between the relaxation period (after stress) and the rest situation (prior to inducement of the stress). A better heart rate recovery was observed when taking Lactium® at 300mg/day for 15 days in 107 volunteers.
