Protects the liver from effects of alcohol

How does alcohol damage the liver?

Alcohol damages the intestinal barrier.

It disrupts the normal balance of intestinal good germs, resulting in the generation of toxins by harmful gut bacteria. Absorption of these toxins through the damaged intestinal surface into the blood stream and liver results in inflammation of the liver, eventually destroying the liver.

A diagrammatic representation of the events which lead to alcoholic liver damage is shown here:

GG probiotic protects the stomach, intestines and liver from the damaging effects of alcohol.

GG probiotic has the capability of breaking down alcohol to acetate, a harmless breakdown product. This capability has the potential of reducing the immediate damaging effect of alcohol.

Since LACTOGG®’s probiotic strain can breakdown alcohol, it represents another system besides that of the liver, which can detoxify alcohol.

Breakdown of acetate by Lactobacillus GG [Nosovo et al 2000]

In animal studies, Lactobacillus GG conserved the intestinal barrier and maintained intestinal bacterial composition despite the presence of alcohol. Taking this probiotic strain protected the liver from being destroyed by toxins which were produced by the harmful intestinal germs.

Most importantly, it could reverse inflammation in the liver.

GG probiotic’s beneficial effect was noted in both prolonged alcohol consumption and after binge drinking.

How should LACTOGG® be taken?

Supplement amount:

At least 1 sachet or 1 capsule a day.
