Probiotics are live bacteria and yeasts that are beneficial for health. They are often referred to as 'good', 'helpful' or 'healthy' bacteria.
An imbalance of the natural bacteria or yeasts within our body has been associated with a range of conditions including constipation, diarrhea, weight gain, skin rashes, yeast infections, and a suppressed immune system.
Probiotics may be taken orally in an attempt to restore any imbalance in the normal intestinal or urogenital flora. Probiotics are available as dietary supplements or contained naturally or added to foods such as yogurt, sauerkraut, or kefir.
