Probiotics are an ideal health supplement One of the most essential aspects of keeping good health is to have a well functioning digestive system.

Some of the most common ailments that people suffer from is an impaired digestive system, which leads to a host of other related medical ailments. In fact, most chronic ailments that occur in people start in the digestive system. And when the digestive system is impaired and not functioning normally it automatically reduces the levels of friendly bacteria in the body, which leads to weakening of the immune system. That is where probiotics play an important role in building up the presence of friendly bacteria within the body. Probiotics are a live cultured type of friendly bacteria that benefit the digestive system when taken in the right proportion. The human digestive tract actually is home to a wide variety of naturally occurring flora, which includes both good and bad bacteria. There are more than 400 different strains of bacteria that populate the digestive tract. Of these the most commonly found are Bifidobacteria bifidum and L. acidophilus. When there is an overgrowth of harmful bacteria in the gut it leads to an outbreak of Candida, which can effectively be controlled by the use of probiotics. One effective way to treat a Candida infection is to buy Threelac, which is known to inhibit and effectively treat recurring Candida infections in the digestive tract.
