Probiotics have been shown to be very effective in improving overall health.Since the days when acidophilus first entered the vocabulary there has been a quest for the "perfect" probiotics. The word "probiotic" means "for life," as opposed to "antibiotic," which means "against life." It has been recognized for centuries that cultures added to such foods as milk, producing yogurt and cheese, are beneficial to human health: Hence, they are probiotics. These probiotics are composed of many different strains of bacteria that thrive in the intestine and could thus be called "intestinal flora." Included within this category of bacteria are not only acidophilus but many other strains - more than 400 different species - including bifidus, bactilis subtilis and various substrains, as well as soil-based organisms, which under normal circumstances release "beneficial enzyme, hormone and nutrient by-products" into the soil. Numerous scientific studies have been conducted using a large variety of probiotics or intestinal bacterial flora, with a wide spectrum of results and probiotics therapy being recommended by scientists and doctors in many parts of the world.
