OrthoBiotic Powder is a blend of 7 "friendly" gut bacteria that is perfect for children or for those who do not want to swallow pills. The use of these friendly bacteria has been shown to impart numerous benefits for not only digestion, but also immune function. Anyone who is taking or has taken antiobiotics should consider the use of this supplement. If you have problems with yeast this product is a must since it also contains Saccharomyces boulardii (which kills Candida).
