Probiotics are the good bacteria that improves digestion and elimination, balances gut flora, and helps stimulate the growth of microorganisms while outnumbering the bad bacteria within the gut. The intestinal system can get weakened by many negative factors that can encourage the growth of bad bacteria. Studies have shown that digestive issues are often caused by the lack of proper balance of gut bacteria. Probiotics are so tiny that billions in a single dose are needed to be effective. But, not all probiotics are created equal, and it that’s where it can be confusing! Their effectiveness can vary depending on the bacterial strains they contain, the way they are made, and quality control in production.
