Some yogurts don’t contain live microorganisms or they contain insufficient amounts of them. Check if the label states the strain or strains contained in the yogurt and the number of live cells guaranteed until the best-before date: the product portion recommended for daily consumption must contain at least 109 live cells for at least one of the strains present.8 Most yogurt brands do not contain probiotic strains such as Sustenium’s LGG and B. lactic L H019. Furthermore, each sachet of Sustenium probiotics contains negligible level of calories.
