Lactic acid bacteria and vitamin D3 for the immune system Lactobacilli and bifidobacteria are among the most common bacteria found in the human gut. The development of a childs gut flora can be supported by using a lactic acid bacteria supplement containing various strains of beneficial lactobacilli and bifidobacteria. A childs gut flora is particularly vulnerable to antibiotics in the early years. Even short-term use of these medications can destroy beneficial bacteria and thus alter the composition of the gut flora for months. Lacto Seven Kids can be used daily, especially during antibiotic treatment. The lactic acid bacteria in Lacto Seven Kids are coated with a protective layer (Bio-Support™ technology). This ensures that the bacteria reach the gut alive.
