Bacillus subtilis DE-111 is a patented probiotic strain with a tough spore coat. That coat shields it from stomach acid and bile, so it reaches the intestines intact. Unlike fragile probiotic bacteria, this spore form needs no refrigeration and stays stable on the shelf.
People take DE-111 to promote regular digestion and a balanced gut microbiome. It also supports immune function through the gut-immune connection. Some use it to ease occasional digestive discomfort or to help restore gut flora after antibiotics.
Take one capsule or powder serving once daily, with or without food. No refrigeration needed, making it convenient for travel. Most people handle it fine, though some notice mild bloating or gas when starting.
