Overview
Genus of lactic acid bacteria found in fermented foods such as yogurt and sauerkraut.
Interactions
Lactobacillus strains produce short-chain fatty acids (SCFAs) that lower colonic pH, increasing the solubility and passive absorption of calcium in the large intestine.
Certain Lactobacillus strains (L. plantarum 299v) increase iron absorption by producing lactic acid that solubilizes non-heme iron and reduces Fe³⁺ to absorbable Fe²⁺.
Lactobacillus strains produce short-chain fatty acids that lower intestinal pH, increasing magnesium solubility and enhancing its passive paracellular absorption in the colon.
Research status
Gut microbiome diversity declines with age.
