What is the recommended dosage for Lactobacillus acidophilus?

General: 1-10 billion CFU/day; Ibs Support: 10 billion CFU/day for 4-8 weeks; Lactose Support: 1-2 billion CFU with dairy consumption

What are the side effects of Lactobacillus acidophilus?

Potential side effects include: Mild gas and bloating during initial use, Occasional loose stools, Rare allergic reactions in dairy-sensitive individuals (dairy-cultured strains), Very rare: bacteremia in immunocompromised individuals.

What is Lactobacillus acidophilus and how does it work for gut health?

Lactobacillus acidophilus is one of the most well-known probiotic species, naturally residing in the human intestinal tract and vaginal microbiome. It produces lactic acid and hydrogen peroxide, creating an inhospitable environment for harmful bacteria. Research suggests it may help improve lactose digestion, support immune function, and help maintain a balanced gut microbiome.

What is the recommended dosage of Lactobacillus acidophilus?

Clinical studies have used dosages ranging from 1 billion to 10 billion CFU per day. The strain L. acidophilus NCFM is among the most studied, typically at 1-10 billion CFU daily. It is often combined with other probiotic strains for synergistic effects. Refrigerated products generally maintain higher viability than shelf-stable versions.

Are there side effects or interactions with Lactobacillus acidophilus?

L. acidophilus is generally well-tolerated and has a long history of safe use in both supplements and fermented foods. Mild bloating or gas may occur initially. Individuals taking antibiotics should space their probiotic dose at least 2 hours apart, as antibiotics may kill the probiotic bacteria. Immunocompromised individuals should consult their healthcare provider.

About

Lactobacillus acidophilus is one of the most widely recognized probiotic species, found naturally in the human gastrointestinal tract and fermented foods. It supports digestive health by producing lactic acid that lowers intestinal pH, which may help inhibit pathogen adhesion and support mucosal barrier integrity through enhanced mucin production. Research suggests it may be particularly supportive for lactose digestion and overall bowel regularity.

How It Works

Produces lactic acid lowering intestinal pH to inhibit pathogen growth; inhibits pathogen adhesion to intestinal epithelium via competitive exclusion; enhances mucosal barrier integrity through mucin production stimulation; produces bacteriocins (acidocin, lactacin) with antimicrobial activity.
