Overview of Lactobacillus Acidophilus

June 2, 2023

Overview of Lactobacillus acidophilus.

Lactobacillus acidophilus, a bacterium first discovered in 1900 from the feces of infants, has undergone significant transformations in our understanding of its metabolic and functional characteristics. It is primarily found in the intestinal tracts of both humans and animals, and is particularly abundant in milk-fed infants and individuals consuming high amounts of milk and lactose.

Is lactobacillus acidophilus fungus or bacteria?

Lactobacillus is a genus of lactic acid bacteria known for its nonspore-forming, rod-shaped, Gram-positive characteristics. It displays a wide distribution across different habitats, including plants, dairy products, and the gastrointestinal tract of various organisms.

What does lactobacillus acidophilus come from?

The acidophilus bacterium, named for its affinity for acidic environments, is typically obtained from the intestinal tracts of humans and animals. It is commonly found in the feces of infants who are fed with milk, as well as in older individuals who consume diets high in milk, lactose, or dextrin.

What are probiotics?

Probiotics refer to living microorganisms, including bacteria, that have a beneficial impact on human health. The World Health Organization provides a definition for probiotics as “live microorganisms that, when administered in appropriate amounts, confer a health benefit on the host.” These microorganisms are naturally present in the human body, primarily in the gastrointestinal tract, where they form unique populations. The types, quantities, and specific locations of probiotics can vary within the body. Probiotic bacteria exert their positive effects on health through various means, including influencing food absorption, enhancing immunity, and modulating inflammation levels. Probiotics can be obtained from certain foods like yogurt, and they are also available as concentrated formulations in the form of dietary supplements, which can be ingested orally or applied topically to the skin or mucosal surfaces of the body.


Uses of lactobacillus acidophilus.

  • Bacterial vaginosis. The utilization of acidophilus through oral consumption or the application of acidophilus suppositories or yogurt containing acidophilus to the vaginal area has been proven to be effective in the treatment of this specific type of vaginal inflammation.
  • Lung infections. There is a possibility that acidophilus could play a role in diminishing both the quantity and intensity of respiratory infections in children.
  • Certain types of diarrhea. The simultaneous use of antibiotics and a specific combination of acidophilus and other lactobacillus strains has the potential to alleviate symptoms like diarrhea, bloating, and cramps that arise from an infection caused by a bacterium associated with conditions ranging from diarrhea to severe inflammation of the colon (C. difficile infection). Moreover, this particular probiotic formulation may also help reduce the occurrence of antibiotic-associated diarrhea and C. difficile infection in hospitalized individuals.
  • Eczema. The consumption of acidophilus through oral means during pregnancy, by breastfeeding mothers, and in infants appears to be linked to a reduction in the occurrence of eczema (atopic dermatitis) among infants and young children.

What is lactobacillus acidophilus supplements used to treat ?

Acidophilus has been recognized as a potential option for relieving symptoms related to diverse health conditions. It may offer assistance in the management of:

  • Diarrhea: Acidophilus supplementation may be beneficial in reducing the likelihood of developing diarrhea as a side effect of taking antibiotics. Moreover, it might provide relief for diarrhea caused by an infection.
  • Vaginal inflammation: Acidophilus supplementation may be a viable option for managing the symptoms of bacterial vaginosis, a type of vaginal inflammation.
  • Yeast infections: Acidophilus supplementation may offer potential benefits in treating and preventing vaginal yeast infections. Additionally, it can be utilized as a treatment for yeast infections in the mouth (oral yeast infections).
  • Acidophilus has been explored for its potential in providing relief from symptoms associated with a range of conditions, including:
  • Inflammatory bowel disease (IBD). 
  • Gum disease.
  • Urinary tract infections.

They can provide you with essential information regarding the potential benefits and possible side effects. If you decide to take acidophilus, it is important to follow the recommended dosage and use it according to the instructions given by your healthcare provider or pharmacist.
Several food and beverage products are known to contain acidophilus probiotics. Look for labels on specific items that indicate the presence of “live active cultures.” Some labels may even specify the complete name of the bacteria. Examples of food and drink options that may include acidophilus are:

  • Yogurt.
  • Kefir (fermented milk drink).
  • Kimchi.
