Lactobacillus acidophilus

Lactobacillus acidophilus

What is Lactobacillus acidophilus?

Lactobacillus acidophilus, also often referred to as L. acidophilus, is a highly beneficial bacterium naturally found in the human gastrointestinal tract, mouth, and vaginal microbiota. It is classified as a probiotic, meaning it is a live microorganism that can contribute to the maintenance of normal gut flora, and support overall digestive health. Alongside its ability to provide digestive support, L. acidophilus has been linked to various other impressive benefits that make it valuable for maintaining good health.

Health Benefits:

Supports Digestive Health

Evidence indicates that L. acidophilus can support the maintenance of balanced and healthy gut flora. This modulation of the gut microbiota is in part achieved through L. acidophilus's ability to colonize the intestinal mucosa and form a protective biofilm, helping to prevent the adhesion of pathogenic bacteria and hindering its overgrowth. L acidophilus can also lower the pH level of the gut through the production of lactic acid and acetic acid, further creating an unsuitable environment for many harmful microorganisms.

Boosts the Immune System

L. acidophilus may also help to boost the immune system, helping to fight infections and maintain good health. One study found that the administration of L. acidophilus La-14 could increase the immune response as shown through increased levels of lymphocyte cells and showed anti-inflammatory activity. L. acidophilus can also support immunity through its powerful ability to help prevent the colonization of harmful pathogens, protecting the body from infections.

Supports Female Intimate Health

Lactobacilli microorganisms are naturally found in the healthy human vagina and help to prevent the growth of harmful bacteria and yeast, as well as supporting a healthy vaginal pH level. Research has repeatedly linked reduced levels of lactobacilli to the occurrence of various vaginal infections, highlighting the key role of lactobacilli in female intimate health. 

History:

L. acidophilus has a long history of use through the consumption of fermented foods such as yoghurt, kefir, miso, sauerkraut and kimchi. However, the use of L. acidophilus became much more common in the early 20th century following its discovery in the human intestine. This powerful bacterium quickly became popular for its various health benefits, and ability to both survive stomach acid and effectively adhere to the intestinal lining.

Typical Use:

Typically L. acidophilus is used in the form of capsule or powder form supplements ,and is frequently combined with prebiotics or complementary probiotic strains to provide more comprehensive microbiome support.
