Lactobacillus acidophilus Bacteria in Review

In recent years, lactobacillus acidophilus bacteria has gained recognition as a beneficial probiotic, offering support for digestive health, immune system function, and more. Below, we're going to explore lactobacillus acidophilus bacteria, the benefits it can bring to your health, and how you can increase its presence in your gut.

What is Lactobacillus acidophilus?

Definition and Characteristics

Lactobacillus acidophilus is a Gram-positive, rod-shaped facultative anaerobe bacterium that belongs to the Lactobacillus genus and can thrive in both the presence and absence of oxygen. Lactobacillus acidophilus is one of the most commonly used probiotic strains as it plays a crucial role in maintaining gut and vaginal health. L. acidophilus is capable of fermenting carbohydrates, primarily lactose, to produce lactic acid as a byproduct. The production of lactic acid contributes to the acidic environment in the gut and vagina, inhibiting the growth of harmful bacteria and yeast.

History and Discovery

Lactobacillus acidophilus was first isolated and identified by the American bacteriologist Ernest Hitchens in 1900. In the early 20th century, it was discovered that certain strains of lactobacilli, including L. acidophilus, could help treat digestive disorders and improve gut health. In the 1920s and 1930s, Nobel laureate Élie Metchnikoff's research on the gut microbiota brought attention to the health benefits of lactic acid bacteria. Metchnikoff suggested that consuming fermented milk products containing lactobacilli could promote healthy aging and longevity. This laid the foundation for the development of modern probiotic products containing L. acidophilus and other beneficial bacteria.

Occurrence and Habitat

Lactobacillus acidophilus naturally occurs in various habitats, including the human gastrointestinal tract, the oral cavity, and the vaginal environment. It is also found in the gut microbiota of certain animals like cows, pigs, and chickens. In addition to its natural presence in the human body, L. acidophilus can be found in fermented foods such as yogurt, kefir, sauerkraut, kimchi, and some types of cheese. These fermented foods can be a rich source of live lactobacillus acidophilus and can contribute to a healthy gut microbiota when consumed as part of a balanced diet.

Benefits of Lactobacillus acidophilus

Digestive health from Lactobacillus acidophilus bacteria

One of the primary benefits of lactobacillus acidophilus is its ability to support digestive health. By helping to break down lactose, this probiotic can aid in the prevention of lactose intolerance symptoms. Moreover, it can help alleviate symptoms of irritable bowel syndrome (IBS), as demonstrated by the LAPIBSS clinical trial.

Immune system support

Lactobacillus acidophilus bacteria can also support immune function by inhibiting the growth of harmful bacteria in the gut. In addition, the probiotic can modulate the immune response, helping to protect against allergies and inflammation, as seen in this clinical trial on atopic dermatitis.

Vaginal Health and Lactobacillus Acidophilus for BV

A healthy vaginal environment is maintained by a delicate balance of various microorganisms, predominantly lactobacillus bacteria. Lactobacillus acidophilus is one of the essential species that helps to keep the vaginal ecosystem in harmony. It does so by producing lactic acid and hydrogen peroxide, which in turn create an acidic environment that inhibits the growth of harmful bacteria and yeast.

Bacterial Vaginosis (BV)

Bacterial vaginosis (BV) is a common vaginal infection caused by an imbalance of bacteria in the vagina, and when the levels of lactobacillus bacteria, particularly lactobacillus acidophilus, decrease, it allows the growth of harmful bacteria such as Gardnerella vaginalis. This imbalance can lead to BV, characterized by symptoms like itching, burning, and a fishy-smelling discharge.

Using Lactobacillus Acidophilus for BV

Lactobacillus acidophilus can be an effective treatment for BV by restoring the balance of bacteria in the vagina. There are several ways to increase lactobacillus acidophilus levels in the vaginal area:

1. Oral Probiotics: Consuming oral probiotics containing lactobacillus acidophilus, such as MicroBiome Restore, can help to repopulate the vaginal environment with beneficial bacteria.
2. Vaginal Probiotic Suppositories: Probiotic suppositories containing lactobacillus acidophilus can be inserted directly into the vagina to help restore the balance of bacteria. These suppositories are usually available over-the-counter and can be used as directed by a healthcare provider.
3. Probiotic-rich Foods: Consuming fermented foods, such as yogurt and kefir, which contain lactobacillus acidophilus, can also help to support a healthy vaginal environment. Choose unsweetened, natural yogurt with live and active cultures to ensure you are getting the probiotic benefits.
4. Maintaining Vaginal Hygiene: Practicing good vaginal hygiene can help to support a healthy balance of bacteria. This includes wearing breathable, cotton underwear, avoiding harsh soaps and douches, and wiping front-to-back after using the restroom.

While using lactobacillus acidophilus for BV can be an effective approach, it is essential to consult with a healthcare provider for proper diagnosis and treatment, as other infections can cause similar symptoms. In some cases, a healthcare provider may recommend antibiotics in conjunction with probiotics to treat BV effectively.

Other potential benefits

There are numerous other potential benefits of lactobacillus acidophilus bacteria, including its role in improving menopausal symptoms such as hot flashes, paresthesia, nervousness, melancholia, fatigue, arthralgia, headache, heart palpitation, formication, and vaginal dryness, as shown in a study published in the Journal of Clinical Medicine. Lactobacillus acidophilus can improve menopausal symptoms

Sources of Lactobacillus acidophilus

Food sources

Lactobacillus acidophilus bacteria can be found in a variety of fermented foods, such as yogurt, kefir, sauerkraut, and tempeh. Consuming these foods can help increase the levels of this probiotic in your gut. Lactobacillus acidophilus can be found in many fermented foods including kimchi

Dietary supplements

Lactobacillus acidophilus probiotic supplements are another option for increasing your intake of this beneficial bacteria. One such supplement is MicroBiome Restore, which contains lactobacillus acidophilus in its formulation.

How to increase Lactobacillus acidophilus bacteria in the gut

Prebiotics and probiotics

To support the growth of lactobacillus acidophilus bacteria in the gut, it is essential to consume both prebiotics and probiotics. Prebiotics are dietary fibers that feed the beneficial bacteria in the gut, while probiotics are live bacteria that can improve gut health. You can find a list of natural prebiotic foods in this top 7 dietary prebiotics article.

Lifestyle changes

Making certain lifestyle changes can also help increase lactobacillus acidophilus bacteria in your gut. These changes may include reducing stress, getting adequate sleep, and exercising regularly. For more tips on how to boost gut bacteria diversity, check out this informative article.

Other strategies

To further support lactobacillus acidophilus growth in your gut, consider incorporating fermented foods into your diet and taking a high-quality probiotic supplement, like MicroBiome Restore. Additionally, learn the best time to take prebiotics to maximize their benefits. MicroBiome Restore contains Lactobacillus acidophilus bacteria in its formulation

Risks and precautions

Possible side effects

While lactobacillus acidophilus is generally considered safe, some people may experience side effects such as gas, bloating, or diarrhea when first taking a probiotic. These side effects are usually mild and subside within a few days.

Safety concerns & precautions

Before starting any new supplement, it is essential to consult with your healthcare provider, especially if you are pregnant, nursing, or have a compromised immune system. Additionally, make sure to choose a reputable supplement brand and follow the recommended dosage instructions.
