Lactobacillus Acidophilus Side Effects

Lactobacillus Acidophilus Side Effects

One of Lactobacillus acidophilus’s most common side effects (L. acidophilus) is bloating. While this usually subsides with use, it can be harmful to the dental enamel if acidophilus is directly exposed to the teeth. More serious side effects of L. acidophilus include hives, difficulty breathing, and vomiting. These side effects should be reported to a healthcare provider immediately. Premature infants and children are at higher risk of these adverse reactions.

Weight gain

Some people take Lactobacillus acidophilus supplements for weight loss, but not everyone experiences these side effects. Although these friendly bacteria are generally safe, they can interact with other medications, including those used for gastrointestinal disorders. The good idea is to discuss the supplement’s side effects with your healthcare provider. You may have a more serious condition or be taking medication for another condition. If you have a compromised immune system or have a damaged gut, you should avoid taking acidophilus. Also, people who take antibiotics should avoid taking Lactobacillus, as they can kill acidophilus bacteria.

A study published in the journal Gut and Digestive Diseases suggested that taking Lactobacillus for a month could help reduce the risk of ulcers in people with H. pylori. While Lactobacillus is not a cure for H. pylori, it can help treat various conditions ranging from irritable bowel syndrome to constipation. It can also be used to prevent necrotizing enterocolitis in premature infants.

Another study showed that taking Lactobacillus for two months prevented a significant increase in total body fat mass. However, the results of this study were not conclusive. This was not due to a weight reduction but rather to increased energy. In the same study, women who ate Lactobacillus for four months experienced decreased overall body fat mass.


People with low immune systems and weakened guts should avoid taking acidophilus. These bacteria can cause serious complications. These bacteria have also been implicated in serious diseases, such as abscesses and meningitis. This is why it is important to learn about potential acidophilus side effects. Below are some of these side effects and what you can do to minimize them.

Although it may not be a cure for diarrhea, it can help prevent the illness. It is also beneficial for people with digestive issues, and it has been used for years to fight antibiotic-associated diarrhea and indigestion. However, studies have not shown that it is effective for these conditions. If you are taking antibiotics and have diarrhea, consult your doctor to learn whether lactobacillus acidophilus is right.

Some studies have shown that Lactobacillus acidophilus may have diarrhea-causing side effects. However, other studies are needed to assess the risks associated with this health supplement. A few studies have been published to date. One study was published in N Engl J Med in 1978, including 50 American tourists who traveled to Mexico. Twenty-six of them received Lactobacillus, while 24 were given placebo preparations. The incidence of diarrhea was recorded over four weeks. Interestingly, the two groups had similar incidences of diarrhea during the active treatment period. Unfortunately, the researchers did not specify the strain used or how the preparation was freeze-dried.


Although most people experience no side effects from lactobacillus acidophilus, some people may have various gastrointestinal issues, including diarrhea, bloating, and abdominal pain. Although acidophilus is generally safe, it may cause problems if your immune system is compromised. In addition, acidophilus can weaken the tooth enamel when exposed to the saliva. For this reason, it is important to speak with a healthcare provider before starting this probiotic supplement.

Some of these symptoms may be related to the lactose in the product. The resulting bloating, gas, and pain can be uncomfortable but are usually mild. Symptoms of an allergic reaction to acidophilus include rash, itching, swelling, and difficulty breathing. People with a compromised immune system should avoid taking acidophilus, as it may cause serious side effects.

Some other side effects of lactobacillus acidophilus are related to the bacterial strains used in the preparation. In the food industry, the Lactobacillus acidophilus strain is used to treat several conditions. It is effective in treating conditions such as diarrhea and irritable bowel syndrome. However, some people report experiencing bloating as a result of the supplement.

Children with diarrhea may benefit from this supplement. Its use reduces the severity of diarrhea caused by the rotavirus. One study found that children treated with Lactobacillus could recover a full day faster than children with diarrhea who did not take it. It is important to note that smaller doses of Lactobacillus are not as effective as larger ones. For best results, use 10 billion colony forming units (CFU) over 48 hours.


Although Lactobacillus acidophilus (L. acidophilus) is a beneficial microorganism, some people find it a side effect. Some believe that this bacteria can help promote good health, prevent infections, and balance the flora in the vagina and intestines. It is most commonly found in yogurt and belongs to the Lactobacillus family of bacteria. These bacteria convert sugars into hydrogen peroxide and lactic acid. They also inhibit the growth of undesirable bacteria in the intestines. Furthermore, some proponents claim that acidophilus may help weight loss and strengthen the immune system.

Other side effects of Lactobacillus acidophilus treatment include constipation. This condition is caused by a slowed stool transit through the large intestine. As a result, the stool loses its moisture and becomes hard and difficult to pass. In some patients, the condition may also cause diarrhea or a combination of diarrhea and constipation. The patient may also experience extreme bowel movements within the same bowel movement.

Researchers will examine the efficacy and safety of probiotic treatment for constipation in clinical trials. The trial results will be published in specialized journals and communicated to participants via text message. This study will help determine whether a combination of Lactobacillus acidophilus and Bifidobacterium sp. strains can improve the frequency and quality of bowel movements. Different strains may have different effects and safety profiles.

Allergic reactions

Some research suggests that Lactobacillus may reduce the risk of allergic reactions, especially in children. A study conducted by Folster-Holst et al. in 2009 showed that the probiotic E. coli reduced the risk of serum-specific IgE allergies in children. However, in children with asthma, L. acidophilus did not reduce the risk of allergy in children.

Prophylactic treatment with Lactobacillus acidophilus is a viable natural alternative to antibiotics and other medications. Several studies in humans and animals have shown that the L-92 strain of Lactobacillus acidophilus has strong antiallergic effects. It is also used in cultured milk, yogurt, and dietary supplements in Japan. Allergic reactions to lactobacillus acidophilus are rare, but they can occur in some individuals.

Intestinal flora is believed to play a role in inflammatory diseases and mucosal immunity. Allergic responses are thought to develop when the immune system has not been exposed to many microbial organisms. Exposure to microbial flora changes the Th1/Th2 balance early in life, favoring the Th1 response. The microflora of people with allergic diseases differs from those in industrialized countries.

People with weakened immune systems or intestinal damage should avoid taking acidophilus. While most of these side effects subside with time, it is good to talk with your healthcare provider before taking acidophilus. It is also important to note that excessive acidophilus consumption may cause serious infections. For example, acidophilus has been linked to blood infections in patients with central lines (long, thin, flexible tubes placed in a large vein in the body). People with gastrointestinal disease or cirrhosis may also have a higher risk of suffering from acidophilus-induced blood infections.

Lactobacillus Acidophilus Side Effects

Irritable bowel syndrome

Several studies have reported positive effects of Lactobacillus acidophilus on symptoms of irritable bowel syndrome. Several food-associated Lactobacillus species have GRAS status. These studies evaluated the efficacy of a two-strain mixture of L. acidophilus for irritable bowel syndrome. The most recent report found that L. acidophilus treatment significantly reduced abdominal pain compared to placebo after four weeks.

However, research on the safety of Lactobacillus acidophilus has not been conclusive. Many people with IBS report experiencing alternating symptoms. This is why a high-quality daily probiotic is a must. Moreover, many experts believe that imbalanced gut flora contributes to IBS. Two strains of Probiotics have been studied in patients with IBS: Lactobacillus acidophilus NCFM and Bifidobacterium lactis Bi-07. Both strains are effective in relieving abdominal distension, bloating, and cramps.

In addition, studies on IBS-C have shown that altering the intestinal microflora improved the symptoms of constipation and abdominal pain. According to studies by Bonaz L, Nimri N, Ghanem L, and O’Morain CA, changes in the microflora in the intestinal tract may help alleviate IBS-C symptoms.
