Gut health Diarrhea BB-12® LA-5®

4 Min read

Antibiotics are thought to disrupt the balance and diversity of the gut microbiome by eliminating not only the harmful, pathogenic bacteria but also some of the resident beneficial bacteria.^{1, 2} This often results in diarrhea, known as antibiotic-associated diarrhea (AAD). Clinical studies have shown that supplementation with a blend of the Lactobacillus acidophilus, LA-5^® and Bifidobacterium, BB-12^® probiotic strains (hereafter referred to by use of the trademarks LA-5^® and BB-12^®) may be effective at reducing the duration and severity of AAD.^{3, 4}

Antibiotics frequently affect the digestive system

Many different types of bacteria live in our gut and usually coexist harmoniously due to the many bacteria being optimally balanced. When in balance, the bacteria support our health. Antibiotics often disrupt this balance, which can potentially enable harmful bacteria to multiply beyond their normal numbers,⁷ altering how the digestive system functions. This is why treatment with antibiotics often causes mild and temporary diarrhea known as antibiotic-associated diarrhea.^{6, 8}
AAD can occur not only while taking a course of antibiotics but also for up to eight weeks after the course of antibiotics has finished. Symptoms of AAD typically include frequent episodes of loose and watery bowel movements, and crampy abdominal pain.^{9, 10}

Fact

AAD is a benign and self-limiting diarrhea that may occur with the use of antibiotics.^{5, 6}

Probiotics may help restore balance to the microbiome, reducing the risk of AAD

The BB-12® and LA-5® probiotic strains have been investigated in clinical studies and have been associated with reducing the duration of AAD.^{3, 4}The two probiotic strains are thought to bring about beneficial effects by producing substances that are toxic for harmful bacteria.^{11, 12, 13} The BB-12® and LA-5® probiotic strains also help improve the immune system by strengthening our immune response,^{14, 15} better enabling the body to combat new viral and bacterial infections.

BB-12^® and LA-5^® probiotic strains may reduce the duration of AAD

A high-quality clinical study investigated the effectiveness of the LA-5^® and BB-12^® probiotic strains at reducing the risk and severity of AAD.³ All participants were given a seven-day course of an oral antibiotic. On the same day that the antibiotics course started, half of the participants were given a placebo and the other half were given a blend of the LA-5^® and BB-12^® probiotic strains. Participants continued with the placebo or probiotic blend for a further seven days after the course of antibiotics was completed.³
Only 10.8% of the probiotic group experienced AAD, compared to 15.6% of the placebo group. Further, the duration of the AAD was significantly shorter in the probiotic group (two days) compared to the group who took a placebo (four days).³
Of those participants who did experience AAD, severe diarrhea occurred in 96% of the placebo group, compared to just 31.6% of the probiotics group.³

Fact

Antibiotics disrupt the balance of bacteria in the gut microbiome, often resulting in AAD.¹

Ask your doctor about probiotics when being treated with antibiotics

Antibiotic treatment disrupts the balance of the gut microbiome and can result in an overgrowth of harmful, pathogenic bacteria. This often results in the development of antibiotic-associated diarrhea. Clinical studies suggest that supplementing with the BB-12^® and LA-5^® probiotic strains may help reduce the duration and severity of AAD.^{3, 4}
