The Best Probiotic to Take After Antibiotics

Finishing a course of antibiotics can leave your gut feeling off—sometimes literally. While antibiotics are essential for fighting bacterial infections, they don’t discriminate: they wipe out harmful bacteria along with the beneficial ones, often disrupting the natural balance of your gut microbiome. This is where probiotics come in, and not just any strain will do.

One of the most researched and effective options is Lactobacillus rhamnosus GG, commonly known as LGG®. Unlike many probiotics that struggle to survive stomach acid and antibiotic exposure, LGG® has been shown in numerous studies to withstand these challenges, making it particularly useful during and after antibiotic treatment. It helps maintain gut integrity, supports immune function, and—importantly—has been proven to reduce the risk of antibiotic-associated diarrhoea, one of the most common side effects.

What sets LGG® apart is its track record. It’s one of the most studied probiotic strains in the world, with decades of clinical research backing its safety and effectiveness, even in children and older adults. Taking it alongside antibiotics (just space them a few hours apart) can help preserve your gut health and speed up recovery.

Of course, not all probiotics are created equal. While many supplements boast high CFU counts or a wide variety of strains, it’s the quality and resilience of the strain that matters most. LGG® stands out not for being flashy, but for being reliable. If you're looking for a straightforward, science-backed way to support your gut after antibiotics, it’s hard to beat a supplement containing Lactobacillus rhamnosus GG.
