Yes, it is absolutely fine, and advisable to take a friendly bacteria supplement whilst on antibiotics. When prescribed antibiotics, many individuals now choose to supplement their natural bacteria with a live cultures supplement. However, it’s best to select strains that have been extensively researched alongside this type of medication.
It’s important to choose friendly bacteria strains that have been trialled alongside antibiotics and shown to reach the gut alive. Strains in For Those On Antibiotics have been shown to do so in numerous clinical trials, even when taken at the exact same time as antibiotic medication1. The strains in this supplement have been trialled at various life stages including in children2,3 and can be taken during long or short courses of antibiotics.
Like most of our range, we recommend that For Those On Antibiotics, should be taken at breakfast time. It’s fine to take this supplement with breakfast and alongside your antibiotics at the same time. If you take your antibiotics at a different time of day, then still take For Those On Antibiotics with breakfast. If you choose to take a different live cultures supplement, then note that it may be necessary to leave a two-hour gap from your medication dose. Ideally however, it’s best to take strains such as Lactobacillus acidophilus/helveticus Rosell-52, Lactobacillus rhamnosus Rosell-11 and Bifidobacterium lactis Lafti B94 which can be taken at the same time as your medicine.
When the correct strains are taken, friendly bacteria can support you whilst on the antibiotic medication4. It’s best to start taking For Those On Antibiotics right away at the start of your course but don’t worry if you miss a day or so at the beginning, just continue until the pack is complete. Many people like to continue taking live cultures once they have finished their course of medication, to maintain their support of the gut microbiome.

Following the taxonomic updates advised by a global team of scientists and published in April 2020, a reclassification has been proposed for the L. rhamnosus species. The L. rhamnosus strain in For Those On Antibiotics may therefore now also be known as Lacticaseibacillus rhamnosus Rosell-11.
