Gut healthy

“There is an emerging body of evidence that gut microbiome affects cognition, behaviour and brain health,” says Dr Levitin, and while it’s early days, we do know that the brain chemical serotonin “is an important regulator of mood, memory, and anxiety.” Nearly all of the serotonin that ends up in the brain is manufactured in the gut so a healthy gut is important, but we don’t yet know how to measure the quality of our gut microbiome or how to fix it. Most probiotics don’t survive the acidic journey through the gut, so look for one with evidence such as Symprove, and source probiotics in food such as yoghurt, kefir, and anything fermented such as sauerkraut or pickles.
