Nutritionist recommends two probiotic strains to ease stress and improve sleep

Emma Derbyshire, a public health nutritionist and adviser to PrecisionBiotics, points out that up to 40% of Britons regularly experience digestive problems, while less than half recognize the gut’s role in immunity. Citing research on the gut-lung axis, she notes that a balanced microbiome trains immune cells and protects the gut lining. Derbyshire recommends looking for probiotic strains 35624 and 1714, which studies link to reduced gas, abdominal pain, lower cortisol and better sleep, and are included in PrecisionBiotics’ Alflorex® Dual Action Daily Gut and Brain Health Supplement. She adds that limiting ultra-processed foods, managing stress, securing 7-9 hours of sleep and staying physically active further support gut and overall health during the cold season.
