A healthy digestive system contains a healthy balance of ‘friendly’ and ‘unfriendly’ bacteria. They are constantly in competition. Certain factors such as poor diet, stress, ageing and antibiotics can increase ‘unfriendly’ bacteria or decrease the concentration of both ‘friendly’ and ‘unfriendly’ bacteria, resulting in digestive tract problems and compromised immunity. Restoring a healthy bacterial balance in the gut is important to calm digestive complaints such as bloating, flatulence, diarrhoea and constipation
