HealthAid UltraProbio Formula is a probiotic supplement to support, strengthen and maintain your body's natural digestive and immune system. Probiotics work to keep a healthy balance of intestinal flora. Our digestive system is colonised by billions of bacteria, some of which are known as friendly. Friendly because they work in many useful ways, they can reduce the build-up of wind, boost the immune system, prevent harmful bacteria from taking hold (helping to prevent infections) and help us to absorb nutrients from our diet. Factors such as poor diet, antibiotics, stressful lifestyle, food poisoning, alcohol can destroy good bacteria allowing undesirable bacteria to multiply. A decrease in beneficial bacteria may lead to digestive problems. HealthAid Ultra Probio reduces the amount of harmful bacteria by replenishing and maintaining the friendly bacteria. HealthAid UltraProbio is a unique formulation containing a superior blend of 100 billion live cultures, using 14 different acid and bile resistant strains to ensure that the bacteria are not destroyed by the stomach juices before they reach the intestines. HealthAid Ultra Probio is also fortified with a prebiotic (FOS), to help stimulate the proliferation and survival of 'friendly' bacteria". Restoring a healthy bacterial balance in the gut can help to calm digestive complaints such as bloating, flatulence, diarrhoea and constipation, boost the immune system and aid the absorption of nutrients from the diet.
