Intoleran Once A Day is a probiotic helping to digest dairy products, useful for lactose intolerance. The capsules contain a combination of 6 specially selected lactic acid ferments and lactase precursors to maintain optimal digestions of lactose and nutrient uptake. Since only one capsule needs to be taken per day, this product is a very convenient solution. It is especially helpful whilst on holiday, but also suitable for daily and long-term use. Due to the fact that the lactase precursors need some time to build up and take effect, the once a day capsules have an optimal effect from between 5 and 14 days after the first use and need to be taken every day. This product is also ideal for children, from the age of 4 years old..
