Our Original Purition is made with some whey protein isolate, which is exceptionally low in lactose. To put everything in context, the average cup of tea with a light splash of milk will contain roughly 160mg of lactose. In stark contrast, there is less than 4mg of lactose in a serving of Original Purition, which is around 4,000 parts per million lactose and as such shouldn’t trigger or aggravate IBS or prompt bloating. Trying a few individual sachets (via our Discovery Boxes) might be a sensible 1st step!
