There is an increasing amount of people who are unable to digest certain foods, for example lactose in dairy products. The ability to digest macro nutrients (proteins, fats, carbohydrates) depends on the efficient production of digestive enzymes. For some people production of these enzymes is ineffective and a supplement containing digestive enzymes may be needed. Biocatalysts has a range of enzymes that can be used in digestive aid (or dietary supplement) applications.
