The short answer to your question is that the ratio is about 1:10, which means if expressed in LU, the formula on the website would read Lipase 14,000 LU. The long answer is that FIP and LU are both attempts to accurately assay enzyme activity. Assay accuracy and reproducibility are the most stringent requirements for the determination of enzyme potencies in nutraceutical formulations. Weight measures such as mgs tell you nothing about enzyme activity. You could have 5,000 mg of an enzyme that had been cooked at high temperature and have 0 activity left. FIP (an acronym for Fédération Internationale Pharmaceutique/International Pharmaceutical Federation) is a more accurate standard than LU (an acronym for Lipase Units). Over the last 20 years, FIP has emerged as the overwhelming choice over LU for measuring enzyme activity in fats because it produces more accurate and consistent results. Enzyme activity is determined by the quantity of substrate (fats, proteins, carbohydrates — whatev
