Night Protein is a category of supplements that generally encompasses slowly absorbing protein products. Typically, these are based on micellar casein, but in a few cases, the ingredients also contain admixtures of other protein types, such as whey concentrate or milk protein, which produces a blend of both fast and slow absorbing protein types.
Micellar casein is produced via a process of microfiltration from fresh or skimmed cow's milk and typically contains about 70 to 80 % of protein. This type of protein has a slower and steadier absorption rate, which sits at about 6 g/h, compared to whey protein’s 10 g/h. For this reason, it is commonly used at nighttime, often substituting cottage cheese or curd. This slow absorption rate is caused by the colloidal protein particles, known as micelles. If you are preparing to fast for an extended period of time and want to make sure that your muscles are well supplied with high quality protein in the meantime, this category of products is ideal for you. Prototypical products in this category include micellar casein or FueNight.
