Protesan R contains FK-23 (heat-treated lactic acid bacteria) plus both indigestible dextrin (dietary fiber) and oligosaccharides. Compared to Protesan S (oligosaccharides only), it is a balanced formulation with enhanced auxiliary ingredients supporting the intestinal environment.

Among the Protesan series lineup (B: 300 billion → R: 1 trillion → S: 4 trillion → S3: 12 trillion), Protesan R is a central product praised for its cost performance and ease of use, allowing the daily recommended amount to be taken with 1 to 2 packets.
Unlike Protesan S, it also contains indigestible dextrin (dietary fiber) to support the intestinal environment, making it a more balanced raw material design. Fragrance-free, sweetener-free, allergen-free formulation suitable for a wide range of people from infants to the elderly.

Nichinichi Pharmaceutical's lactic acid bacteria supplements use three types of lactic acid bacteria materials processed differently. All are made from the same bacterium "Enterococcus faecalis," but their properties and names differ depending on the depth of processing.
A material where Enterococcus faecalis is heat sterilized and concentrated. The bacterial body remains intact and is absorbed from the Peyer's patches in the small intestine. Used in the Protesan series (B, R, S, S3). Holds six patents.
A material where FK-23 is further enzyme treated to dissolve the bacterial cell wall and extract internal components (nucleic acids, vitamins, minerals, etc.). Used in the Chisa series (Ferna, White). Holds six patents.
A unique special processed lactic acid bacteria material from Nichinichi Pharmaceutical that combines the characteristics of both FK-23 and LFK. Used in Protesan Every II.
