Ru Institute has continued research and development of fish scale collagen, the main component of fish scales, and has succeeded in developing the world's first technology for extracting collagen from fish scales. Fish scale collagen differs from conventional single collagen because it is a novel complex that contains several percent of chitin, an amide derivative of glucose, in addition to protein. This complex functions as a soil that energizes cells and improves immunity, which in turn helps to maintain good health on a daily basis.

The collagen developed by RU Institute is a nano-sized collagen extracted from fish scales, which is easily absorbed by the human body. It is an ultra-low molecular collagen with enhanced absorption. Its 100% domestically produced ingredients are carefully selected at our own factory and processed as collagen without adding any extra substances.

The collagen production method adopted by RU Institute is the only method that can produce collagen in a super-reduced aqueous solution with excellent digestibility and absorption. Because no chemicals are used, safe and pure collagen can be extracted. The manufacturing method removes lipids, so calories are reduced, and the unique smell of fish collagen is minimal, making it possible to drink the undiluted solution as is.
