SALMON NASAL CARTILAGE
Salmons were once an important protein source in Japan, especially in the area where salmons
were caught in abundance.
We, Japanese have been eating salmon nasal cartilage, which is also called “Hizu”, since a long,
long time ago. This means that we have taken proteoglycan in salmons as a food.
SCIENTIFIC EVIDENCES
Not only historical background, but also scientific evaluations show the safety of proteoglycan.
