About our products

Fascinated by the charm of long-lived sharks, which live for more than 80 years, we have developed health food products specializing in rare domestic long-lived sharks with strong vitality, and we have received many customers with knotty problems who are pleased with our products.

Characteristics of our products

≪Kin-no-ho Kyoku" (Gold ear)

Contains plenty of non-denatured proteoglycan and non-denatured type II collagen, which are major components of cartilage cells in the body. Just one capsule contains 35 mg of non-denatured proteoglycan and 70.5 mg of non-denatured type II collagen, one of the largest amounts in Japan.

Researched and developed at Hirosaki University, a national university corporation, this is the first time in Japan that proteoglycans from an ancient Japanese long-lived shark have been successfully commercialized. The high content of proteoglycan, a cartilage component of rare domestic sharks, was proven to be 5.75 times more powerful than salmon proteoglycan used in common supplements through joint research with Tokyo University of Agriculture and Technology, and was patented on February 5, 2024.

Among more than 500 species of sharks, we have carefully selected the abalone shark, which is so vital and strong that three generations of fishermen say they are the only ones who have never seen bone deformities or cancer in any fish. One whole shark is used to produce one bag (60 grains) of Kaneho-no-Hokoku.

≪Izumo Pearl Rabbit Gold Oil Premium≫.

(1) Why are we particular about domestic long-lived sharks?

The blue tooth shark, which is said to be found only in the straits between Aomori and Hokkaido, has long been known as a long-lived shark that can live more than 80 years, and among more than 500 species of sharks, shark specialists have never seen bone deformities or cancer. While squalene is the main ingredient in foreign sharks, Kin-Oil domestic shark liver oil contains high levels of DPA, an intelligent component, and DAGE, a high-quality component for sleep, as well as DHA and EPA, which are also useful components.

(2) Safe domestic production

The product is manufactured at a top-level domestic factory certified as a GMP (Good Manufacturing Practice) manufacturing facility for dietary supplements, so you can take it with peace of mind.

(3) Four capsules provide DHA, EPA, and DPA equivalent to 12 slices of tuna!

The number of people who dislike fish has been increasing in recent years. By taking 1 to 4 capsules per day, depending on your constitution and lifestyle, you can take the blue fish ingredients that cannot be supplemented in your regular diet.
