Specializes in the research of pine nuts , and the precious SPN extract which is known to combat various cancers, viruses, and other infections. The pine nuts’ “pinolenic acid” is also a byproduct which can aid the skin by relieving inflammation, atopic dermatitis, and other allergic reactions.

HOME | About Proteoglycan

The cartilage regeneration promoting ingredient “proteoglycan” is being toted as the upcoming health and beauty material for the next generation.


“Proteoglycan” is a new material which restores joints and was discovered by the Joint Research Development of Hiromae University and Aomori prefectural industries. This was made possible by extracting high quality proteoglycan from the nasal cartilage of salmon. Not only does this extract apply to humans as well, but aids in bringing elasticity and moisturizing the skin. Additionally, proteoglycan works to recover skin damaged by UV rays, promote bodily metabolism functions, and improve joint arthritis and immune functions, which are highly anticipated in the medical field as well.


Regenerates cartilage and reduces joint pain

Proteoglycan prevents cartilage depletion in the knees, and cures any bone spicules which may be forming.

Collagen and glucosamine are important to support the nutrition of cartilage and maintain healthy elasticity, but cannot stop the formation of bone spicules.

Compared to other cartilage nutrition, it has more power to increase cartilage and control calcification.

Proteoglycan generates cartilage precursor cells and controls the depletion of cartilage. Also, by controlling the calcification of cartilage, it works for “decreasing cartilage” and “ectopic calcification”.

Showing the effectiveness for atrophic arthritis and osteoporosis



Proteoglycan produces young and elastic beautiful skin.

Proteoglycan supports the production of turnover skin, hyaluronic acid, and collagen. It also has a high water retention and is an indispensable ingredient for rough skin, wrinkles, elasticity of skin, as well as a melanin formation suppressant.

Keep young and fresh skin!

1 gram of hyaluronic acid can retain 6 liters, but proteoglycan has 1.3 times more moisture retention than hyaluronic acid.


It also rejuvenates the skin by activation metabolism.

Proteoglycan is an EGF (epidermal growth factor) like action, and adjusts the skin’s metabolism which declines with age.






Increase in water retention and wrinkle ameliorative.
Quantity of hyaluronic acid and collagen increase.


In the human examination that was held during winter, the season which degenerates wrinkles, an increase in the water content of thorn like substances by proteoglycan was shown. Also, water retention goes up, prevents dry skin, and lessens wrinkles.

Report summary of proteoglycan in Hiromae, Aomori

We visited Aomori prefecture to seek the raw ingredients of proteoglycan. We were able to hear various stories by meeting with people in Hiromae University laboratory who deal with proteoglycan at Aomori prefectural capital and Prefectural Regional Industry Support Center. Although it was a short trip, we had a productive and enjoyable experience with the warm and caring people in Aomori.



Aomori Proteoglycan Brand Promotion Council

The Aomori Proteoglycan Brand Promotion Council was established on June 1st, 2011 under the industry-academia-government collaboration. This council is making an effort to coordinate events, conferences, displays, and exhibits that improve the recognition of proteoglycan and the branding of Proteoglycan from Aomori PG.

NIPPON SUNSHOW is producing “flex PG” and “proteoglycan and non-denatured type-II collagen” that are recognized products of Aomori Proteoglycan Bran Promotion Council.
