Polyglutamic acid Beauty/beautiful skin effect

It has a high detoxification effect such as facilitating the egestion of waste products.

Polyglutamic acid　is the main component of sticky pastes of natto, and is a natural amino acid polymer with the glutamine acid - one of the amino acids - combined in a straight-chain-like-shape. Being very difficult to dissolve, this polyglutamic acid protects the stomach wall and facilitates the egestion of toxic substances for our body such as waste products in the intestinal tract. In addition, polyglutamic acid contains a blood clot dissolving enzyme called “Nattokinase” which we will explain later.

It enhances the intrinsic moisturizing function of our skin.

Acid is also known to have the beauty effect on skin. These days, in the cosmetic section of department stores, they have the products with polyglutamic acid such as natto soap and natto lotions which attract interest of consumers. The following are their two main features:

1. Protect the skin by creating membranes on its surface; and
2. Increase natural moisturizing factors such as amino acids by revitalizing cells inside the skin

Natto’s polyglutamic acid not only protects the skin but also enhances the intrinsic moisturizing function of our skin. People who are suffering from chapped skin or dry skin can recover the function of their skin by using the products with polyglutamic acid such as natto lotions.
