Which is better, Russian or Hokkaido chaga?

The most important characteristic of chaga is the outstanding SOD enzyme, but the actual amount of SOD enzyme in chopped chaga is lower than Agaricus and coral yamabushi mushrooms, which is about 1000 units of SOD enzyme. In Rite, we have detected more than 40,000 units of SOD by our own method of manufacturing chaga using a patented method. We will spare no effort to bring out the charm and characteristics of the chaga rather than saying which region is better.

I've heard that chaga is good for diabetes, does it work?

Chaga has the characteristic of inhibiting AGEs, but the results of the Food Analysis Center showed that the inhibition of AGEs when ordinary chopped chaga was boiled was less than 10%. At Rite, we process our products with the aim of achieving an AGEs suppression of IC 50 or higher, but this is not a therapeutic goal, and we are only trying to make the most of the natural benefits of chaga. Chaga is a health tea made from natural ingredients.

I've heard that chaga is more nutritious in the outer black part of the chaga, but from which part of the chaga is the rite made?

Chaga product description in China says that the outer black part is more nutritious and expensive than the inner brown part, but the mushrooms have hard cell walls that make it impossible to extract the nutrients contained inside normally. Rite uses a patented process to break down the cell walls and extract all the nutrients in the chaga cells at high concentration, providing you with a product featuring over 40,000 units of SOD enzymes, beta-glucans and AGEs inhibition over IC50, regardless of whether you are on the outside or inside.
