Technology that realizes the three principles of health

Ganoderma lucidum is a mushroom that has a hard tissue and cannot be eaten as it is.

For this reason, people have traditionally brewed it to extract useful ingredients.
In order to extract the active ingredients, the "hot water extraction method", which boils down the ingredients in boiling water, and the "alcohol extraction method", which extracts the ingredients while soaking in alcohol, are generally used even today.

However, with these two methods, only about 8% of the total useful components can be extracted from the hard tissue of Ganoderma lucidum. There was no choice but to throw away the useful ingredients remaining in the remaining 92%.

Breaking through such a status quo, we adopted an epoch-making extraction technology that could not be achieved with conventional extraction technology, and made it possible to extract at an extraction rate of about 40%, which is five times the conventional extraction rate.

This extraction method uses almost no heat, and by applying pressure in several steps, it is possible to extract without damaging the useful ingredients, so it was named "circulating multi-stage pressurized extraction method".


With this technology, our supplements contain extracts that are packed with useful ingredients. 

3 conditions
for good health

Since our establishment in 1981, we have been in contact with many customers nationwide.
In addition, he previously operated a private non-profit organization (NPO) "Clinical Study Group for Psychosomatic Medicine" (currently inactive) that researches integrative medicine, and has interacted with many doctors. derived the conditions.

"Three conditions for health" refers to blood, intestinal environment, and immunity. The three main functions of blood, intestinal environment, and immunity are as follows.

function of blood

1. Deliver fresh oxygen and nutrients to every corner of cells and collect waste products.
2. Carry white blood cells (immune cells).
3. Maintain body temperature by spreading warm blood to every corner of the body.

Functions of the intestinal environment

1. Absorb nutrients and water.
2.Excrete waste products from the body.
3.Maintain the intestinal immune system, which accounts for about 60% of the human body's immune cells.

function of immunity

It eliminates foreign substances such as bacteria and viruses that invade the body and suppresses the proliferation of cancer cells.

Many diseases are caused by the deterioration of one of these three functions.
In other words, our philosophy at Joyaku Research Institute is that if your blood, intestinal environment, and immunity are normal, you will be able to lead a healthy and fulfilling life.
