Kobon Marvel First Yeast is a health beverage developed in 1950 (Showa 25) focusing on "natural yeast," an ingredient used in ancient Japanese fermented foods. It aims to supplement the "natural yeast" that modern people tend to lack.
This product is made by collecting wild natural yeast that inhabits the atmosphere and green leaves of the Amagi Mountains in Izu, Shizuoka Prefecture. The yeast is simply attached to several types of fruit and naturally fermented, successfully promoting the growth, strengthening, and ripening of the bacteria. It is a plant extract fermented beverage rich in powerful natural yeast born from the wild.
In recent years, many health drinks using a variety of raw materials have been sold, but we prioritize cultivating beneficial yeast with just a few compatible fruits rather than dozens of ingredients. For over 60 years since our founding, we have been traditionally cultivating natural yeast vigorously and shipping it.
Please utilize "Natural Yeast that Supports Japanese Health" for the health of your family.
◆ Features of Kobon’s Natural Yeast Drink
1. Easy supplementation of necessary natural yeast for Japanese people
The beneficial bacteria that Japanese and Westerners mainly favor differ. We believe that Westerners mainly need lactic acid bacteria related to preventing meat spoilage, while Japanese need natural yeast that helps ferment and break down grains and vegetables, making fibers easier to eat. This product is a plant extract fermented beverage that allows easy intake of this natural yeast.
2. Natural yeast resistant to acid, salt, and heat
Fully ripened natural yeast, taking about 1 to 1.5 years, is resistant to acid, salt, and heat, and can be used in cooking.
3. Fermentation honey born from natural yeast
Kobon’s natural yeast drink contains about 15 to 35 times (depending on the country of origin and type of honey) the amount of natural yeast compared to pure honey (natural honey without artificial additives). Its sweetness is derived from directly reducing sugars, the same as pure honey. You can enjoy fermented honey produced by natural yeast.
◆ Sugar content: Kobon Marvel 56°–58°, Kobon 66°, Honey 70°–75°
4. No food additives
Kobon’s natural yeast beverage is a fermented food (fermented drink) that contains no additives (coloring agents, preservatives, artificial sweeteners, etc.). Since it is also used by small children, we regularly conduct tests for radioactive substances.
5. Supporting family health through food
Kobon’s natural yeast drink can be enjoyed by everyone from infants to the elderly, regardless of age or gender. Unlike honey, there is no risk of botulinum bacteria. It is made from fruit, easy to drink, and continues to be popular.
≪Recommended for≫

◆ The Work of Kobon’s Natural Yeast
Kobon’s natural yeast differs from bacteria like lactic acid bacteria; it has a nucleus, is genetically stable, and primarily uses sugars like glucose as an energy source.
◆ A Habit to Continue for Smiles and Family
Dilute 20 ml of the original liquid with water or hot water, about 6 to 7 times. Drink once to three times a day as a guideline.
One bottle provides approximately 26 servings.
It contains no additives (coloring agents, preservatives, artificial sweeteners) and is caffeine-free, so it can be enjoyed by everyone from 0 years old to the elderly.
The flavor is fruity and honey-like, making it easy to continue drinking as a delicious juice.
◆ How Natural Yeast Works to Increase Enzymes in the Body
Recently, the topic of "enzymes" has gained attention.
Enzymes are vital nutrients that contribute to vitality and achieving ideal skin, but they are living organisms—yeast bacteria—that form the basis of these enzymes.
Many ask about the difference between yeast and enzymes: enzymes are substances, whereas yeast are living organisms (living creatures).
Yeast also produces and increases enzymes, serving as raw materials for enzyme creation.
Japanese people have traditionally valued fermented foods to prevent food spoilage (for storage). However, the intake of fermented foods has been decreasing year by year.
As a result, the body cannot properly ferment what is eaten, leading to spoilage, which causes issues like foul-smelling gas and stool, and fatigue.
Your beneficial bacteria in your gut = yourself.
Kobon Marvel is based on natural yeast collected over 50 years ago. It is a proven, highly effective strain.
