Coral and hydrogen are major forces which support our daily activities
Coral minerals and hydrogen have great potentials to improve the quality of our lives.

Corals began their lives in the ocean 3.5 billion years ago, and their bodies were created through chemical reactions called metabolism, which breaks down and synthesizes organic molecules taken in as nutrients. It is a dynamic entity that sustains the body and supports its activities.
The reactions are smoothly facilitated by proteins called enzymes. Throughout the long history of life, enzymes have evolved a way to use ocean minerals as cofactor and keep metabolism running fluently. Trace minerals are thus essential for the enzymes to be activated.
Degradation of the metabolic facilities and equipment of cells is inevitable with this life activity. One of the causes of accelerated deterioration is oxidative stress and antioxidants are needed to prevent and repair the deterioration. Hydrogen has attracted a lot of attention as an ideal antioxidant.

The combination of coral minerals and hydrogen is a requirement for maintaining a stable life activity.

Coral minerals have been contributing to our health for 35 years as a mineral supplement. Newly announced hydrogenated coral mineral, which is hydrogen added to coral minerals, has been welcomed by many people as our health supplement.

Coral and hydrogen are major forces that support our active lives by smoothly promoting the metabolism, which is the life activity itself in daily life, and preventing the deterioration and damage to the body due to daily oxidative stress.

It is expected to have various possibilities as a food material based on the food history and the various health effects are reported from it. In the future, we would like to accumulate more data as observational studies, and conduct more rigorous clinical evaluations.

Hydrogen as an antioxidant

In addition to the fact that hydrogen is the smallest molecule which could be distributed anywhere in the body, it has been revealed that it specifically reacts with the most toxic hydroxyl radical among active oxygen. Basic researches and clinical applications on biological antioxidant defense are in progress.
For example, in addition to being a tissue with a high lipid content, the brain is in an environment where oxidative stress is likely to occur. This is because active oxygen is easily produced from neurotransmitter molecules. However, since the brain has a mechanism (blood-brain barrier) that protects the brain from passing only what is necessary, it is a tissue where exogenous antioxidant molecules are hard to work. It has been reported that hydrogen, which is a small molecule, is effective in treating cerebral infarction because it easily penetrates into the brain. Another characteristic is that hydrogen reacts with hydroxyl radicals to produce only stable and harmless H2O.

Ref. Minerals, Hydrogen and Hydrogenated Coral Minerals

Over the years, Okinawa Sango Co., Ltd. has been working on hydrogen, which is likely to be involved in oxidative stress and inflammation. We have commercialized it in the form of food and water. Through research with experts in a wide variety of fields, the raw material for foods [hydrogenated coral minerals] Sala was born. In addition, a supplement called Suiso-mo Sango-mo, made from Sala, has been completed.

We are actually experiencing that using hydrogen for people and plants can make a huge difference in maintaining the health of people and crops. As a specific example, foliage plants such as adiantum have shining buds even in the winter, and have become glossy and beautiful. A florist was surprised to see it as it was totally different to others. In addition, a lady who had been drinking our coral and hydrogen water said with a smile, “It feels like a dream to get back my usual life routine!”
Although no clinical trials have been conducted, it is said that hydrogen has no harmful effects, so we hereby propose it.

We started OEM contract manufacturing as we hope that the hydrogen supplement Suiso-mo Sango-mo will be more widely known in society. We will continue to share information which will help improving the physical condition of many people both in Japan and overseas. We thank you in advance.
