For much of Japan’s history, the country has been marginalized due to the geographical nature of the country. Sitting on an island in the Asian sea, Japan has always had some barriers to expansion and it wasn’t until the modern era that naval power became powerful enough to allow Japanese to roam. Since then, they have been very successful, but with a large and powerful navy, trying to ensure they are healthy and getting good nutrition was difficult.
Around World War I Japanese scientists discovered and created a compound called sulbutiamine. This is a derivative of thiamine, which is supposed to help the brain to function better. Thiamin is a nutrient that is found in many different foods and helps brain function just like most other vitamins and minerals. The only problem is that our modern diet (and the Japanese especially) were very deficient in thiamin.
That made it really difficult to maintain a level of efficiency and health and worse, the thiamin was unable to cross the blood brain barrier. Japanese scientists discovered sulbutiamine, which is similar in structure, but crosses the blood brain barrier really easily and converts into thiamin so that Japanese sailors could benefit from this nutrient.
Without adequate thiamin humans could not survive and in many cases, we are deficient due to our poor diets. The only way to supplement this nutrient effectively is through the use of the Japanese compound sulbutiamine. Modern people are starting to use this Japanese brain invention as a “nootropic” or smart drug. Many people in important positions, such as Wall Street traders, doctors, lawyers, etc. are using it to finally get the right mental strength to be more successful and healthy.
