Basing his conclusions on clinical data from more than 300,000 patients, Dr. Shinya, an authority in the field of gastrointestinal endoscopy, believes that enzymes are the key to health. Using this knowledge, and after much trial and error, an enzyme supplement using active enzymes—Yoru Osoi Gohan Demo (Late Night Meal)—was created under his supervision.

An enzyme’s main job is to encourage metabolic activity, and to aid in the breakdown of food and the absorption of nutrients. Recent gastrointestinal studies have shown that gut health has a profound impact on overall health, affecting hormone secretions and autonomic nerves, as well as brain and skin health. As a result, more people are focusing on creating a healthy gut. Yoru Osoi Gohan Demo, which does just that, enjoys wide popularity among women in their twenties, thirties, and forties.

All of the products in the Yoru Osoi Gohan Demo series of enzyme supplements are made with active enzymes produced by fermenting several kinds of grain with koji (Aspergillus oryzae). The vast majority of enzyme drinks currently sold in stores are subject to heat sterilization prior to bottling, a process which renders the enzymes useless. Enzymes are sensitive to high temperatures, and if heated above 70 degrees Celsius they lose their effectiveness. As a result, it is impossible to reap the benefits of enzymes by consuming drinks containing heat-treated, inactive enzymes.

Meanwhile, Yoru Osoi Gohan Demo enzyme supplements come in tablet form. In this way, the enzymes remain active and are able to break down lipids, carbohydrates, and proteins, thus compensating for enzymes in the gut that have diminished with age.

Shinya Koso’s most popular line of products is the Yoru Osoi Gohan Demo series of enzyme tablets, which includes the original variety in blue packaging, the Omori turmeric blend, the Gold variety with extra enzymes and turmeric, and the newest offering, Nemutteru Aida Ni (While You Sleep), which was launched in March 2019.

Best-selling is the Gold variety, which is packed full of extra enzymes. However, it is recommended that you choose the variety that suits your needs based on the condition of your body and your plans for the day.

For those who indulge in generous servings of food and drink on a regular basis, the Omori turmeric blend, in brown packaging, is the best choice. A natural compound, turmeric has been found to dramatically boost the body’s antioxidant capacity and also supports the breakdown of alcohol in a way that protects against liver damage.

Looking forward to a night of feasting? Then grab a package of Gold tablets, which contain 160% of the enzymes of the original Yoru Osoi Gohan Demo.

Gold is the most popular variety in Japan and the rest of Asia. Compared with the original tablets, packaged in blue, which can break down the carbohydrates from 14.7 bowls of rice, the Gold variety can break down the carbohydrates from a whopping 28.51 bowls of rice. (Results are from Shinya Koso in-house experiments carried out in bowls, and not experiments using the human body.)

Choose your Yoru Osoi Gohan Demo variety—original, Omori, or Gold—based on your intake of food for the day. All three varieties enjoy a great deal of popularity.

Released in March 2019, Nemutteru Aida Ni (While You Sleep) is the latest in the Yoru Osoi Gohan Demo line to enjoy the spotlight. Popular in Japan among female office workers and housewives, Nemutteru Aida Ni gives these busy women a chance to take care of themselves while they sleep to make up for not being able to do so during their hectic days.

The product is based on an entirely new concept of promoting the burning of fat during sleeping hours. In addition to containing active enzymes, which promote the digestion of food, Nemutteru Aida Ni boasts a list of ingredients that includes arginine, an amino acid that promotes the secretion of growth hormones, as well as glycine and GABA (gamma-aminobutyric acid), both of which facilitate relaxation.

With Nemutteru Aida Ni, while your gastrointestinal tract rests, your body will have a chance to restore itself as you enjoy a good night’s sleep. Perfect for those struggling with jet lag, and for those who wish to enjoy the local cuisine while traveling in countries with vastly different food cultures, Nemutteru Aida Ni is a must-buy if you find yourself in Japan.

Regular Shinya Koso customers have shared the following:

“Taking enzymes has meant that I’m able to wake up refreshed after a good night’s sleep.”

“The tablets being packaged separately means that I can carry them with me in my bag, which makes it easier to remember to take them.”

“In addition to eating a healthy diet, taking Shinya Koso helps me maintain good long-term health.”

After trying Nemutteru Aida Ni, the writer of this feature had the following to say:

“I was able to sleep very soundly, my stomach didn’t feel full after eating, and I was able to say sayonara to sluggish mornings.”

One of the wonderful qualities of the Yoru Osoi Gohan Demo line is how quickly customers are able to feel the effects of taking the enzyme tablets. It’s also a comfort knowing that Yoru Osoi Gohan Demo products are developed under the supervision of a medical doctor, providing customers with peace of mind even when trying new products in the line.

I’ve tried other supplements, but the fast-acting nature of Yoru Osoi Gohan Demo has won me over. From now on, I’ll be choosing Yoru Osoi Gohan Demo.
