Shinya Koso Night Diet is a weight loss supplement manufactured by a Japanese company called Imomoko. The product is sold in the form of a powder instead of a pill like a tablet or capsule. That said, once the powder is mixed with a liquid and swallowed, the concept is quite similar to other nighttime weight loss supplements.
According to the official website for this product, this product can be taken as a tablet with lukewarm water or it can be enjoyed as a drink instead of a person’s regular evening tea. It is not entirely clear what that is supposed to mean as the product is a powder, not a tablet. It could very well be that the website was originally written in Japanese and poorly translated, leading to this confusing statement, though that is not evident.
That said, the manufacturer does state that the best way to use this product is in the form of a tea, so for people who do want to get the most out of this product, it can be easy to overlook the rather confusing mention of using the product as a tablet instead and to simply follow the directions of preparing it in warm water and consuming it as a tea.
The official website for this product does not offer any suggestion of scientific evidence to support the use of the formula as a whole, nor does it break down its formula into individual ingredients that have cited research to support their use, either. Still, it claims that it should be taken in the evening so it can trigger fat loss in the body overnight while preventing fat buildup.
The main ingredient in Shinya Koso is an enzyme called nattokinase and the formula does contain other natural ingredients but the information offered regarding why those substances were chosen and whether or not they are safe or produce potential side effects is absent from official information sources.
The nattokinase in this product is the central active ingredient around which the rest of the formula was designed. It is not well understood and very little research has been conducted on it, particularly when it comes to its potential impact on fat loss.
Other ingredients in the formula are listed as “raw materials” and are identified as follows: Aspergillus oryzae extract, oligosaccharide, rice malt powder, papaya products, dextrin, Garcinia Cambodia, turmeric extract at the end of the ginger extract, yeast (containing zinc), powdered cinnamon, peppermint powder coagulans, α-lipoic acid, l-carnitinfmar acid salt, black pepper extract, citric acid, microcrystalline cellulose, stearic acid Ca, silicon dioxide, folic acid, (part of the raw materials including wheat).
Each package of Shinya Koso contains 30 powder packets, which provides enough for a full month’s supply. At the time of the writing of this review, the retail cost for this product was $28.00, which is slightly expensive in the powder and tea category of the weight loss marketplace. Moreover, shipping charges should also be taken into consideration when tallying the daily cost of using this product.
