As a pharmacist, I can confidently propose quality products to customers. I appreciated the advice, including market analysis, when discussing the expansion of sales channels.
Industry: Pharmacy, Pharmacist, Writer
Reasons for selection
From my perspective as a pharmacist, I seek to provide customers with ingredients that are safe and reliable, and that I can confidently recommend. From the beginning, I wanted to use NMN produced through the yeast fermentation method. Given that NMN products of varying and questionable quality are circulating, it was crucial to us that the product undergo third-party testing, proving its high quality, high purity, and high stability.

Our company’s response from order to delivery

They were able to support us in the fastest possible time to test and sell the product. The quality level is really high and solid compared to the big companies.
Industry: D2C (regular mail order) health food consulting and web marketing
Reasons for selection
There are three reasons. First, the minimum order quantity was small. With other companies, we would have to order at least several thousand units, so being able to proceed with small lots during test sales was attractive. Second, the quality standards were very high. Since the product uses domestically produced ingredients and the yeast fermentation method, it was very easy to use this as a selling point. Third, the price. When compared to other companies, it was relatively not expensive.
However, the quality level is really high and solid, including quality control and test contents that are not inferior to those of large companies, and we judged that the price is lower overall compared to other companies. Of course, if we asked a large company, they would have such quality standards, but we really liked the fact that they were able to respond flexibly with not too many lots while conducting test sales.
Handling from order to delivery
Nothing was really perfect. It was really very easy to work with. The delivery was really fast, about a month, and if we are going to keep re-ordering again and again, it is really important to have a lot going on without delays, and I am glad that the business schedule was really accurate. The package design was also very sophisticated, and the fact that you were able to carefully work to a certain standard of creativity and bring it to the test market as quickly as possible was very helpful.
