The spirit embodied in the name "Supplement Craftsman" is uncompromising exploration and dedication to exceptional technology.
In 2003, he aimed to develop "supplements that exceed the market supplements" and started his business in earnest as a fabless manufacturer. We have launched our own product "Manavie". Since then, it has been improved over the past 20 years, and in May 2023, the 4th generation and 20th anniversary edition were launched.
Our product development is based on the type, grade, and amount of ingredients of each material to find the best combination. We are particular about the materials of granulation and capsules, and we also conduct thorough collapse tests. In addition, for hygiene reasons, we have designed packaging that does not require touching the contents with your hands, and by dividing them into small bags for each recommended amount per day, we take care to ensure that you can eat them cleanly and with peace of mind at any time.
Most importantly, the following questions are asked:
・If you and your family were to take it, is this really the best?
・Is the finish satisfactory?
・Is it a product that you would recommend to your loved ones?
We only deliver products that can confidently answer "YES" to these questions.
Our products are manufactured in a GMP-certified factory of the Japan Health and Nutrition Food Association (Nikken Eikyō). This GMP product mark is proof that it adheres to the guidelines of the Ministry of Health, Labour and Welfare, is manufactured safely, and maintains a certain level of quality. As of August 2025, we are proud to note that only 113 products with the GMP product mark are listed on the Nikken Eikyo — including products from "supplement craftsmen."
