We are a mail-order company that has been selling health foods and health equipment in Yokohama for 30 years. We have been selling collagen in-house for more than 15 years, and we have specialized in selling our products for [knee joints] since the days when collagen was a beauty boom. We also did a double-blind clinical study to quantify the effect. As a result, there was a clear difference in knee discomfort, so we applied for a "food with functional claims" license, which was approved in 2022.
