Development Story

We have been researching the "hot spring cure effect" of Beppu Onsen for many years.

During this research process, we discovered a new species of hot spring algae, "Onsen-Sourced Algae RG92." By accumulating data, including clinical trials on humans, we have gained many customers who have enjoyed our products, primarily skincare items.

During this time, we received many requests from customers asking, "Don't you have an ingestible RG92?" or "It seems like it would be good to take it internally." Leveraging the versatility of Onsen-Sourced Algae RG92's form, and with the establishment of scientific evidence through joint research with national institutions and universities, we are now proud to deliver it in the form of a supplement.
