Rooted in Korea,
Backed by Science
We believe optimal health is a lifelong practice. Drawing on Korean botanical traditions and the precision of modern science, we create supplements that truly perform.
Born from a mother's pain, and a daughter's obsession
Sam Yun Lee grew up surrounded by plants.
As a Teen, she spent hours in her grandmother's garden in Korea — learning the names of roots, memorising which leaves were medicinal, understanding intuitively that nature held answers that modern life had forgotten.
But it wasn't until her mother fell ill that those answers truly mattered.
When conventional medicine offered little relief — the symptoms persisting, the side effects accumulating, the hope quietly fading — Yun Lee refused to accept that this was all there was. She began researching obsessively. Pulling studies. Tracing ancient herbal formulas back to their origins. Cross-referencing centuries of Korean and Eastern botanical medicine with the latest nutritional science.
She found what the research labs already knew but nobody was talking about: that the right plant compounds, at the right dose, in the right form, could do what pharmaceuticals could not.
Her mother began to feel better.
And Seoyun was born.
