Four roots, one purpose

Traditional Korean medicine cabinets keep each herb in its own drawer. K-TONIC works the same way — four time-tested botanicals, each doing one job well.

Tap a drawer to open it.


  • Acorus gramineus (Shí Chāng Pú, Grassleaf sweetflag rhizome): Supports brain function, mental clarity, and cognitive focus.
  • Epimedium (Yín Yáng Huò, Epimedium leaf / Horny goat weed): Helps support yin-yang balance, vitality, and physical stamina.
  • Angelica sinensis (Dāng Guī, Dong quai root): Supports healthy blood nourishment and circulation.
  • Cornus officinalis (Shān Zhū Yú, Cornus fruit): Helps support kidney and liver health and maintain overall vitality.


K-TONIC "Replenish Energy" is a premium herbal medicine that protects the health of all generations regardless of age, including promoting vitality in the elderly, strengthening the energy of busy middle-aged men and women, restoring physical strength in the younger generation exhausted from stress, and improving concentration in students exhausted from studying.



  • Seniors: "Supports memory and promotes vitality"


  • Patients: "Supports the body's natural renewal process"


  • Men: "If you're exhausted from chronic fatigue, don't hesitate any longer"


  • Women: "From menopause to beauty, complete a woman's elegance"


  • Students/Children: "Supports cognitive performance and immune health"

Built for Real Life


Forget the bitter brew. This is one pill, anywhere, anytime.


Traditional tonics meant boiling roots for hours and choking down the taste. K-TONIC compresses the same formula into a capsule — no smell, no prep, no excuses.


1. Take one capsule with a glass of warm water.


2.  No brewing, steeping, or measuring required.


3. Fits in a bag, a desk drawer, or a carry-on.
