An iced matcha latte with many small piles of ingredients in front of it.
An iced matcha latte with a few ingredients in front of it.

01 · THE USUAL WAY

A pinch of everything.

Many blends pack a long list of ingredients into one scoop. That sounds generous, but a pinch of each may be too little to matter.

02 · THE ONDO° WAY

Enough of what matters.

We went the other way. Each cup has only what it needs, with the key ingredients at amounts used in clinical studies. Every amount is listed.

What is ONDO°

ONDO is the Korean word for temperature. 
Not the number on a thermometer.
