…so we can be proud to give each one to our own family.
It started with a father’s habit.
Every morning, Calvin Chan watched his father take his soy lecithin and fish oil. Small habits, kept for years.
In 1999, after university in America, Calvin started CATALO with one rule: nothing artificial.
CATALO stands for natural. That is our core value.

Always American made, from the first bottle.
We want to know exactly what goes into everything we make.
So CATALO is made in cGMP facilities registered with the FDA, and checked by our own quality team.
What goes in comes from nature:
- Vitamin C from acerola cherries
- Calcium from Icelandic red algae
- Lutein from marigold flowers
And from the start, these American-made formulas crossed the Pacific to families in Hong Kong. There, our name even came with an extra word in front: America’s.

Families could tell the difference.
In 2003 we opened our first shop, in Hung Hom, Hong Kong. It’s still open today.
They chose CATALO like any family would: for the quality.
