Circadia vs.
Prime Hydration.

A zero-sugar hydration drink built on sucralose, a marketing budget and a plastic bottle. We use a little real sweetness and dose nutrients you can actually use.

Prime Hydration is made by Prime.

Where the gap opens
01

Zero sugar, by way of sucralose

No sugar is good. Reaching it with a heavy synthetic sweetener is a trade we did not want to make, so we sweeten lightly with real juice and a touch of organic cane instead.1

02

Hydration is the floor, not the feature

Electrolytes and a few BCAAs cover the basics. They do nothing for the vitamin D and choline gaps common in ordinary diets, which is exactly what we target, in absorbable forms.23

03

Built on attention, sold in plastic

Prime was engineered to trend, not to fit your rhythm, and the plastic bottle adds microplastics to every sip. Circadia is two cans for two halves of the day.45
