Circadia vs.
Flow.

Clean Canadian spring water with a light flavour and an alkaline story. We are glad it exists. It is hydration with a halo, not a formula, with no targeted nutrients and no sense of the hour.

Flow is made by Flow Beverage Corp.

Where the gap opens
01

The alkaline story is a halo

A pH around 8.1 sounds meaningful, but your stomach is strongly acidic by design, so the pH of a drink does little once you swallow it. The water is fine. The wellness framing is doing more work than the water is.

02

Hydration is the floor

Naturally occurring minerals are pleasant and not the same as dosing the vitamin D, choline and magnesium gaps common in Canadian diets. We target those on purpose, in absorbable forms.123

03

No clock, no function

Flow is one carton for any hour. Circadia is two cans built for the two ends of your day, RISE to climb and DRIFT to wind down.4
