Circadia vs.
Nuun.

A clean, low-sugar electrolyte tablet that does one narrow thing well. We do the broader, time-aware job it never set out to do.

Nuun is made by Nuun (Nestlé).

Where the gap opens
01

Electrolytes are not nutrition

Replacing salts is useful when you are depleted and does nothing for the vitamin D, choline and magnesium gaps in ordinary diets. We dose those directly, in absorbable forms.123

02

The vitamins it adds are the easy ones

A little B and C ride along, the water-soluble nutrients most people already get. The surplus simply leaves your body. We spend our formula elsewhere.45

03

No sense of when

One tablet suits any hour. RISE and DRIFT are tuned to two specific ones.6
