Circadia vs.
BioSteel.

Genuinely clean: zero sugar, no dyes, NSF tested, Canadian, and relaunched and growing under new owners. The gap is depth. It is mostly electrolytes and a few B vitamins, where we match the electrolytes and add the nutrients that actually move the needle.

BioSteel is made by BioSteel (Coachwood Group).
The scorecard
8 / 14 dimensions where Circadia leads BioSteel. Matched on the rest.

Where the gap opens
01

Clean, but thin

Strip it down and BioSteel is electrolytes plus a handful of B vitamins. We carry a comparable electrolyte profile and then keep going, adding vitamin D, choline, magnesium glycinate, glycine and L-theanine. Same clean floor, far more function.12

02

The B vitamins you mostly excrete

Its vitamin support leans on the B group, which is water-soluble and rarely deficient. We spend our formula on the gaps that actually show up, in forms that absorb.34

03

Clean, but undirected

One all-purpose hydration formula has no view on when you drink it. Circadia is built around the daily cortisol curve, with RISE and DRIFT for each end.56

04

Two Canadians, one in plastic

We respect the home-team clean label and the NSF testing. The ready-to-drink bottles are still plastic, with the microplastics that brings; our can is aluminium.7
