Where the gap opens
01

A nicer packet, same premise

Around 1000 milligrams of vitamin C is still far past what your body can use at once, and the surplus is excreted. We give Ener-C credit for a clean label, then dose nutrients that actually accumulate to effect.1

02

Two Canadians, different aim

We are glad to share a country. Our formula targets vitamin D, choline, magnesium and glycine, the gaps with the strongest case, in absorbable forms, rather than topping up vitamin C most people already have.234

03

Still no clock

A packet fits any moment, so it fits none in particular. RISE and DRIFT are designed for the two ends of your day.5
