HOW IT WORKS TOGETHER

Three drivers of aging. One daily system.

Aging isn't one problem — it's three. Each supplement in this collection targets a specific, well-studied mechanism so the stack works as a whole.

01

The frontline micronutrients

Vitamin C, vitamin D and zinc are the three nutrients your immune cells depend on most — and the three Canadian winters drain hardest.

TARGETED BY
Vitamin C · Vitamin D3 · Zinc
02

Antioxidant backup

Immune activity generates oxidative stress. Flavonoids like quercetin support your defences while helping manage the histamine response.

TARGETED BY
Quercetin
03

Botanical priming

Echinacea has been used for generations to support immune function — modern standardized extracts make the dose consistent.

01 · VITAMIN C + D3 + ZINC

Cover the big three

Vitamin D is the immune nutrient most Canadians are low in by February — we simply don't get the sun. Add vitamin C's antioxidant protection and zinc's role in immune cell function, and you've covered the foundation.

✓ Immune function · antioxidant protection · winter support

02 · QUERCETIN

The flavonoid your defences want

Quercetin is a plant flavonoid with well-studied antioxidant activity and a role in supporting a healthy histamine response — a smart year-round addition, especially through allergy season.

✓ Antioxidant · histamine support · immune resilience

03 · ECHINACEA

Prime the system

Echinacea is one of the most recognized immune botanicals in the world. A standardized daily extract supports your immune system's readiness through the months it's tested most.

First winter without going down

Two kids in daycare and I made it through the whole season. The D3 and zinc are non-negotiable in this house now.

Cheaper than the drugstore

Same ingredients, better doses, half the price of the brand-name stuff at the pharmacy. And it's actually made in Canada.

Questions, answered

Yes. Every supplement in this collection is manufactured in our Windsor, Ontario facility and batch-tested by a third-party lab before it ships.
Vitamin D3 is worth taking October through April at minimum — most Canadians can't make enough from sunlight in those months. The rest of the stack works year-round, with echinacea often cycled through the winter season.
Yes — they're designed as one daily routine, best taken with food. Zinc is gentlest on the stomach when taken with a meal.
