Immunity Supplements

Your immune system handles a ridiculous amount of work without you noticing โ€” until it doesn't. A cold knocks you out for a week, or that bug going around the office finally catches up with you. That's usually when people start thinking about immune support.
Immune supplements provide the vitamins, minerals, and plant compounds your body's defense system relies on. Vitamin C, vitamin D, zinc, elderberry, echinacea, and medicinal mushrooms like reishi are some of the most common ones you'll see in this category.
What You'll Find Here

We carry everything from basic vitamin C capsules to multi-ingredient immune formulas. Some are designed for daily maintenance โ€” the kind of thing you take year-round. Others are meant for acute use, like when you feel a cold coming on and want to throw everything at it.


Who Are These For?

People who catch every bug that goes around. Frequent travellers, anyone heading into cold and flu season wanting a bit of extra insurance. Parents whose kids bring home germs from school or daycare.


A Few Things Worth Knowing

Vitamin D is worth testing for โ€” a lot of Canadians are low, especially in winter, and it matters more for immunity than most people realize. Zinc works best when you start it early in an illness. Daily habits matter too: sleep, stress management, and not skipping meals all affect how well your immune system performs.
