Canada sits far enough north that sunlight alone doesn't produce meaningful vitamin D for a good part of the year — which is why vitamin D3 is one of the most commonly supplemented nutrients here. D3 supports the maintenance of healthy bones and teeth, calcium absorption, immune function and muscle function. Shop softgels, liquids, sprays and D3 + K2 combinations.

Vitamin D3 FAQ & Buying Guide
Why do Canadians supplement vitamin D?
At Canadian latitudes the sun sits too low from roughly October through March for skin to synthesize much vitamin D, and indoor work limits it the rest of the year. Health Canada recommends a daily supplement for most adults, which is why D3 is a year-round staple in a lot of stacks.
What's the difference between D2 and D3?
D3 (cholecalciferol) is the form your skin makes from sunlight, and it raises and maintains blood levels more effectively than D2. Everything in this collection is D3.
Why is vitamin D3 often paired with K2?
D3 improves how much calcium you absorb; K2 (MK-7) helps direct that calcium into bone rather than soft tissue. The two work as a pair, which is why D3 + K2 combinations are so common.
Softgels, liquid or spray — does it matter?
Not much for absorption. Vitamin D is fat-soluble, so take any format with a meal containing some fat. Choose on convenience: softgels for simplicity, liquids and sprays if you dislike pills or want to fine-tune the dose.
