Frequently Asked Questions
Where can I buy vitamin D supplements in Canada?

Why do Canadians need vitamin D supplementation?
Canada's geographic latitude means most Canadians cannot synthesize sufficient vitamin D from sunlight from October through April. Health Canada recommends supplementation for most adults during winter months. Multiple Canadian health organizations recommend at least 1,000-2,500 IU daily for adults.
How much vitamin D should I take daily?
Most adults benefit from 1,000-2,500 IU daily. Athletes and those with limited sun exposure may benefit from higher doses (up to 4,000 IU) — but always with healthcare provider guidance. Prairie Naturals Vitamin D3 2500 IU at $14.99 hits the standard daily dose for most users.
Vitamin D3 vs D2 — which is better?
D3 (cholecalciferol) is generally more bioavailable and effective than D2. All quality Canadian-market products use D3, including Prairie Naturals.
Should I take vitamin D with food?
Yes — vitamin D is fat-soluble and absorbs better when taken with a meal containing some fat. Most users take it with breakfast or lunch.
Can I get enough vitamin D from food?
It's difficult. Major food sources are fatty fish (salmon, mackerel), egg yolks, and fortified dairy. Most Canadians don't consume enough from food alone, especially in winter — that's why supplementation is so commonly recommended.
Does Top Nutrition & Fitness ship vitamin D to the USA?
Yes — we ship to all of the United States with no duties or tariffs.
