Spring has arrived across Canada — and with it, longer days, warmer temperatures, and a welcome return of natural sunlight. For seniors and their caregivers, this seasonal shift is more than just a mood lifter. It is one of the most important opportunities of the year to address one of the most common — and most overlooked — nutritional deficiencies in older adults: vitamin D deficiency.
At Corelia Health, we work with families across Ontario and beyond to support aging loved ones with compassionate, expert-guided care. This spring, our clinical team wants to share what every caregiver should know about vitamin D — why it matters, how to help, and what Health Canada recommends.

Why Vitamin D Is So Critical for Seniors
Vitamin D is often called the “sunshine vitamin” — and for good reason. Our skin produces it naturally when exposed to sunlight. But as we age, the body becomes significantly less efficient at this process.
Combined with Canada’s long winters and the tendency for older adults to spend more time indoors, vitamin D deficiency is extremely common among Canadian seniors — and many don’t know they have it.
According to Statistics Canada, vitamin D deficiency and insufficiency remain prevalent across the country despite national supplementation guidelines.
Health Risks of Vitamin D Deficiency
Spring Guidance: Get Your Loved One Outside Every Day
The single best thing you can do right now is simple: get your loved one outdoors. Even brief, gentle exposure to spring sunlight can help the body begin producing vitamin D naturally. We recommend aiming for 15 to 20 minutes of outdoor time daily, ideally in the morning when light is soft and temperatures are mild.
Easy ways to make outdoor time a daily habit:
• A short morning walk around the block or local park
• Sitting on the porch or balcony with a cup of tea
• Light gardening or tending to plants outdoors
• A calm afternoon visit to a green space or garden
Boost Vitamin D Through Food Too
Outdoor time alone may not be enough, particularly on cloudy days or for seniors who spend most of their time indoors. Including vitamin D-rich foods in your loved one’s daily meals is a reliable and easy complement to sunlight.
Best food sources include fortified milk and dairy, fatty fish (salmon, sardines, trout), egg yolks, fortified cereals, and canned tuna.
Health Canada’s Supplement Recommendations
⚠️ Important: Please consult your loved one’s physician or pharmacist before starting or adjusting any vitamin D supplement.
Key Takeaways
Sun Exposure
15-20 minutes of morning sunlight helps natural production.
Rich Foods
Salmon, eggs, and fortified dairy are excellent sources.
Daily IU
Ensure 400-800 IU daily as per Health Canada guidelines.
Blood Test
Ask your GP for a vitamin D test to confirm levels.
Small, consistent health habits like daily outdoor time and proper nutrition may seem simple, but their long-term impact on your loved one’s quality of life is significant.
