Vitamin D: Why It Matters and How to Know If You're Getting Enough

Vitamin D is often called the "sunshine vitamin" — and for good reason. Your body produces it when your skin is exposed to sunlight. But for millions of Canadians, especially during the long winter months, getting enough vitamin D from sunlight alone simply isn't possible. That's why vitamin D deficiency is one of the most common nutritional shortfalls in Canada, and why supplementation is so widely recommended.

What Does Vitamin D Do?

Vitamin D plays a critical role in several key functions in the body:

• Bone health: Vitamin D helps the body absorb calcium and phosphorus, which are essential for building and maintaining strong bones and teeth.
• Immune function: It supports the immune system's ability to fight off bacteria and viruses.
• Muscle function: Adequate vitamin D is associated with better muscle strength and reduced risk of falls in older adults.
• Mood regulation: Low vitamin D levels have been linked to low mood and seasonal affective disorder (SAD).
• Cardiovascular health: Emerging research suggests a role in supporting heart health, though more studies are ongoing.

Who Is at Risk of Vitamin D Deficiency?

While anyone can be deficient, certain groups are at higher risk:

• People living in northern climates (like Canada) with limited sun exposure for much of the year
• Older adults, whose skin is less efficient at producing vitamin D
• People with darker skin tones, which requires more sun exposure to produce the same amount of vitamin D
• Those who spend most of their time indoors
• People who cover most of their skin for cultural or medical reasons
• Individuals with conditions affecting fat absorption (vitamin D is fat-soluble)

How Much Vitamin D Do You Need?

Health Canada recommends 600 IU per day for adults up to age 70, and 800 IU for those over 70. However, many healthcare practitioners recommend higher amounts — particularly for those who are deficient or at risk. A blood test (25-hydroxyvitamin D) is the most reliable way to assess your levels and guide supplementation.

Always consult your healthcare provider before starting a new supplement, especially at higher doses.

Vitamin D in Liquid Form: Why It Can Be a Good Choice

Liquid vitamin D drops offer a few practical advantages:

• Easy to dose: Drops allow for flexible, precise dosing — useful when adjusting intake based on test results or practitioner guidance.
• Fast absorption: Liquid forms are readily absorbed, especially when taken with a meal containing healthy fats.
• Ideal for those who dislike swallowing capsules: A great option for children, older adults, or anyone with difficulty swallowing pills.
