Douglas Laboratories Vitamin D (5,000 I.U.) | Vitamin D3 Supplement to Support Immune Health, Calcium Levels, and Bones* | 100 Tablets

Many Canadians don't get enough vitamin D from sunlight, especially during the long winter months. Douglas Laboratories Vitamin D offers a convenient 5,000 IU dose of vitamin D3 to help support your body's immune response and maintain strong bones.*

Understanding Vitamin D3 and D2

Vitamin D exists in two forms: D2 (ergocalciferol) from plant sources and D3 (cholecalciferol) from animal sources like lanolin. Research indicates that D3 is more effective at raising and maintaining blood levels of vitamin D. Douglas Laboratories uses D3 for optimal bioavailability, ensuring your body receives the form it uses most efficiently.

Key Benefits of Vitamin D Supplementation

• Supports immune health – Vitamin D helps modulate immune cell function, contributing to a healthy defense system.*
• Promotes calcium absorption – It aids in the absorption of calcium and phosphorus, which are vital for bone mineralization.*
• Maintains normal muscle function – Adequate vitamin D levels support muscle strength and coordination.*
• Contributes to normal cell growth – Vitamin D plays a role in cell division and differentiation.*

These benefits are backed by decades of nutritional science, making vitamin D a cornerstone of daily wellness.

Who May Benefit from Vitamin D Supplementation?

Certain groups are at higher risk for low vitamin D levels, including individuals with limited sun exposure, those living in northern latitudes (a reality for many Canadians), older adults, people with darker skin, and anyone following a vegan diet (though D3 from lanolin is not vegan). If you spend most of your time indoors or wear sunscreen regularly, a vitamin D supplement like this can help fill the gap.

Recommended Dosage of Vitamin D

One tablet daily provides 5,000 IU (125 mcg) of vitamin D3. This strength is often used for maintaining healthy levels or correcting deficiency under professional guidance. As with any supplement, it's wise to consult your healthcare provider to determine the right dosage for your individual needs, especially if you take other medications.
