Quick answer
For most Canadians, a plant-based vitamin D3 (cholecalciferol) from organic lichen offers the best balance of efficacy, vegan compatibility, and absorption. Focus on the form, source, and IU per serving to match your needs.
Why form matters: D3 vs D2
Vitamin D comes in two main forms: D2 (ergocalciferol) from yeast or fungi, and D3 (cholecalciferol) from animal or lichen sources. D3 is the same form your skin produces from sunlight and is generally more effective at raising and maintaining blood levels. If you are vegan, look for D3 derived from organic lichen rather than lanolin (sheep wool).
Potency and dosage considerations
Most Canadian adults benefit from 1,000–2,000 IU of vitamin D3 daily, especially during fall and winter. Those with darker skin, limited sun exposure, or certain health conditions may need higher amounts. Always check the IU per drop or capsule, and consider starting with a moderate dose and adjusting based on blood tests.
Vegan and organic considerations
Many vitamin D3 supplements use lanolin, which is not vegan. Plant-based options from organic lichen are available and provide the same D3 form without animal involvement. If you follow a vegan or vegetarian diet, check the label for 'lichen-derived' or 'plant-based' D3.
Your decision rules
- Check the form: Choose vitamin D3 (cholecalciferol) over D2 for better absorption and maintenance of blood levels.
- Verify the source: If you are vegan or prefer plant-based, select a D3 from organic lichen rather than lanolin.
- Match the IU to your needs: Start with 1,000–2,000 IU daily for general maintenance; higher doses may be appropriate for specific deficiencies or medical advice. Consider a blood test after 3 months to fine-tune your dose.
