Plant-based diets are rich in fiber, antioxidants, and many vitamins, but they naturally lack or have lower amounts of:
- Vitamin B12 (almost exclusively found in animal products)
- Vitamin D (limited in plant foods unless fortified)
- Iron (plant-based iron is less easily absorbed)
- Omega-3 fatty acids (especially DHA and EPA)
- Calcium (if dairy is completely avoided)
- Zinc and Iodine (can be lower in vegan diets)
- Vitamin B12
This is the most important supplement for almost all vegans. Since B12 is not reliably found in plant foods, supplementation is strongly recommended. - Vitamin D
Many vegans have low levels, especially during winter or with limited sun exposure. Vegan-friendly Vitamin D3 from lichen or D2 are good options. - Iron
Plant-based iron (non-heme) is harder for the body to absorb. Taking it with Vitamin C can significantly improve uptake. - Omega-3 Fatty Acids (Algal Oil)
Algal oil is the best vegan source of DHA and EPA — the active forms that support brain and heart health. - Calcium
If you avoid fortified plant milks and leafy greens, a calcium supplement may be helpful. It works best when combined with Vitamin D and Magnesium. - Zinc
Plant compounds (phytates) can reduce zinc absorption. Vegans may need slightly higher intake than non-vegans.
- Vitamin B12: 250–500 mcg daily or 2,000–2,500 mcg weekly
- Vitamin D: 1,000–2,000 IU daily (higher if deficient)
- Iron: 18 mg daily for women of childbearing age; 8 mg for men (get blood tested)
- Omega-3 (DHA + EPA): 250–500 mg combined daily from algal oil
- Calcium: 1,000–1,200 mg daily from food + supplements
- Zinc: 15–30 mg daily (take away from high-fiber meals)
- Look for clear “Vegan” or “Plant-Based” certification on the label.
- Choose products with third-party testing (USP, NSF, or ConsumerLab).
- Avoid unnecessary fillers, artificial colors, or high sugar content in gummies.
- Prefer reputable brands with transparent sourcing.
