Supplements for a vegan diet

• Vitamin B12 (essential): 250 mcg daily or 2,500 mcg weekly, or fortified foods
• Vitamin D (D2 or lichen-derived D3): 1,000-2,000 IU daily; ideally test your level
• Algae-based EPA/DHA: 250-500 mg daily
• Iodine: 150 mcg daily if not using iodized salt or seaweed; avoid excess kelp
• Selenium: 50-100 mcg, or 1-2 Brazil nuts daily
• Choline (optional): consider if intake is low
• Iron, zinc, calcium: test first; supplement only if a gap is found
• Creatine (optional): vegans often have low stores

Caveats

• Tiers 1-2 rest on RCTs and large cohorts; Tiers 4-5 are often small trials or lab studies.
• Many associations (coffee, nuts, whole grains) are observational and cannot prove causation.
• Overall dietary pattern matters more than any single food.
• Interactions: grapefruit with statins; vitamin K greens and natto with warfarin; high-sodium ferments with hypertension.
• Vegan does not automatically mean healthy; refined grains, sugary drinks and ultra-processed substitutes erode the benefits.
