Key Nutrients Often Lacking in Vegan Diets


A well-planned vegan diet is healthy, but some nutrients are harder to get from plants.


According to scientific consensus and PubMed reviews, the nutrients most likely to be insufficient in a vegan diet are:

  1. Vitamin B12
  2. Vitamin D (especially D3)
  3. Omega-3 fatty acids (especially EPA & DHA)
  4. Iron (plant iron is less bioavailable)
  5. Zinc
  6. Calcium
  7. Iodine
  8. Selenium
  9. Vitamin K2
  10. Sometimes protein (especially for athletes/older adults)
  11. Occasionally, certain amino acids (lysine, methionine) and vitamin A (as preformed retinol)

Zinc Zinc citrate or gluconate 10–15 mg Lower absorption from plants

Calcium Algae calcium or citrate 300–500 mg Plant sources not always enough Iodine Kelp powder or potassium iodide 75–150 mcg Varies by soil, low in plants
