The seven that actually go missing.

Not everything — a varied plant-based diet handles most of it without thinking. These are the seven worth paying attention to, how much you need a day, and which plant foods carry them.

Adult reference intakes for general wellness, not medical or dietary advice. Per-serve amounts are estimates.

Vitamin B12

4 µg a day

B12 keeps your nerves and blood cells happy — and plants simply don't make it. Fortified foods are your friends.

Where it comes from, per serve

  • nutritional yeast ≈5 µg per tbsp
  • fortified oat milk ≈1.2 µg per glass
  • yeast extract ≈1.9 µg per serve
  • fortified cereal ≈2.1 µg per bowl

Iron

18 mg a day

Plant iron absorbs better with vitamin C. Squeeze lemon on those greens.

Where it comes from, per serve

  • cooked lentils ≈3.3 mg per cup
  • chickpeas ≈2.9 mg per cup
  • cooked spinach ≈3.2 mg per cup
  • tahini ≈1.3 mg per tbsp

Pumpkin seeds, tahini and lentils are quietly doing the work here.

Where it comes from, per serve

  • tahini ≈1.4 mg per tbsp
  • chickpeas ≈2.5 mg per cup
  • rolled oats ≈1.5 mg per bowl
  • edamame ≈2.1 mg per cup

Calcium

1,000 mg a day

Fortified plant milks are carrying this one. Nice.

Where it comes from, per serve

  • fortified oat milk ≈300 mg per glass
  • calcium-set tofu ≈350 mg per block
  • tahini ≈64 mg per tbsp
  • cooked kale + greens ≈180 mg per cup

Iodine

150 µg a day

Sea vegetables and iodised salt keep your thyroid ticking.

Where it comes from, per serve

  • iodised salt ≈45 µg per ¼ tsp
  • nori sheets ≈35 µg per sheet
  • fortified plant milk ≈45 µg per glass

Omega-3

1.6 g a day

Flax, chia and walnuts — your daily spoonful is paying off.

Where it comes from, per serve

  • chia seeds ≈5 g per tbsp
  • ground flax ≈2.4 g per tbsp
  • edamame ≈0.3 g per cup
  • tofu ≈0.6 g per block

Vitamin D

15 µg a day

Sunshine plus fortified foods. Keep it up through winter.

Where it comes from, per serve

  • fortified plant milk ≈2.4 µg per glass
  • fortified spread ≈1.5 µg per serve
  • fortified cereal ≈2.1 µg per bowl

Only 2 recipes in the collection are a strong source, so there is no separate list for it — Garlic mushrooms on toast, B12 breakfast oats. This is the one most people end up supplementing in winter.

Questions people ask

Which nutrients does a vegan diet run short on?

The seven this page covers: vitamin B12, iron, zinc, calcium, iodine, omega-3 and vitamin D. Not everything — protein and most vitamins are straightforward on a varied plant-based diet. These are the ones worth paying attention to.

Which one matters most?

B12. Plants do not make it at all, so it has to come from fortified foods or a supplement. Every other nutrient here can be covered by food alone with some care.

Are these figures medical advice?

No. They are adult reference intakes for general wellness, and the per-serve amounts are estimates. If a nutrient matters to you clinically, that is a conversation with a doctor or a dietitian, not a website.
