Vegan Nutrition: B12, Iron & Protein

Eating vegan can be an expression of care for animals and a joyful way to explore food. It also deserves thoughtful planning. A varied plate matters more than a list of fashionable ingredients: include vegetables and fruit, grains or starchy foods, protein foods and sources of fat.

Vegan does not automatically mean nutritionally complete, and no single recipe can meet every person's needs. This is a general introduction, not a personal nutrition plan.

Vitamin B12 is not naturally supplied by unfortified plant foods. Fortified foods and supplements are therefore important considerations for people eating vegan. Read labels rather than assuming a plant milk, nutritional yeast or fermented food contains B12.

NIH guidance lists an adult recommended daily amount of 2.4 micrograms; that is a dietary reference, not a supplement-dosing instruction. Needs differ during pregnancy and breastfeeding. Ask a qualified clinician or registered dietitian about a reliable plan for your circumstances.

Beans, lentils, chickpeas, tofu, tempeh, nuts and seeds can contribute protein. Build meals around foods you enjoy: lentil soup, tofu with rice and vegetables, or chickpeas folded into a crunchy salad. Individual requirements depend on factors such as age, activity and health.

Pulses, some fortified cereals, nuts and leafy greens can contribute iron. Plant-based iron is absorbed less readily than iron from meat; including a vitamin C source such as peppers, citrus or broccoli at a meal can help with absorption.

B12, iron and protein are not the whole picture. Calcium, vitamin D, iodine and omega-3 fats also merit attention. Pregnancy, childhood, medical conditions and symptoms such as persistent fatigue call for individualized advice rather than guessing at supplements.
