Vegan Nutrition & Supplements
Nutrition focuses on the supplement and fortified-food questions vegans actually ask: which B12 form to consider, whether a D3 is lichen-derived or lanolin-derived, how algae omega-3 compares to fish oil, and when the iron in a multivitamin deserves caution. Individual nutrient guides cover B12, vitamin D, omega-3, iodine, iron, zinc, selenium, calcium, choline, and creatine, alongside practical topics like supplement forms, storage, third-party testing, and how to compare supplement labels.
Every guide in this category is educational, not medical advice. Supplement decisions depend on your diet, labs, medications, and clinician guidance — these guides are designed to help you ask better questions, not to replace them.
If you are starting from zero, read the Beginner’s Guide to Vegan Supplements first, then use the Vegan Supplements collection to compare source-checked products in each nutrient group.
