INSIGHT

Supplements Make Vegan Diets Healthy

  • Vegan diets require B12 from supplements or fortified foods but being 'unnatural' doesn't make them unhealthy; outcome data show vegans often have better cardiovascular and mortality metrics.
  • Nutrient risks differ by diet: vegans excel in fiber/folate but need attention to B12, D, calcium, iodine.
ADVICE

Essential Supplements For People On Vegan Diets

  • Vegans should ensure B12, vitamin D, calcium (via fortified milks), and iodine are covered, using supplements or fortified foods as insurance.
  • A daily multivitamin containing B12, D and iodine is a convenient, effective option.
INSIGHT

  • Habitual intake and gut adaptations (and choosing calcium-fortified sources) mitigate concerns; higher phytate markers linked to better bone density.
