Why is zinc important?
Zinc is an essential mineral that is required for hundreds of bodily processes. It is required for DNA replication1,3, immune function2,3, creating proteins3, healing injuries4, and cell division3. Zinc also supports normal growth and development during pregnancy, childhood, and adolescence. 5,7 It is even important for a proper sense of taste and smell!8
How much Zinc do I need?
Because your body cannot store zinc, it is important to get enough zinc from your diet. The amount that is right for you will depend on your gender and age. The Institute of Medicine of the National Academies (formerly National Academy of Sciences) recommends a daily intake of 8mg of zinc for adult females and 11mg for adult males and females who are pregnant and/or breastfeeding.2
What are Plant-Based Sources of Zinc?
While zinc can be obtained from animal products, more people are turning to plant-based sources of zinc to maintain a healthful, anti-inflammatory diet that lowers their carbon footprint. Mix and match these 10 vegan sources of zinc to ensure you’re getting enough in your daily diet.

Am I Getting Enough Zinc?
Adequate amounts of zinc can be obtained from dietary sources, but phytates in whole-grain breads, cereals, legumes, and other foods, bind with zinc and reduce the amount your body can absorb.1,11,12 So if you eat a vegetarian, vegan, or primarily plant-based diet, you may include up to 50% more than the recommended amount of zinc in your diet.
You may also not be getting enough zinc if you are a person with a digestive disorder, like ulcerative colitis or Crohn’s disease. Older infants who are breastfed may also be at risk of zinc deficiency because breast milk does not have enough zinc for infants over 6 months of age; alcoholics; and people with sickle-cell disease.
