Why might people need zinc?
Most people in the United States get enough zinc from their food, the NIH reports. But people with limited food intake and people in the following groups may find it difficult:
NIH
People with digestive disorders or past gastrointestinal surgery: Disorders, such as ulcerative colitis and Crohn’s disease, decrease the amount of zinc the body absorbs and increase the amount lost through urination.
ulcerative colitis
Crohn’s disease
People with vegetarian or vegan diets: People with these diets may need 50% more zinc than the recommended daily allowance (RDA).
Breastfed infants over 6 months old: Breast milk does not contain enough zinc for an infant older than 6 months. Formulas and pureed meats can provide the required amount.
People with alcohol use disorder: Alcohol reduces the amount of zinc that the body absorbs and increases the amount lost through urination.
alcohol use disorder
Alcohol
People with sickle cell disease: Research suggests that 44% of children with sickle cell disease have low plasma zinc concentrations. Additionally, 60–70% of adults with sickle cell disease have insufficient amounts of zinc in their bodies.
44%
Pregnant or breastfeeding people: Pregnancy can cause a zinc deficiency due to the high zinc requirement of a developing fetus. Also, breast milk contains zinc to nourish the baby, leaving less for the body to use.
zinc deficiency
Older adults: Researchers have found that adults aged 60 years or older who do not always eat enough may have a zinc intake of less than half of the RDA. Also, reduced zinc levels in older adults can stem from difficulty eating certain foods or drug interactions.
