According to the National Institutes of Health, the Tolerable Upper Intake Level (UL) for zinc is 40 mg for most adults. While a daily intake of 20 mg of zinc is within this upper limit for most healthy adults, it is higher than the average Recommended Dietary Allowance (RDA). Individual needs depend on factors like diet, gender, and health status, and it's essential to understand the distinction between appropriate intake and potential overconsumption.
