The available ranges run from 1 to 3 months through 75+ years.<\/li>\n<li>Select <strong>Male<\/strong> or <strong>Female<\/strong> in <strong>Gender<\/strong>. For children younger than 11 years, both selections use the same age-group table.<\/li>\n<li>If you selected <strong>Female<\/strong> and <strong>18 to 59 years<\/strong>, use <strong>Additional<\/strong> to choose <strong>Pregnancy<\/strong>, <strong>Lactation<\/strong>, or <strong>\u2014<\/strong>. This field is not available for other selections.<\/li>\n<li>Read the separate <strong>Vitamins<\/strong> and <strong>Minerals<\/strong> results. Check the unit beside each amount: mcg means micrograms, while mg means milligrams.<\/li>\n<\/ol>\n<h2>What daily vitamin and mineral requirements mean<\/h2>\n<p>Vitamins and minerals support functions such as growth, bone maintenance, blood formation, and normal metabolism. The calculator presents daily reference amounts for its broad age and gender groups, with separate pregnancy and lactation tables for women aged 18 to 59. It is a quick way to see which nutrients are listed and how the table changes between groups.<\/p>\n<p>Each result is an amount <em>per day<\/em>, not a recommended supplement dose or a measurement of your current intake. A value such as 400 mcg of vitamin A refers to the amount shown in this calculator\u2019s table. Where a result is a range, such as 50\u201355 mg, the table provides a range rather than one personalized target. The upper end is <strong>not<\/strong> a safe upper intake limit.<\/p>\n<p>Daily intake comes from the whole diet, including foods, drinks, and any supplements. Meeting an energy goal does not automatically provide enough micronutrients: two meals with similar calories can differ substantially in nutrient content. For a broader view of eating patterns, you can compare this page with the <a href=\"https:\/\/wpcalc.com\/en\/beauty\/calorie-of-food\/\">Calorie of Food calculator<\/a>, <a href=\"https:\/\/wpcalc.com\/en\/beauty\/protein-calculator\/\">Daily Protein Intake calculator<\/a>, and <a href=\"https:\/\/wpcalc.com\/en\/beauty\/water-requirement\/\">Daily Water Intake calculator<\/a>.<\/p>\n<h2>Assumptions and practical limits<\/h2>\n<p><strong>These figures come from the calculator\u2019s built-in table, not a live dietary-guideline database.<\/strong> Nutrient recommendations differ by country, issuing organization, age definition, and the form of a nutrient being measured. Some displayed figures may differ from current guidance where you live. Use the results as general reference information, not as a clinical prescription or a substitute for locally applicable recommendations.<\/p>\n<p>The calculator uses broad categories and does not ask about medical conditions, medications, dietary restrictions, absorption problems, or confirmed deficiencies. It also does not estimate how much of a nutrient you eat. Selecting an age group changes the table; it does not account for differences within that group. At a boundary between two age ranges, use the range intended for the person\u2019s current age and consult age-specific guidance if the distinction matters.<\/p>\n<p><strong>Pay close attention to units.<\/strong> One milligram equals 1,000 micrograms, so 0.15 mg and 150 mcg represent the same quantity. Some nutrients appear in mg for one age group and mcg for another. The table also uses names such as \u201cChrome\u201d and \u201cFluorine\u201d; read them as the calculator\u2019s displayed labels rather than assuming its terminology matches a particular nutrition standard.<\/p>\n<p>For infants and children, do not turn a table value into a supplement dose. Feeding guidance depends on age, diet, and clinical circumstances. During pregnancy, take particular care with vitamin A and iron supplements: nutrient form and dose matter, and excess intake can be harmful. If you are pregnant, lactating, managing a medical condition, or considering supplements, ask a qualified healthcare professional which guidance applies to you.<\/p>\n","protected":false},"excerpt":{"rendered":"<p>View daily vitamin and mineral reference amounts by age and gender.
