Complete Vitamin and Mineral RDA Chart: By Age, Gender, and Life Stage
Full RDA charts for every essential vitamin and mineral, broken down by age, gender, and life stage. Includes fat-soluble vitamins, water-soluble vitamins, major minerals, and trace minerals with upper limits, top food sources, and common deficiency data.
Knowing exactly how much of each vitamin and mineral your body needs is the foundation of good nutrition. Yet most people have never seen a single, comprehensive reference that covers every essential micronutrient across every life stage. This article is that reference. Below you will find complete Recommended Dietary Allowance tables for all 27 essential vitamins and minerals, organized by age group, gender, pregnancy, lactation, and elderly status, with upper limits and top food sources included for each nutrient.
Every value in this article is sourced from the National Institutes of Health (NIH) Office of Dietary Supplements, the USDA Dietary Reference Intakes, and the National Academies of Sciences, Engineering, and Medicine. Where RDAs have not been established, Adequate Intake (AI) values are provided and clearly marked.
What Are RDAs and Who Sets Them
The Recommended Dietary Allowance (RDA) is the average daily intake level sufficient to meet the nutrient requirements of 97 to 98 percent of healthy individuals in a particular life stage and gender group. RDAs are established by the Food and Nutrition Board (FNB) at the National Academies of Sciences, Engineering, and Medicine in the United States, and they form the basis of dietary guidance issued by the NIH and USDA.
Internationally, the World Health Organization (WHO) publishes its own set of recommended nutrient intakes (RNIs) that serve a similar purpose. While WHO values occasionally differ from U.S. RDAs due to population-level dietary pattern differences, the core methodology is the same: identify the intake level that prevents deficiency and supports optimal function in the vast majority of the population.
RDAs are updated periodically as new research emerges. The most recent comprehensive update to the Dietary Reference Intakes for calcium and vitamin D was published in 2011, while sodium and potassium values were updated in 2019. The values in this article reflect the most current published DRIs as of early 2026.
RDA vs. AI vs. UL: Understanding the Three Key Values
Before reading the tables below, it is important to understand three distinct reference values that appear throughout this article.
Recommended Dietary Allowance (RDA)
The RDA is the daily intake level that meets the needs of 97 to 98 percent of healthy individuals. When sufficient scientific evidence exists to calculate this value with confidence, an RDA is set. This is the primary target for daily intake.
Adequate Intake (AI)
When evidence is insufficient to establish an RDA, an Adequate Intake value is set instead. The AI is based on observed or experimentally determined estimates of nutrient intake by groups of healthy people. AI values are marked with an asterisk (*) in the tables below. While an AI is not as statistically rigorous as an RDA, it is considered a reliable target for individual intake.
Tolerable Upper Intake Level (UL)
The UL is the maximum daily intake unlikely to cause adverse health effects in almost all individuals. Exceeding the UL does not necessarily mean harm will occur on a given day, but chronic intake above this level increases the risk of toxicity. Not all nutrients have established ULs, particularly those where toxicity evidence is limited.
Fat-Soluble Vitamins: RDA Chart (Vitamins A, D, E, K)
Fat-soluble vitamins are stored in the body's fatty tissue and liver. Because they accumulate over time, both deficiency and toxicity are clinically relevant. The following table provides complete RDA or AI values for all four fat-soluble vitamins.

Common Nutrient Deficiencies by Demographic Group
Even in developed countries with abundant food supply, micronutrient deficiencies remain widespread. The following table summarizes the most common shortfalls by population group based on national dietary survey data (NHANES) and global WHO surveillance.
| Demographic Group | Most Common Deficiencies | Contributing Factors |
|---|---|---|
| Infants and toddlers | Iron, vitamin D, zinc | Rapid growth demands, limited diet variety, low breast-milk vitamin D |
| Children 4–8 years | Calcium, fiber, potassium, vitamin D | Picky eating, high processed food intake, low vegetable consumption |
| Teen females | Iron, calcium, folate, vitamin D | Menstruation onset, restrictive dieting, dairy avoidance |
| Teen males | Calcium, vitamin D, potassium, magnesium | Rapid growth, high calorie but low nutrient-density food choices |
| Adult women (19–50) | Iron, calcium, vitamin D, folate, magnesium | Menstrual losses, inadequate dairy and leafy green intake |
| Adult men (19–50) | Vitamin D, magnesium, potassium | Low fruit and vegetable intake despite adequate calorie consumption |
| Pregnant women | Iron, folate, iodine, vitamin D, calcium, choline | Dramatically increased requirements across multiple nutrients |
| Older adults (65+) | Vitamin B12, vitamin D, calcium, magnesium, potassium | Reduced absorption capacity, lower calorie intake, medication interactions |
| Vegans and vegetarians | Vitamin B12, iron, zinc, calcium, vitamin D, omega-3 (EPA/DHA), iodine | Elimination of animal-source foods that are primary sources of several nutrients |
| Athletes and highly active individuals | Iron, calcium, vitamin D, magnesium, B vitamins | Increased losses through sweat, higher metabolic demand, potential calorie restriction |
Key Statistics on Global Deficiency Prevalence
- Vitamin D: An estimated 1 billion people worldwide have vitamin D deficiency or insufficiency (serum 25(OH)D below 20 ng/mL). In the United States, approximately 42 percent of adults are vitamin D deficient based on NHANES data.
- Iron: Iron deficiency is the most common nutritional deficiency in the world, affecting over 1.2 billion people according to WHO data. In the U.S., approximately 10 percent of women of childbearing age are iron deficient.
- Magnesium: Surveys consistently show that roughly 50 percent of the U.S. population consumes less than the Estimated Average Requirement (EAR) for magnesium.
- Vitamin B12: Deficiency prevalence increases sharply with age, affecting an estimated 6 percent of adults under 60 and up to 20 percent of those over 60 in the United States and United Kingdom.
- Iodine: While iodized salt programs have dramatically reduced deficiency in many countries, approximately 2 billion people globally remain at risk of iodine deficiency, particularly in South Asia, Southeast Asia, and parts of Africa and Europe.
- Calcium: Over 40 percent of the U.S. population does not meet the EAR for calcium from food alone, with teenage girls and elderly women at the highest risk.
How to Track Your Micronutrient Intake
Knowing the RDA values is only useful if you can measure your actual intake against them. Most people vastly overestimate their micronutrient adequacy because they focus exclusively on calories and macronutrients while ignoring vitamins and minerals entirely.
Effective micronutrient tracking requires a tool with a sufficiently detailed nutrient database. Many popular calorie-counting apps track only calories, protein, carbs, fat, and perhaps a handful of vitamins. This leaves dozens of essential nutrients invisible in your daily totals.
Nutrola tracks over 100 nutrients per food entry, including every vitamin and mineral listed in the tables above. Its verified food database is built from laboratory-analyzed sources, not user-submitted entries. When you log a meal using photo recognition or voice logging, you see your complete micronutrient profile for the day, making it straightforward to identify shortfalls before they become clinical deficiencies. The core tracking features, including full micronutrient breakdowns, are available for free.
For anyone using these RDA charts as a reference, the practical next step is to track your actual intake for at least seven consecutive days to establish a baseline. Single-day snapshots are misleading because micronutrient intake varies significantly from day to day. A seven-day average provides a much more reliable picture of your habitual nutrient status.
Special Considerations by Life Stage
Pregnancy and Lactation
Pregnancy increases requirements for nearly every micronutrient, but the most critical increases are for folate (from 400 to 600 mcg DFE), iron (from 18 to 27 mg), iodine (from 150 to 220 mcg), and calcium (maintained at 1,000 mg but with increased absorption efficiency). Prenatal supplements are widely recommended because meeting these elevated targets through food alone is extremely difficult, particularly for iron and folate.
During lactation, calorie needs increase by approximately 450 to 500 calories per day, and several nutrient requirements are even higher than during pregnancy. Vitamin A needs jump to 1,200 to 1,300 mcg RAE, vitamin C increases to 115 to 120 mg, and iodine requirements rise to 290 mcg, the highest of any life stage.
Elderly Adults (65+)
Aging affects micronutrient status through multiple mechanisms: reduced stomach acid production decreases B12 and iron absorption, lower sunlight exposure and reduced skin synthesis capacity decrease vitamin D status, and declining calorie intake often means less total nutrient intake across the board.
The vitamin D RDA increases from 600 IU (15 mcg) to 800 IU (20 mcg) after age 70. Calcium requirements increase to 1,200 mg for women over 50 and all adults over 70. The NIH specifically recommends that adults over 50 obtain vitamin B12 from fortified foods or supplements because the crystalline form in these products does not require stomach acid for absorption.
Vegetarians and Vegans
Plant-based diets can meet the vast majority of micronutrient needs, but several nutrients require deliberate planning. Vitamin B12 has no reliable plant food sources and must be obtained from fortified foods or supplements. Iron from plant sources (non-heme iron) is absorbed at roughly 2 to 20 percent efficiency compared to 15 to 35 percent for heme iron from animal foods, which is why the iron RDA for vegetarians is 1.8 times the standard recommendation. Zinc absorption is similarly reduced by the phytates present in whole grains, legumes, and nuts.
FAQ
What is the difference between RDA and Daily Value (DV) on nutrition labels?
The RDA is a set of age- and gender-specific intake recommendations set by the National Academies. The Daily Value (DV), which appears on Nutrition Facts labels in the United States, is a single reference value used for all adults and children over four years old. DVs are derived from RDAs but are simplified into one number for labeling purposes. For example, the DV for calcium is 1,300 mg (based on the highest adult RDA), while the actual RDA for men aged 19 to 50 is 1,000 mg. This means some individuals may see 100 percent DV on a label while actually exceeding their personal RDA.
Can I get all my vitamins and minerals from food alone?
For most healthy adults eating a varied diet that includes fruits, vegetables, whole grains, lean proteins, dairy or fortified alternatives, and healthy fats, it is possible to meet the majority of micronutrient needs from food. However, certain nutrients are exceptionally difficult to obtain in adequate amounts from food alone for specific populations. Vitamin D is hard to achieve without sun exposure or supplementation. Vitamin B12 requires supplementation for strict vegans. Iron during pregnancy almost always requires supplementation. Folate during the periconceptional period is recommended from supplements in addition to food sources.
Are RDA values the same worldwide?
No. While the underlying science is similar, different countries and organizations set slightly different recommended values based on their population's dietary patterns, genetic backgrounds, food fortification policies, and public health priorities. For example, the WHO recommends 5 mcg (200 IU) of vitamin D per day for adults under 50, while the U.S. RDA is 15 mcg (600 IU). Japanese dietary reference intakes for sodium are higher than U.S. values reflecting typical dietary patterns. The tables in this article use U.S. DRI values established by the National Academies.
Is it dangerous to exceed the RDA?
Exceeding the RDA is not inherently dangerous. The RDA is a minimum target, not a maximum. The relevant safety ceiling is the Tolerable Upper Intake Level (UL). Intake between the RDA and UL is generally considered safe and may even be beneficial for some nutrients in some individuals. Intake above the UL, particularly from supplements, can cause adverse effects. For example, chronic vitamin A intake above the UL (3,000 mcg for adults) can cause liver toxicity, and excessive iron supplementation (above 45 mg daily) can cause gastrointestinal distress and, in extreme cases, organ damage. Nutrients without an established UL (like vitamin B12 and vitamin K) have not demonstrated toxicity at high intakes in healthy individuals, though this does not mean unlimited supplementation is advisable.
Do athletes need higher micronutrient intakes than the RDA?
Current RDAs are set for generally healthy individuals and do not account for the increased metabolic demands, sweat losses, and tissue repair needs of athletes. Research suggests that physically active individuals may need more iron (due to exercise-induced hemolysis and increased red blood cell production), magnesium (lost in sweat and consumed in energy metabolism), B vitamins (involved in energy production pathways that are upregulated during exercise), and vitamin D (particularly for indoor athletes with limited sun exposure). However, no separate set of athlete-specific RDAs exists. Most sports nutrition guidelines recommend that athletes meet the standard RDA as a minimum and pay particular attention to iron, vitamin D, calcium, and magnesium status through regular blood work.
How often should I get blood work done to check my micronutrient levels?
For healthy adults with no known deficiencies, an annual comprehensive metabolic panel and complete blood count (CBC) is a reasonable baseline. If you suspect specific deficiencies based on symptoms or dietary patterns, targeted tests are available: serum 25-hydroxyvitamin D for vitamin D status, serum ferritin for iron stores, serum B12 and methylmalonic acid for B12 status, and red blood cell magnesium for magnesium status (more reliable than serum magnesium). Pregnant women, elderly adults, vegans, and individuals with malabsorption conditions (celiac disease, Crohn's disease, gastric bypass history) may benefit from more frequent testing, typically every three to six months for nutrients of concern.
