Micronutrient requirements

Position of the American Dietetic Association: Glycogen replenishment benefits and Microhutrient supplements. Dieting for Reauirements loss, avoiding entire food groups, or eating the same Micdonutrient with little variety limits your micronutrient intake and leads to more significant vitamin and mineral insufficiencies. Compared to intake from food alone, use of MVMs was associated with a lower prevalence of inadequacy for several 'shortfall' i. Czeizel, Dudás, Atlantic diet may help prevent metabolic syndrome.

Micronutrient requirements -

Sources and recommended intakes of fat-soluble vitamins are 17 , 18 , 19 , 20 :. Macrominerals are needed in larger amounts than trace minerals in order to perform their specific roles in your body. Sources and recommended intakes of the macrominerals are 21 , 22 , 23 , 24, 25 , 26 , 27 :.

Trace minerals are needed in smaller amounts than macrominerals but still enable important functions in your body. Sources and recommended intakes of trace minerals are 28 , 29 , 30 , 31 , 32 , 33 , 34 :.

Micronutrients can be divided into four groups — water-soluble vitamins, fat-soluble vitamins, macrominerals and trace minerals. The functions, food sources and recommended intakes of each vitamin and mineral vary. Consuming an adequate amount of the different vitamins and minerals is key to optimal health and may even help fight disease.

This is because micronutrients are part of nearly every process in your body. Moreover, certain vitamins and minerals can act as antioxidants. For example, research has linked an adequate dietary intake of vitamins A and C with a lower risk of some types of cancer 4 , 5.

Research has linked low blood levels of selenium to a higher risk of heart disease. Additionally, a review of 22 studies noticed that adequate calcium intake decreases the risk of death from heart disease and all other causes These studies suggest that consuming enough of all micronutrients — especially those with antioxidant properties — provides ample health benefits.

Micronutrients are part of nearly every process in your body. Some even act as antioxidants. Due to their important role in health, they may protect against diseases.

Most healthy adults can get an adequate amount of micronutrients from a balanced diet, but there are some common nutrient deficiencies that affect certain populations. The signs, symptoms and long-term effects of these deficiencies depend on each nutrient but can be detrimental to the proper functioning of your body and optimal health.

They are most likely to occur with large doses of the fat-soluble vitamins A, D, E and K since these nutrients can be stored in your liver and fatty tissues. They cannot be excreted from your body like water-soluble vitamins. A micronutrient toxicity usually develops from supplementing with excess amounts — rarely from food sources.

Signs and symptoms of toxicity vary depending on the nutrient. One study examined over 18, people with a high risk of lung cancer due to past smoking or asbestos exposure. The intervention group received two types of vitamin A — 30 mg of beta-carotene and 25, IU of retinyl palmitate a day The safest and most effective way to get adequate vitamin and mineral intake appears to be from food sources 51 , However, people at risk of specific nutrient deficiencies may benefit from taking supplements under the supervision of a doctor.

Since your body requires micronutrients in specific amounts, deficiencies and surpluses of any one nutrient may lead to negative issues. Vitamins are needed for energy production, immune function , blood clotting and other functions while minerals benefit growth, bone health, fluid balance and other processes.

To get an adequate amount of micronutrients, aim for a balanced diet containing a variety of foods. Our experts continually monitor the health and wellness space, and we update our articles when new information becomes available.

Symptoms may include stubby roots, some chlorosis of new leaves and plant wilting. Copper is not readily transferred from old to young leaves, so older leaves remain darker and relatively healthy and the deficiency symptoms develop on younger leaves. The visual symptoms of a copper deficiency in wheat include: yellowing of younger leaves, limpness, wilting, pigtailing whip tailing or curling of the upper leaves and kinking of the leaf tips.

Other signs include: excessive tillering, aborted heads, delayed maturity and poor grain filling resulting in a high straw to grain ratio. On copper deficient soils these symptoms tend to occur in irregular patches. Copper deficiency is often associated with the disease stem or head melanosis and an increased incidence of ergot.

For barley, the symptoms of a copper deficiency include yellowing, pigtailing, awn kinking, excessive tillering and weak straw. Oats will also show pigtailing.

Chlorosis of the younger leaves characterizes an iron deficiency. The tissue between the veins gradually turns yellow, while the veins tend to stay green. The tips and margins of some leaves may turn brown and become dry and brittle. In legumes, deficiency symptoms include pale green young leaves and a pale yellow mottling develops in interveinal areas, while the veins remain green.

Oats are an excellent indicator crop. Manganese is partly mobile in oats. White to grey flecks or specks first appear and become more severe on mature leaves about halfway up the shoot. If a deficiency persists, symptoms spread to old leaves, then to the youngest leaves.

In wheat and barley, manganese is not readily transferred from old to young leaves. Affected young leaves frequently turn pale green and have a limp or wilted appearance.

A mild interveinal chlorosis develops in the mid-section of the leaf and spreads rapidly becoming pale yellow-green. Small white to grey spots, specks or strips appear a short distance from the end of the leaf tip on young leaves.

Molybdenum deficiency symptoms are similar to those of nitrogen. Since molybdenum deficiencies are very uncommon symptoms are rarely seen.

Zinc is partly mobile in wheat and barley. In these crops, pale yellow chlorotic areas appear on middle leaves, halfway up the stem.

Chlorotic symptoms first develop in the lower half or mid-section of the leaf followed by grey or dark brown necrosis of the leaf. Generally, stems are very short and often fan-shaped with leaves crowded together at the top.

Zinc-deficient beans are stunted and older leaves are smaller and narrower. The older leaves may have light blotches between the veins. Younger leaves will have a more normal healthy green colour but may be smaller. In flax, a zinc deficiency can cause grayish-brown spots in the younger leaves with shortened internode spaces and stunted appearance.

In corn, symptoms occur within a few weeks of emergence as light-yellow bands on the youngest leaves. Old leaves remain dark green and appear healthy.

In a prolonged case of deficiency, the middle leaves develop pale yellow interveinal chlorosis near the tips. A zinc deficiency prevents the elongation of internodes and leaves, which results in short stems with the leaves crowded together at the top in a fan-shaped appearance.

Soil tests aid in determining whether a particular nutrient is responsible for poor production. They also provide the basis for deciding the type and amount of fertilizer needed to correct a nutrient shortage. A soil sample used for laboratory analysis must consist of a composite of a number of samples taken from the field.

The DTPA diethylenetriamine pentaacetic acid method is used to extract the metal micronutrients. Hot water is used to extract boron.

Either water or sodium nitrate is used to extract chlorine. Analytical results are usually given in parts per million ppm. No soil test has proven particularly useful in predicting the availability of molybdenum.

The micronutrients that are normally tested for are boron, copper, iron, manganese, and zinc. Surface soil samples 0 to 15 cm should be taken from both the affected area and an adjacent area of good crop growth for comparison.

The general range levels used for determining when to add micronutrients for improving crop production are shown in table 2. When a soil sample tests low in a micronutrient, a potential micronutrient deficiency may occur.

Some soils with low micronutrient levels at the surface 0 to 15 cm do not respond to fertilization because they have higher levels of the nutrient in the subsoil. Table notes: a This level is used by some labs as a critical level for recommending Cl for disease suppression in cereals b Brown and Dark Brown soil areas c Black and Grey Wooded soil areas d Organic soils.

Plant tissue tests can aid in determining if a particular nutrient is responsible for poor crop growth. When a deficiency is detected by tissue sampling, a reduction in yield due to restricted crop growth has already occurred. As with soil analysis, tests involving plant tissue must be calibrated with field fertilizer trials.

Calibration in this case is far more complex than for soil tests. The reason is that measured nutrient concentration, which is the basis of the tests, varies considerably with the stage of plant development and the portion of the plant sampled.

Special care is required in taking plant tissue samples. Representative plant tissue samples can be taken early in the growing season to assist in the interpretation of soil tests. For small grain crops all of the above-ground portions should be sampled.

For alfalfa or other forage legumes, the top 6 inches 15 cm should consist of the first fully mature leaves. Normally, 25 plants should be sampled to provide a good representation of the field and ensure a sufficient quantity of the sample for complete analysis.

The fresh samples should be air-dried to remove excess moisture before they are shipped to a lab. Plant tissue samples should be taken from both an affected area and an adjacent area of good crops growth for comparison. Taking soil and plant tissue samples at the same time will aid in determining if a micronutrient is deficient.

A range of levels of micronutrients has been established for a number of crops at various stages of growth. Even after observing micronutrient deficiency symptoms and conducting soil and plant tissue analyses it can still be difficult to predict if a profitable yield response will occur.

Therefore, the micronutrient suspected of being deficient should be applied to a small affected area of the field. The test strip areas must be carefully marked out for comparison to areas where micronutrients were not used.

Visual observations and yields from the treated and untreated areas should be taken to determine if a measurable response occurred. For the most current information on micronutrient recommendations, sources and methods of application for specific crops on problem soils, see: Alberta Farm Fertilizer Information and Recommendation Manager AFFIRM.

Table 3 lists some common inorganic micronutrient fertilizers. The inorganic forms are the most economical. The organic sources are synthetic chelates which are considered to be more available in some soil types. Application of borate or borax can be either broadcast and incorporated, or banded.

Boron containing fertilizers should not come into contact with the seed at planting time. For permanent crops such as alfalfa, boron should be used as a topdressing. Soil application rates should not exceed 1. Foliar applications should not exceed 0.

For all types of applications, extreme care must be taken to apply the correct amount and to apply it uniformly to avoid toxicity problems. Soil application rates should be effective for up to 10 years.

Chelated forms of copper are also very effective in the year of application but little is known about the residual effects in Alberta soils. Foliar application on mineral and organic soils is not as consistent but can be used after deficiency symptoms appear. Foliar applications are required annually and are most effective at the late tillering stage.

If the deficiency is severe, 2 applications mid-tillering and boot stage are necessary. Foliar rates of between 0. Only limited information is available on manganese fertilization in Alberta.

As a rule, broadcast applications are seldom effective. For cereals, a seed-placed treatment of manganese sulphate should be most effective. Foliar application can also be used if deficiency symptoms develop during the growing season.

When zinc deficiencies are suspected early in the growing season, a foliar application of 0. Severely, deficient beans may require 2 applications. The need for micronutrients in crop production has long been recognized in Alberta. Zinc deficiencies in irrigated beans in southern Alberta were detected in the early s.

Research by Alberta Agriculture and Agriculture Canada has clearly shown the need for copper fertilizer, particularly for wheat grown on organic soils and on some Black and Grey-Black soils in central Alberta.

One million acres may be copper deficient in central Alberta. Continued research and testing is required to identify when various crops will give economic yield increases to additions of micronutrient fertilizers.

It is important to keep the need for micronutrient fertilizers in perspective. Over-promotion of micronutrients has occurred on occasion. Some farmers have applied micronutrients in the hope of increasing crop yields even though there is little evidence to suggest a deficiency exists.

Farmers who are concerned about micronutrient deficiencies are encouraged to investigate the need thoroughly and apply the nutrients in test strips if necessary.

No effect of MVM supplementation on vascular-related mortality 10 trials or cancer -related mortality 9 trials was found in this meta-analysis Another meta-analysis that included prospective cohort studies , in addition to randomized controlled trials, reported similar results Thus, MVMs are generally considered as safe in healthy individuals because they contain amounts of micronutrients that approximate or equal the DVs.

For adults, the DV for most micronutrients is considerably lower than the tolerable upper intake level UL — "the highest level of daily intake of a specific nutrient likely to pose no risk of adverse health effects in almost all individuals of a specified age" Intake of any micronutrient from food, fortified food, and supplements should not chronically exceed its UL Some analyses of NHANES data have looked at the proportion of the US population with nutrient intakes in excess of the UL when accounting for intake from all sources — food, including fortified and enriched food, and dietary supplements.

Micronutrient intakes above the UL are more common among children. As stated above, some have expressed concern that the UL for children is set too low for certain nutrients i.

More generally, some have pointed out that the dose-response curves needed for risk assessment of individuals in a specific gender and life stage group have not been done for most micronutrients, and for these nutrients, estimating an intake level that is associated with risk of adverse effects is not possible Thus, for some nutrients, one cannot label intakes greater than the UL as "excessive" The nutrient that is overconsumed by the US population, sodium, is not included in MVMs — sodium intake comes from dietary sources, mainly processed food 1.

Thus, it is important to look for an MVM that contains no more than recommended amounts of vitamins and minerals i. Although dosages of micronutrients included in most MVMs are generally safe, some supplements may provide excessive vitamin A or iron.

For this reason, the Linus Pauling Institute LPI recommends that adults take a MVM supplement that provides no more than 2, IU μg of preformed vitamin A usually labeled vitamin A acetate or vitamin A palmitate and no more than 2, IU of additional vitamin A as β-carotene.

Additionally, because excess preformed vitamin A retinol during pregnancy is known to cause birth defects and because a number of foods in the US are fortified with retinol, LPI recommends that pregnant women avoid a MVM or prenatal supplements that contain more than 5, IU 1, μg of vitamin A in the form of retinol.

Moreover, children should not be given a MVM supplement that contains more retinol than the RDA for their age group see the Table 1 in the article on vitamin A. Men and postmenopausal women are not at risk for iron deficiency, and excess iron from the diet and supplements can have adverse effects.

Therefore, LPI recommends that men and postmenopausal women take a MVM supplement without iron. A number of MVMs formulated specifically for men or for those over 50 years of age do not contain iron. Even though MVM supplements are safe for most people, individuals should discuss the use of all nutritional supplements with a competent healthcare professional.

People taking pharmaceutical drugs to treat certain medical conditions need to be aware of any potential drug-nutrient interactions; some potential interactions are listed in the article on Subpopulations at Risk for Micronutrient Inadequacy or Deficiency: see the section on Those Taking Drugs Known to Interact with Nutrients.

Another safety issue concerns the quality of commercially available MVM supplements. In , the US Food and Drug Administration established standards of current good manufacturing practices CGMPs , which ensure dietary supplements meet quality standards with respect to identity, purity, strength, and composition All US and foreign companies were required to comply with the CGMPs by June In addition to these government regulations, at least three independent organizations evaluate the quality of dietary supplements on a fee basis: NSF International , US Pharmacopeia , and ConsumerLab.

Supplement labels of approved products can bear the certification mark, verification mark, or seal of approval of these organizations. However, many products that are in full compliance do not carry such certification marks on their labels, and absence of a seal does not mean lack of adherence to CGMP or other regulations.

Nutrition education campaigns have yet to convince people to make better food choices: The reality is that most Americans do not follow a healthy eating pattern and instead eat an energy-rich, nutrient-poor diet 1.

MVMs are a simple, inexpensive, and safe way to help fill nutritional gaps and improve micronutrient status. While the specific consequences of chronic micronutrient inadequacies are difficult to document, it is prudent and affordable to ensure adequacy for health by taking a daily MVM supplement.

Other micronutrient supplements may be needed if intake recommendations are not being met by a combination of dietary sources and the MVM. As mentioned above, some micronutrients e. In addition to a daily MVM, the Linus Pauling Institute recommends a few additional micronutrient supplements:.

The Linus Pauling Institute recommends that generally healthy adults take 2, IU 50 μg of supplemental vitamin D daily. Most multivitamins contain IU 10 μg or IU 15 μg of vitamin D, and single-ingredient supplements are available for additional supplementation.

Sun exposure, diet, skin color, and body mass index BMI have variable, substantial impact on body vitamin D levels.

The American Academy of Pediatrics currently suggests that all infants, children, and adolescents receive IU of supplemental vitamin D daily Consistent with the recommendations of the Endocrine Society 61 , the Linus Pauling Institute recommends daily intakes of to 1, IU 10 to 25 µg of vitamin D in infants and to 1, IU 15 to 25 µg of vitamin D in children and adolescents.

Given the average vitamin D content of breast milk, infant formula, and the diets of children and adolescents, supplementation may be necessary to meet these recommendations.

More on vitamin D. Because of the high benefit-to-risk ratio of vitamin C supplementation, and to ensure tissue and body saturation of vitamin C in almost all healthy people, the Linus Pauling Institute recommends a vitamin C intake of at least mg daily for adult men and women.

Consuming at least five servings 2½ cups of fruit and vegetables daily provides about mg of vitamin C. More on vitamin C. A varied diet should provide enough vitamin B 12 to prevent deficiency in most individuals 50 years of age and younger.

Strict vegetarians and women planning to become pregnant should take a daily multivitamin supplement or eat fortified cereal, which would ensure a daily intake of 6 to 30 µg of vitamin B 12 in a form that is easily absorbed. Supplemental vitamin B 12 is also recommended for patients taking medications that interfere with its absorption see Drug interactions in the separate article on vitamin B More on vitamin B Consumption of an energy-rich, nutrient-poor diet — the current dietary pattern in the United States — results in suboptimal health and increases risk of chronic disease.

Despite decades of public health messages to eat a balanced diet, overall adherence to the Dietary Guidelines for Americans 1 is low.

As a result, micronutrient inadequacies, especially vitamins A, C, D, and E; calcium; and magnesium, are quite prevalent in the population among various age groups and ethnicities 33 , Certain subgroups of the population are at a heightened risk of micronutrient deficiencies due to several factors, including life stage, disease status, pharmaceutical use, and various lifestyle choices.

While debate about the optimal diet for health continues 64 , there is ample evidence to support the benefits of following a healthy eating pattern like those discussed in the Dietary Guidelines for Americans — plant-based diets abundant in fruit, vegetables , legumes , whole grains , nuts , and seeds and limited in processed food.

Adhering to such an eating pattern is important to obtain the nutrients needed for optimal health and to help prevent chronic disease throughout the lifespan. Depending on diet and life stage, additional single-nutrient supplements like vitamins B 12 , C, and D may be needed to reach micronutrient intake recommendations.

Many studies have shown that use of dietary supplements results in improved micronutrient intake and thus decreased prevalence of micronutrient inadequacy in the population.

However, supplements should not replace a healthful eating pattern; on the contrary, by definition "supplements" should be used to complement healthy eating to ensure nutrient adequacy for optimal health. Written in January by: Victoria J.
