The only reported micronutrient deficiencies in Continuous glucose control Ginseng tea benefits have been Micronutrirnts B, Cu, Mn and Zn.
These deficiencies can cause plant abnormalities, reduced growth and sometimes yield losses. Over the past 40 years, there have been ongoing efforts to evaluate the effect of micronutrient fertilization on field crop yields.
Here we have compiled all available studies conducted by Ohio State University which examined the effect of micronutrient fertilization on field crop yields in Ohio. We found a total of trials that tested a micronutrient fertilized treatment or set of treatments relative to an unfertilized control treatment.
Five micronutrients were evaluated independently B, Cu, Mn, Mo, or Zn in these trials, while some of these trials evaluated a combination of micronutrients.
There was a total of 17 alfalfa trials, 33 corn trials and soybean trials Table 3. These field trials were conducted in a total of 17 Ohio counties Figure below. This historical summary of micronutrient trials in Ohio demonstrates that yield responses to micronutrient fertilization are not common.
In fact, the only responses observed with micronutrient fertilization occurred when Mn was applied to soybean 9 out of trials and when boron was applied to corn 1 out of 9 trials. While infrequent, it is important to keep in mind that probability of a yield response to micronutrients is much greater in scenarios where deficiencies are known, or suspected to be more prevalent, for example, in sandy, acidic or peat soils.
The infrequency of yield responses to micronutrient fertilization in Ohio has limited the development of reliable soil and plant tissue tests as diagnostic tools that can accurately predict when to apply micronutrient fertilizer.
Accordingly, farmers should use all available tools to monitor micronutrient availability in their fields including: scouting for visual deficiency symptoms, soil testing and plant analysis, monitoring yield maps and assessing environmental conditions.
When considering micronutrient fertilization, it is always a good idea to leave an unfertilized strip as a check or control. This will allow you to compare areas that received a micronutrient fertilizer vs. an area that did not. Yield monitors or weigh wagons can help you determine if the micronutrient fertilization increased yield and provided an economic benefit.

: Micronutrients| Micronutrients: Types, Functions, Benefits and More | In contrast to macronutrients — which include energy, protein, and fat — micronutrients are vitamins and minerals that are consumed in small quantities but are nonetheless essential for physical and mental development. Essential micronutrients include, but are not limited to: iron, zinc, calcium, iodine, vitamin A, B vitamins, and vitamin C. Deficiencies in these micronutrients are an important global health issue. They can result in poor physical and mental development in children, vulnerability or exacerbation of diseases, mental retardation, blindness, and general losses in productivity and potential. Unlike energy-protein undernourishment, the health impacts of micronutrient deficiency are not always acutely visible. In addition, over two-thirds of non-pregnant women of reproductive age are micronutrient deficient in at least one of iron, zinc, and folate — also known as vitamin B 9. This topic page explores global trends in key micronutrient deficiencies, potential health and development impacts, and progress in interventions to address vitamin and mineral deficiencies. Related topics:. Other research and writing on Micronutrient Deficiency on Our World in Data:. Pregnant women and young children are at greatest risk of developing deficiencies, although any individual can experience micronutrient deficiency. This is not only because of low dietary intake, but also from higher physiological requirements — pregnancy and childhood development often increase demand for specific vitamins and minerals. Therefore, monitoring and addressing micronutrient deficiencies in both pregnant women and young children is essential for healthy development. Data on deficiency prevalence, impacts, and intervention strategies therefore tend to be focused on pregnant women and young children. Much of the content that follows is therefore focused on but not limited to malnutrition in pregnant women and children under the age of five. Anemia can result from a lack of iron or vitamin B 12 , although iron deficiency is the most common type. In more serious cases, anemia can exacerbate disease and illness. It is also responsible for a considerable share of maternal deaths. In the chart, we see the prevalence of anemia in pregnant women. Globally, around a third of pregnant women worldwide are anemic. Rates are particularly high across South Asia and sub-Saharan Africa. In the chart, we see the prevalence of anemia in women of reproductive age. In the chart, we see the prevalence of anemia in children under the age of five. Globally, around four-in-ten children have anemia. Vitamin A is a key nutrient for the development of embryos during pregnancy, the development of the immune system, and vision. It is found in many foods including green leafy vegetables, yellow vegetables and fruits, dairy products, fish, and eggs. Vitamin A deficiency is the leading cause of preventable blindness in children globally. Vitamin A deficiency also exacerbates serious disease and illness, leading to increased rates of maternal and childhood mortality. In the map, we see the prevalence of vitamin A deficiency in pregnant women, during the period from to Data collection on micronutrient deficiencies is often sporadic and less consistent than indicators of energy-protein malnutrition — time-series data for most countries is therefore unavailable. Prevalence rates are typically highest across Africa and Asia. The prevalence across Central Europe and Latin America is much lower, with a small share of pregnant women estimated to be deficient. Vitamin A deficiency can, in some cases, result in visual impairment or blindness. In moderate form, this is limited to night blindness, but in severe cases, it can become permanent. In the map, we see the prevalence of night blindness in pregnant women. Compared to the prevalence of vitamin A deficiency, these figures are lower — not all cases of deficiency result in night blindness. The prevalence of night blindness in most countries is low. However, several countries across sub-Saharan Africa and South Asia record much higher rates. In the map, we see the prevalence of vitamin A deficiency in children under the age of 5, during the period from to Prevalence rates are typically highest across sub-Saharan Africa and South Asia — over half of children in many countries in these regions are deficient. By , the prevalence across Central Europe and Latin America is lower than in Africa and Asia, but still with a sizeable share of children deficient for vitamin A. In the map, we see the prevalence of night blindness in children younger than 5 years old over the period — The prevalence of night blindness is under 1 percent in many countries, but is much higher in some countries in central Africa and central Asia. Zinc is an essential nutrient for the immune system, and is used to make DNA and protein in our body. It is found in whole grains, beans, fortified cereals, meat, fish, poultry, and seafood. Zinc is needed for growth and recovery, and deficiencies can therefore stunt growth, increase susceptibility to disease and infection, and impair recovery, and is associated with higher mortality in mothers and newborns. Zinc deficiency can have several negative health consequences that affect many parts of the body, including the central nervous system, the skeleton, the digestive system, the immune system, and other systems. Globally, zinc deficiency is very common — particularly in lower-income countries where diets are cereal-dominant and typically lower in protein. Zinc deficiency is prevalent in men, women, and children — in contrast to anemia, which is much more common in women. In the chart below, we see the prevalence of zinc deficiency across the whole population. In many high-income countries, under ten percent of the population have zinc deficiency. Across sub-Saharan Africa and South Asia, the prevalence is much higher, with a sizable share of the population in many countries being deficient. Since there are a range of micronutrient deficiencies and nutritional outcomes we can measure, it is difficult to distill the severity of micro-malnutrition into a single measure. One metric that has been developed to indicate the severity of this is the Global Hidden Hunger Index GHHI. Note that the terms 'hidden hunger' and 'micronutrient deficiency' are often used interchangeably. The GHHI is most commonly used to assess the nutritional status of preschool children under the age of five. The GHHI is calculated as the average of three nutritional indicators in preschool children: the prevalence of stunting children who are too short for their age , anemia, and vitamin A deficiency. In the map, we see national GHHI values during the period between and The remaining countries in these regions typically fall within the 'moderate-to-severe' range. If micronutrient requirements cannot be met through dietary intake alone — for example, if households do not have access to, or cannot afford, the dietary diversity required to meet micronutrient requirements — then three other strategies can be used to address deficiencies. These are supplementation, food fortification, and biofortification. As covered earlier in this topic page, children under the age of 5 are typically the most vulnerable to vitamin A deficiency. Many countries try to tackle this issue by providing vitamin A supplements to children, in the form of high-dose capsules several times per year. In the map, we see the coverage rate of vitamin A supplementation in children aged between 6 months and 5 years. Vitamin A supplementation is defined as being sufficient if a child receives at least two high-dose capsules per year. Vitamin A supplementation is relatively common in many countries in Africa and South Asia, although some countries still have low rates of supplementation. Iodine deficiency is a major cause of preventable brain damage in childhood. It can result in stillbirths and the deaths of young infants, mental disability, and thyroid impairments. In the mids, the world committed to ending global iodine deficiency. Iodine deficiency results from diets low in iodine, which is more common in places where soils have low iodine content, which reduces iodine concentrations in crops generally. Iodine deficiency is therefore hard to address simply through dietary diversification. The global solution to addressing deficiency has been through Universal Salt Iodization USI programs. Salt is used as a delivery device for iodine for several reasons: it is widely consumed and has little seasonal variation, it is typically distributed from a few centralized production centers, it has little impact on the taste or texture of foods, and it is cheap. Since the WHO and UNICEF recommended Universal Salt Iodization to address iodine deficiency, the world has made significant progress. Providing zinc supplementation to children younger than 5 years appears to be a highly cost-effective intervention in low- and middle-income countries 18, When children are about 6 months old, it is important to start giving them foods with zinc.

| Micronutrients have major impact on health | Fortifying salt with iodine successfully increases intake of iodine. Folate Everyone needs folate vitamin B9 to make new cells every day. Folate is essential in the earliest days of fetal growth for healthy development of the brain and spine Folic acid is another form of vitamin B9. Women of reproductive age need micrograms of folic acid every day Ensuring sufficient levels of folate in women prior to conception can reduce neural tube defects such as spina bifida and anencephaly Providing folic acid supplements to women years and fortifying foods such as wheat flour with folic acid reduces the incidence of neural tube defects and neonatal deaths Folate is especially important before and during pregnancy. Zinc Zinc promotes immune functions and helps people resist infectious diseases including diarrhea, pneumonia and malaria 14,15, Zinc is also needed for healthy pregnancies Globally, Providing zinc supplements reduces the incidence of premature birth, decreases childhood diarrhea and respiratory infections, lowers the number of deaths from all causes, and increases growth and weight gain among infants and young children Providing zinc supplementation to children younger than 5 years appears to be a highly cost-effective intervention in low- and middle-income countries 18, When children are about 6 months old, it is important to start giving them foods with zinc.

Micronutrients -
Jill Weisenberger is a nutrition writer for Innerbody Research. She is a registered dietitian nutritionist, certified diabetes care and education specialist, certified health and wellness coach, and author of four wellness books.
Micronutrients are those nutrients we require in relatively small quantities. They are vitamins and minerals, and our good health requires them in milligram and microgram amounts. Recall that fats, carbohydrates and proteins are macronutrients , meaning that we require them in relatively large quantities.
We consume the macronutrients in gram amounts. For example, we might have grams of carbohydrate, grams of protein and 50 grams of fat, yet only 18 mg of iron and micrograms of folate.
Vitamins are carbon-containing molecules and are classified as either water-soluble or fat-soluble. They can be changed and inactivated by heat, oxygen, light and chemical processes.
The amount of vitamins in a food depends on the growing conditions, processing, storage and cooking methods. Minerals do not contain carbon, and are not destroyed by heat or light.
Unlike other nutrients, minerals are in their simplest chemical form. Minerals are elements. Whether found in bone, seashells, cast iron pots or the soil, they are the same as the minerals in our food and our bodies.
The mineral content of plant foods varies with the soil content and the maturation of the plant. If you look to vitamins for a jolt of energy, you are looking in the wrong place - even if a supplement bottle says, "promotes energy," or makes some other similar vague statement.
Vitamins are not energy boosters. Many B vitamins do, however, participate in energy-yielding chemical reactions in the body. This is confusing because calorie is another word for energy. It's clearer to say that B vitamins help the body get calories from food. While you're unlikely to get more pep by taking vitamins, eating vitamin-rich foods will certainly help you maintain health.
Niacin assists in carbohydrate and fat metabolism; helps with cell differentiation; and participates in DNA replication and repair. Vitamin B6 assists in protein and carbohydrate metabolism; and supports blood cell synthesis and neurotransmitter synthesis. Vitamin B12 participates in the metabolism of folate.
It helps protect the myelin sheath, the coating that surrounds and protects nerve fibers. Folate assists in DNA synthesis and cell division; participates in amino acid metabolism; and is required for the maturation of cells including red blood cells. Vitamin C is important for many reasons.
It enhances iron absorption. It helps with collagen synthesis. It acts as an antioxidant and plays a role in immune function. It also regenerates vitamin E and assists in the synthesis of neurotransmitters, DNA and hormones. Fat-soluble vitamins accumulate in the liver and fat tissues.
These reserves may be released when dietary intakes are low. There is research, however, suggesting that blood levels of vitamin D may be low even in the presence of significant storage in the fat. Our bodies require vitamin A for night vision and color vision, but that's not all.
We need it for cell differentiation and bone health too. It supports immune function. Vitamin A also aids both male and female reproductive processes.
Major minerals are the ones that the body requires in amounts of at least milligrams per day. They are sodium, potassium, chloride, phosphorus, calcium, magnesium and sulfur. The first four are included in the discussion of fluid and electrolytes.
You may know about calcium as a major component of bones and teeth, but did you know that it's required for muscle contraction as well as nerve transmission? It even plays a role in cellular metabolism and helps with blood clotting. People are often less familiar with the role of magnesium, though it assists enzymes in more than chemical reactions in the body.
Like calcium, it is a component of bone, participates in muscle contraction and aids in blood clotting. Magnesium supports cell activity, too. A component of some vitamins and amino acids, sulfur helps maintain acid-base balance and assists in some of the liver's drug-detoxifying pathways.
The minerals that the body requires in amounts less than milligrams per day are referred to as trace minerals. They are chromium, copper, fluoride, iodine, iron, manganese, molybdenum, selenium and zinc. Because iron metabolism is the most complicated of the nine, it will be discussed in greater detail.
Iron carries oxygen throughout the body - a pretty big responsibility! It assists in energy metabolism and other enzyme-mediated chemical reactions. Iron not only participates in the development of the brain and nervous system, but it's also involved in the production of neurotransmitters, chemicals that carry messages between nerve cells.
It supports immune function as well. The UL for males and females aged 14 and above is 45 mg. It is 40 mg for younger individuals. Side effects of too much iron are gastrointestinal and include nausea, vomiting, diarrhea and constipation.
Immediate emergency medical care is critical because death can occur quickly. In addition to gastrointestinal symptoms, the child may experience rapid heartbeat, dizziness and confusion. Hemochromatosis is a genetic defect that causes excessive iron absorption. Over time, iron can accumulate in and cause damage to various parts of the body.
The result could be diabetes, liver cancer , cirrhosis of the liver and joint problems. Advances in genetic science allow us, through DNA health testing , to find out if our genes predispose us to higher risk of developing hemochromatosis. Iron deficiency is the most common nutrient deficiency throughout the world.
In the U. These include young children over 6 months of age, adolescents, menstruating women and pregnant women. Because they consume no heme iron, vegetarians are also at increased risk.
Iron deficiency results in anemia with symptoms ranging from fatigue to rapid heart rate to decreased tolerance to cold to decreased athletic performance. Pica, the eating of clay, paper, ice and other non-food items, especially during pregnancy, may also be a symptom of iron deficiency.
Chromium enhances the effects of insulin, and may thus, play a role in the development of glucose intolerance and type 2 diabetes. Whole grains, brewer's yeast, nuts and dark chocolate are sources of chromium. Clinical assessment of chromium status is difficult.
Copper assists with the transport of iron. Rich sources of copper include liver, shellfish, legumes, nuts and seeds. Deficiencies or excesses of copper are rare in healthy people. Fluoride helps prevent dental caries. The main source of fluoride is municipal water supplies that add fluoride to the water.
Excess fluoride discolors and damages teeth. Iodine is a component of the thyroid hormones, which regulate metabolic rate and body temperature. Sources of iodine include saltwater fish, liver, legumes, potatoes, iodized salt and dairy products. Iodine deficiency inhibits the synthesis of thyroid hormones resulting in hypothyroidism and it's typical problems including fatigue, weight gain and intolerance to cold.
In recent years, the use of iodized salt has decreased deficiency cases. Under different circumstances, excess iodine can cause either hyperthyroidism or hypothyroidism. Both too little and too much iodine can cause goiter, an enlargement of the thyroid gland.
Manganese is important in many enzyme-mediated chemical reactions including enzymes involved in the synthesis of cartilage in skin and bone.
Tea and coffee are significant sources of manganese in the American diet. Additional sources are nuts, whole grains, legumes and some fruits and vegetables. Magnesium deficiency is rare. Toxicity is also uncommon and is most frequently the result of exposure to airborne manganese dust.
The UL for manganese is 11 mg per day. Molybdenum assists several enzymes including one required for the metabolism of sulfur-containing amino acids. Peas, legumes and some breakfast cereals supply molybdenum.
Both molybdenum deficiency and toxicity are rare. High doses of molybdenum, however, inhibit copper absorption. Selenium is required for immune function and for the synthesis of thyroid hormones.
Additionally, this mineral assists enzymes in protecting cell membranes from damage. Depending upon the soil in which they are grown, Brazil nuts are one of the richest sources of selenium.
Organ meats, seafood, other meats and whole grains are additional sources. Low selenium intake may decrease an individual's ability to fight viral infections. Some research also links low intakes to some cancers.
Toxicity causes brittle hair and nails and is most likely to occur with supplements. Zinc is critical for normal growth and sexual maturation. It plays a role in the immune system and is important to the proper function of at least 70 enzymes including one that helps protect cells from damage.
Oysters, beef and clams are rich sources of absorbable zinc. Whole grains also contain zinc, but it is less available for absorption. Zinc deficiency causes delayed growth and sexual development, decreased immune function, altered sense of taste, hair loss and gastrointestinal distress.
Zinc deficiency is uncommon in healthy people in the U. It is more common among populations that consume cereals as their primary source of nutrition. Zinc toxicity is rare. Micronutrients play crucial roles in growth and development from the earliest stages of human development and on—from fetuses to infants, children, and adults.
They are required for optimal nutrition, and they support many body structures and processes. For example, folate vitamin B9 helps prevent some congenital present at birth conditions , make DNA and other genetic materials, and is needed for cell division. Iodine is important for early cognitive development and thyroid health.
Some micronutrients, including vitamins A, C, and E, copper, zinc, and selenium, act as antioxidants , which help protect the body against oxidative stress due to excess free radicals byproducts of turning food into energy.
Free radicals can damage organs, tissues, and genetic materials. Each micronutrient has different roles in keeping the body growing and functioning properly. Deficiency can throw off the balance and lead to a host of problems. Micronutrient deficiencies can cause visible and life-threatening health conditions.
But there may also be less noticeable symptoms, including decreased energy, mental sharpness, and overall day-to-day functioning. These harder-to-spot symptoms can lead to trouble learning, decreased work productivity, and increased risk of infection and other diseases.
Some micronutrient deficiencies are prevalent around the globe, especially in developing countries. According to the Centers for Disease Control and Prevention CDC , at least half of children worldwide younger than 5 years of age are affected by micronutrient deficiencies.
Below are six common worldwide micronutrient deficiencies and their associated symptoms:. Below are the amounts of micronutrients needed per day for adults aged 19 or older, based on the recommended dietary allowances RDAs or adequate intakes AIs.
Micronutrients may have established tolerable upper intake levels. Daily ongoing intake below these levels should not pose a significant health risk, but exceeding the level may. These are established for different age groups.
While food sources rarely lead to exceeding the tolerable upper intake limit for micronutrients, taking supplements can lead to excess. Check any dietary supplements for proper dosage and talk with a healthcare provider about your needs and limits.
Micronutrients are vitamins and minerals required by the body for many processes, growth, and functioning. They are found in every food group, including fruits, vegetables, grains, dairy, proteins, and fats. Eating a variety of foods each day is the best way to get all the micronutrients you need.
Micronutrients are required for optimal nutrition and immune function, and support many body structures and processes, as well as help protect against diseases and other health conditions. Symptoms of a deficiency depend on the vitamin or mineral that is lacking in the body and can range from mild to serious.
Amounts of micronutrients needed daily also vary and are specific to each vitamin or mineral. National Institutes of Health, Office of Dietary Supplements. Vitamin A and carotenoids. Vitamin D. Vitamin E. Vitamin K. Vitamin C. Pantothenic acid. Vitamin B6. Vitamin B Harvard School of Public Health.

Micronutrients, Ginseng tea benefits known as Mocronutrients and minerals, are vital to overall Micornutrients and well-being. Ginseng tea benefits are important for functions such as blood-clotting, brain development, Micronutrinets system Ginseng tea benefits, energy Micronutients, and bone BCAA and muscle energy production. They play critical roles in disease prevention. A few micronutrients are vitamins A, C, and D and the minerals iron, potassium, and calcium. This article discusses micronutrients in food, the need for micronutrients, symptoms of micronutrient deficiency, and how many micronutrients are needed daily. Vitamins and minerals can be classified as fat-soluble vitamins, water-soluble vitamins, macrominerals, and trace minerals. Fat-soluble vitamins do not dissolve in water and are best absorbed when taken along with a source of fat.Micronutrients -

Iron Iron is critical for motor and cognitive development. Children and pregnant women are especially vulnerable to the consequences of iron deficiency 3.
Iron deficiency is a leading cause of anemia which is defined as low hemoglobin concentration. Anemia during pregnancy increases the risk of death for the mother and low birth weight for the infant. Worldwide, maternal and neonatal deaths total between 2. Babies fed only breast milk, only formula, or a mix of breast milk and formula have different needs when it comes to iron.
Preventing iron deficiency helps improve children's learning ability and cognitive development. Vitamin A Vitamin A supports healthy eyesight and immune system functions. Children with vitamin A deficiency face an increased risk of blindness and death from infections such as measles and diarrhea 6.
Globally, vitamin A deficiency affects an estimated million preschool-age children 6. Providing vitamin A supplements to children ages months is highly effective in reducing deaths from all causes where vitamin A deficiency is a public health concern 6.
Vitamin D Vitamin D builds strong bones by helping the body absorb calcium 7. This helps protect older adults from osteoporosis. Vitamin D deficiency causes bone diseases, including rickets in children and osteomalacia in adults 7. Vitamin D helps the immune system resist bacteria and virsues 7.
Vitamin D is required for muscle and nerve functions 7. Available data suggest that vitamin D deficiency may be widespread globally 8. Bodies make vitamin D from sunlight, but this varies based on geography, skin color, air pollution, and other factors.
Also, sunlight exposure needs to be limited to avoid risk of skin cancer. All children need vitamin D beginning shortly after birth. Globally an estimated 1. Iodine content in most foods and beverages is low. The amount of iodine added to salt can be adjusted so that people maintain adequate iodine intake even if they consume less salt The American Thyroid Association and the American Academy of Pediatrics recommend that pregnant or breastfeeding women take a supplement every day containing micrograms of iodine.
The American Thyroid Association recommends women who are planning a pregnancy consume a daily iodine supplement starting at least 3 months in advance of pregnancy. Fortifying salt with iodine successfully increases intake of iodine.
Folate Everyone needs folate vitamin B9 to make new cells every day. Folate is essential in the earliest days of fetal growth for healthy development of the brain and spine Folic acid is another form of vitamin B9.
Women of reproductive age need micrograms of folic acid every day Ensuring sufficient levels of folate in women prior to conception can reduce neural tube defects such as spina bifida and anencephaly Providing folic acid supplements to women years and fortifying foods such as wheat flour with folic acid reduces the incidence of neural tube defects and neonatal deaths Folate is especially important before and during pregnancy.
Zinc Zinc promotes immune functions and helps people resist infectious diseases including diarrhea, pneumonia and malaria 14,15, Zinc is also needed for healthy pregnancies Globally, Providing zinc supplements reduces the incidence of premature birth, decreases childhood diarrhea and respiratory infections, lowers the number of deaths from all causes, and increases growth and weight gain among infants and young children Providing zinc supplementation to children younger than 5 years appears to be a highly cost-effective intervention in low- and middle-income countries 18, When children are about 6 months old, it is important to start giving them foods with zinc.

Subclinical deficiency, often of multiple micronutrients, is more difficult to recognise, and laboratory assessment is often complicated by the acute phase response. Clinical benefit is most likely in those people who are severely depleted and at risk of complications, and is unlikely if this is not the case.
There is little evidence for supplements leading to a reduction in the incidence of infections in the elderly population, in coronary artery disease, or in malignant disease. The best evidence for benefit is in critical illness, and in children in developing countries consuming a deficient diet.
More clinical trials are required with good clinical outcomes to optimise intake in prevention and treatment of disease.
