Manganese Benefits and Sources

Manganese is a naturally occurring element found in small amounts within the human body, primarily concentrated in the bones, liver, kidneys, and pancreas. It plays a crucial role in various physiological functions, aiding in the development of connective tissue, bones, blood clotting factors, and sex hormones. Additionally, manganese contributes significantly to fat and carbohydrate metabolism, as well as the absorption of calcium and the regulation of blood sugar levels, all of which are essential for maintaining normal brain and nerve function.

When combined with calcium, zinc, and copper, manganese supports bone mineral density, making it particularly beneficial for older adults. Enzymes within the human body expedite chemical reactions, and manganese is a vital component of numerous enzymes responsible for processing carbohydrates, amino acids, and cholesterol.

Manganese is also a key constituent of the antioxidant enzyme superoxide dismutase (SOD), which aids in combating free radicals. These naturally occurring molecules have the potential to cause damage to cell membranes and DNA, contributing to conditions such as aging, heart disease, and certain types of cancers.

Moreover, manganese is present in an enzyme that supplies the amino acid proline, necessary for synthesizing collagen in skin cells, a crucial factor in wound healing. Furthermore, manganese collaborates with various other enzymes that promote bone and cartilage growth, facilitate insulin production for blood sugar regulation, and support blood clotting.

Manganese is considered an essential nutrient and is predominantly found in seeds and whole grains, with smaller quantities present in legumes, beans, nuts, leafy green vegetables, and tea.
Manganese Benefits and Sources

Food sources of manganese

Estimated average dietary manganese intakes in the United States range from 2.1 to 2.3 mg/d for men and 1.6 to 1.8 mg/d for women.

The best food sources of manganese are of plant origin. Tea, coffee, nuts, cereals and some fruits are the best food sources of manganese. Some estimates suggest that coffee or tea supplies as much as 20 to 30 percent of our daily manganese intake.

People eating vegetarian diets and Western diets emphasizing whole grains may have manganese intakes as high as 10.9 mg/d.

Fair sources of manganese are brewer’s yeast, liver, most fruits and vegetables, orange pekoe tea and white enriched bread.  Dairy products, meat fish and poultry are poor sources of manganese.

Manganese toxicity

Manganese is widely distributed in the biosphere: it constitutes approximately 0.085% of the Earth’s crust, making it the twelfth most abundant element. Exposure to high levels of oral, parental and air manganese may result in toxicity.

Manganese toxicity in humans is primary a concern for those exposed to high airborne concentration in the workplace, especially industrial workers and miners.

Severe neurological damage has been observed in inhabitants of Groote Eylandt, an island in the Gulf of Carpentaria off the north coasts of Australia which contains one of the world’s richest manganese mines.

In addition to neural damage, reproduction and immune dysfunction, nephritis, testicular damage, pancreatitis, lung disease, and hepatic damage can occur with manganese toxicity, though the frequency of these disorders in unknown. Manganese toxicity can result in a permanent neurological disorder known as manganese with symptoms that include tremor, difficulty walking and facial muscle spasms.

In the milder form, toxicity is expressed by hyperirritability, violent acts, hallucinations, disturbances of libido and coordination.

Cases of manganese toxicity in humans have reported only for adults; however, it has been suggested that infants may be at high risk for manganese toxicity due to a high absorptive capacity for the element and/or an immature excretory pathway for it.

Additionally, individuals with liver failure are at greater risk for toxicity because manganese homeostasis is maintained largely by lover though excretion in the bile.

The symptoms of manganese toxicity may appear slowly over months and years.

Deficiency of manganese

A deficiency of manganese (which is extremely rare) may lead to atherosclerosis, confusion, eye problems, hearing problems, heart disorders, high cholesterol levels, hypertension irritability, memory loss, muscle contradiction, pancreatic damage, profuse perspiration, rapid pulse, teeth grinding, tremors and a tendency towards breast ailments.

Although people who consume normal varied diets do not appear to be at risk for manganese deficiency, certain disorders may cause suboptimal status.

Manganese deficiency has been shown to lead to bone demineralization and impaired growth in children, decreased serum cholesterol levels and a transient skin rash in young men, and mildly abnormal glucose tolerance in young women.
Deficiency of manganese

Manganese in Our Body

Minute quantities of manganese are needed for protein and fat metabolism, healthy nerves, a healthy immune system, and blood sugar regulation.

Body contains between 10 to 20 milligram of manganese, which is concentrated primarily in the bone, liver, pancreas and brain.

Manganese is used in energy production and is required for normal bone growth and for reproduction.

In addition, it is used in the formation of cartilage and synovial (lubricating) fluid of the joints. It is also necessary for the synthesis of bone.

Too little dietary manganese causes impaired skeletal development and reproduction, abnormal carbohydrate and lipid metabolism, and movement disorders.

Manganese is essential for people with iron deficiency anemia and is needed for the utilization of vitamin B1 (thiamine) and vitamin E.

Manganese works well with the B complex vitamins to give as overall feeling of well being.

Manganese is found in many essential enzymes, which are biologically important compounds. Enzymes in the body speed up crucial chemical reactions.

It aids in the formation of mother’s milk and is a key element in the production of enzymes needed to oxidize fats and to metabolize purines, including the antioxidant enzymes superoxide dismutase.

Enzymes containing manganese protect the body from harmful oxygen radicals, highly reactive oxygen containing molecules that can damage living tissues.

Absorption of manganese is poor, only 1 to 15 percent. The high levels of iron, calcium an phosphorus may inhibit absorption.

Following absorption, transferring binds manganese and transport it in the bloodstream.

Manganese

Manganese
Most of the manganese in our body is in glands, (pituitary, mammary, pancreas) organs (liver, kidney, intestines) and bones. Manganese is an essential constituent of the enzymes that metabolize carbohydrates and synthesize fats (including cholesterol).

Manganese is important for a healthy reproduction system. During pregnancy, manganese speeds the proper growth of fetal tissue, particularly bones and cartilage.

We can get manganese from whole grains, cereal products fruit and vegetables. Tea also a good source of manganese.

Manganese Deficiency
Although people who consume normal varied diets do not appear to be at risk for manganese deficiency, certain disorders may cause sub-optional status.

Manganese deficiency has been shown to lead to bone demineralization and impaired growth in children, decreased serum cholesterol levels and a transient skin rash in young men, and mildly abnormal glucose tolerance in young women.

In animals studies, manganese deficiency has dramatic, effects: impact growth, skeletal abnormalities, impaired glucose tolerance, impaired reproductive system, and altered carbohydrate and fat metabolism.

Manganese Toxicity
Manganese toxicity is a greater threat than manganese deficiency. Foundry workers exposed to airborne manganese dust have experienced severe manganese toxicity.

Their symptoms included irritability, hallucinations and severe lack of coordination. Lower does of airborne manganese can impair memory and cause impaired motor coordination similar to that experienced in Parkinson’s disease.
