Int J Environ Res Public Health. ], which are not documented, were determined to provide guideline values for estimating the Mn status from deficiency through toxicity.Soybean (âBraggâ) was grown in Hoagland nutrient solution with 14 Mn levels from 0 to 50,000 μg/liter.The plants were ⦠While manganese deficiency does not appear to be a cause of epilepsy in humans, the relationship between manganese metabolism and epilepsy deserves further research (7, 29). Manganese (Mn) plays an important role in a number of physiologic processes as a constituent of multiple enzymes and an activator of other enzymes (2). Rev Environ Health. Unlike ingested manganese, inhaled manganese is transported directly to the brain before it can be metabolized in the liver (35). Given that both Fe and Mn are abundant in the earth crust, nutritional deficiency is rare. Boca Raton: CRC Press, Inc.; 1994:145-157. The brain is particularly susceptible to this excess manganese, and accumulation there can cause a neurodegenerative disorder known as manganism. Manganese is a mineral element that is both nutritionally essential and potentially toxic. Ma C, Iwai-Shimada M, Tatsuta N, Nakai K, Isobe T, Takagi M, Nishihama Y, Nakayama SF. Because of the potential for toxicity and the lack of information regarding benefit, manganese supplementation beyond 100% of the DV (2 mg/day) is not recommended.  (PubMed), 45. Vieregge P, Heinzow B, Korf G, Teichert HM, Schleifenbaum P, Mosinger HU.

Hair manganese and hyperactive behaviors: pilot study of school-age children exposed through tap water. Present Knowledge in Nutrition. Dietary Diversity Is Associated With Memory Status in Chinese Adults: A Prospective Study. Because of potential toxicities, some argue against including manganese in parenteral nutrition (52). Because there was insufficient information on manganese requirements to set a Recommended Dietary Allowance (RDA), the Food and Nutrition Board (FNB) of the Institute of Medicine set an adequate intake (AI). In the brain, the manganese-activated enzyme, glutamine synthetase, converts the amino acid glutamate to glutamine. 35. Davis JM. MnSOD catalyzes the conversion of superoxide radicals to hydrogen peroxide, which can be reduced to water by other antioxidant enzymes (3). 1992;5:100-101 (abstract).  (PubMed), 52. Hardy IJ, Gillanders L, Hardy G. Is manganese an essential supplement for parenteral nutrition? Young men who were fed a low-manganese diet developed decreased serum cholesterol levels and a transient skin rash (18). Since overt manganese deficiency has not been documented in humans eating natural diets, the FNB based the AI on average dietary intakes of manganese determined by the Total Diet Study â an annual survey of the mineral content of representative American diets (4). Median intake is between 1.6 and 2.3 mg/day; absorption is 5 to 10%. The toxic effects of manganese in dogs [ 5] and humans [ 6] tend to involve the heart, liver, and nervous system, but some endocrine effects can occur. Manganese deficiency results in glucose intolerance similar to diabetes mellitus in some animal species, but studies examining the manganese status of diabetic humans have generated mixed results. Copper, zinc, manganese, and magnesium status and complications of diabetes mellitus. 44. Toxicol Appl Pharmacol. These and other recent reports have raised concern over the neurobehavioral effects of manganese exposure in children (46). For instance, a cross-sectional study in 142 10-year old children, who were exposed to a mean manganese water concentration of 0.8 mg/L, found that children exposed to higher manganese levels had significantly lower scores on three tests of intellectual function (47). Curr Opin Clin Nutr Metab Care. MMT is a manganese-containing compound used in gasoline as an anti-knock additive. Although teas are rich sources of manganese, the tannins present in tea may moderately reduce the absorption of manganese (15). Oregon State University, Reviewed in March 2010 by: PDR for Nutritional Supplements. The role of manganese in wound healing. However, the presence of other trace elements in the supplement makes it impossible to determine whether manganese supplementation was the beneficial agent for maintaining bone mineral density. While manganese deficiency rarely occurs in humans, manganese toxicity is known to occur in certain occupational settings through inhalation of manganese-containing dust.  (National Academy Press). The adequate intake (AI) for manganese (2.3 mg/day for adult men and 1.8 mg/day for adult women) appears sufficient to prevent deficiency in most individuals.

Iron supplementation (60 mg/day for four months) was associated with decreased blood manganese levels and decreased MnSOD activity in white blood cells, indicating a reduction in manganese nutritional status (11). 7. Manganese is an essential metal that becomes toxic at elevated levels. Low dietary manganese or low levels of manganese in blood or tissue have been associated with several chronic diseases. Manganese is required for the activation of prolidase, an enzyme that functions to provide the amino acid, proline, for collagen formation in human skin cells (8). However, bioavailability of manganese from breast milk is higher than from infant formulas, and manganese deficiencies in breast-fed infants or toxicities in formula-fed infants have not been reported (31). Manganese concentrations in drinking water range from 1 to 100 μg/L, but most sources contain less than 10 μg/L (32). Pyruvate carboxylase, a manganese-containing enzyme, and phosphoenolpyruvate carboxykinase (PEPCK), a manganese-activated enzyme, are critical in gluconeogenesis â the production of glucose from non-carbohydrate precursors. Arginase, another manganese-containing enzyme, is required by the liver for the urea cycle, a process that detoxifies ammonia generated during amino acid metabolism (3). 43. 2018 Jan;112:134-145. doi: 10.1016/j.neuint.2017.10.005. Manganese deficiency has been observed in a number of animal species. A dose-response experiment with different Mn concentrations showed that OsYSL6 expression was not induced by either Mn excess or deficiency in both the roots and shoots (Fig. These findings suggested to us that the Mn-deficient rat may be especially susceptible to the toxic effects of ethanol, as the ⦠This syndrome, often called manganism, is sometimes preceded by psychiatric symptoms, such as irritability, aggressiveness, and even hallucinations (36, 37). Several forms of manganese are found in supplements, including manganese gluconate, manganese sulfate, manganese ascorbate, and amino acid chelates of manganese. The brain is particularly susceptible to this excess manganese, and accumulation there can cause a neurodegenerative disorder known as manganism. Manganese. 1) Manganism (Manganese Toxicity) Overexposure to Mn, usually in the workplace, causes manganism, a syndrome similar to Parkinsonâs disease [ 20, 21 ]. email: lpi@oregonstate.edu, Healthcare Professional Continuing Education. doi: 10.1016/j.heliyon.2020.e04691. 1998;106 Suppl 1:191-201. (PubMed), 36. Pal PK, Samii A, Calne DB.

Current Drinking Water Standards. Due to the severe implications of manganese neurotoxicity, the Food and Nutrition Board (FNB) of the Institute of Medicine set very conservative tolerable upper intake levels (UL) for manganese; the ULs are listed in Table 3 according to age (4). 50. Dobson AW, Erikson KM, Aschner M. Manganese neurotoxicity. Manganese absorption and retention by young women is associated with serum ferritin concentration. Manganese is also quite toxic when ingested in large amounts, such as the inhalation of Mn-laden dust by miners. Following the Linus Pauling Institute recommendation to take a multivitamin/multimineral supplement containing 100% of the daily values (DV) of most nutrients will generally provide 2 mg/day of manganese in addition to that in foods. Additional signs of manganese toxicity in domestic animals can include depressed growth, depressed appetite, and altered brain ⦠(See also Overview of Mineral Deficiency and Toxicity.) 1999;20(2-3):227-238. (PubMed), 37. Aschner M, Aschner JL.

Median intake is between 1.6 and 2.3 mg/day; absorption is 5 to 10%. Women with osteoporosis have been found to have decreased plasma or serum levels of manganese and also an enhanced plasma response to an oral dose of manganese (19, 20), suggesting they may have lower manganese status than women without osteoporosis. Environmental Protection Agency, [Web page]. In women, a manganese deficiency displays prominent mood swings like in the case of cyclothymia, besides complications of premenstrual syndrome. Kisasato Archives of Experimental Medicine. Additionally, more recent studies have shown that children exposed to high levels of manganese through drinking water experience cognitive and behavioral deficits (46). One study found blood manganese levels of individuals with epilepsy of unknown origin were lower than those of individuals whose epilepsy was induced by trauma (e.g., head injury) or disease, suggesting a possible genetic relationship between epilepsy and abnormal manganese metabolism. 1991;4:73-79. 2000;52(2):149-155. (PubMed). J Trace Elem Exp Med. Manganese toxicity resulting from foods alone has not been reported in humans, even though certain vegetarian diets could provide up to 20 mg/day of manganese (4, 32). Additionally, environmental or occupational inhalation of manganese can cause an inflammatory response in the lungs (38). Racette BA, Aschner M, Guilarte TR, Dydak U, Criswell SR, Zheng W.
