Manganese is an essential mineral for human health that plays a crucial role in the proper functioning of many enzyme systems in the body. It is found in trace amounts in plants, animals, and soil. Manganese is also used in the production of steel, aluminum, and batteries.

The recommended dietary intake of manganese for adults is 1.8-2.3 milligrams per day. However, many individuals do not consume enough manganese in their diets. Symptoms of manganese deficiency may include impaired growth, reproductive problems, and skeletal abnormalities.

Manganese is necessary for the production of several important enzymes, including superoxide dismutase, which protects cells against oxidative stress. The mineral also aids in the metabolism of carbohydrates, amino acids, and cholesterol. Manganese is also important for healthy bone development and wound healing.

Despite its importance, excessive intake of manganese may cause neurotoxicity, which can lead to Parkinson’s disease-like symptoms. The risk for excessive manganese exposure is highest in certain industries, such as steel production, where inhalation of manganese dust can occur.

Manganese sources in the diet include nuts, whole grains, leafy green vegetables, and some fruits. Some foods, like tea and chocolate, also contain small amounts of manganese. In addition, some water sources may naturally contain small amounts of the mineral.

The absorption of manganese in the body is influenced by other dietary factors, such as iron and calcium. Consumption of high levels of these minerals may reduce manganese absorption. Conversely, low iron status may increase manganese absorption.

Some studies suggest that manganese may have therapeutic effects in the treatment of certain medical conditions. For example, manganese supplementation has been shown to improve bone health in postmenopausal women. In addition, manganese may help to improve symptoms of premenstrual syndrome.

The use of manganese supplements, however, should only be under the guidance of a healthcare professional. Excessive manganese intake can lead to toxicity, and it is important to have blood levels of manganese monitored regularly.

In conclusion, manganese is an essential mineral for human health that is involved in many enzymatic reactions in the body. The mineral is found in many plant-based foods and some water sources. While manganese deficiency is uncommon, excessive manganese intake can lead to neurotoxicity. As with any supplement, it is important to work with a healthcare professional to ensure safe and appropriate use.
