Manganese is a trace mineral that is needed in small amounts for the body to function properly. Despite its relatively low concentration in the body, manganese plays a crucial role in numerous physiological processes. It acts as a cofactor for various enzymes involved in energy metabolism, bone development, antioxidant defence, and neurotransmitter synthesis. Therefore, adequate manganese intake is essential foroptimal health and well-being.
Dietary sources of manganese include whole grains, nuts, seeds, legumes, leafy green vegetables, and some fruits. A balanced and varied diet can usually provide sufficient manganese to meet the body's needs. In some cases, individuals with specific dietary restrictions or malabsorption issues may require supplementation under the guidance of a healthcare professional. The recommended daily allowance (RDA) for manganese varies depending on age and sex but generally ranges from 1.8 to 2.3 milligrams per day for adults.
Manganese deficiency is relatively rare in developed countries due to the widespread availability of manganese-rich foods. However, individuals with certain medical conditions or those consuming highly restrictive diets may be at increased risk. Symptoms of manganese deficiency can include impaired growth, skeletal abnormalities, altered glucose metabolism, neurological disturbances, and reproductive dysfunction. Conversely, excessive manganese intake, primarily through occupational exposure or contaminated water sources, can lead to neurotoxicity, manifesting as Parkinson-like symptoms. Therefore, maintaining a balanced manganese intake is crucial for optimal health and disease prevention.
