Manganese is a trace mineral, meaning it is only needed in tiny amounts by the body. Trace minerals are important for overall health and manganese contributes to many health benefits. Let's explore this supplement's advantages for good health.
Key Health Benefits of Manganese
Manganese is used to speed up chemical reactions in the body that involve energy production, fat metabolism and protein metabolism. Because it breaks down fats and proteins, it is useful for supporting those with diabetes, when fat and protein are often called upon as an energy source for the cells.
It is also part of synthesising bone, cartilage and joint fluid. Manganese helps to calm the nervous system, in conjunction with the vitamins of the B complex. Manganese benefits red blood cells by being a component of their antioxidant defences, through the enzyme superoxide dismutase (SOD). Manganese is used by natural health practitioners for a variety of conditions including epilepsy, diabetes, iron-deficiency anemia, and osteoporosis.
Shopping For Quality Manganese Supplements
Chelated manganese supplements are usually found in health food stores. Chelated simply means that manganese is bonded to a protein molecule, for example, aspartate, glycinate, gluconate, picolinate, etc. Manganese is found in tablet form.
Large doses of calcium and phosphorus inhibit the absorption of manganese. Manganese is also not absorbed well when it is taken with high-fibre foods and foods containing phytic acid (legumes), milk and meat.
Potential Side Effects & Considerations
The symptoms of manganese toxicity include tremors, muscle spasms, hearing problems, mania, insomnia, depression, loss of appetite, headaches, irritability, weakness, and mood changes. If you experience these symptoms it is advised to stop taking these supplements and see a health care practitioner if necessary.




While manganese is a trace mineral, it's clear from your article that the little bit of manganese can really matter, with manganese being part of the synthesis of bone, cartilage and joint fluid, too. Also, being important for a type of enzyme superoxide dismutase (MnSOD) means manganese can be important for antioxidant defense, too. Also, thank you for your final note that 1) large doses of calcium & phosphorus inhibit it absorption and 2) Mn is also not absorbed well when it is taken with high fibre foods and foods rich phytic acid (legumes), milk and meat... as a bean lover who supplements with calcium, I'll keep these things in mind!
