What You'll Learn

Manganese is an essential trace mineral
Manganese is involved in various chemical processes within the body. It aids in metabolism, helps regulate blood sugar levels, contributes to reduced inflammation, and supports bone health. Manganese works alongside other nutrients like calcium, zinc, copper, and vitamin K to promote bone mineral density and wound healing.
The mineral is also a key component of the antioxidant enzyme superoxide dismutase (SOD). SOD protects the body from free radicals, which are harmful molecules that can damage cells. By breaking down these free radicals into smaller, less harmful components, manganese helps prevent cell damage caused by ageing and lifestyle activities, thereby reducing the risk of chronic diseases associated with inflammation and cell damage, such as osteoporosis.
Manganese-rich foods include whole grains, seeds, nuts, legumes, and certain fruits and vegetables. Examples include chickpeas, spinach, pineapple, mussels, brown rice, whole wheat bread, black tea, and potatoes with the skin. However, it is important to note that excessive manganese intake could lead to high levels of the mineral in body tissues, particularly the brain, which may be associated with neurological disorders. Therefore, while manganese is essential, it should be consumed in moderation, and individuals with certain medical conditions, such as liver or kidney disease, should be cautious and consult their healthcare providers.

It aids metabolism and regulates blood sugar
Manganese is a trace mineral that is essential to our bodies in small amounts. It is a coenzyme that assists many enzymes involved in breaking down carbohydrates, proteins, and cholesterol. Manganese also aids in building bones and contributes to the health of the immune and reproductive systems.
Manganese is important for maintaining healthy metabolism and blood sugar levels. It helps the pancreas create insulin, which is crucial for regulating blood sugar. This is particularly relevant for people with diabetes, as manganese may assist in lowering blood sugar levels. A 2014 study in South Korea found that individuals with diabetes had lower levels of manganese in their bodies. However, it is unclear if this is a causal relationship or a result of the disease.
Additionally, manganese may help reduce the risk of chronic diseases linked to cell damage and inflammatory conditions. It stimulates antioxidant activity in cells, protecting them from damage caused by aging and lifestyle activities. This antioxidant activity is due to manganese's role in forming the enzyme superoxide dismutase (SOD), which breaks down free radicals into smaller, less harmful molecules.
Manganese-rich foods include whole grains, seeds, nuts, legumes, beans, leafy green vegetables, and tea. It is generally safe to consume manganese through dietary sources, and it is rare to experience any side effects. However, excessive intake or inhalation of manganese should be avoided, as it can lead to potential health risks and nervous system damage.

Manganese is important for bone health
Manganese is a trace mineral that is essential to our bodies in small amounts. It is a coenzyme that assists many enzymes involved in breaking down carbohydrates, proteins, and cholesterol. It also assists enzymes in building bones and keeping the immune and reproductive systems functioning optimally.
Manganese can be found in whole grains, seeds, nuts, legumes, and tea. Some examples of manganese-rich foods include whole wheat bread, chickpeas, lentils, kidney beans, spinach, kale, pineapple, blueberries, apples, mussels, oysters, clams, and brown rice.
While manganese is essential for bone health, it is important to note that excessive consumption may be dangerous as it is considered a heavy metal. The recommended daily intake of manganese for adults is 2.3 mg for men and 1.8 mg for women, with a safe upper limit of 11 mg for adults aged 19 and older.

It helps with wound healing
Manganese is a trace mineral that is essential to our bodies in small amounts. Our bodies cannot produce manganese, so we must obtain it from our diet or supplements. Manganese is a coenzyme that assists many enzymes involved in breaking down carbohydrates, proteins, and cholesterol. It also plays a role in building bones and keeping the immune and reproductive systems healthy.
One important role of manganese in the body is its contribution to wound healing. Wound healing requires increased collagen production, and manganese is necessary for producing the amino acid proline, which is essential for collagen formation in human skin cells. Early research indicates that applying manganese, calcium, and zinc to chronic wounds for 12 weeks may improve healing. However, more studies are needed to confirm the effect of manganese on wound healing.
Manganese also supports wound healing by assisting in blood clotting. Blood clotting is the first stage of wound healing, as it helps keep the blood in a damaged blood vessel, preventing excessive blood loss. Manganese works together with vitamin K in this process, helping to clot the blood and initiate the wound healing process.
Additionally, manganese stimulates antioxidant activity in our cells, which protects them from damage caused by ageing and lifestyle activities. This antioxidant effect is due to manganese's role in forming the enzyme superoxide dismutase (SOD). SOD breaks down free radical molecules, such as superoxide, into smaller, less harmful components. By reducing cell damage, manganese helps lower the risk of chronic diseases associated with inflammation and cell damage, including inflammatory conditions like osteoporosis.
Manganese is found in various foods, including whole grains, nuts, seeds, wheat germ, legumes, pineapples, and tea. It is generally safe to consume manganese from dietary sources, and it is rare to experience any side effects. However, excessive intake of manganese, especially through inhalation or in individuals with certain medical conditions, can lead to potential health risks. Therefore, it is important to stay within the recommended intake levels and consult a healthcare provider before taking supplements.

Manganese is a powerful antioxidant
Manganese is a component of an antioxidant called superoxide dismutase (SOD). SOD protects against cell damage caused by free radical molecules. It breaks down the free radical superoxide into smaller, less harmful molecules. By preventing cell damage, SOD may reduce the risk of chronic diseases linked with cell damage and inflammatory conditions like osteoporosis.
Manganese also contributes to overall health by aiding metabolism, helping regulate blood sugar, reducing inflammation, and decreasing premenstrual cramps. Adequate manganese intake is important, but it is not recommended to take more than needed as it is considered a heavy metal, and excess consumption may be dangerous. Manganese is found in whole grains, nuts, seeds, wheat germ, legumes, and pineapples, so it is fairly easy to get enough in your diet.
However, some experts estimate that up to 37% of Americans do not get the recommended dietary intake (RDI) of manganese. This may be due to the American diet's emphasis on refined grains, which contain only half the manganese of whole grains. Manganese deficiency is rare, but it can cause weak bones in children and skin rashes or mood changes in adults.
