VITAMIN, MINERAL & TRACE ELEMENT GUIDE
Manganese.
TRACE ELEMENT
Manganese forms a part of many enzymes in our body. These enzymes are involved in a range of functions including metabolism, bone health, the function of certain B vitamins, the production of sex hormones, and it also forms a part of certain antioxidants enzymes.


There are tens of thousands of chemical reactions that occur in our body. Some digest our food, while others maintain our metabolism and general functioning. These reactions need to be strictly controlled and enzymes are responsible for this. Enzymes initiate the reaction at precisely the right time; they maintain it at the right speed; and they bring it to a halt once it’s done. They regulate many fundamental processes in our body and they need the right nutrients to do so; manganese is one of them.


Manganese is involved with antioxidant enzymes that help to counter the damaging effects of free radicals. It’s also needed by enzymes that help with the metabolism of carbohydrates, proteins and cholesterol. This in turn helps us to maintain blood sugar balance and healthy blood cholesterol levels. Manganese also helps in the function of B-vitamins and the production of sex hormones; it’s required by enzymes that help to build and maintain our bone health; and it also assists in wound healing. Manganese has many functions that are integral to our health. It definitely earns it keep inside our body.


Deficiency

A manganese deficiency is rare in well nourished and healthy individuals. It’s present in a wide variety of foods, so eating a balanced diet is the best way to ensure we are getting the right dose. Manganese deficiency, along with other nutrient deficiencies, is seen in malnourished populations, in those with extreme eating disorders, or those with other underlying health problems.


A manganese deficiency will effect the enzymes that rely on it and the processes and organs they maintain. Signs of a manganese deficiency include, reduced bone strength and density, joint problems, a change in cholesterol and carbohydrate metabolism characterized by low cholesterol levels, glucose intolerance and high blood sugar levels. Poor wound healing and development of a skin rash can also be present.
