Manganese is one mineral you are unlikely to have to supplement in your diet. It is involved in many enzyme reactions as it is a co-factor required by the enzyme. It is involved in removing free radicals as well as regulation of sugar release from muscle and liver tissue.
Strontium may not be required for good health, but it can help build healthy bones since it is chemically similar to calcium.
About 50% of the Magnesium in our bodies is found in bone. In the body, it has vital roles in muscle and nerve function, as well as heart rhythm, immune system and bones. It may help reduce blood pressure and may have a role in a whole host of medical problems when we are deficient, and most people probably are.
