Chromium

Sources
Found in Brewer’s yeast, black pepper, liver, wholegrains, wheatgerm, vegetables, butter, beer, molasses.

Cobalt

Sources
Green leafy vegetables, meats, brewers yeast, seafood, nuts, fruits and wholegrains.

Benefits
An essential part of vitamin B12 for the normal functioning of cells, especially red blood cells. Deficiency is associated with slow growth and goitre.

Copper

Sources
Found in brazil nuts, organ meats, dried legumes, dried stone fruits, green vegetables. Best taken with cobalt, iron and zinc.

Benefits
Helps brain development, bones, nerves and connective tissue. It is involved in many enzyme systems and essential in the production of RNA. Copper deficiency is rare and copper in excess can be toxic.

Folic Acid

Sources
B vitamin also known as folate. Found in green leafy vegetables such as spinach, watercress, silverbeet, kale and broccoli, asparagus, green beans, fortified breakfast cereals, wholegrains, oranges, meat and potatoes. Recommended supplement: 500mcg.

Needed for numerous enzyme reactions, formation of thyroxine, bone growth, fat metabolism, nerve function, and blood clotting.

Nickel

Sources
Found in soybeans, lentils, nuts, buckwheat, grains, vegetables, kelp.

Benefits
Is found in RNA and DNA and in all tissues and fluids. Deficiencies have been linked with reproductive failures and growth problems.

Phosphorus

Benefits
Is the second most abundant mineral in the body and is found in every cell. Plays a part in almost every chemical reaction in the body including metabolism of carbohydrates, proteins and fats, in muscle and nerve function, digestion, kidney function and skeletal growth.

Potassium

Sources
Wheatgerm, wholegrains, vegetables, fruits and nuts. Best taken with vitamin B6 and sodium.

Benefits
Needed to regulate blood pH and proper nerve function. Helps maintain the fluid balance in the body and is necessary for growth. A deficiency may cause headaches, water retention, irregular heartbeat, bone and joint pain, constipation, cramping, irritability and insomnia. It may be linked to poor sperm mobility. Deficiency may cause abnormality in the kidneys of the developing foetus.
