If you feel weary, tired, suffer from anemia, and the color of your hair is beginning to turn grey too early, you should visit the doctor to measure the copper level in your blood.
Low copper levels affect the production of melanin, a pigment that regulates the color of hair.
Copper (about 1.2 mg of daily intake recommended for adults), a microelement for an organism, can be taken from nuts, mollusks, and entrails.
Copper plays an important role in energy metabolism, collagen synthesis, and iron absorption.
