Depletions
Carnitine (L-Carnitine)

Although carnitine is made by the body, deficiency can occur and may be associated with anemia, fatigue, increased blood levels of ammonia, lethargy, unexplained stupor, and heart irregularities.


Copper

Although copper deficiency is rare, signs and symptoms of long-term depletion of copper include anemia, changes in the structure and appearance of hair, heart damage, growth retardation, impaired bone formation, osteoporosis (bone loss), and emphysema (lung disease).


Selenium

Selenium deficiency may be associated with muscular, digestive, and heart disorders; long-term deficiency may be associated with increased risk of developing certain chronic illnesses such as cancer, diabetes, or liver disease.


Vitamin B9 (Folic Acid)

Low levels of folic acid have been linked to anemia, heart disease, and birth defects.


Zinc

Signs and symptoms of zinc deficiency include loss of appetite or sense of taste, growth retardation, skin changes, and increased susceptibility to infection.
