Eye, hair, nail, mouth and skin symptoms are among the early outward warning signs of vitamin and mineral deficiencies. The following compilations may help in diagnosing and treating these deficiencies. However, increased metabolic requirements for indicated deficiencies may persist for a long time after the outward symptoms have disappeared. Many listed symptoms may also be caused or aggravated by allergies and problems with the blood sugar and fat metabolism.

The right-hand column gives the primary deficiencies first, additional treatment or cause is given in parentheses. For each condition only the more prominent nutrients are mentioned. However, all the typical nutrients should be supplied in increased amounts in the treatment of all conditions.
