How good will dr.wilson's product be for mild adrenal fatigue?and how long will i have to take them?

Helpful, it depends: Dr. Wilson has several products; they all look good though i'm most impressed with the herbal adrenal support formula. But taking these alone won't cure it; adrenal fatigue is caused by chronic stress, both physical ; emotional, so a healthy diet, adequate rest, relaxation techniques ; dealing with other issues like food allergies, chronic infections ; hypothyroidism are all important components.
