Overview
Falling ill often and feeling drained is a common reason people seek help. It is usually a signal from several systems at once rather than a single deficiency.
Sleep, nutrition, blood sugar, thyroid function and iron levels are the usual places to look first. Basic blood tests answer most of the question.
