Start with fundamentals

Regular meals, adequate fluids and a varied diet help support normal body function. Individual needs differ with health conditions and medications.

Why dizziness complicates the picture

Lightheadedness may relate to dehydration or missed meals, but it may also involve blood pressure, medication effects, heart rhythm, the inner ear or neurological causes.

Supplements are not a dietary replacement

FDA advises that supplements should not replace the variety of foods important to a healthy diet or substitute for prescription treatment.

Get individualized guidance

A registered dietitian or clinician can evaluate dietary adequacy, symptoms, medical history and laboratory results rather than guessing from marketing claims.
