Frequent lightheadedness can be linked to low iron or B12 (anaemia); checking ferritin and B12 is sensible, though many causes are not nutritional.

Anaemia from low iron or B12 reduces oxygen delivery and commonly causes lightheadedness, especially on standing, so those are worth measuring. That said, dehydration, blood-pressure changes, inner-ear problems, and medications are frequent non-nutritional causes.
