Be careful with accepting the ranges of "normal".
A lot of tests will say you are in the normal range but when you look at the actual numbers you are 16 in a range of 15-350. Literally my wife's iron level that the doctors say is in the normal range technically but it is no where close to optimal. Many tests have been changed over the last decade or 2. Widening or reducing the ranges. Look into each test to figure optimal levels and strive for that not just "normal".
