In transcript order-
Avoid taking iron supplements (or multivitamins high in iron) unless medically indicated, since excess iron accelerates aging via free-radical damage and senescent cell accumulation.
“don't take an iron supplement necessarily
CaveatsWomen may need iron at certain times of the month; people with hemochromatosis should follow doctor advice.Certaintyexplicitmild caution -
Measure blood iron levels (free and bound) to detect iron overload.
“measure their blood biochemistry and determine whether their iron... are out of whack
Certaintyexplicitrecommendation -
For people with hemochromatosis, donating blood is a standard way to reduce excess iron.
“donate blood if you can
