What the evidence supports: treating iron-deficiency anaemia.
This scores how well-supported the claim above is — not how much benefit you personally would get. A high score on a narrow claim does not extend to everything the product is marketed for.
How long to take it
Temporary. Typically three to six months, then retest. Stop once ferritin is comfortably in range.
Who it's actually for
Only people with a confirmed low ferritin or a clear clinical reason. Never take iron speculatively.
Safe upper limit

45 mg per day (elemental)
The body has no way to excrete excess iron. Overload damages the liver, heart, and pancreas — and haemochromatosis is common enough to matter.
