Cons

- -Requires avoiding calcium-rich foods or supplements near dosing time and ideally co-administration with vitamin C — some find this inconvenient
- -Isolated reports of digestive upset, suggesting individual tolerance still varies
Best For
Watch Out
- !May not raise ferritin quickly enough for critically low iron stores — seek medical advice on dosage for therapeutic use
- !Calcium (dairy, antacids, calcium supplements) significantly blocks iron absorption — leave a 2-hour gap
- !Co-administration with vitamin C substantially improves absorption — often necessary to see meaningful results
- !Self-treating without blood test monitoring risks both under-dosing and, less commonly, excess iron accumulation
