If you're addressing an iron deficiency, this product delivers 65 mg of **Iron** per tablet — right at the top of the 15–45 mg clinical range and well above the tolerable upper limit of 45 mg for general supplementation. At this dose, you're getting a therapeutic amount typically used for deficiency correction, not daily maintenance.

The form you're getting is ferrous sulfate, which is one of the most studied iron forms and reasonably well-absorbed, but it's also the form most associated with GI side effects like constipation and nausea. More bioavailable forms like iron bisglycinate can achieve similar absorption at much lower doses with fewer stomach issues.

This is an aggressive dose that makes sense if your doctor has confirmed low iron levels. For routine supplementation or mild deficiency prevention, 65 mg of ferrous sulfate may be more than you need and harder on your stomach than necessary.
