Overview

A ferrous sulfate iron tablet delivering 65 mg elemental iron per serving, positioned for cellular energy support and normal red blood cell production. Gluten free and vegetarian, 100 tablets at one serving per day.

Iron supplementation is one of the more common single-ingredient additions to a routine, and this one keeps the formula plain: ferrous sulfate delivering 65 mg elemental iron with nothing else layered in. That makes it simple to pair with other supplements without overlapping ingredients.

  • 65 mg elemental iron per tablet
  • 325 mg ferrous sulfate formula
  • Gluten free and vegetarian
  • 100 count, one tablet per day

Who it's for

Suits adults advised to raise iron intake who want a plain, gluten free ferrous sulfate tablet rather than a multivitamin with iron folded in. Not intended for children, and anyone with iron-related restrictions should check with a doctor before starting a 65 mg dose.

Performance notes

The listing frames this toward cellular energy support and normal red blood cell production, both standard associations with iron status rather than claims specific to this product.
