An affordable tablet offering 27 mg of ferrous gluconate iron, but its accompanying calcium may reduce iron absorption.

insightsAnalysis

The 21st Century Iron supplement provides 27 mg of iron as ferrous gluconate, a form often considered to be somewhat gentler on the stomach than ferrous sulfate. It also includes 110 mg of calcium from calcium carbonate.

While the iron dose is appropriate for many individuals seeking daily support, the presence of calcium carbonate can interfere with iron absorption if taken together. This makes careful timing of intake important for maximizing the iron's effectiveness.

thumb_upPros
  • Provides a moderate 27 mg dose of iron.
  • Uses ferrous gluconate, which can be gentler than some other iron forms.
  • Extremely low price at $0.04 per serving.
  • Convenient tablet form.
thumb_downCons
  • Contains calcium carbonate, which can inhibit iron absorption.
  • May require careful timing of intake to maximize iron benefits.
  • Not a chelated iron form.
warningWarnings
  • To optimize iron absorption, consider taking this supplement at a different time than calcium-rich foods or supplements.
  • Iron supplements can cause digestive upset or constipation.
  • Keep out of reach of children due to risk of accidental iron overdose.

Categories

Iron 68
This product provides a solid iron dose, but the concurrent inclusion of calcium means it's not an ideal standalone iron supplement for maximum absorption. Users need to be mindful of this interaction.

Goals

flag Energy 70
Iron is crucial for energy, and 27 mg is a good dose. However, the calcium inclusion might slightly reduce the iron's overall contribution to energy levels if not timed correctly for absorption.
flag Fitness 69
For fitness, optimal oxygen transport is key, which iron supports. The potential for reduced absorption due to calcium could mean a slightly less effective contribution to fitness goals compared to a pure iron product.
flag Mental Focus 69
While iron supports cognitive function, the calcium's potential to interfere with iron uptake means that the benefits to mental focus might be somewhat diminished unless absorption is managed.
