Analysis
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.
Pros
- 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.
Cons
- Contains calcium carbonate, which can inhibit iron absorption.
- May require careful timing of intake to maximize iron benefits.
- Not a chelated iron form.
Warnings
- 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.

Goals
Impact
High effect
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.
Impact
High effect
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.
Impact

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.
Impact
High effect
Productivity relies on sustained energy and mental clarity, which iron supports. The inclusion of calcium may subtly hinder the full potential of the iron to provide these boosts.
