Overview
NaturesPlus Hema-Plex Iron combines 85 mg of chelated iron with vitamin C and bioflavonoids in a slow-release tablet, 30 to a bottle. It is rated 4.7 stars from about 4,000 reviews, with roughly 1,000 units bought in the past month.
Chelated iron and a slow-release tablet design are both aimed at reducing the stomach upset that plain iron salts commonly cause, and pairing iron with vitamin C is a known approach to support absorption. At 85 mg per tablet, this sits well above a typical multivitamin's iron dose, so it reads as a targeted iron supplement rather than a general multivitamin. The 30 count bottle covers a month at one tablet daily.
- 85 mg chelated iron
- Slow-release tablet
- Vitamin C and bioflavonoids added
- 30 count, vegetarian and non-GMO
Who it's for
Suited to adults who need a higher-dose iron supplement and want a formula built to be gentler on the stomach than standard ferrous sulfate. Not intended for anyone who has not confirmed with a doctor that an 85 mg dose is appropriate for their situation.
Strengths and trade-offs
Drawn from this product's published specifications.
- 85 mg chelated iron per tablet
- Slow-release formula for gentler digestion
- Vitamin C included for absorption
- Non-GMO and vegetarian
- High dose needs medical confirmation for some
- 30 count is only a one month supply
Performance notes
Slow-release tablets dissolve gradually rather than all at once, which is the mechanism behind reduced digestive side effects compared to standard iron tablets. The added vitamin C and bioflavonoids are included specifically to support iron absorption rather than as separate nutritional additions.
