Overview
NOW Foods Iron 18 mg is a non-constipating iron supplement in vegetarian capsule form, sold in a 120-count bottle. It's formulated as a general mineral supplement for nutritional support and carries halal, kosher and vegan certifications.
Iron supplements are notorious for causing constipation, and this formula's main claim is addressing that specifically rather than just delivering a standard iron dose. At 18mg per capsule it sits at a moderate dose. NOW markets this as an essential mineral on its own rather than pairing it with vitamin C or other absorption aids, so it stays a single-ingredient product.
- 18mg iron per vegetarian capsule
- 120-count bottle
- Non-constipating formulation
- Halal, kosher and vegan
Who it's for
Useful for adults who need a plain iron supplement and have had constipation issues with other iron products before. It won't suit anyone who wants iron combined with vitamin C or folate in the same capsule, or who needs a higher therapeutic dose than 18mg.
Strengths and trade-offs
Drawn from this product's published specifications.
- Marketed specifically as non-constipating
- 18mg moderate iron dose
- Halal, kosher and vegan certified
- Dairy, egg, nut and soy free
- Single-ingredient, no vitamin C or folate included
- 120 capsules only, no smaller trial size listed
Performance notes
The non-constipating claim points to the iron form used rather than dosage, since 18mg is a moderate amount compared with prescription-strength iron products. Being halal, kosher and vegan certified broadens who can take it without dietary conflicts.
