Overview

NOW Supplements Iron 36 mg is a double-strength, non-constipating iron formula in 90 vegetarian capsules, positioned as an essential mineral supplement free of dairy, egg, nut and soy.

The non-constipating claim addresses a common complaint with standard iron supplements, which can cause digestive discomfort at higher doses. At 36 mg, this sits at what NOW labels double strength relative to typical lower-dose iron products, aimed at people with a specific need for higher iron intake rather than general multivitamin-level coverage. The capsule is vegan, halal and kosher certified.

  • 36 mg double-strength iron per capsule
  • Non-constipating formulation
  • 90 vegetarian capsules
  • Halal, kosher and vegan certified

Who it's for

Fits people who need a higher-dose iron supplement but have had digestive issues with standard iron products in the past. Not necessary for anyone whose diet or multivitamin already covers typical iron needs, since 36 mg is a targeted, elevated dose.
