What does the evidence say about Iron Bisglycinate Fatigue Randomized Trial?

Updated October 2026

Quick Answer

Iron Bisglycinate Fatigue Randomized Trial has evidence relevant to benefits, uncertainty, and practical interpretation, but conclusions should stay close to the cited sources. One representative finding is: In a prospective cross-over stable-isotope absorption trial in young iron-deficient women (n = 52), OatNF reduced with sodium ascorbate carried mainly ferrous iron and showed high fractional absorption with water and with polyphenol-rich food, showing 1.76- and 1.65-fold higher absorption, respectively, compared with ferrous sulfate.

Key Takeaways

  • 01In a prospective cross-over stable-isotope absorption trial in young iron-deficient women (n = 52), OatNF reduced with sodium ascorbate carried mainly ferrous iron and showed high fractional absorption with water and with polyphenol-rich food, showing 1.76- and 1.65-fold higher absorption, respectively, compared with ferrous sulfate. [Zhou J (2025)]
  • 02Iron fortification can help to treat anaemia, but most current fortificants are limited by low absorption and/or poor sensory properties. [Zhou J (2025)]
  • 03Here we introduce oat protein nanofibrils (OatNF) carrying ultrasmall iron nanoparticles that are engineered to carry iron in ferrous or ferric form. [Zhou J (2025)]

Level 1 usually indicates systematic-review style evidence, level 2 indicates randomized trials or public-health guidance, and lower levels need more cautious wording. This page is educational. People with medical conditions, pregnancy, medication use, or unusual symptoms should ask a qualified clinician before changing supplements, medication, or treatment routines.
