Efficacy and Tolerability of Sucrosomial® Iron vs Ferric Maltol in Iron Deficient Women (SID-WOMEN)

March 20, 2026 updated by: Pharmanutra S.p.a.

A Prospective, Open-Label, Randomized, Interventional Study to Evaluate the Efficacy and Tolerability of Sucrosomial® Iron vs Ferric Maltol in Iron Deficient Women

This study aims to compare two oral iron treatments, Sucrosomial® Iron and Ferric Maltol, in women with mild to moderate iron deficiency anemia. Many patients experience gastrointestinal side effects or poor tolerability with traditional iron supplements, which may limit adherence. Participants will be randomly assigned to receive either Sucrosomial® Iron or Ferric Maltol for 12 weeks. The primary objective is to determine whether Sucrosomial® Iron is as effective as Ferric Maltol in normalizing hemoglobin levels.

Study Overview

Detailed Description

This prospective, randomized, open-label, two-arm study evaluates whether Sucrosomial® Iron is non-inferior to Ferric Maltol in normalizing hemoglobin levels over 12 weeks in women with mild to moderate iron deficiency anemia. A total of 146 participants will be randomized 1:1 to receive either Sucrosomial® Iron or Ferric Maltol.

The primary endpoint is hemoglobin normalization at Week 12. Secondary endpoints include changes in iron parameters (serum iron, ferritin, transferrin saturation), fatigue improvement using the FACIT-Fatigue Scale, and assessment of tolerability (adverse events, discontinuations). The study includes a screening phase and follow-up visits at Weeks 4, 6, 8, and 12 for safety monitoring, laboratory assessments, and evaluation of treatment compliance.

Arms and Interventions

Participant Group / Arm
Intervention / Treatment
Experimental: Sucrosomial® Iron

Participants will receive dietary supplement Sucrosomial® Iron (Sideral® Forte) for 12 weeks.

The dose consists of 60 mg/day of elemental iron (two capsules of Sideral® Forte per day), taken orally on an empty stomach (1 hour before or 2 hours after meals).
