Exploring tolerance and side effects of an innovative yeast-bound iron supplement: a feasibility trial.

ABSTRACT:

Background

Iron deficiency is prevalent among female athletes, often leading to fatigue, impaired recovery, and decreased performance. Conventional oral iron supplements are associated with poor absorption and negative gastrointestinal side effects, resulting in low adherence. This feasibility trial investigated the tolerability and gastrointestinal effects of an iron-yeast complex (FeSC) supplement in physically active females to assess its potential for further study.

Methods

This single-arm, mixed-methods feasibility trial recruited 14 active females (18-25 years) who consumed FeSC-fortified cookies (40 mg elemental iron) every other day for 14 days. Gastrointestinal symptoms, stress, and recovery were assessed through daily and weekly questionnaires (daily questionnaires
