Study summary

Female endurance athletes are susceptible to iron deficiency and this can impact their exercise performance. This study is a pilot trial to assess the tolerability of a novel iron supplement prior to conducting a clinical trial on the efficacy of the developed novel iron supplement on iron status and performance.

Read the detailed description

Current iron supplements on the market are commonly associated with side effects including gastrointestinal distress, nausea, vomiting, and constipation. As a solution, the investigators have developed a novel delivery system for iron supplementation that overcomes many of these limitations. The goal of this study is to assess the tolerability of the developed supplement and any associated symptoms before conducting a clinical trial on this product. Participants will consume 40mg of elemental iron every second day for 14 days. Participants will complete a daily survey in which they will report feelings of stress and recovery as well as gastrointestinal symptoms. Additionally, participants will complete a more thorough survey of gastrointestinal symptoms at baseline, the mid-point, and the end of the study.

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • cis-gendered female 18-25years old
  • \<25 kg/m2
  • engaging in moderate to vigorous physical activity for ≥3 hours per week

Exclusion criteria

Exclusion Criteria:

  • gastrointestinal issues (e.g. Irritable bowel disease/syndrome)
  • chronic illnesses
  • prescription medication (including oral )
  • allergies to supplement ingredients
  • iron supplementation in the last 3 months
Terms in these criteria, in plain language(2)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

BMI (body mass index)

Weight in kilograms divided by height in metres squared. Example: 70 kg and 1.75 m gives 70 ÷ (1.75 × 1.75) ≈ 22.9.

What counts as overweight or obesity differs between countries (some use lower cut-offs), so go by the range the study states.

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.
