Recruiting Females to Join Our Study!
We are recruiting healthy female endurance athletes ages 18–45 to participate in an 8-week research study examining iron status and exercise performance. This study will evaluate the impact of adding lactoferrin to a low dose of iron supplementation on iron homeostasis, exercise performance, and lactate metabolism in healthy, exercising women with low ferritin levels.
What’s Involved?
• 6 total visits over ~8 weeks (1 screening + 5 testing visits) and daily supplementation
o Visit 1: Consent and screening (~45 minutes)
o Visit 2, 4, and 6 (~2 hours each): Venous blood sample, questionnaires (gastrointestinal symptoms, menstrual symptoms, quality of life, training readiness/recovery), maximal aerobic treadmill test, and time-to-exhaustion treadmill test
o Visits 3 and 5 (~30–45 minutes each): Blood draw and questionnaires
• Daily supplementation for 8 weeks (one of the following):
o 100 mg lactoferrin + 5 mg iron
o 300 mg lactoferrin + 5 mg iron
o Placebo + 5 mg iron
• $500 Compensation
