Female Cross-Country Runner Requesting Iron and Creatine
A 20-year-old female Division I cross-country runner comes to you asking about iron and creatine. She has had two tibial stress fractures in 14 months, a BMI of 18.2, and reports 5–6 hours of sleep, restricted eating, and no menstrual period for 8 months. Her ferritin is 18 ng/mL and hemoglobin is normal. She wants to start 65 mg elemental iron twice daily and 5 g creatine monohydrate daily because a teammate improved. The coach says supplements are "part of the program" and asks you to hand out creatine to the whole distance group. She trains 70 miles per week and has a 5,000 m race in 10 days. You are the CSCS, not her physician or dietitian, and your state's scope-of-practice rules limit nutrition counseling.
1. What is your immediate response to the runner's request, and which findings require referral rather than supplement advice?

The request cannot be handled as a supplement question alone. Two stress fractures in 14 months, BMI 18.2, restricted eating, 5–6 hours of sleep, and 8 months without menses form a cluster that suggests low energy availability and possible relative energy deficiency in sport. That is outside the CSCS scope to diagnose or treat. The ferritin of 18 ng/mL with normal hemoglobin may warrant evaluation, but iron dosing should be directed by a physician because iron overload and gastrointestinal effects are real risks, and the cause of low ferritin matters. Refer her promptly to the team physician and a registered dietitian with sports specialization, and notify the athletic trainer with her knowledge. Do not tell her to start 65 mg twice daily. Do not frame creatine as a fix for low energy availability. Explain that her race in 10 days does not justify a new supplement protocol started without medical review, and that sleep and energy intake are the higher-yield issues.
2. How would you evaluate the creatine request and the coach's request to distribute creatine to the whole distance group?
Read the worked answer
Creatine monohydrate has evidence for some performance and recovery outcomes, but the decision must be individualized. For this runner, the priority is medical and dietitian review of low energy availability, not adding a supplement to a restricted intake. If the physician and dietitian approve, use a third-party-tested product, confirm hydration and usual dietary intake, and start at 3-5 g per day without a loading phase. Do not promise a 10-day race benefit; the evidence does not support an acute fix. The coach's request to distribute creatine to the whole team is a separate problem: it is not appropriate for a strength coach to hand out supplements to athletes without medical screening, informed consent, product verification, and compliance approval. Institutional and NCAA rules may restrict what can be provided and by whom. Decline the team-wide distribution, explain the liability and scope issues, and route any team education through the sports medicine and compliance staff.
3. What would you document and communicate to the coach, and what would you do if the coach continues to pressure the athlete to take supplements?
Read the worked answer
Document the athlete's reported symptoms, the referral to the physician and dietitian, the supplement requests, and your response. Keep confidential health details out of group settings. Communicate to the coach only the operational points: the athlete is being evaluated, no supplement will be distributed by you, and training load may need adjustment pending medical input. If the coach continues to pressure the athlete, escalate to the athletic trainer, team physician, and sport administrator, and follow the institution's athlete welfare policy. Do not disclose the specific menstrual or eating information to the coach without the athlete's consent; describe the concern in general terms. Offer a coach education meeting on low energy availability and supplement policy. Your role is to protect the athlete's health and stay within scope, not to win the argument with the coach. A written record protects the athlete and clarifies that supplement decisions were referred appropriately.
