Why testing CBC and ferritin levels matters for young female athletes’ energy and performance

A Page Dedicated to Athletes & Parents

Iron deficiency is one of the most common — and most overlooked — health issues in female athletes.

Many early signs are subtle and easy to miss. They’re often mistaken for burnout, overtraining, stress, or just “being a teenager.”

Iron deficiency can creep up slowly, quietly draining energy and performance long before anyone realizes what’s happening. Research shows it affects 15–52% of young female athletes, depending on the sport and age group.

The good news? Catching it early with a simple ferritin + CBC test can change everything.

Recognizing the warning signs and testing proactively helps young athletes stay strong, recover faster, and keep playing the sports they love — instead of fighting unexplained fatigue.

Early Common Signs of Low Iron in Female Athletes

  • Heavy, irregular, or missed menstrual periods Excessive bleeding quickly depletes iron stores—especially common in teenage athletes.

  • Mood changes, irritability, or depression-like symptoms Low iron affects brain function and can lead to anxiety, low mood, or feeling “off” emotionally.

  • Persistent fatigue and low energy Constant tiredness that doesn’t improve with rest—making practices, games, or even daily life feel exhausting.

  • Frequent illnesses or slow recovery A weakened immune system means more colds, infections, sinus issues, or longer recovery from minor bugs.

  • Pica (unusual cravings) Craving and chewing non-food items like ice—a classic (and often overlooked) sign of iron deficiency.

  • Declining performance despite consistent training Training hard but not improving—or even getting slower, weaker, or losing endurance.

These symptoms are easy to brush off as “normal” for busy, high achieving athletes—burnout, stress, puberty, or just a tough season.

But if your athlete is showing 2 or more of these signs, it’s worth testing ferritin and CBC levels. Low iron is common, treatable, and catching it early can make a huge difference in performance, health, and enjoyment of the sport.

Low Iron Steals Performance — Quietly

  • Oxygen delivery drops → endurance falls 10–20%

  • Recovery slows, weakness sets in, motivation disappears

  • Looks exactly like burnout (and often is misdiagnosed as such)

  • Female athletes lose iron fastest: periods, growth, sweat, hard training

Result: fading performance, more injuries, lost seasons.

Early ferritin + CBC testing stops this before it starts.

Advocating for the Right Test

When you visit a doctor, being specific makes a big difference. Many doctors will order a ferritin test if you clearly explain your concern. Try saying something like:

“I’m worried about iron deficiency affecting performance/energy. I’d like a ferritin test (and possibly a CBC) to check iron stores.”

You can also ask these reasonable questions:

  • Which exact tests are being ordered?

  • Will insurance cover them?

  • What will my out-of-pocket cost be if insurance doesn’t fully pay?

Insurance coverage for preventive or ferritin-only testing is often limited or denied, even when it’s medically appropriate. If that happens, out-of-pocket lab costs can easily reach $65–$150+ depending on the provider.

That’s why Iron Strong Athletes offers affordable, direct-access vouchers starting at $58 — no doctor’s order or insurance needed. You get the exact tests you want (ferritin, CBC, anemia panels, etc.) at a predictable price through a convenient local lab.

Doctors are usually fine with patients choosing a more affordable lab option — it’s your right to shop around for better value and faster access.
