Low Ferritin Levels: Symptoms, Causes, and When to Get a Ferritin Test for Iron Deficiency

Feeling constantly tired, weak, or dizzy? You might be dealing with low ferritin levels — a silent but significant indicator of your body’s iron stores. Ferritin is a blood protein that contains iron, and having the right amount is essential for maintaining energy, oxygen circulation, and overall health. Without enough ferritin, your body can’t access the iron it needs, leading to symptoms such as persistent fatigue, shortness of breath, pale skin, headaches, brittle nails, and even heart palpitations. Whether due to heavy menstruation, chronic illness, poor diet, or issues with nutrient absorption, low ferritin can affect anyone — but the good news is, it’s easily detectable through a simple blood test. Even better, you can now take an at-home blood test, making it easier than ever to stay on top of your health. Let’s explore the symptoms of ferritin deficiency, what causes it, and when it’s time to schedule a ferritin blood test — even from the comfort of your home.

What Is Ferritin and Why Is It Important?

Ferritin is like your body’s iron savings account — it stores extra iron so your body can withdraw it when needed. While a standard iron test shows how much iron is currently in your bloodstream (your checking account), a ferritin test reveals how much you’ve got in reserve.

Here’s the catch: you can have normal iron levels but low ferritin, and still feel completely drained. Why? Because your body might be running on fumes — burning through stored iron without having enough backup. This is why so many people with low ferritin experience symptoms like fatigue that doesn’t go away, constant brain fog, hair loss, or feeling out of breath — even if basic blood tests come back “normal.”

If you’ve been feeling off but can’t quite explain why, don’t ignore it. A quick ferritin test — even with an at-home blood test — can uncover what your body’s really missing. And the sooner you catch it, the faster you can start feeling like yourself again.

Ferritin levels are typically considered low when they fall below 30 ng/mL. However, levels under 15 ng/mL are often classified as dangerously low and indicate a serious deficiency that demands immediate medical attention.

At these critically low levels, your body struggles to maintain essential functions, leading to intense symptoms such as extreme fatigue, shortness of breath, dizziness, or even fainting. You may also notice a significant decline in your physical endurance and mental clarity.

Though this article focuses on low ferritin levels, it’s important to remember that both high and low ferritin levels can indicate serious health concerns.

Whether ferritin levels are too low or too high, both situations warrant prompt medical assistance. Identifying the root cause early can lead to more effective treatment and prevent complications. If you notice symptoms of iron imbalance, don’t hesitate to seek professional advice for proper testing and diagnosis.
