How to Know If You're Iron Deficient (Without Guessing)
Feeling tired all the time? Having trouble concentrating? Catching every cold that goes around? These may sound like everyday problems, but they could be symptoms of iron deficiency, one of the most common yet underdiagnosed health concerns today.
At Intra-V, we see clients every week who've been struggling with low energy, brain fog, or unexplained fatigue, only to discover that iron was the missing link all along.
In this post, we'll explore:
What iron does for your body
Common symptoms of iron deficiency
Who's at risk
How to test your levels — and what to do next
Why Iron Matters More Than You Think
Iron is a mineral your body needs to produce hemoglobin, the protein in red blood cells that transports oxygen throughout your body. When iron levels are low, your tissues and organs don't get enough oxygen, and that affects everything from energy and focus to immunity and recovery.
Even mild iron deficiency can cause subtle but disruptive symptoms that build up over time. That's why it's important not to guess — and instead take a closer look at what your body might be telling you.
Common Symptoms of Iron Deficiency
Here are some of the most frequent signs of low iron we see in our clients at Intra-V:
Fatigue or constant low energy
Shortness of breath, especially during activity
Pale skin or dark under-eye circles
Headaches or dizziness
Cold hands and feet
Hair thinning or brittle nails
Brain fog or difficulty concentrating
Cravings for ice or non-food items (a condition called pica)
It's easy to dismiss these as part of a busy lifestyle, but if they're persistent, they could signal something deeper.
Who Is Most at Risk?
Certain groups are more likely to experience iron deficiency, including:
Women with heavy menstrual cycles
Pregnant or postpartum women
People with digestive disorders like celiac, Crohn's, or ulcerative colitis
Vegans or vegetarians (who may consume less absorbable iron)
Endurance athletes or those with high physical demands
Individuals who've had gastric bypass or weight loss surgery
People recovering from illness, surgery, or chronic inflammation
If you fall into one of these categories and have noticed symptoms, it's worth checking your iron levels.
How to Test for Iron Deficiency
The only way to know for sure if you're iron deficient is with a simple blood test. At Intra-V, we can test for:
Serum Iron – measures how much iron is in your blood
Ferritin – shows how much iron your body has stored
Total Iron Binding Capacity (TIBC) – assesses how well your blood can transport iron
Hemoglobin and Hematocrit indicate whether iron levels are affecting your red blood cells
These lab values give us a clear picture of your iron status — and help determine whether oral supplements or iron infusions are the right solution for you.
When Supplements Aren't Enough
Some people try oral iron first, but experience nausea, constipation, or poor absorption, especially if they have digestive issues. In those cases, we offer iron infusions, which deliver a precise dose of iron directly into your bloodstream for faster, more effective results — often in just a few sessions.
You'll start feeling better without the GI side effects that many people experience with over-the-counter supplements.
