Iron is one of the most essential minerals for our health. It plays a critical role in carrying oxygen throughout the body, supporting energy production, and maintaining healthy immune and cognitive function. Yet iron deficiency remains one of the most common nutritional deficiencies worldwide, especially among women.
Common Symptoms of Iron Deficiency
Some signs can be subtle, while others are more obvious:
- Fatigue or low energy
- Hair loss or thinning
- Brain fog
- Dizziness
- Shortness of breath with exertion
- Cold hands and feet
- Restless legs at night
Testing for Iron Deficiency
It’s very easy to test for iron deficiency with blood labs. Ask your doctor about measuring your Ferritin level, the body’s iron storage protein. You should also have a Complete Blood Count assessed which will determine if you are anemic due to low iron.
Identifying the cause of Iron deficiency
Identifying iron deficiency with labs is only the first step. It’s important to understand the root cause of low iron. Common causes of iron deficiency include:
- Heavy menstrual bleeding
- Chronic digestive issues
- Heavy Exercise
- Vegetarian or Vegan diet
Treating Iron Deficiency
The right approach depends on your individual needs, but some key strategies include:
- Food sources:
- Heme iron (best absorbed): red meat, poultry, fish
- Non-heme iron (plant-based): beans, lentils, tofu, spinach, pumpkin seeds, quinoa
- Enhance absorption: Pair plant-based iron with vitamin C–rich foods (citrus, bell peppers, strawberries).
- Avoid inhibitors: Tea, coffee, and calcium can reduce absorption if consumed with iron-rich meals.
- Supplements: Sometimes necessary, but should be taken under medical guidance, as too much iron can be harmful.
- Iron infusions: the quickest way to bring your iron up quickly is with an IV Iron infusion.
- Treat the Root Cause: Whether it is due to low intake, digestive issues, or heavy menstrual bleeding, treatment will be most effective when you understand the cause of low iron and treat it.
Takeaway: Iron deficiency is common, but it’s not something to ignore. With the right testing, diet, and support, it’s possible to restore healthy levels and feel your best again.
