Pumping Iron (in your blood)

Feeling a little sluggish? You might need some more iron.

That’s because iron makes hemoglobin, a protein in red blood cells used to transport oxygen from the lungs. Low iron can leave you feeling tired or with brain fog - because you’re running low on O2.

Not only that - iron also supports our immune function to fight off infections and manages hormone levels.

Reports show that 10 million people in the U.S. and over 1 billion globally are iron-deficient. But this is probably an underestimate because we start borrowing iron stored in our muscles before test results will be outside the “normal” range.

Those most susceptible to iron deficiency are:

  • Teens - need extra iron to support normal growth and development

  • Vegetarians - the best iron sources are found in meat and animal products

  • Pre-menopausal Women - blood loss from your period can really reduce iron levels*

*Up to 50% of all women can be iron deficient, while the number is probably closer for 8-10% of men.

Iron deficiency can lead to anemia - where you simply don’t have enough hemoglobin. You absolutely cannot be thriving without red blood cells and oxygen sufficiently supporting your entire body.

Preventing Deficiency

Our bodies don’t make iron - it’s a natural occurring mineral - so we have to get it from the food we eat.

Going back to men vs.women - men only need about 8-10 mg of iron per day to replace what’s lost from normal iron utilization.

Women, on the other hand, need 20+ mg of iron daily because of the additional blood loss.

Now there are two kinds of iron - heme and non-heme. Heme comes from animal sources, while non-heme iron is found in plants.

  • Heme sources of iron are much more easily absorbed (15-35%).

  • Non-heme sources, on the other hand, like lentils are high in iron, but only 2% gets absorbed.

One way to help with absorption is to add Vitamin C-rich foods when you consume iron.

Vitamin C makes your gut more acidic (it’s literally citric acid). This acidity helps absorb iron. (List of Top Vitamin C foods)

Maybe we’re deficient because who wants to eat kiwi with oysters or oranges with beef liver??

Here’s 21 recipes to boost your iron.

It should be noted that it is possible to also have iron overload. This is mostly from genetics or too many iron supplements. If this happens iron gets stored in organs (like the liver) and damages them.

Measuring your Iron

Unfortunately, it’s not as simple as just measuring your iron levels.

My wife when I explain iron biomarkers

I promise this is worth knowing. Here are the four biomarkers to request for your lab panel…

Iron - this measure will tell you the amount of serum iron in your blood plasma. This is important to note for sure and should be tracked on your annual lab tests:

Men 

  • Standard Range = 50-150 mg/dL

  • Optimal Range = 85-130 mg/dL

Women

  • Standard Range = 35-145 mg/dL

  • Optimal Range = 75-125 mg/dL

Ferritin - this is arguably an even more important biomarker to assess iron levels. This is a protein that stores iron - mostly in muscles and the liver. It indicates the amount of iron in our reserves. We need to keep enough iron on hand at all times and this is the best indicator.

Make sure to request this as a part of your blood panel:

Men 

  • Standard Range = 25-350 mg/dL

  • Optimal Range = 45-100 mg/dL

Women

  • Standard Range = 15-300 mg/dL

  • Optimal Range = 45-100 mg/dL

There’s two more biomarkers to help give the full picture of what’s really going on.

What’s crazy is that even though iron is essential - it’s also toxic. It doesn’t go in our blood flying solo. It hitches a ride on a protein - transferrin.

Total Iron Binding Capacity (TIBC) is the blood’s capacity to bind iron with transferrin. High TIBC may indicate deficiency, while low TIBC might mean iron overload.

Here are the target results:

Men

  • Optimal Range = 250-350 µg/dL

Women

  • Optimal Range = 250-425 µg/dL

The last one (I promise) is Transferrin Saturation.

This measures the percentage of transferring proteins actually carrying iron. It’s a key result because ferritin is known to rise if the body has inflammation - regardless of iron levels. So this is a good way to double check iron levels.

Men and Women

  • Optimal Range = 24-35%
