Are your iron levels holding you back from optimizing your fitness?

It turns out, there's a correlation between your iron levels and your fitness levels.

Just because you’re putting in all the hours and pumping through all the reps doesn’t mean you’re getting the best possible results. Certain things can hold you back from achieving your full fitness potential, and one of them is your iron levels. While creatine and protein get all the glory, iron could really give your workouts a much-needed boost. Let’s look at the benefits of iron, how to tell if you have a deficiency, and what to do about it.

What is iron?

Iron is a key mineral that’s necessary for growth, development, and other bodily functions. It helps carry oxygen through your body because it’s a component of hemoglobin — the protein in red blood cells. Iron is involved in many processes, including:

  • Energy production
  • Muscle function
  • Your immune system
  • Bone marrow health
  • Organ function
  • The production of certain hormones

How does iron reboot your performance?

Your iron levels affect how tired and fatigued you feel every day, especially when you’re pumping iron, pun intended. If you lack this key nutrient, you might feel too tired to workout, and by the time that strength training sesh rolls around, you’re too spent to conquer it.

Since iron affects everything from your brain function and memory to your immune health, it makes sense that your workouts might suffer if you’re lacking. Iron is a mineral that’s a natural energy supplier worth considering if your workouts are feeling sluggish.

One interesting study showed that iron insufficiency can negatively impact sports performance, and that iron is necessary for energy metabolism and transporting oxygen for endurance athletes. The study revealed that iron helps athletes prevent an increased heart rate, exhaustion, and shortness of breath during exercise.

What are the signs of iron deficiency?

Here are the signs of iron deficiency to look out for:

  • Fatigue
  • Pale skin
  • Shortness of breath
  • Headaches
  • Dizziness
  • General weakness
  • Unexplained weight gain
  • Brittle nails
  • Itchy rash
  • Red or purple dots on the skin

It’s also possible to not really feel any symptoms of low iron until the deficiency becomes more severe.

You can ask a doctor to check your iron levels with a blood test. You can also get at-home ferritin tests. Ferritin is the blood protein that stores iron in your body.

How to improve your iron levels

There’s a correlation between your fitness level and your iron levels, so it’s worth paying attention to. If you know you’re probably not consuming enough iron-rich natural foods in your diet, that’s the first place to start before considering iron supplements. Foods high in iron include:

Adding vitamin C-rich foods like cherries, red and yellow peppers, and broccoli can help you better absorb iron. Most fitness professionals recommend taking iron supplements when needed and trying to boost iron consumption in your diet. 

Taking iron when you’re not deficient can be problematic, so if you’re concerned about your diet or iron levels, it’s always best to consult with your healthcare provider. Some people have low iron levels due to malabsorption in the gut, bowel conditions, and other medical reasons.

Get the “Extraction” body before Chris Hemsworth’s threequel
Extraction Workout

Movies lied to me when I was a kid. When I joined the Army, I had dreams of being an Army Ranger. Too many movies made me think I could be a special operator and maybe even get myself a great nickname like the GI Joes. Instead, I told one of the sergeants of my aspirations, and he flat out said I wouldn’t make it. Not that I couldn’t do it, but that they wouldn’t let me. I was too big. 6’5″ and 220 pounds was going to require too many calories. You see, Arnold Schwarzenegger, Sylvester Stallone, and Dwayne Johnson made me think that the elite soldiers needed to be hulking giants. Or world-class martial artists like Bruce Lee, Chuck Norris, or Jean-Claude Van Damme. And since I couldn’t do a roundhouse, I decided to follow the more practical path of the everyman like Bruce Willis, Nic Cage, and Tom Cruise.

You see, special operators need to be agile. They need mobility. That is why Chris Hemsworth adopted a workout with that goal to prepare for his third turn as Tyler Rake in his new Netflix film, Extraction 3.

Ditching the boring golf gear: Travis Mathew and Liberty London collaborate to bring personality to the course
Chair, Furniture, Person

I remember watching golf when I was a kid; everyone, and I mean everyone, looked the same. There are rules on a golf course. A collared shirt, no denim, a very specific look is what they go for. It is tradition, and tradition is hard to argue with. Then came Tiger Woods and John Daly. Tiger found a way to make this boring tradition a uniform. You could see the red Nike polo and black pants and knew exactly who it was. Daly? Well, he went the other way and patterns became a wild calling card. Travis Mathew and Liberty London found a way to mix both of these concepts to bring a bold new look to the game of golf.

What makes this collaboration particularly exciting is seeing Liberty’s heritage designs and colour language brought into the world of golf in such a fresh way. The striking print combinations, considered handfeel, and balance of high-performance golfwear with relaxed lifestyle pieces create a collaboration that feels both unexpected and distinctly Liberty. – Pere Bruach, Design Manager at Liberty London
