2025's Top 8 Iron Supplements
Find out what to look for in a quality Iron supplement and what to watch out for
What is Iron?
Tell me if this sounds familiar: You wake up after a good night’s sleep feeling rested and ready to take on the day, but by lunchtime you’re already feeling fatigued. It’s difficult to concentrate, and you just wish you could take a nap.
Unbeknownst to you, the solution to your midday fatigue probably isn’t more sleep. You might just be low on iron.
Are You Low on Iron?
Iron deficiency can be caused by factors such as poor diet, poor nutrient absorption, and blood loss from menstruation.
Iron deficiency is most often associated with the following symptoms:
- Weakness
- Fatigue
- Difficulty concentrating
- Impaired cognitive function
Benefits of Iron
Have you ever noticed yourself getting lightheaded or losing energy at high elevation? Maybe you were on a hike or skiing, or maybe you just flew into Denver to visit family for Christmas. These effects are caused by the reduced oxygen in the air, and it’s very similar to what happens when you don’t get enough iron.
Without iron, your body struggles to deliver oxygen from your lungs to the rest of your body. You can eat all the carbohydrates you want, drink energy drinks, or exercise, but you’re still going to feel fatigued if your muscles can’t get the oxygen they need.
Especially Important For Women
Iron is especially important for women. During menstruation, a woman’s iron reserves are depleted and must be restored. In fact, the iron loss from menstruation alone doubles a woman’s need to absorb iron in comparison to men.
Pregnancy also increases iron requirements for women and so does lactation. Factor in the fact that women’s diets tend to feature less iron than men, and you’ve got a recipe for iron deficiency.
