Iron helps you avoid anemia, possibly boosting your endurance by 45%
According to scientists, as an oxygen "carrier," iron is a vital mineral in your body. They claim this mineral deficiency causes a low level of hemoglobin. It leads to a severe heart disorder called anemia, which may strongly impair your daily performance. During anemia, you're low on energy, have sudden attacks of weakness, and constant tiredness, making it hard for you to focus and think clearly.
Meanwhile, iron may help maintain your muscles' function — it supplies them with the necessary oxygen to contract. At the same time, iron-related anemia can reduce your endurance by more than 45%. Therefore, taking iron supplements in some cases may help you boost energy levels.
Iron can relieve irritability, headaches and enhance your focus
Scientists claim that lack of iron in your blood can affect your cognitive performance no matter how much sleep you get or what food you eat. Iron-related anemia can disturb your focus, causes headaches, and makes you easily irritable. With sufficient iron levels in the blood, you may find it easier to perform cognitive tasks that include spatial processing or reasoning. It may happen due to the high content of oxygen in your brain, which enhances its performance.
Iron may help you sleep better and lower your risks of getting insomnia
Have troubles with falling asleep at night? Then consider adding iron to your daily supplementation! A study proves iron deficiency causes insomnia and sleep disturbances, so you may get enough sleep without medications by taking iron supplements. Meanwhile, anemia contributes to anxiety and depression symptoms, which are also related to insomnia.
What is iron?
Iron is a trace mineral vital for maintaining a decent hemoglobin level, strong immunity, and healthy growth. But our bodies fail to get all the iron from our meals — that's the most common reason why so many people (almost 25% worldwide) have iron deficiency. Low iron levels are linked to overall weakness, impaired brain performance, low immunity, and poor concentration. If you lack iron, you'll find it hard to exercise and work efficiently, face constant headaches and migraines.
