Iron is an integral mineral for our health. It helps the transference of energy from other nutrients and plays a role in distributing oxygen throughout the body. It's available in a variety of foods, including red meat, legumes, and dark, leafy greens like spinach. Most folks who follow a well-balanced diet will get all the iron they need from food. However, some, including those with iron deficiency anemia, may need to boost their iron intake with supplements.
It's wise to consult a medical professional before turning to iron supplements. The Food and Nutrition Board (FNB) has established a daily upper limit of 45 milligrams of iron through supplementation. Exceeding that amount, particularly without medical supervision, could come with negative side effects. If you do opt to turn to iron supplements, it's important to distinguish between the many options available on the market.
