Iron supplements are commonly used to treat iron deficiency anemia. Despite their advantages, they may cause undesirable side effects, including constipation, stomach cramps, and nausea. Hence, it is essential for those in need of increasing their iron levels to locate a supplement that they can easily endure.
When looking for the best tolerated iron supplement, it is important to consider the type of iron used in the supplement. There are two types of iron: heme and non-heme. Heme iron is found in animal products and is more easily absorbed by the body. Non-heme iron is found in plant-based sources and is not as easily absorbed. Supplements that contain heme iron may be a better option for those who struggle to absorb non-heme iron.
Another factor to consider is the form of the iron supplement. Iron supplements come in various forms, including tablets, capsules, and liquids. Tablets and capsules may be easier to take for some people, while others may prefer liquid supplements.
We spent several hours researching and testing various iron supplements to identify the best tolerated option. Our goal was to find a supplement that was effective in increasing iron levels without causing unpleasant side effects.
