Table of Contents [ Hide ]


There are multiple diseases around us and in our body of which we are simply not aware. One of them is iron deficiency. In fact, millions of people worldwide do not get enough iron to be productive throughout the day. That’s when the BEST IRON SUPPLEMENT comes to help!

There are various TYPES OF IRON SUPPLEMENTS, but not all of them are well-absorbed. If you eat a food and your body cannot absorb all of the nutrients in this food, it will be a big waste. The same thing happens when you take a poorly-absorbed iron supplement.

So, keep reading on our best absorbed iron supplement review to find out excellent products which not only work effectively but also absorb fast.

Why Should You Choose Absorbed Iron Supplement?

Anemia Treatment

Anemia occurs when the number of red cells in the blood drops too low. A person suffering from this condition would look pale and have little energy for daily activities. Anemia can be caused by a lack of other minerals and vitamins, and iron deficiency is the most common of anemia.

Fortunately, this illness can be solved by taking the right quantities of iron supplements. If done correctly as suggested by doctors, one can cure anemia after just a few days. The effects are clear and almost immediately [1].

Availability and Convenience

You can find the best absorbed iron supplement in many forms, including pills, capsules, and liquid. They are widely sold in small or big pharmacies around the world at very reasonable prices.

Additionally, many people choose to take iron supplements as a regular preventive method against iron deficiency. That’s because they find it hard to ensure iron intake via foods. If you don’t want all the fuss in disciplining yourself in diets, you can easily take regular iron supplements, but only after consulting doctors.

High Absorption Rate

Compared to lowly-absorbed iron supplements, highly-absorbed ones are more recommended for people of both genders and all ages. The reason is very simple: The more your body can absorb nutrients from what you consume, the better the result. That’s why the best iron supplement is usually the best absorbed iron supplement.

Keep in mind that highly-absorbed irons come from animal sources which are ground meats such as beef, pork, chicken, turkey, clams, etc. Organ meats, like beef or pork liver, are also great sources when it comes to iron supplement with the high absorption rate, but they are not recommended for those who suffer from high cholesterol.

Heme Iron vs. Non-Heme Iron – Which Has Better Absorption Rate?

Iron supplements have two different forms: heme iron and non-heme iron. Heme iron is bound to oxygen called hemoglobin, which circulates protein in the bloodstream. On the other hand, non-heme iron is not bound to oxygen. The following sections will show you other differences between these twos:


Heme iron can be found only in animal protein, such as meat, seafood, poultry. By contrast, non-heme iron is most commonly found in plant-based foods such as seeds, beans, nuts, fruits, grains, and vegetables. It can also be contained in eggs and dairy products. So, if you consume meat and dairy products, you get both heme and non-heme iron [2].

It’s also interesting to know that only 40% to 45% of meat iron is heme iron. Non-heme iron makes up the rest of the total iron amount. The milligrams of iron you see on your meat label means that half of it is heme and the other half is non-heme.

Absorption Rate

This characteristic of iron supplements affects the way our body absorbs iron. Heme iron is absorbed significantly more by the human body than non-heme iron. For example, when you eat chicken liver, your body takes in as much as 35% of heme iron. If your food or supplement has non-heme iron, namely ferrous sulfate or ferrous fumarate, the actual rate of absorption is only 2.9% on an empty stomach. This figure can be much lower (0.9%) if you take non-heme iron with other food composition.

As a result, if you’re looking for the best absorbed iron supplement, you should stick with heme iron products. However, if you still have the bigger interest in non-heme iron products, you should check out HOW TO TAKE IRON SUPPLEMENTS FOR BEST ABSORPTION to make sure you can get the most of iron.

Moreover, non-heme iron might have terrible side effects including diarrhea, flatulence, and nausea. However, you can be spared from these side effects if you take heme iron supplements.

It is true that heme iron is actually superior to non-heme sources, considering what we have analyzed so far. However, people use non-heme iron more frequently than heme iron. That’s because the first choice tends to be cheaper and more common, and people can take higher amounts of non-heme iron so that the overall absorption rate is equal.
