Shopping guide

To buy an iron supplement you have to be sure that you need it; then you must take all the precautions required to be able to buy a product that is right for you. In addition to the specifications of your doctor, it is advisable to take into account certain relevant characteristics such as those mentioned below.

iron type

When making a guide to buying the best iron supplement, several important things should be kept in mind. Acquiring one of these products and starting to consume it does not mean buying the one you like the most and that’s it; It is necessary that this is suitable for you and that it adapts to your requirements. In addition to that, a doctor should be the one to recommend the ideal supplements for you.

It is necessary that you verify the indications of the supplements to see exactly what type of iron is the main one, because this way you will have less constipation and stomach irritation.

The most common supplements use ferrous fumarate and ferrous sulfate; however, these forms of iron are the most difficult to absorb and, for that reason, will likely affect the digestive system while in use.

On the other hand, chelate and bisglycinate irons are easier to assimilate and, thanks to this, less waste will lodge in the colon, which minimizes the risk of adverse effects. In turn, iron bisglycinate has also been recognized as the element that offers the most lasting results in long-term iron levels.

Remember that it is also possible to obtain compound supplements and, in these cases, it is recommended to give a higher value to the highest percentage of the composition.

With this in mind, it’s best to look at the type of iron in the formula you’ve chosen before worrying about how much the product costs. A higher investment will give you better results.


Iron supplements do not necessarily have to be composed exclusively of this element, since the body also requires different vitamins and you could benefit from acquiring an economic complex that brings more ingredients that complement iron.

The most common element that is usually added to these supplements is vitamin C. The reason why this is so is because of the absorbent quality that the vitamin gives your body, allowing you to assimilate more iron. In addition to this vitamin, there are others that are also added, on certain occasions, among them the most prominent are B and B-12.

Those more complete supplements also usually include biotin and magnesium. This helps improve the immune system and promote collagen production, thus giving you a more comprehensive care that includes greater benefits for your body.

As for pregnant women, there are also supplements manufactured for their specific cases. These, in addition to offering the qualities of iron, are enhanced with folic acid to provide well-being to the baby and ensure its correct formation. Obviously, this must be consumed under the order of a professional.

Meanwhile, older people will also be able to consume supplements with calcium as an additional component. This strengthens the bones, which is often imperative after a certain age.

The last two alternatives tend to have higher prices, but this is because they are specialized products.


Like all products on the market, especially medicinal and multivitamin complexes, there are various options, each one presented in a different way. You will be able to notice this more easily when making a comparison of iron supplements.

The easiest thing to visualize is that the products vary in quantity. Most complexes come with approximately 100 tablets; however, it is possible to find some alternatives that offer up to 200 capsules or more. You may think that the best option is the one with the largest number of units, however, remember that the important thing is the concentration of content that each of the tablets has.

The capsules that are considered “high dose” range from 20 to 30 mg, but the most common are between 10 and 16 mg. The latter are suitable if large doses are not needed, but if required, then it is better to buy supplements with fewer capsules and higher concentration of iron.


Not all of us have the same diet, either for ethics or for health; Because of this, if you want an iron supplement you should purchase one that suits your dietary requirements.

Most of the products available are vegan, however be sure to check to make sure this is the case.

On the other hand, if you have a gluten allergy, then make sure the formula is gluten-free. Do the same if you suspect you are allergic to any other ingredient that may be in the composition.

If a doctor has diagnosed iron deficiency and it is necessary to take a supplement or follow a dietary routine, then that is when you can take this product.

Q5: Why does the iron supplement cause constipation?

Iron, due to its composition, is an element that is usually difficult for the body to absorb. Any element that is not absorbed then passes into the large intestine.

To regulate the environment of the intestine, the colon contains healthy bacteria that help with bowel movement. When there is constipation, it means that the non-beneficial bacteria have proliferated and now outnumber the good ones.

One of the characteristics of iron is that it is an element that can feed bacteria and, for that reason, it is not recommended to consume it when there are infections.

The percentage of iron in the supplement that is not absorbed will proceed to lodge in the intestine and will cause a proportional imbalance between the bacteria; this will cause constipation.

Q6: What foods should not be mixed with an iron supplement?

Changes in diet should be subject to medical advice only, however, there are some foods that should not be eaten so that they do not interfere with iron absorption.

For this reason, if you find yourself taking iron supplements, it is not recommended to eat foods rich in fiber, dairy products, cereals, caffeine, theine, cocoa, among others.

Q7: Why do stools change color when taking an iron supplement?

One of the effects caused by the intake of iron supplements is the darkening of the stool, however, this is not a bad thing, on the contrary, it is a normal process of the body.

The body, as a rule, does not absorb the full amount of iron and must eliminate the excess through the feces. Due to this, these tend to take on a black or greenish color during the time the complex is consumed.

If the stool remains dark after a while or if it takes on a tar-like hue, it is recommended to see a doctor.
