Feosol Original FAQs

What is the type of iron in Feosol Original?

The type of iron in Feosol Original iron tablets is a form of iron called ferrous sulfate. Ferrous sulfate is a non-heme iron which means it is not sourced from an animal or protein. Ferrous sulfate is a traditional form of iron that has been recommended by doctors for decades, making it the most widely used source of iron.

Feosol has been a leader in iron supplements for more than 70 years, and Feosol Original has been a leading choice among iron supplements for its ease-of-use and value.

How much elemental iron does Feosol Original contain?

Each tablet of Feosol® Original with ferrous sulfate contains 65 mg of elemental iron.

Elemental iron is simply the amount of iron available for absorption by your body. Not all irons are 100% absorbable. For example, ferrous sulfate is an iron salt, and it is 20% elemental iron. That means only 20% of the iron present is available for absorption. Though that may not seem like very much, rest assured each Feosol tablet delivers 360% of the recommended daily value for iron!

Too much math? Don’t worry. Just follow the dosage instructions on the package unless your doctor gives you other instructions.

What are the most common side effects of taking ferrous sulfate iron?

Feosol Original contains a form of iron called ferrous sulfate which may produce side effects such as constipation, diarrhea, stomach cramps or upset stomach. One more iron side effect is dark or black stool. Do not be alarmed if taking iron causes your stools to turn black; this is a typical side effect due to unabsorbed iron in the intestines.

If you are experiencing any of these effects and they persist or worsen, contact your doctor or pharmacist. In some cases, people may experience local throat pain and heartburn due to possible contact irritation from the iron.

In addition to Feosol Original with ferrous sulfate, Feosol offers a gentler iron option: Feosol Complete, a dual-iron formula that maximizes iron absorption while minimizing side effects.

I have trouble swallowing pills. Can I crush Feosol Original iron tablets for easier swallowing?

Yes, if you have problems swallowing pills and vitamins, you may crush Feosol tablets for easy swallowing. There is no functional coating on the tablets, therefore it does not enhance or impede the absorption of the iron tablet when you crush it.

Is the iron in Feosol Original a heme iron or non-heme iron?

The iron in Feosol Original is ferrous sulfate, a non-heme iron. There are two different forms of dietary iron: heme iron and non-heme iron.

Heme is a natural form of iron derived from animal sources, like the kind of iron you would find in steak, poultry or pork. Non-heme iron can be an iron salt or plant-derived, like the iron in spinach.

Delivers exactly what it advertises!

I have had difficulty finding an iron supplement that my body absorbs and I’m so grateful that I found this. Furthermore, I have not had any abdominal discomfort, nausea, or other symptoms that usually come with iron. I will be sticking with this for some time.

Feel so much better

Seems to be working...

I haven't had new labs done yet, but I know it's definitely working because I feel WAY better than I did before I started taking them. So something's happening lol. I didn't go into this expecting ambrosia as far as taste goes, but it's not bad like I thought it was going to be. Definitely doable. Pill size is great, and this is coming from someone who hates pills. I'll definitely keep buying this.
