Criteria Used for Evaluation

Use

If you have been diagnosed with an iron deficiency absolutely look at your diet first. However, you will most likely need an iron supplement to ensure you get the right amount your body needs.

We here at RunnerClick want to help all of our runner friends be as healthy as they can and get the most enjoyment and the best results they can from their runs and workouts. That is why when we decided to review iron supplements, we wanted to be sure to look at how easy they are to use and who they are intended for.

We made sure the products we include on our guide were designed and formulated to be usable for a wide range of people and to be applicable to many different situations and scenarios. If you have been diagnosed with an iron deficiency absolutely look at your diet first. Meats and seafood are terrific sources of iron and they absorb very in the body.

You can try fortified cereals, leafy greens are particularly high in iron as well as dark chocolate, legumes, and tofu. Try to eat as many of these foods as possible in every meal and that should help you with your deficiency. If you are still in need of supplementation in addition to your iron-rich diet this list gives you a comprehensive review of the best over-the-counter options.

Remember to include vitamin C both when you are eating iron-rich foods and when you are taking the supplementation to help with absorption. Remember that coffee and tea, and even calcium supplements can impede your body’s ability to absorb iron. Therefore it is best to try to take your iron supplement as far apart as possible from any ingestion of tea , coffee, and calcium supplement.

Compatibility

Unfortunately, oral iron supplements can come with very undesirable gastrointestinal problems if not taken properly. Before you buy an iron supplement, make sure you take a look at your specific needs and preferences to ensure it will work for you.

When it comes to any type of supplement it is important to think about how it will react to other medications and supplements and vitamins you may be taking already. Some prescriptions can interact with OTC medications and supplements and vice verso so it is important that you talk to your health care provider about anything you are taking and any health concerns you may have.

They can work with you to ensure you are no putting yourself at risk for side effects or complications with a particular iron supplement. You may experience nausea, vomiting, diarrhea or constipation, indigestion, and get what many call the “burp factor.” Normally these are because of dosing and while you continue your regimen you should see a lessening in these side effects.

If you gradually start with small doses and work up to your larger dose you may be able to increase your body’s ability to tolerate the iron and that could help you with digesting it to avoid or decrease the side effects. Eating when you take your medication can help ease the symptoms the iron causes, but it also decreases the amount of the iron you are going to be able to absorb so that is certainly a consideration.

Application

Iron can come in tablets, capsules, chewable, melt in your mouth, or be liquid form. We know some of you may be pickier than others, so make sure to choose the option you won't mind taking on a daily basis.

With all of the different types and formulations and strengths available to choose from with irons supplements, we wanted to help make your choice easier. To this end, we tried to present a range of products that represented a varied selection of what is available on the market today.

Everyone is different and different people need different supplements, even of the same element- like iron. The way you apply a supplement can have a big impact on how successful it is and we wanted to make sure this aspect of selection was included in our search criteria. You have many different options to take iron.

Some iron supplements are formulated to be slow-release and these can be taken once daily and release the iron throughout the body throughout the day. Tablets tend to be the most affordable option and they also tend to be better absorbed in the body. Liquids can be a terrific option for children as this is a preferred way for children to safely take the supplement.

Tablets and capsules can be choking hazards and also super difficult for many small ones to physically be able to swallow in general. Supplements that are formulated to be slow-release generally have far fewer side effects. This is because the amount of the supplement your body ingests is just a little quantity at a time.

The big thing to remember with a slow-release is that you want to take them as is and not grind or pour out the contents of the pill because that could lead to greater side effects and toxicity. Your personal preference comes into account. Some people have a hard time swallowing one big pill, so they’d prefer more pills that are smaller.

They may also consider pills that melt in your mouth so swallowing isn’t an issue at all. Liquids can be sticky, and some can be made with dyes that have the ability to stain your teeth. If you want to avoid this issue just make sure you are getting the solid pill or tablet iron supplement options--we have plenty of them on our list.

Ease of Use

You must carefully consider what supplements are right for you. You should get something that is easy for you to take and never a hassle--so it will never be a problem to take it daily.

Gastrointestinal side effects are the chief problem with iron supplements. Those supplements that use ferrous salts, which would be ferrous sulfate, ferrous gluconate, and ferrous fumarate are very much inferior to those that use polysaccharides- which are an iron complex form. Ferrous gluconate is 12% elemental iron, while ferrous sulfate is 20% and finally ferrous fumarate is 33%.

Ferrous salts have a much lower rate of assimilation and because they have low elemental iron levels you have to take more in dose or a number of pills each day. When you take in ferrous salts, they release in the stomach. This will cause an extreme amount of discomfort and side symptoms such as diarrhea and constipation, even pain in the stomach.

We here at RunnerClick know how annoying side effects can be, so we did our best to find iron supplements that rated low for side effects and negative drawbacks. We closely examined user reviews and feedback to find products that were safe and effective and easy to use. From stomach upset to bad aftertaste we wanted to present to you products that you could actually enjoy using rather than dreading.

We know it is important than your vitamins and supplements be easy to use and we wanted to take care of that for you with this review. At the end of the day, you need to make sure you are putting your needs and preferences at the forefront--so make sure you get something you know will be easy for you to take daily.

Effectiveness

You will have your pick of oral iron supplements that are available in many different preparations for oral consumption.

Most common, are ferrous salts and polysaccharide irons. Within every dose and every tablet or capsule, there will be different volumes of iron, and every type of iron has varying amounts of elemental iron. Elemental iron is the complete measure of iron in the supplement that is accessible for your body’s absorption. ferrous salts almost always cause an aftertaste while polysaccharides do not.

Ferrous salts actually have the ability to stain your teeth, were as you won’t’ have to worry about that with polysaccharides. For GI irritation, you could have none or just some occasional issues with polysaccharides, but you will definitely have them with ferrous salts and they can be severe.

Ferrous salts have a very low absorption rate while polysaccharides have a high rate of absorption. Above all else, you want your supplements to be effective. They need to work the way they are supposed to and give you the result that they promise. We worked hard to include only the best and most effective iron supplements available on our guide.

Taking a supplement that does not work is like throwing away money and no one wants to do that. We understand that you are looking to us for assistance finding the best products on the market and we take that responsibility seriously. That is why we hope this guide to iron supplements will be a help to you!
