Iron is an essential mineral your body requires for everything from carrying oxygen throughout your body, to helping you feel energized. But many don't get enough, and this is where iron supplements come in. But which iron supplements are best? We've rounded up some of our favourites.

First, let’s explore why it’s difficult for your body to absorb iron in the first place.

Why You Can Become Deficient in Iron

You get iron from your diet, but a few factors influence how much you absorb, including the type of iron, the presence of other nutrients, and other lifestyle factors.

There are two forms of iron, let’s explore them:

Heme iron is found in animal-based foods and it's more easily absorbed by the body. Non-heme iron is found in plant-based foods like beans, lentils, and spinach. Non-heme iron is harder for the body to absorb than heme.

Lastly, blood loss or menstruation can cause a decrease in iron. Therefore, women who get a period may be more likely to become deficient in iron. Additionally, adolescent women and athletes are at further risk of iron deficiency as well.

What Happens When You Don't Get Enough Iron?

Iron deficiency is more common than you may think. In fact, it is the most common nutrient deficiency worldwide. Being deficient in iron can cause a number of symptoms and health complications, including fatigue, weakness, dizziness, hair loss, pale skin, shortness of breath, brittle nails, and poor concentration.

If left untreated, iron deficiency can progress to iron-deficiency anemia. This condition is characterized by a severe depletion of iron stores and hemoglobin in the body.

But before you head to the store to purchase an iron supplement, it's worth pointing out that you should always have your iron blood levels tested first.

6 Top Iron Supplements

1) Floradix Iron Liquid: Floradix Iron Liquid is a very popular iron supplement known for its easy absorption and gentle formulation. It contains ferrous gluconate, which is well-tolerated and easily absorbed by the body. This formulation also contains nutrients that further enhance the absorption of iron. These nutrients include a vitamin b complex, vitamin c and iron-rich herbal extracts. Floradix is suitable for those with difficulty swallowing tablets or capsules, and it's ideal for individuals with sensitive stomachs. Floradix Iron Liquid is so gentle it is often recommended for women, pregnant individuals, athletes, and vegetarians who may need additional iron support.

2) Floradix Iron Tablets: For those who prefer a convenient tablet form, Floradix Iron Tablets offer an easy option. Made with the same great formula as the liquid variety, Floradix Iron Tablets are suitable for individuals who prefer the convenience of tablets (tablets are a great option when travelling or on the go).

3) Heme Iron: sourced from animal-based sources, which offers greater bioavailability. This means they are typically well-absorbed by the body. This form of iron is often prescribed to those with a severe iron deficiency or who are anemic. However, since heme iron supplements are derived from animal sources, they are not suitable for vegans or vegetarians.

4) Iron Bisglycinate: this form of iron is vegetarian-based and known for being absorbable and gentle. This form is more gentle on the stomach and digestive tract.

5) Spatone: Spatone is a unique iron supplement that provides a pure and low dose of iron. Spatone contains naturally occurring iron which is easily absorbed by the body (up to 40%), plus trace minerals. Spatone is a convenient option as it comes in individual sachets that easily mix into water or juice. If you struggle to swallow tablets and travel a lot, Spatone is likely a great option. Keep in mind that if you are anemic, Spatone should be avoided as it does not contain a high enough dose of iron.

6) Anemia Combinations: Some iron supplements contain additional nutrients that work synergistically to support optimal iron absorption and utilization in the body. Copper can help with iron absorption, while vitamin C can enhance the absorption of non-heme iron. Vitamin B12 is important for red blood cell production and overall energy metabolism, making it a valuable addition to iron supplements. Anemia Combinations can benefit individuals with increased iron needs, including pregnant women, athletes, or those with more severe iron deficiency.

Iron Supplement Safety

  • Don't take too much iron. Follow the recommended dosage instructions from your healthcare provider.
  • Iron supplements can also interact with certain medications. Check with your health care practitioner to ensure it can be safely taken alongside an iron supplement. 
  • Timing is everything. Taking your iron supplement on an empty stomach will increase its absorption. Take your iron supplements at least two hours away from antibiotics, antacids, and calcium supplements to avoid interactions and further enhance absorption.
  • Side effects can happen. These usually include nausea, vomiting and constipation.

By following these guidelines, you can ensure that you get the most from your iron supplement, helping you maintain better energy and vitality for everything you do.
