Top 5 Best Iron Supplement for Pregnancy

1. Solgar Gentle Iron

  • Type: Capsule
  • Dose: 25MG
  • Iron: Ferrous bi-glycinate

Our Verdict

The Solgar Gentle Iron are our best rated supplements for pregnant women. We are highly recommended them if you usually have tummy troubles when taking iron. They are also non-constipating due to the type of iron used. Although it’s a small dose of iron studies have shown that 25mg of iron bi-glycinate is as effective as 50mg of iron sulphate. That means less tablets to take to tackle your anemia. The capsules are regular size around about the length of a cent. If you have borderline severe anemia check out our next recommendation.

2. Ferro-Sequels High Potency Iron

  • Type: Capsules
  • Dose: 65mg
  • Iron: Ferrous Fumarate

Our Verdict

The Ferro-Sequels high potency iron is the best option for high strength iron. These tablets are very effective at building up your iron levels quickly. We would highly recommend them if you are close to needing an IV iron drip or very close to your due date with anemia. They contain vitamin c which makes the body absorb more of the supplement. The slow release formula makes them very easy on the stomach and reduces side effect such as nausea and diarrhea.

3. Nature’s Plus Iron

  • Type: Chewable
  • Dose: 27mg
  • Iron: Ferrous Fumarate

Our Verdict

The Natures Plus chewable iron tablets are perfect if you find it hard to swallow capsules. Unlike regular iron tablets they taste really nice, which make them easier to take every day. The tablet is the size of a nickel and because they are chewable you won’t need to force the down. They contain 27mg iron so you may need to take a few a day depending on how severe your anaemia is. With added vitamin c you won’t need to worry about taking extra vitamins to help absorb as much as possible.

4. Floradix Floravital Iron

  • Type: Liquid
  • Dose: 10mg
  • Iron: Ferrous Gluconate

Our Verdict

Floradix liquid iron is highly recommended by obstetricians and midwives. If you struggle to swallow tablet iron then a liquid may suit you. The liquid is very gentle on the stomach and will digest without causing upset or vomiting. It’s suitable for both vegetarians and vegans as there are no binders or capsules. The taste is quite strong, however you can add it to a cherry or grape flavoured juice to mask it. This liquid is also a great option if you want an iron supplement which is gluten-free.

5. Garden of Life Vitamin Code Iron

  • Type: Capsule
  • Dose: 22mg
  • Iron: Non- Haem

Our Verdict

The Garden of Life Vitamin Code Iron is a great capsule alternative to the Floradix. The brand is focused on providing organic vitamin derived from plants. As this is a non-haem iron we strongly recommend using with a vitamin c supplement to improve the absorbency. It’s much easier on the digestive system and won’t leave you feeling constipated after regular use.

Type of Iron Supplement

The type of iron supplement has a huge effect on how easy it is for you to take. There are four common types available.

  • Capsules – This is the most common type. They usually are the most potent type of iron and can be harsh on the stomach. You will need to check if they contain binders or ingredients which are suitable for your diet e.g. vegetarian, soy/gluten free.
  • Liquid – This type is a great option for those who have trouble swallowing tablet forms.  You can add juice to mask the taste as it’s usually very strong. Liquid is often suitable for most diets and are easier on the stomach. The iron levels are usually lower in liquid forms.
  • Chewable – A great in-between for liquid and tablets. If you need a stronger dose but hate to swallow hard capsules a chewable supplement is great. They often have a metallic or chalky taste to them, however, women usually find them easier to stomach than capsules.
  • Soft Gels – Not as commonly available as the other types. They are easier to take than capsules and have a softer effect on the tummy. Check the ingredients of the capsule as often they are usually aren’t suitable for vegetarians.
