The Dangers of Iron Deficiency?

Iron deficiency is the most common nutritional deficiency globally, affecting around 30% of the population, according to the World Health Organisation (WHO, 2021). Your body needs iron in order to produce haemoglobin (the protein contained in red blood cells that transports oxygen around our body). When we don't get enough iron, we can feel fatigued and weak, and that's just for starters.

That's why iron supplements can be a great option to ensure that your body is getting the nutrients it needs to help us function at full power. When our bodies have optimal iron, we feel energised, we can focus properly, and we feel full of vitality. So, if you're not sure if you need an iron supplement, read on.

Our experts break down the benefits, what to look for and The Best 5 Iron Supplements in 2025.

Symptoms of Iron Deficiency

Here are some common signs that your body may need an iron boost:

Persistent Fatigue

Waking up exhausted after a full night’s sleep? You may be iron deficient.
Pale Skin

Losing your healthy glow even in the summer? It might be time to assess your iron intake.
Shortness of Breath

If you find yourself running out of steam earlier than you normally would, you could be suffering from a lack of iron.
Frequent Illness

Iron deficiency can lead to a compromised immune system. If you’re suddenly catching more colds than usual despite plenty of vitamin C, iron could be the cause.
Cold Extremities

Iron deficiency can lead to poor circulation, meaning if your hands and feet are constantly cold, it could be time for a supplement.

Benefits of High Quality Iron Supplements

Iron supplements can be a very effective way to boost your health and energy levels. Here are some key benefits:

Boosts Energy Levels

Iron supports haemoglobin production, helping deliver oxygen to muscles and tissues, so you feel energised throughout the day (Clark, 2020).
Supports Cognitive Function

Adequate iron is vital for brain health, memory, and focus, making it essential for your mental sharpness (Beard, 2003).
Strengthens Immunity

Iron plays a key role in fortifying your immune system, helping your body fight off illness (World Health Organisation, 2021).
Promotes Healthy Blood Cells

Iron aids in the production of red blood cells, ensuring efficient oxygen transport and overall vitality (Killip et al., 2007).

What To Look For?

Not all Iron supplements are the same. It's important to choose quality, proven formulas from trusted brands to see real benefits.

Iron Bisglycinate A gentle, easily absorbed form of iron that's effective without causing digestive discomfort (Ashmead et al., 2015).
Vitamin C Enhances iron absorption and supports immune health (Teucher et al., 2004).
B Vitamins (B6, B12 & Folic Acid) B vitamins support red blood cell production and energy metabolism (Bailey, 2010).
Money-Back Guarantee With many brands offering dubious formulations, it is important to choose trusted, locally-manufactured brands that offer guarantees on their products. Leading brands sometimes offer a 30 or 60 day money back guarantee.

What Should I Avoid?

Amazon Sellers Lately there has been an increase in unscrupulous sellers pushing counterfeit or even falsely labelled formulations, particularly on third party marketplaces. We recommend going direct to trusted brands.
Low Dosages An iron supplement should contain at least 15 mg of iron in every dose serving to ensure you avoid deficiency.
Unclear Form of Iron Some supplements don't specify which form of iron they use, which can impact bioavailability and absorption. Always choose supplements that clearly state they use Iron Bisglycinate.
