What are the
benefits of iron?

Iron is essential to life. It contributes to the reduction of tiredness and fatigue and also plays an important role in normal energy metabolism, oxygen transport, cognitive function, immune function and formation of red blood cells and haemoglobin.

Iron has many functions in the human body:

  • It allows oxygen to be transported in red blood cells
  • Helps to ensure proper functioning of the immune system
  • Helps to reduce tiredness and fatigue
  • Supports cognitive function
  • Contributes to normal energy production

Sources of Iron

There are two factors that make up how much iron you’re getting, iron content (the amount of elemental iron you are getting) and bioavailability (how much iron you are able to absorb and use).

You can get iron from food, but depending on the type, it may not be absorbed well and it may not be sufficient to meet your requirements.

There are two types of iron found in the diet, non-haem and haem. Non-haem iron is found in plants, nuts and legumes. This type of iron is absorbed at a much lower rate than heme iron, which is found in animal products such as meat, especially red meat.

Even if you are making a conscious effort to ingest more haem iron, daily habits like drinking tea and coffee after your meals can reduce iron absorption and reduce your iron intake.

Cooking and freezing meat can reduce heme iron content. Also, there are naturally occurring compounds in vegetables (phytates, polyphenols, tannins) and in milk and eggs that can prevent iron absorption.

If you are unable to meet your iron needs through your diet, supplements are a proven option.

Choosing the right iron tablet for you

Considered the ‘gold standard’ in iron supplementation, ferrous sulfate (also spelled sulphate) is the most common form of iron in iron supplements. This is for good reason, it is soluble and considered to be the most bioavailable form. However, this ‘iron’ sulphate has been known to cause gut irritation at high doses. Together with a team of scientists in Trinity College Dublin we have created Active Iron, a new formulation that uses a denatured whey protein.

This ground-breaking formula ensures that iron is carried to the natural site of absorption in the small intestine, DMT-1, helping to reduce gut irritation from iron and the need for iron carriers such as Vitamin C. That is why Active Iron can be taken on an empty stomach.

Why choose Active Iron?

Active Iron’s unique non-constipating iron formulation is clinically proven to have x2 the absorption compared to the gold standard, iron sulphate. Active Iron targets the natural site of iron absorption in the intestine, increasing the amount of iron absorbed and making more iron available to your body.

Active Iron’s advanced protein formulation is non-irritating to the stomach and does not cause inflammation, this prevents unwanted side-effects such as stomach pain, cramps, sickness, constipation and flatulence. Active Iron is gentle enough to take on an empty stomach, and gives you strong absorption when you need it.
