Periods! They’re normal, they’re ordinary, and they’re a part of every woman’s life—yet society has habitually stigmatized the subject of menstruation, and discouraged the general public from discussing it openly. As we progress as a society into the 21st century and...

FAQs.

Who needs iron supplements?

Certain segments of the population are more prone to inadequate iron levels, and turn to iron supplements to keep their iron levels up.

Women of childbearing age require up to 2X more iron than men of the same age, as blood loss during menstruation depletes the body of iron. Women who experience heavy periods are especially at risk of developing inadequate iron, and many find that a daily iron supplement helps restore their iron and energy levels.

During pregnancy, a woman’s iron needs increase 2-3 fold, needing as much as 30-60 mg a day, according to the World Health Organisation. After birth, it can take up to a couple months for iron levels to reach pre-pregnancy levels. Active Iron is suitable for conception, pregnancy, and breastfeeding. 

Those on a plant-based diet, such as vegetarians, are another group who regularly turn to iron supplements. While we get iron from food, the iron found in plant-based sources contain non-haem iron, which is harder for our body to absorb than haem iron, the type found in meat. Thus, while a vegetarian’s diet may be high in iron-rich foods, they may still have inadequate iron levels, in which case supplementation is recommended.

Heavy exercisers, especially those who practice endurance sports such as cycling, rowing, or marathon running, often find themselves experiencing depleted iron stores. Our body requires iron to build muscles and keep us energised, so those regularly exercising may benefit from daily iron supplementation. 

Which iron supplement is best?

When choosing an iron supplement, it is important to consider two factors: how much iron is available for absorption, and how likely the supplement is to cause unpleasant side effects.

In clinical studies, Active Iron’s unique formula helps avoid gut irritation*. Most iron supplements and tablets dissolve and oxidise in the stomach; this can cause unpleasant and sometimes severe gastrointestinal side effects (such as stomach upset and constipation). Active Iron is different, its unique formula is clinically proven to provide 2X better absorption**. As a result, more iron is available for the body to absorb, helping to avoid the common side effects.

*Ledwidge et al. Data on file. **Wang et al. 2017, Acta Haematological, 138: 223-232

How many mg of iron do we need per day?

Women of childbearing age need 14mg of iron per day. Pregnant women require up to 30mg per day. Men and menopausal women require 9mg per day. Higher doses of iron are often needed for for people with heavy periods, partake in endurance sports and have impaired iron absorption.

A blood test will determine haemoglobin and ferritin (storage iron) levels. Clinical studies have shown that people can increase their iron levels by 94% in 6 weeks with Active Iron*.

Why should you choose Active Iron’s iron supplements?

Every day, Healthcare professionals are recommending Active Iron to their patients.

Most iron supplements and tablets dissolve and oxidise in the stomach; this can cause unpleasant and sometimes severe gastrointestinal side effects (such as stomach upset and constipation). Active Iron is different, its unique formula provides 2X better absorption*. As a result, more iron is available for the body to absorb, helping to avoid the common side effects**.

Clinical studies have demonstrated that Active Iron increases iron and energy levels whilst helping to prevent gut irritation.

What are the side effects of iron supplementation?

The common side effects of iron supplements include nausea, constipation, diarrhoea, black stools and tooth staining.

Iron is poorly absorbed by the body and many formulations in the market claim to reduce or avoid the common side effects. Some examples include:

1. Reducing the dose significantly which can reduce the side effects. However, this can often mean to dont get sufficient iron. 

2. Adding Vitamin C as an antioxidant to try and counteract some of the oxidative stress associated with iron. 

3. Use a different form of iron and or a ferric iron. 

Active Iron is different, its unique formula provides 2X better absorption*. As a result, more iron is available for the body to absorb, helping to avoid the common side effects**.

Can you take iron supplements without seeing a doctor?

Yes, as Active Iron is a food supplement (and not a medicine) it is suitable to take without consulting a GP. We recommend Active Iron only to those who are at risk of developing low iron levels (i.e those with regular periods, pregnant & postnatal, vegetarians, heavy exercisers).

Is there any risk of iron overdose with Active Iron?

There is an inherited condition called haemochromatosis where iron levels build up slowly over many years. Women with periods will have a slower build up than men as there will be iron loss monthly. There is no way of knowing you have this condition unless you have the genetic screening for it.

Active Iron is a low dose product (from 14mg to 25mg) that is 2X better absorbed compared to other iron supplements. We recommend Active Iron only to those who are at risk of developing low iron levels (i.e those with regular periods, pregnant, vegetarians, heavy exercisers) or have low iron levels.

14mg of iron is the recommended daily allowance for iron set by the regulator (EFSA). 14mg would be considered safe based on daily intake for the average person. A tolerable upper limit of 45mg has been recommended for iron and this is based on tolerability of iron products.

How does Active Iron differ to prescribed iron or liquid iron?

Active Iron is a food supplement and not a medicine, meaning our products contain 100-179% of the recommended daily allowance of iron, whereas prescription iron has a higher dose. For example, prescription iron may contain 100mg elemental iron. The issue with high dose iron is that it oxidises in the gut and as a result it is poorly absorbed (typically just 10% is absorbed). It is this oxidation and poor absorption that causes gastrointestinal side effects such as nausea and constipation in 8/10 people. Typically, 50% of people stop taking iron as a result of these side effects.

Most liquid iron supplements contain a much lower dose of iron which is why they can avoid these common side effects. Although this is a great benefit, they often do not provide sufficient iron to increase iron levels with some only containing 5mg iron per serving.

Active Iron is different. Unlike other oral iron it’s whey protein formula protects the iron from oxidation allowing for 2X better absorption.  As a result Active Iron is clinically proven to increase iron levels by 94% and is gentle on the stomach, helping to prevent gastrointestinal side effects and allowing for 4X better compliance in taking the product.

How does Active Iron help alleviate menstrual fatigue?

Blood loss = iron loss = low iron = menstrual fatigue. Menstruation is the leading cause of iron, resulting in 1 in 4 women having low iron levels. Active Iron is clinically proven to increase iron and energy levels to help combat tiredness and fatigue throughout a woman’s cycle.
