When oral iron causes side-effects, Active Iron is the answer!

As you know, one of the main challenges with iron is tolerability. Evidence suggests around 80-90% of those who take iron supplements report side effects, and of those around 30% will stop taking them because of these side effects.

Active Iron is a next generation iron supplement that is specially formulated to reduce the negative gastro-intestinal side effects associated with traditional oral iron preparations, including nausea, constipation, and diarrhea.

Guide To Iron Supplementation In Pregnancy

The demand for iron increases threefold during pregnancy to meet the demands of the growing fetus and placenta, as well as maternal adaptations to pregnancy.1 It is estimated that 30-40% of pregnant women in industrialised countries are iron deficient and almost one in four women in the UK have iron deficiency anaemia. Treating iron deficiency offers considerable benefits to both mother and baby.

This guide outlines the role of iron in pregnancy and foetal development, how dietary iron insufficiency occurs, current NICE guidance on iron deficiency in pregnancy, and iron supplementation.

Why Choose Active Iron?

The Science Of Active Iron

Active Iron’s ground breaking protein formula helps reduce irritation from iron, meaning it’s kind enough to take on an empty stomach. Active Iron targets your body’s normal ‘iron absorber’ called the DMT-1. This means that it is strong on absorption and in tune with your body’s needs.

Innovative Solution For Powerful Yet Gentle Iron Intake

Whilst ferrous sulfate is the current ‘gold-standard’ iron supplement, it is not without unfavourable side-effects. Specially formulated to help prevent constipation, Active Iron’s new iron capsules are designed to solve these problems. What makes Active Iron special is that the iron supplement is contained within a special protein microsphere made from denatured (inactivated) whey protein. The gut is protected from damage from iron while the iron is carried to the precise site it is needed and is best absorbed.

Breakthrough Iron Supplement Formulation

Active Iron contains 14mg iron per capsule - equivalent to 100% NRV . Users can be assured that they are achieving dietary targets and taking a form of iron that is well absorbed. Active Iron is gluten free and sugar free, and free from artificial preservatives. The iron pills are vegetarian, gluten free, lactose free, sugar free and free from artificial preservatives.

The Active Iron formulation doubles the amount of iron absorbed compared to iron sulfate, while being so gentle on the gastric system it can be taken on an empty stomach. Active Iron is suitable for use during pregnancy and breastfeeding. It is also suitable for vegetarians, free from artificial preservatives, yeast, gluten, lactose, and sugar.

Clinically Proven
