Active Iron aims to tackle common nutritional deficiencies around the world.
We improve millions of lives by optimising supplements for common nutritional deficiencies.
What’s different about Active Iron? It’s all about no compromise.

Active Iron is different…

Our non-constipating formula helps reduce gut irritation from iron. Our products are clinically proven to deliver 2X better absorption of iron sulfate⁴, increasing iron levels by 94%.

Women have been putting up with the side effects of iron supplements for too long.

Our iron supplements utilise a ground-breaking new method of delivering iron. By targeting the natural site of iron absorption in the body, our new system reduces the common side effects women experience from iron supplements. Active Iron was developed by a team of scientists from Trinity College Dublin, Dublin’s premier University. 

How does it work?

Active Iron’s ground-breaking protein formula targets the site where the body naturally absorbs iron, the DMT-1, which increases the amount of iron absorbed. Active Iron is 6X less likely to cause gut irritation⁵ compared to other iron supplements, meaning it’s kind on your stomach.

Our Experts.

Research & Development.

Our mission is to create products that deliver on significant unmet clinical needs. Through ground-breaking innovation and cutting-edge research, we have developed a number of new technologies that will provide better patient outcomes.

Active Iron 2.0

Professor Mark Ledwidge and his research team continue to investigate new applications in oral iron and the leading asset, Active Iron 2.0, is a novel iron formulation. It has been developed from a range of non-protein carriers, designed to provide strong efficacy, tolerability and stability while additionally presenting in a soluble and palatable solution.
With anaemia of chronic disease common in an ageing adult population there is a need for a well-tolerated oral iron that is also in an easy-to-take form. Active Iron 2.0 is a water-soluble iron solution, applicable in a medical setting targeting an unmet need for people who have difficulty taking tablets i.e. elderly and paediatrics.

Anti-Inflammatory Platform.

Research teams at Trinity College Dublin & Solvotrin have discovered a family of novel compounds under the stewardship of Professor John Gilmer.

Professor Aideen Long is another leading immunologist based at St James’s Hospital Trinity Translational Institute who showed the compounds work by slowing T-cell division. These are the main disease drivers in inflammatory conditions such as psoriasis, but they can proliferate uncontrollably in a related set of malignant diseases termed cutaneous T-cell lymphoma (CTCL).

The compounds were subsequently shown to inhibit multiple pathways of disease that are dysregulated in cancer and inflammatory conditions including psoriasis. These pathways include STAT3 family proteins and AKT, a key mediator of cell survival and inflammation.

Dr Anne Marie Byrne (Solvotrin) is coordinating the development of this technology towards clinical trials in collaboration with Enterprise Ireland and Trinity, and expert clinicians in the CTCL field.

Our lead compound is rapidly broken down by skin esterases to substances that are Generally Regarded as Safe (GRAS) in human use, thus ensuring a lower Toxicology risk.

It inhibits proliferation of a range of T-cell lines derived from Cutaneous T-Cell Lymphoma (CTCL) patients but appears to have no effect on non-malignant cell types such as skin cells (Keratinocytes), normal T cells (PBMCs). The compounds were shown to inhibit cell growth and multiplication, and they do not induce apoptosis.

It is envisaged that this technology will be spun out into a new company and funded separately in late 2022.
