Iron

Also known as: Ferrous sulfate, ferrous fumarate, ferric maltol, Ferrograd, Spatone

An essential mineral for red blood cell production and oxygen transport. Iron deficiency and iron deficiency anaemia are common in women of reproductive age due to menstrual blood loss, and in perimenopause when cycles may become heavier. Symptoms overlap significantly with menopausal symptoms, including fatigue, brain fog, and mood changes.

Research Context

Research context compiled from published sources

How does Iron work?

Iron is required for haemoglobin synthesis (oxygen transport) and myoglobin (muscle oxygen storage). It is also a cofactor for mitochondrial enzymes involved in energy production. Iron deficiency impairs these functions, causing fatigue, cognitive impairment, and reduced exercise tolerance before anaemia develops.

Research Depth

Well Studied

Extensive human research over many years, including randomized controlled trials.

Long-Term Evidence

Well Characterized

Decades of long-term safety data available from human use.
