What is Restless Legs Syndrome?

Restless Legs Syndrome (RLS), also known as Willis-Ekbom disease, is a neurological disorder characterised by an irresistible urge to move to stop uncomfortable or odd sensations. As it usually interferes with sleep, it is also considered a sleep disorder.

Although its name indicates that it affects the legs, RLS can affect the arms, torso, head, and other parts of the body. Moving the affected body part can temporarily suspend the sensations associated with RLS, thereby providing temporary relief.

Primary RLS

Primary (idiopathic) RLS has no known cause and usually begins slowly, before approximately 40–45 years of age. Often genetically linked, Primary RLS can come and go and get worse with age.

Secondary RLS

Secondary RLS often has a sudden onset and is usually associated with another medical condition (e.g. iron deficiency anaemia) or the use of certain drugs like SSRI’s and SNRI’s.

Why Iron Deficiency is NOT just low iron

There are a number of factors that affect overall RLS-related Iron level

Serum Ferritin Level

There is very high correlation between the onset of RLS symptoms and ferritin levels below 100ug/l

For anyone affected by this, raising ferritin levels may have positive benefits.

Fighting Hepcidin Activity

In the presence of Iron, the body produces Hepcidin which restricts Iron absorption.

Combating Hepcidin level is a key component of raising the underlying Iron level in the body.

The Restful Iron Lull

30-60 mins after falling asleep the brain begins closing iron channels resulting in lower availability.

A key issue amongst RLS sufferers, reducing the effects of the Restful Iron Lull can improve sleep quality.

The Root Cause Mechanisms of RLS

The key imbalances that trigger the symptoms of Restless Legs Syndrome are:

Iron Transport & Brain Availability

Problem: Low Iron

RLS is strongly associated with reduced iron in the substantia nigra despite normal blood levels. Supporting absorption + crossing the BBB is foundational.

Magnesium & Neuromuscular Stability

Problem: Low Magnesium

Magnesium threonate improves CNS delivery, supporting sensory gating and excitability reduction.
