Creatine Supplementation and Restless Legs Syndrome: Guideline Evidence

Exacerbating Factors for Restless Legs Syndrome

The American Academy of Sleep Medicine (AASM) guideline recommends that the first step in managing RLS is to identify and address known exacerbating factors, which include alcohol consumption, caffeine intake, antihistaminergic medications, serotonergic medications, antidopaminergic medications, and untreated obstructive sleep apnea. 1
Alcohol use is listed as an RLS‑exacerbating factor in the AASM guideline. 1
Caffeine consumption is listed as an RLS‑exacerbating factor in the AASM guideline. 1
Antihistaminergic medications are listed as an RLS‑exacerbating factor in the AASM guideline. 1
Serotonergic medications are listed as an RLS‑exacerbating factor in the AASM guideline. 1
Antidopaminergic medications are listed as an RLS‑exacerbating factor in the AASM guideline. 1
Untreated obstructive sleep apnea is listed as an RLS‑exacerbating factor in the AASM guideline. 1

Creatine supplementation is notably absent from the AASM guideline’s comprehensive list of RLS‑exacerbating agents, indicating it is not considered a risk factor for worsening RLS symptoms. 1

The AASM guideline provides no evidence‑based reason to avoid or discontinue creatine supplementation in patients with RLS; the supplement is not mentioned as a causative or exacerbating factor in the guideline. 1
