A new study out of the Mayo Clinic (with a partner in South Korea) found that low-dose naltrexone seems both to work just great for combating the symptoms of fibromyalgia. It was already used off-label for that purpose, but the authors wanted to add a dose of science — to “systematically assess the current evidence.”

Voila! In looking at the studies out there, they found that LDN helped manage the symptoms of fibromyalgia with “no severe adverse events were reported.”
