Is this trial a fit for you?

Likely a good fit

Adults aged 18 and older with diagnosed painful diabetic peripheral neuropathy and documented type 2 diabetes.

Probably not a fit

Individuals without diabetes or without PDPN, or those with chronic conditions or medications that confound outcomes, may not experience benefit.

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This is a prospective, double-blind, randomized controlled trial conducted at endocrinology clinics in Jordan. Adults with painful diabetic peripheral neuropathy and type 2 diabetes are randomized to receive either 500 mg of Ceylon cinnamon twice daily plus standard care or a matching placebo for six months. The study aims to see if cinnamon can favorably modify metabolic markers and pain intensity compared with standard care alone. Outcomes include blood glucose, lipid profile, body mass index, and pain scores, with attention to safety and tolerability. The trial addresses the potential role of a plant-based nutraceutical as an adjunct to conventional management of PDPN.

Why it matters

Potential benefit: If successful, participants may experience better blood sugar control, improved lipid levels, weight trends, and reduced neuropathic pain.

How similar studies have gone: Previous research on cinnamon suggests potential metabolic and anti-inflammatory effects, but robust evidence for PDPN-specific benefits remains limited.
