Effects of Acetyl L-Carnitine Supplementation on Clinical, Metabolic and Inflammatory Symptoms in Obese, Diabetic, Postmenopausal Women With Osteoarthritis

14 september 2026 bijgewerkt door: Khyber Medical University Peshawar

Effects of Acetyl L-Carnitine Supplementation on Clinical, Metabolic and Inflammatory Symptoms in Obese, Diabetic, Postmenopausal Women With Osteoarthritis: Randomized Controlled Trial

OA is a degenerative bone disease more common in postmenopausal women. Diabetes and obesity are common risk factors for the development of OA. The common symptoms include pain and disability of the affected joint, leading to mobility issues. Acetyl L-carnitine due to its known anti-inflammatory, chondroprotective, and improved insulin-sensitizing effects may help in alleviating the symptoms and progression of OA in obese diabetic postmenopausal women.

Studie Overzicht

Gedetailleerde beschrijving

Osteoarthritis (OA) is a chronic degenerative joint disease that commonly affects older adults and is associated with pain, stiffness, reduced mobility, and disability. The coexistence of obesity and type 2 diabetes mellitus may aggravate the progression and severity of OA through metabolic dysfunction, chronic low-grade inflammation, oxidative stress, and altered adipokine profiles. Postmenopausal women are particularly vulnerable because hormonal changes contribute to increased inflammation, obesity, insulin resistance, and joint degeneration.

Acetyl L-Carnitine is a naturally occurring compound involved in mitochondrial energy metabolism. Previous studies have demonstrated anti-inflammatory, antioxidant, and metabolic benefits of Acetyl L-Carnitine, including improvements in insulin resistance, lipid metabolism, oxidative stress, and inflammatory cytokine production. Experimental studies have also suggested chondroprotective effects through enhancement of cartilage matrix synthesis and mitochondrial function.

This double-blind, placebo-controlled randomized clinical trial will enroll 100 obese, diabetic, postmenopausal women with radiologically confirmed osteoarthritis. Participants will be randomly assigned to receive either Acetyl L-Carnitine (1.5 g twice daily) or placebo for 12 weeks in addition to conventional osteoarthritis treatment.

Clinical outcomes will include assessment of osteoarthritis symptoms using the Western Ontario and McMaster Universities Osteoarthritis Index (WOMAC), radiological severity using the Kellgren-Lawrence grading system, perceived stress, and depression, anxiety and stress scores. Laboratory outcomes will include glycemic profile, lipid profile, insulin resistance markers, inflammatory biomarkers (CRP and IL-6), oxidative stress markers, adipokines, stress hormones, and complete blood count parameters.

The study seeks to determine whether Acetyl L-Carnitine supplementation can improve clinical, metabolic, inflammatory, and radiological outcomes in obese, diabetic, postmenopausal women with osteoarthritis.
