Investigating the effects of co-supplementation with alpha-linolenic acid and L-carnitine on inflammatory status, oxidative stress, clinical symptoms, mental health and quality of life in women with migraine: a protocol for a randomized, triple-blind, placebo-controlled trial
Abstract
Background: Migraine is a severe neurological disorder that is recognized as one of the most common debilitating diseases worldwide. Although the exact cause of migraine is not known, research suggests that inflammation, oxidative stress, mitochondrial dysfunction, and insufficient nutrients may contribute to its development. Studies indicate that nutrition-based approaches are safer and more cost-effective strategies for managing migraine symptoms compared to medication. In this regard, the impact of nutrition, as a complementary medicine, is largely attributed to that of certain nutrients on inflammation and mitochondrial function. It is hypothesized that alpha-linolenic acid and L-carnitine, which possess anti-inflammatory and antioxidant properties, may be synergically beneficial for migraine patients. Therefore, this study will be conducted to assess the efficacy of alpha-linolenic acid and L-carnitine co-supplementation in patients with migraine.
Methods: This is a parallel, randomized, triple-blind, placebo-controlled clinical trial, in which 80 women aged 20 to 50 years with migraine will be assigned to receive either intervention group (n = 40) receiving both 1000 mg/day flaxseed oil and 500 mg/day L-carnitine simultaneously for 12 weeks, or control group (n = 40) receiving both 1000 mg/day paraffin oil and 500 mg/day maltodextrin as the placebos for the same duration. The primary outcomes include changes in clinical symptoms of migraine, including frequency,…
How strong is the evidence?
Evidence Hub reads this as a randomized trial, done in people. Its evidence level is 2 of 5 (High · randomized trial). Randomized trials of a reasonable size are the strongest single-study design. Reported size: 80 participants or records.
