      <study_design>Randomization: Randomized, Blinding: Double blinded, Placebo: Used, Assignment: Parallel, Purpose: Prevention, Randomization description: In the current study, patients with migraine referred to the neurology clinic of Allameh Bohloul Gonabadi Hospital were selected using available sampling technique. If they want to participate in the study and meet the entry criteria, written and informed consent will be obtained from them. Then, in order to assign the patients to two intervention and control groups, he used the method of quadruple permutation blocks in such a way that first six possible states of the blocks (BAAB, ABBA, BABA, BBAA, ABAB, AABB) were listed and to each block one number of One to six will be allocated and will be used for four patients. Then, a number between one and six is randomly selected using the random number table, and then people are assigned to the control group (A) and the intervention group (B) based on the block corresponding to the selected number. It will continue until the end of the sample size, Blinding description: In the intervention group, L-carnitine tablets of 500 mg once a day will be crushed and placed inside the capsule and will be added to the routine migraine prophylaxis treatment. . In the control group, routine prophylaxis treatment and identical placebo are used instead of L-carnitine. People in both the intervention and control groups will receive the necessary training from the researcher about the objectives of the study, the benefits of studying how and how much to consume L-carnitine, the exclusion criteria, and the duration of the intervention. did
The control and intervention groups are marked with two codes A and B, and the outcome evaluation physician and the analyst will not be aware of the nature of these two groups for data analysis.</study_design>
