Plain language summary
Fibromyalgia (FM) is characterised by widespread chronic pain, fatigue, sleep disturbances, and cognitive impairment. As a result of oxidative stress, reactive oxygen species (ROS) are produced and improperly disposed of, resulting in peripheral and central sensitisations, and a reduction of the pain threshold in FM patients. It is well known that antioxidants are protective against oxidative stress and that reducing antioxidant levels can result in increased pain in patients with FM. An overview of 17 studies was conducted to evaluate the effect of antioxidant supplementation on pain perception and the appropriate duration of treatment for FM patients in this systematic review. This systematic review found that supplementation with Fibromyalgine® (Fib) (that contains vitamin C, acerola ginger root, and freeze-dried royal jelly), 300-400 gm/d of coenzyme Q10 alone in combination with Pregabalin, ferric carboxymaltose, vitamin C, E, and Nigella sativa, magnesium + amitriptyline, acetyl L-carnitine, and Sun Chlorella™ green algae are effective in reducing pain perception in FM patients. In patients with FM, alpha-lipoic acid supplementation significantly reduced pain scores. 80% of FM patients reported reduced pain after supplement treatment for at least six weeks. There is a need for further robust long-term studies to confirm the effectiveness and clinical applicability of antioxidants in the management of FM, as well as to identify the pathophysiology of FM. This research may, however, be used by healthcare professionals to gain a better understanding of the potential benefits of antioxidants in the treatment of pain associated with FM.
Abstract
In recent years, antioxidant supplements have become popular to counteract the effects of oxidative stress in fibromyalgia and one of its most distressing symptoms, pain. The aim of this systematic review was to summarize the effects of antioxidant supplementation on pain levels perceived by patients diagnosed with fibromyalgia. The words used respected the medical search terms related to our objective including antioxidants, fibromyalgia, pain, and supplementation. Seventeen relevant articles were identified within Medline (PubMed), Scopus, Web of Science (WOS), the Cochrane Database of Systematic Review, and the Cochrane Central Register of Controlled Trials. This review found that antioxidant supplementation is efficient in reducing pain in nine of the studies reviewed. Studies with a duration of supplementation of at least 6 weeks showed a benefit on pain perception in 80% of the patients included in these studies. The benefits shown by vitamins and coenzyme Q10 are remarkable. Further research is needed to identify the effects of other types of antioxidants, such as extra virgin olive oil and turmeric. More homogeneous interventions in terms of antioxidant doses administered and duration would allow the effects on pain to be addressed more comprehensively.

Plain language summary
Fibromyalgia (FM) is a chronic non-degenerative disease of unknown etiology without effective medical treatment that mostly affects women. The aim of this study was to evaluate the efficacy of mainly plant-based diets in patients with FM compared to omnivorous diets. A secondary aim was to examine the main effects of these diets on patients’ symptoms and the improvement in their quality of life. This study is a systemic review of six studies (n = 4 clinical trials and n = 2 observational cohort studies). The selected studies included 157 FM patients in both the intervention and control groups, and more than 117 were women. Results indicate that a mainly plant-based diet improves biochemical parameters and body inflammation; body weight, sleep quality, quality of life, pain at rest as well as other symptoms of FM and their impact on health. Authors conclude that even though their findings are promising further well-designed clinical trials are needed to consolidate these dietary recommendations in FM patient.
Abstract
Fibromyalgia (FM) is a chronic non-degenerative disease characterized by the presence of multiple symptoms such as chronic pain, which negatively influence the quality of life of sufferers, most of whom are women. Currently, there is no effective treatment to limit the impact of these symptoms. The aim of this research is to review the scientific evidence on the effect of following a vegetarian or vegan diet on fibromyalgia patients. A systematic review included the original articles that answered the research question. These articles were in 2021 in the PubMed, Web of Science and Scopus databases. The research used the PRISMA (preferred reporting items for systematic reviews and meta-analyses) guidelines. No time restriction was applied, and grey literature was not included. The evaluation of the methodological quality of the articles was carried out using the following different scales: STROBE (strengthening the reporting of observational studies in epidemiology), PEDro (Physiotherapy Evidence Database), and MMAT (Mixed Methods Appraisal Tool) scales. A total of 88 studies were analyzed, of which 6 investigations were included in this systematic review (n = 4 clinical trials and n = 2 cohort studies). These investigations show significant improvements in biochemical parameters, quality of life, quality of sleep, pain at rest and general health status when following mainly plant-based dietary patterns. In conclusion, these findings are promising but interpretation of the findings is limited due to the methodological quality of the studies. Well-designed clinical trials are needed to consolidate these dietary recommendations in FM patients.

Plain language summary
A common symptom of many conditions is pain, with chronic pain being a significant cause of emotional distress and disability. Chronic pain is associated with a pro-inflammatory state. Diet interventions can be a helpful tool for the management of chronic pain and its associated inflammation. The increase of nutrient-dense, antioxidant-rich foods and the reduction of pro-inflammatory foods, as well as correcting nutrient deficiencies, all appear to have a positive effect on pain. Whilst previous research on the impact of diet therapy in chronic pain yielded varied results, the authors of this article sought to analyse the most important literature to gain more clarity and direction for future research. After a detailed introduction on the different types of pain, the article summarises the outcome of a range of dietary interventions for chronic pain management. These include calorie restriction and fasting, polyunsaturated fatty acids, low-fat plant-based diets, high protein diet, elimination diet, antioxidants and vitamins including vitamin D, fruits and fibres, prebiotics and probiotics. In the discussion, a helpful table presents the key results organised by type of pain (chronic musculoskeletal pain, chronic headache, neuropathic pain, chronic abdominal pain) and the clinical interventions that showed positive outcomes. In conclusion, diet interventions could be part of a multidisciplinary approach in the management of chronic pain. This article yields an oversight of the possible interventions to consider when supporting people with different types of chronic pain.
Abstract
Pain is one of the main problems for modern society and medicine, being the most common symptom described by almost all patients. When pain becomes chronic, the life of the patients is dramatically affected, being associated with significant emotional distress and/or functional disability. A complex biopsychosocial evaluation is necessary to better understand chronic pain, where good results can be obtained through interconnected biological, psychological, and social factors. The aim of this study was to find the most relevant articles existent in the PubMed database, one of the most comprehensive databases for medical literature, comprising dietary patterns to alleviate chronic pain. Through a combined search using the keywords "chronic pain" and "diet" limited to the last 10 years we obtained 272 results containing the types of diets used for chronic pain published in the PubMed database. Besides classical and alternative methods of treatment described in literature, it was observed that different diets are also a valid solution, due to many components with antioxidant and anti-inflammatory qualities capable to influence chronic pain and to improve the quality of life. Thirty-eight clinical studies and randomized controlled trials are analyzed, in an attempt to characterize present-day dietary patterns and interventions to alleviate chronic pain.

Plain language summary
Fibromyalgia is a syndrome with unknown cause, characterised by muscle pain and physical exhaustion and is especially common in women aged 20-55 years. Anxiety, mood disturbance and psychological disorders are also often reported. Two micronutrients found in food, which may be of benefit to fibromyalgia patients are tryptophan (TRY) and magnesium (MG). This randomised control trial aimed to determine the effects of a Mediterranean diet supplemented with TRY and MG in 22 women with fibromyalgia for 16 weeks. The results showed that supplementation improved anxiety, mood, eating disorders and body image, but did not affect sleep quality. It was concluded that Mediterranean diet supplemented with TRY and MG was of benefit to anxiety, depression and reduced eating disorders but did not affect sleep quality. This study could be used by healthcare professionals to recommend a Mediterranean diet enriched with TRY and MG to improve symptoms of depression and anxiety in women with fibromyalgia.
Abstract
Anxiety, mood disturbance, eating and sleep disorders, and dissatisfaction with body image are prevalent disorders in women with fibromyalgia. The authors of this study aimed to determine the effects of tryptophan (TRY) and magnesium-enriched (MG) Mediterranean diet on psychological variables (trait anxiety, mood state, eating disorders, self-image perception) and sleep quality in women with fibromyalgia (n = 22; 49 ± 5 years old). In this randomized, controlled trial, the participants were randomly assigned to the experimental group and the placebo group. The intervention group received a Mediterranean diet enriched with high doses of TRY and MG (60 mg of TRY and 60 mg of MG), whereas the control group received the standard Mediterranean diet. Pittsburgh Sleep Quality Questionnaire, Body Shape Questionnaire, State-Trait Anxiety Inventory (STAI), Profile of Mood States (POMS-29) Questionnaire, Eating Attitudes Test-26, and Trait Anxiety Inventory were completed before and 16 weeks after the intervention. Significant differences were observed between groups after the intervention for the mean scores of trait anxiety (p = 0.001), self-image perception (p = 0.029), mood disturbance (p = 0.001), and eating disorders (p = 0.006). This study concludes that tryptophan and magnesium-enriched Mediterranean diet reduced anxiety symptoms, mood disturbance, eating disorders, and dissatisfaction with body image but did not improve sleep quality in women with fibromyalgia.

Plain language summary
Fibromyalgia is a long-term health condition causing widespread pain and is often accompanied by other symptoms such as extreme tiredness, headaches and irritable bowel syndrome (IBS). Several different dietary approaches have shown some potential in reducing the symptoms of fibromyalgia. In this meta-analysis, researchers looked at seven previous trials that examined five different dietary approaches: low-calorie; low FODMAPs (fermentable oligo-, di-, monosaccharides and polyols); gluten-free; vegan; and a monosodium glutamate (MSG) and aspartame-free diet. Pain and function improved with the low calorie diet, a raw vegan diet and the low FODMAPs diet. Other outcomes, such as quality of life, quality of sleep, anxiety and depression and inflammation also showed a significant improvement with these interventions. However, all of the studies were of low quality, and whilst there were some promising results, there is not currently enough evidence to recommend any of these dietary approaches. More well-designed clinical trials are needed on the effects of dietary approaches on fibromyalgia symptoms.
Abstract
Fibromyalgia (FM) is a chronic non-degenerative disease, whose nutritional therapy seems controversial. This systematic review aimed to synthesize the knowledge about the effect of dietary interventions on patient-reported outcomes (PRO) and inflammation in patients with FM. Six electronic databases - PubMed, BioMed Central, Cochrane library, EMBASE, LILACS and ISI - were searched for clinical trials, in which a dietary intervention in patients with FM diagnosed was conducted. Quality of evidence assessment was measured in accordance with GRADE methodology. Seven clinical trials - 3 randomized controlled trials, 1 unrandomized clinical trial and 3 uncontrolled clinical trials were identified. Dietary approaches included gluten-free diet (n = 1), raw vegetarian diet (n = 2), low Fermentable oligo-, di- and monossacharides, alcohols and polyols (FODMAPs) diet (n = 1), hypocaloric diet (n = 2) and monosodium glutamate- and aspartame-free diet interventions (n = 1). The major PRO were pain and functional repercussion, with 5 out of 7 studies reporting an improvement. The progress in secondary outcomes was reported for fatigue (2/5 studies), sleep quality (2/3 studies), depression and anxiety (3/6 studies), quality of life (4/5 studies), gastrointestinal symptoms (1/2 studies) and inflammatory biomarkers (1/1 study). However, according to Cochrane Risk of Bias, these studies had poor statistical quality. Well-designed studies should be performed to investigate the dietary interventions effect on FM. Key messages Fibromyalgia (FM) is a chronic non-degenerative disease, whose nutritional therapy seems controversial but promising. Pain and functional repercussion in FM patients seem to improve with a hypocaloric diet, a raw vegetarian diet or a low FODMAPs diet, as much as quality of life, quality of sleep, anxiety and depression and inflammatory biomarkers. Existing studies in this subject are scarce and low quality, which does not allow conclusions to be drawn.

Plain language summary
Fibromyalgia is a long-term condition causing symptoms such as widespread pain, fatigue, trouble sleeping and problems with memory and concentration. The purpose of this study was to examine the relationships between body mass index (BMI), body composition and fibromyalgia symptoms. 73 women with fibromyalgia and 73 healthy controls, matched on weight, were included in this cross-sectional study. Women with a higher BMI had more severe symptoms of fibromyalgia. Fat mass and visceral fat were associated with poorer quality sleep. The study’s authors concluded that promoting an ideal BMI may help to reduce some of the symptoms for women with fibromyalgia.
Abstract
The link between fibromyalgia syndrome (FMS) and obesity has not been thoroughly investigated. The purpose of this study was to examine the relationships among body mass index (BMI) and body composition parameters, including fat mass, fat mass percentage, and visceral fat, as well as FMS features, such as tender point count (TPC), pain, disease activity, fatigue, sleep quality, and anxiety, in a population of FMS women and healthy controls. A total of seventy-three women with FMS and seventy-three healthy controls, matched on weight, were included in this cross-sectional study. We used a body composition analyzer to measure fat mass, fat mass percentage, and visceral fat. Tender point count (TPC) was measured by algometry pressure. The disease severity was measured with the Fibromyalgia Impact Questionnaire (FIQ-R) and self-reported global pain was evaluated with the visual analog scale (VAS). To measure the quality of sleep, fatigue, and anxiety we used the Pittsburgh Sleep Quality Questionnaire (PSQI), the Spanish version of the multidimensional fatigue inventory (MFI), and the Beck Anxiety Inventory (BAI), respectively. Of the women in this study, 38.4% and 31.5% were overweight and obese, respectively. Significant differences in FIQ-R.1 (16.82 ± 6.86 vs. 20.66 ± 4.71, p = 0.030), FIQ-R.3 (35.20 ± 89.02 vs. 40.33 ± 5.60, p = 0.033), and FIQ-R total score (63.87 ± 19.12 vs. 75.94 ± 12.25, p = 0.017) among normal-weight and overweight FMS were observed. Linear analysis regression revealed significant associations between FIQ-R.2 (β(95% CI)= 0.336, (0.027, 0.645), p = 0.034), FIQ-R.3 (β(95% CI)= 0.235, (0.017, 0.453), p = 0.035), and FIQ-R total score (β(95% CI)= 0.110, (0.010, 0.209), p = 0.032) and BMI in FMS women after adjusting for age and menopause status. Associations between sleep latency and fat mass percentage in FMS women (β(95% CI)= 1.910, (0.078, 3.742), p = 0.041) and sleep quality and visceral fat in healthy women (β(95% CI)= 2.614, (2.192, 3.036), p = 0.008) adjusted for covariates were also reported. The higher BMI values are associated with poor FIQ-R scores and overweight and obese women with FMS have higher symptom severity. The promotion of an optimal BMI might contribute to ameliorate some of the FMS symptoms.

Plain language summary
Fibromyalgia is a complex disorder, characterised by chronic widespread musculoskeletal pain, fatigue, sleep problems and depression. Conventional treatment is multidisciplinary, including medication, exercise and CBT. This randomised, single-blinded trial aimed to determine the effectiveness of regular Tai Chi practice when compared to the standard recommended exercise, aerobic training. 226 adults diagnosed with fibromyalgia were randomly assigned to either 24 weeks of supervised aerobic exercise or 12 or 24 weeks of Tai Chi classes. A standard fibromyalgia impact questionnaire was used to assess changes in pain and quality of life measures, along with patient perception of various aspects of their condition. The study found that Fibromyalgia Impact Questionnaire scores improved across all treatment groups, however the 24-week Tai Chi group saw a statistically significant greater improvement than the aerobic group. In addition, those patients on the 24-week Tai Chi programme experienced greater improvement than those on the 12-week Tai Chi programme. There was also higher attendance and fewer drop-outs in the Tai Chi groups in comparison to the aerobic exercise group. Tai Chi could therefore be considered as an alternative to aerobic exercise in a multi-disciplinary approach to fibromyalgia treatment.
Abstract
OBJECTIVES To determine the effectiveness of tai chi interventions compared with aerobic exercise, a current core standard treatment in patients with fibromyalgia, and to test whether the effectiveness of tai chi depends on its dosage or duration. DESIGN Prospective, randomized, 52 week, single blind comparative effectiveness trial. SETTING Urban tertiary care academic hospital in the United States between March 2012 and September 2016. PARTICIPANTS 226 adults with fibromyalgia (as defined by the American College of Rheumatology 1990 and 2010 criteria) were included in the intention to treat analyses: 151 were assigned to one of four tai chi groups and 75 to an aerobic exercise group. INTERVENTIONS Participants were randomly assigned to either supervised aerobic exercise (24 weeks, twice weekly) or one of four classic Yang style supervised tai chi interventions (12 or 24 weeks, once or twice weekly). Participants were followed for 52 weeks. Adherence was rigorously encouraged in person and by telephone. MAIN OUTCOME MEASURES The primary outcome was change in the revised fibromyalgia impact questionnaire (FIQR) scores at 24 weeks compared with baseline. Secondary outcomes included changes of scores in patient's global assessment, anxiety, depression, self efficacy, coping strategies, physical functional performance, functional limitation, sleep, and health related quality of life. RESULTS FIQR scores improved in all five treatment groups, but the combined tai chi groups improved statistically significantly more than the aerobic exercise group in FIQR scores at 24 weeks (difference between groups=5.5 points, 95% confidence interval 0.6 to 10.4, P=0.03) and several secondary outcomes (patient's global assessment=0.9 points, 0.3 to 1.4, P=0.005; anxiety=1.2 points, 0.3 to 2.1, P=0.006; self efficacy=1.0 points, 0.5 to 1.6, P=0.0004; and coping strategies, 2.6 points, 0.8 to 4.3, P=0.005). Tai chi treatment compared with aerobic exercise administered with the same intensity and duration (24 weeks, twice weekly) had greater benefit (between group difference in FIQR scores=16.2 points, 8.7 to 23.6, P<0.001). The groups who received tai chi for 24 weeks showed greater improvements than those who received it for 12 weeks (difference in FIQR scores=9.6 points, 2.6 to 16.6, P=0.007). There was no significant increase in benefit for groups who received tai chi twice weekly compared with once weekly. Participants attended the tai chi training sessions more often than participants attended aerobic exercise. The effects of tai chi were consistent across all instructors. No serious adverse events related to the interventions were reported. CONCLUSION Tai chi mind-body treatment results in similar or greater improvement in symptoms than aerobic exercise, the current most commonly prescribed non-drug treatment, for a variety of outcomes for patients with fibromyalgia. Longer duration of tai chi showed greater improvement. This mind-body approach may be considered a therapeutic option in the multidisciplinary management of fibromyalgia.

Plain language summary
Fibromyalgia (FM) is a chronic rheumatic disease of unknown cause which is characterized by generalized pain, stiffness, and tenderness in specific points, and is commonly associated with other symptoms including muscular stiffness, depression, non-refreshing sleep, and cognitive impairments. Ganoderma lucidum (GL, reishi) has been demonstrated to increase vital energy, stimulating the immune system, and promoting health, and to have anti-inflammatory, antioxidant, antiviral, neuroprotective, and blood pressure lowering properties. GL is rich in polyphenols and has antioxidant properties, and has been used in many Mediterranean countries. Ceratonia siliqua (CS, carob) is also rich in polyphenols and has antioxidant properties, and was used as a control in this study. The aim of this randomised, double blind, clinical trial was to evaluate the effectiveness of GL and CS to enhance physical fitness in patients with FM. Patients took either 6g GL or 6g CS daily for 6 weeks. 25 participants from the GL and 23 from the CS group completed the study. After the 6-week treatment period, a statistically significant difference in aerobic endurance was observed between both groups, with the patients in the GL group, but not those in the CS group, showing improvements. The GL group also obtained significant improvements in lower body flexibility and velocity compared with the CS group. The authors concluded that GL may be effective in improving endurance, lower body flexibility, and velocity, whilst CS seemed to be ineffective in improving physical fitness in women with FM. They discuss that no mechanism how the GL may help with physical fitness in FM patients is known and that further research is needed.
Abstract
INTRODUCTION fibromyalgia is a chronic disease characterized by generalized pain, stiffness, poor physical conditioning, non-restorative sleep and poor health-related quality of life. Ganoderma lucidum a type of mushroom that has demonstrated several benefits in different populations. Ceratonia siliqua is a natural therapy rich in antioxidants with potential benefits on health. OBJECTIVE to evaluate the effects of 6-week treatment of Ganoderma lucidum and Ceratonia siliqua on physical fitness in patients suffering from fibromyalgia. METHODS sixty-four women with fibromyalgia participated in the study. They took 6 g of Ganoderma lucidum or Ceratonia siliqua per day for 6 weeks. Different fitness tests were selected in order to evaluate functional capacity. RESULTS after the 6-week treatment period, Ganoderma lucidum significantly improved aerobic endurance, lower body flexibility, and velocity (p < .05). No significant improvement in any physical test was observed in the Ceratonia siliqua group. DISCUSSION AND CONCLUSION Ganoderma lucidum may improve physical fitness in women with fibromyalgia, whereas, Ceratonia siliqua seemed to be ineffective at increasing physical fitness. These results may indicate that Ganoderma lucidum might be a useful dietary supplement to enhance physical performance of the patients suffering from fibromyalgia. Introducción: la fibromialgia es una enfermedad crónica caracterizada por dolor crónico general, rigidez, condición física pobre, sueño no reparador y mala calidad de vida relacionada con la salud. Ganoderma lucidum es un tipo de hongo que ha demostrado tener diferentes beneficios en diversas poblaciones. La harina de algarrobo (Ceratonia siliqua) es una fuente natural de antioxidantes con potenciales beneficios para la salud. Objetivo: evaluar los efectos sobre la condición física en mujeres con fibromialgia de un tratamiento de seis semanas con Ganoderma lucidum y compararlos con los de un tratamiento con Ceratonia siliqua. Métodos: sesenta y cuatro mujeres con fibromialgia participaron en el estudio. Se hicieron dos grupos, el primer grupo tomó 6 g diarios de Ganoderma lucidum, mientras que el segundo tomó 6 g diarios de Ceratonia siliqua. Se evaluó la condición física mediante diferentes test físicos validados. Resultados: después de seis semanas de tratamiento, Ganoderma lucidum mejoró significativamente la resistencia aeróbica, la flexibilidad del miembro inferior y la velocidad (p < 0,05). Por otro lado, Ceratonia siliqua no mejoró la condición física. Discusión y conclusiones: Ganoderma lucidum puede mejorar la condición física en mujeres con fibromialgia, mientras que Ceratonia siliqua parece no ser efectivo para este propósito. Estos resultados pueden indicar que 6 g diarios de Ganoderma lucidum podrían ser un suplemento útil para mejorar la condición física en esta población.

Plain language summary
Many conditions are associated with mitochondrial dysfunction (MDF) and oxidative stress (OS). For example; some genetic diseases, aging and age-associated disorders, neurologic and psychiatric diseases, malignancies and autoimmune diseases. This review looks at the clinical trials focused on the use of mitochondrial cofactors (mitochondrial nutrients - MN) such as alpha-lipoic acid (ALA), Coenzyme Q 10 (CoQ10) and L-carnitine (CARN) which are essential in the functioning of mitochondria. Of the trials that were used in the review, 81 tested ALA, 107 tested CoQ10, 74 reports tested CARN, only 7 reports were retrieved testing double MN associations, while no report was found testing a triple MN combination. A total of 28 reports tested MN associations with “classical” antioxidants, such as antioxidant nutrients or drugs. Combinations of MN showed better outcomes than individual MN. Further studies are therefore needed.
Abstract
An extensive number of pathologies are associated with mitochondrial dysfunction (MDF) and oxidative stress (OS). Thus, mitochondrial cofactors termed "mitochondrial nutrients" (MN), such as α-lipoic acid (ALA), Coenzyme Q10 (CoQ10), and l-carnitine (CARN) (or its derivatives) have been tested in a number of clinical trials, and this review is focused on the use of MN-based clinical trials. The papers reporting on MN-based clinical trials were retrieved in MedLine up to July 2014, and evaluated for the following endpoints: (a) treated diseases; (b) dosages, number of enrolled patients and duration of treatment; (c) trial success for each MN or MN combinations as reported by authors. The reports satisfying the above endpoints included total numbers of trials and frequencies of randomized, controlled studies, i.e., 81 trials testing ALA, 107 reports testing CoQ10, and 74 reports testing CARN, while only 7 reports were retrieved testing double MN associations, while no report was found testing a triple MN combination. A total of 28 reports tested MN associations with "classical" antioxidants, such as antioxidant nutrients or drugs. Combinations of MN showed better outcomes than individual MN, suggesting forthcoming clinical studies. The criteria in study design and monitoring MN-based clinical trials are discussed.
