Scientific title


Study hypothesis

Fibromyalgia (FM) is a complex, chronic condition which causes widespread pain and fatigue, as well as a variety of other symptoms that reflect an increased central hypersensitivity to pain and to multiple sensations. Despite the improved knowledge of FM, treatment is still palliative. There is evidence to support the use of antidepressants, cardiovascular exercise, cognitive behavioural therapy, patient education, or a combination of all of them. Complementary therapies are used very often, among them nutritional therapies (vitamins, ions, minerals, and others). Moreover, other treatments with ions and minerals are empirical and remain challenging.

Because there is no currently no “magic pill” for FM, treatment aims at managing FM symptoms to the greatest extent possible. In order to improve their symptoms, especially pain and fatigue, the present study was undertaken to ascertain the influence of an oral beverage solution, Recuperat-ion®; which contains carbohydrates (glucose and fructose), and ions and minerals (sodium, potassium, calcium and magnesium) to improve pain and fatigue in FM patients. Calcium plays a role in mediating muscle contraction and nerve transmission. Magnesium is required for both anaerobic and aerobic energy generation and for glycolysis, either indirectly as a part of the Magnesium-Adenosine Triphosphate (Mg-ATP) complex or directly as an enzyme activator. Sodium aids in nerve impulse conduction and muscle contraction control. In addition to calcium, potassium is important in the regulation of neuromuscular activity.

Patient information sheet




Group one: Recuperat-ion®
Group two: placebo

A 15-day washout period was required (pre-treatment period). Response to therapy was evaluated at 30, 60, 90, 120, 150, and 180 days (treatment period), and a 30-day observation period followed (post-treatment period). All patients took four sachets (diluted in 300 ml of water or fruit juice) per day distributed over the four meals. Compliance with trial medication was monitored throughout the study. Laboratory tests were performed at baseline and at 90 and 180 days.

The following was evaluated at the initial visit and at 30, 60, 90, 120, 150, and 180 days:
1. Severity of pain and fatigue (visual analogue pain rating scale)
2. Pain in tender points (digital palpation)
3. General health status and quality of life (Nottingham Health Profile)
4. Psychological well-being (Faces Scale, Hospital Anxiety and Depression Scale)

A global assessment of treatment efficacy was made by the physician and the patient at the end of the treatment period. Comparisons between the two treatments were performed using intention-to-treat-and-cure statistical methods. All statistical procedures were conducted using SPSS statistical software v10.1. This study was approved by the ethics committees of the three hospitals. All patients gave their written informed consent.
