A real-world evidence study evaluating consumer experience of Supradyn Recharge or Supradyn Magnesium and Potassium during demanding periods.

Background: Challenging periods and/or mild micronutrient deficiencies may result in a lack of energy and general fatigue, frequently occurring in the general population. Supradyn Recharge and Supradyn Magnesium and Potassium (Mg/K) are multimineral/vitamin supplements formulated to ensure adequate daily intake of micronutrients. We conducted an observational study addressing consumption behaviour, reasons for intake, frequency of intake, and consumer experiences, satisfaction and characteristics under real-life conditions. Methods: This was a retrospective, observational study carried out with two computer-aided web quantitative interviews. Results: A total of 606 respondents (almost equally split between men and women; median age 40 years) completed the questionnaires. The majority indicated having a family, a job and a good level of education; they stated to be long-time and daily users, reporting an average daily intake of 6 days a week. More than 90% of consumers claimed they were satisfied, would use the products again and recommend them; over two-thirds felt the value for money was good. Supradyn Recharge has been mainly used to support lifestyle change and mental resilience, seasonal changes, and post-illness recovery. Supradyn Mg/K has been used to sustain or regain energy levels during hot weather or physical activity and as a support against stress. Users claimed a positive impact on quality of life. Conclusion: Overall, the perception of benefit by consumers was extremely positive as reflected in their consumption behaviour, the majority of whom stated to be long-time users and daily consumers, with an average daily intake of 6 days for both products. These data complement and add up to the results of Supradyn clinical trials.

Potential mental and physical benefits of supplementation with a high-dose, B-complex multivitamin/mineral supplement: What is the evidence?

INTRODUCTION: Objective: to perform a systematic literature review to examine the effects of high-dose, B-complex multivitamin/mineral supplementation on physical, mental, and energy outcomes in healthy and 'at-risk' (suboptimal nutritional status/subclinical symptoms at baseline) adult populations. Methods: PubMed was searched for relevant randomized controlled trials until January 2020. Results: overall, 136 publications were identified. In the seven randomised, double-blind, placebo-controlled studies considered eligible for inclusion, supplementation in healthy populations predominantly showed improvements in perceived stress, physical stamina, concentration, and general mental health, and significant reductions in anxiety and improvements in self-reported vigour. However, not all of these outcomes were significant, and statistical correction for multiple outcomes was not commonly employed. Studies investigating brain mapping following supplementation indicated increased functional activity in brain regions related to processing of attention, executive control, and working memory during cognitive tasks. Conclusions: while there is certainly a need for further studies on the neurocognitive and physical benefits of micronutrient supplementation, this review provides generally supportive evidence for the benefits of a high-dose, B-complex multivitamin/mineral supplement in healthy and at-risk populations in terms of physical, mental, and energy outcomes.

INTRODUCCIÓN: Objetivo: realizar una revisión sistemática de la literatura para valorar los efectos de la administración de suplementos multivitamínicos/minerales del complejo B en dosis altas sobre los resultados físicos, mentales y energéticos en poblaciones adultas sanas y en situaciones especiales de riesgo (estado nutricional subóptimo/síntomas subclínicos al inicio del estudio). Métodos: se realizaron búsquedas en PubMed de ensayos controlados aleatorios relevantes hasta enero 2020. Resultados: en total se identificaron 136 publicaciones. En los siete estudios aleatorizados, doble ciego y controlados con placebo considerados elegibles para la inclusión, la suplementación en poblaciones sanas mostró predominantemente mejoras en la percepción del estrés, la resistencia física, la concentración y la salud mental general, así como una reducción significativa de la ansiedad y mejoras en la vitalidad según la autoevaluación de los participantes. Sin embargo, no todos estos resultados fueron significativos y la corrección estadística para múltiples resultados no se empleó habitualmente. Los estudios sobre el mapeo cerebral después de la suplementación, indicaron un aumento de la actividad funcional en las regiones del cerebro relacionadas con el procesamiento de la atención, el control ejecutivo y la memoria de trabajo durante tareas cognitivas. Conclusiones: si bien ciertamente existe la necesidad de realizar más estudios sobre los beneficios neurocognitivos y físicos de la suplementación con micronutrientes, esta revisión proporciona evidencia en general sobre los beneficios de un suplemento multivitamínico/mineral del complejo B en dosis altas, en poblaciones sanas y en situaciones de riesgo, en términos de resultados físicos, mentales y energéticos.

Benefits of micronutrient supplementation on nutritional status, energy metabolism, and subjective wellbeing.

INTRODUCTION: The human body, particularly the brain, requires energy, stored in the form of adenosine triphosphate. Energy metabolism during cellular respiration is dependent on the presence of multiple micronutrients, which act as essential components, coenzymes, or precursors at every stage. An adequate supply of multiple micronutrients is vital for efficient energy production. However, micronutrient intakes below the recommended dietary allowance are common, even in industrialized countries. Intakes of vitamins A, D, E, folate, iron, zinc, and selenium are suboptimal across all age groups. Suboptimal micronutrient levels have been shown to contribute to low energy levels, physical and mental fatigue, and impaired cognitive performance and wellbeing - symptoms frequently present in the general population. When supplemented in combination in well-conducted trials, multiple micronutrients ± coenzyme Q10 reduced oxidative stress in chronic fatigue syndrome; in healthy people they increased cerebral blood-flow hemodynamic response, energy expenditure, and fat oxidation; reduced mental and physical fatigue; improved the speed and accuracy of cognitive function during demanding tasks; and reduced stress. The results from these clinical trials suggest that even in industrialized countries, where adults might be assumed to have a healthy, balanced diet, there is a rationale to supplement with multiple micronutrients, including coenzyme Q10, to improve nutritional status, support energy metabolism, and improve subjective wellbeing.

INTRODUCCIÓN: El cuerpo humano, particularmente el cerebro, requiere energía, almacenada en forma de adenosina trifosfato. El metabolismo de la energía durante la respiración celular depende de la presencia de múltiples micronutrientes, que actúan como componentes esenciales, coenzimas o precursores en cada etapa. Un aporte adecuado de múltiples micronutrientes es vital para una producción eficiente de energía. Sin embargo, la ingesta de micronutrientes inferior a la recomendada es frecuente, incluso en los países industrializados. Las ingestas de vitaminas A, D, E, folato, hierro, zinc y selenio son subóptimas en todos los grupos de edad. Se ha demostrado que las situaciones subóptimas en relación con diversos micronutrientes contribuyen a tener niveles bajos de energía, fatiga física y mental, y deterioro del rendimiento cognitivo y el bienestar, síntomas presentes a menudo en la población general. Sin embargo, cuando se suplementa en ensayos bien controlados, con una combinación de diversos micronutrientes ± coenzima Q10, se constata una reducción del estrés oxidativo en el síndrome de fatiga crónica y, en las personas sanas, se observa un aumento de la respuesta hemodinámica del flujo sanguíneo cerebral, el gasto energético y la oxidación de la grasa; una reducción de la fatiga mental y física; una mejora de la velocidad y la precisión de la función cognitiva durante la realización de tareas exigentes, y una reducción del estrés. Los resultados de estos ensayos clínicos sugieren que, incluso en los países industrializados, donde se podría suponer que los adultos tienen una dieta saludable y equilibrada, hay motivos para complementarla con múltiples micronutrientes, incluida la coenzima Q10, con el fin de mejorar el estado nutricional, respaldar el metabolismo energético y mejorar el bienestar subjetivo.
