Abstract(s)
Introdução: Os suplementos alimentares (SA) têm um papel importante na manutenção da saúde da população e diversos benefícios demonstrados. No entanto, a crença errónea de que estes são isentos de risco e as escassas obrigações legais requeridas para a sua entrada no mercado, têm servido de alerta para a necessidade de mais estudos. Objetivos: Reunir informação científica sobre plantas medicinais utilizadas em SA para patologias do Sistema Cardiovascular e Sistema Nervoso Central (SNC); analisar a rotulagem de SA comercializados para as mesmas patologias. Métodos: Estudo observacional descritivo transversal, com compilação da informação científica sobre plantas medicinais utilizadas em SA para patologias do Sistema Cardiovascular e SNC (Parte 1); e recolha e análise da informação presente na rotulagem de SA vendidos em Farmácias Comunitárias e Ervanárias para as mesmas patologias, sob o ponto de vista legal e científico (Parte 2). Resultados: Na parte 1 do trabalho foi compilada a informação de 58 monografias para 24 plantas medicinais. Na parte 2 do trabalho analisaram-se 76 SA. Do ponto de vista legal, a maioria dos SA analisados cumpriu as 6 menções obrigatórias na rotulagem, pela legislação portuguesa. Do ponto de vista científico, o nome científico das plantas e as precauções de uso, foram as informações mais presentes nos SA, com 93,4 e 92,1%, respetivamente. Por sua vez, as interações (17,1%), o aconselhamento (11,8%); os efeitos adversos (10,5%); e a padronização (39,5%) foram as informações menos referidas. Conclusões: Os resultados do estudo realçam a necessidade de alterações na legislação dos SA, com a inclusão obrigatória de informações que permitam aos consumidores escolher SA de forma informada e segura.
Introduction: The dietary supplements have an important role in public health and several proven benefits. However, the mistaken belief that they are risk-free and the few legal obligations required for their market entrance have warned for the need of more studies. Objectives: Gather scientific information on medicinal plants used for cardiovascular and nervous systems pathologies; analyze the label of dietary supplements marketed for the same pathologies. Methods: Cross-sectional descriptive observational study, compiling scientific information on medicinal plants used in dietary supplements for cardiovascular and nervous systems pathologies (Part 1); and collection and analysis of the information on labeling of dietary supplements marketed in community pharmacies and herbalists for the same pathologies, from a legal and scientific point of view (Part 2). Results: In part one, the information of 58 monographs of 24 medicinal plants have been compiled. In part two, 76 dietary supplements have been analyzed. On a legal aspect, most of the analyzed supplements complied with the six mandatory labeling mentions, under Portuguese law. From the scientific point of view, the plants’ scientific name and the precautions for use were the most present information in dietary supplements, with 93,4% e 92,1%, respectively. In turn, interactions (17,1%); counseling (11,8%); adverse effects (10,5%); and standardization (39,5%) were the least reported information. Conclusions: The study results highlight the need for changes in dietary supplements’ legislation, with the mandatory inclusion of information that allows consumers to choose dietary supplements in an informed and safe manner.
