Você está cuidando da sua alimentação, mas os níveis de colesterol continuam altos? Talvez seja hora de revisar se sua alimentação está realmente adequada — veja os erros mais comuns que sabotam os resultados. Alguns suplementos podem ajudar, sim — mas outros prometem mais do que entregam. Neste artigo, você vai entender quais suplementos têm comprovação científica no controle dos lipídios (colesterol e triglicérides), como usá-los com segurança e quais evitar.
1. Ômega-3: bom para os triglicérides, para o colesterol talvez não
Os ácidos graxos ômega-3, encontrados em peixes como salmão, sardinha, truta e em sementes como linhaça e chia, têm ação comprovada na redução dos triglicérides. Estudos mostram que cada 1g/dia de EPA + DHA (tipos diferentes de ômega-3) reduz em média 5,9 mg/dL de triglicérides — e esse efeito é ainda maior em pessoas com níveis mais altos.
Porém, o impacto no colesterol LDL (o “ruim”) varia. Em algumas pessoas, especialmente quando se usa DHA, o LDL pode até aumentar. A boa notícia é que esse aumento pode estar relacionado a uma mudança no tipo de partícula de LDL (de pequenas e densas para maiores e menos perigosas). Ainda assim, é importante usar com acompanhamento profissional.
Dica prática: se seu triglicérides estiver alto, tente comer peixe 2x por semana ou suplementar ômega-3.
2. Arroz vermelho fermentado: pode funcionar, mas tem riscos
O arroz vermelho fermentado (Red Yeast Rice) contém monacolina K — um composto natural com estrutura idêntica a um medicamento usado para baixar o colesterol. Estudos mostram que ele reduz significativamente o colesterol total e LDL (o “ruim”), sendo uma alternativa para quem não tolera estatinas convencionais.
Porém, os suplementos vendidos no mercado têm grande variação na quantidade de monacolina e podem conter substâncias tóxicas, como a citrinina, prejudicial aos rins. A ausência de padronização e testes de qualidade torna seu uso arriscado.
Conclusão: pode até funcionar, mas é preferível usar estatinas prescritas pelo médico, com dose controlada e segurança garantida.
3. Berberina: nova aliada na redução do colesterol e triglicérides
A berberina, extraída de plantas como a cúrcuma-árvore e o barberry, reduz a absorção de colesterol no intestino, aumenta sua eliminação e regula receptores de LDL. Na dose certa, ela pode reduzir em média 25 mg/dL de colesterol total e LDL, além de baixar triglicérides.
É uma substância promissora, mas cuidado: é fundamental monitorar o uso, já que pode interagir com outros medicamentos.
4. Probióticos: um benefício discreto, mas real
Probióticos (como Lactobacillus acidophilus e Bifidobacterium lactis) podem ajudar a reduzir o colesterol LDL e total. Estudos com até 12 semanas de suplementação mostraram reduções de 6 a 8 mg/dL nos níveis de colesterol.
Alimentos fermentados como iogurtes enriquecidos com probióticos podem ser mais eficazes do que cápsulas.
É recomendado para quem busca um complemento leve e seguro. Lembre-se de escolher iogurte sem açúcar!
5. Suplementos que não funcionam (ou são arriscados)
Nem tudo que parece natural faz bem. Veja alguns suplementos que não devem ser usados para controle de colesterol:
- Chá verde e catequinas: podem ajudar, mas há risco de hepatite.
- Alho, policosanol, coco, água de coco, bergamota e resveratrol: evidências científicas inconsistentes ou ausentes.
- Selênio, cálcio, isoflavonas de soja: sem benefício comprovado nos lipídios.
Suplemento não substitui estilo de vida ou medicamento — e nem sempre é seguro!
Se você quer usar suplementos para cuidar do colesterol, escolha os que têm evidência científica (como ômega-3, berberina e probióticos), mas faça isso como parte de um plano completo, com dieta saudável, atividade física, acompanhamento profissional e, quando necessário, medicação.
E lembre-se: “natural” não é sinônimo de seguro ou eficaz. Sempre converse com seu médico antes de iniciar qualquer suplemento.
Suplementos podem ajudar, mas o pilar principal continua sendo a alimentação. Veja quais padrões alimentares têm mais respaldo científico para baixar o colesterol.
