Magnésio: santo nutriente!

O magnésio é um mineral essencial para a função metabólica ideal.

O magnésio é o quarto mineral essencial mais abundante no corpo. É distribuído aproximadamente metade no osso e metade no músculo e outros tecidos moles; menos de um por cento está no sangue. 

Estudos estimam que 75% dos americanos não cumprem a dose dietética recomendada de magnésio, o que levantou preocupações sobre os efeitos da deficiência de magnésio na saúde. 

Estudos associam a deficiência de magnésio a uma série de diversas condições médicas, e a possível eficácia na suplementação em melhorar e tratar diversos quadros.

O conteúdo mineral de magnésio em fontes alimentares está diminuindo e que a depleção de magnésio foi detectada em pessoas com algumas doenças crônicas.Isso  levou a uma maior conscientização sobre a ingestão adequada de magnésio e seu potencial papel terapêutico em várias condições médicas.

Estudos mostraram a eficácia do magnésio na eclâmpsia e pré-eclâmpsia, arritmia, asma grave e enxaqueca. 

Outras áreas que mostraram resultados promissores incluem reduzir o risco de síndrome metabólica, melhorar o metabolismo da glicose e da insulina, aliviar os sintomas da dismenorreia e aliviar as cãibras nas pernas em mulheres grávidas.

O uso de magnésio para constipação e dispepsia é aceito como tratamento padrão, apesar das evidências limitadas. 

Embora seja seguro em pacientes selecionados em dosagens apropriadas, o magnésio pode causar efeitos adversos ou morte em altas dosagens. Como o magnésio é excretado por via renal, deve ser usado com cautela em pacientes com doença renal.

As fontes alimentares de magnésio incluem vegetais de folhas verdes, nozes, legumes e grãos integrais.
