da più di un anno ho smesso di fumare (circa 20-22 sigarette al giorno) e subito ho avuto problemi di sonno, cioè la sera alle 23,00/23,30 circa prendo subito sonno ma alle 04,00/04,30 mi sveglio e raramente dopo qualche ora mi riaddormento. ho anche il colesterolo alto (totale 240-250)e sono ansioso. da circa un mese assumo 3 compresse al giorno da 1 mg (enervit- enerzona) di omega 3 e tra non molto poichè pratico sport con bici da corsa assumo da 2 a 6 compresso al giorno di aminoacidi (big one). quale confezione di melatonina mi consigliate di acquistare e come devo assumerla. grazie Domanda posta da: leone66 |
Utilizzi i classici 3 mg ,Key Melatonin Night , in alternativa se ha livelli di grassi elevati ,può utilizzare Key Melatonin Fluid ,sempre 3 mg . Una compressa a sera nel momento di coricarsi . Molto interessante è lo studio recentemente pubblicato dall'Università di Brescia ,riguardo i benefici riparatori che si hanno , su cellule e tessuti ,assumendo una semplice compressa di melatonina serale . L'azione è dovuta grazie alle proprietà antiossidanti e all'azione sui radicali liberi della melatonina .

Among the chemicals present in the cigarette smoke, nicotine is responsible for much of the damage; it induces marked vessel morphological dysfunction and vasoconstriction. Unfortunately, pharmacological or behavioural treatment is not useful against cigarette smoking. The purpose of this study is to test, in experimental conditions, the therapeutic ability of exogenous melatonin administered after smoking-induced vasculopathy and to evaluate the targets of its effects. Main methods: Nicotine was orally administered for 28 days. Thereafter, the rats were orally treated with melatonin for another 28 days. Vessel damage, an important vasoconstrictor peptide (endothelin-1) and the oxidative stress markers were analysed. Key findings: Nicotine treatment induced marked endothelial damage and an obvious vasoconstriction in the aorta as evaluated by an increased endothelin-1 (ET-1) expression. These alterations were correlated with a reduction of endothelial nitric oxide synthase (eNOS) and superoxide dismutase (SOD) and with increases of heat shock protein (Hsp70) and inducible nitric oxide synthase (iNOS) activities. Melatonin not only improved the impairment of endothelial-dependent relaxation, but also induced the increase of eNOS and SOD and the reduction of iNOS and Hsp70. Significance: The findings indicate that nicotine is associated with an elevated synthesis of the vasoconstrictor peptide (ET-1); it also induces a reduction of nitric oxide-mediated vasodilatation (eNOS) and promotes oxidative stress in the vessel wall. We propose that melatonin should be considered as a therapeutic intervention for smokers since it reduces vasoconstriction and oxidative stress and improves endothelial physiology. © Risposta da: Melatonina.it |
