Darling, keeping your body toned can mean a lot! I do not know his motivations and his needs but I am of the opinion that it is better to take a single active ingredient supplement, at a time. This, to verify its effectiveness and not add to the body of useless substances but which we believe instead to be of help. Magnesium supports the nervous system , relaxes, helps the intestine and “oxygenates” the musclesalong with numerous other actions but it always depends on the type of magnesium you intend to use. Silicon is an excellent elasticizer to be used to strengthen the venous walls, also useful in case of hemorrhoids, gingivitis and to strengthen hair and nails. But, here too the result is given by the silicon form that is intended to be assumed. Wheatgrass is rich in minerals and vitamins and is recommended for convalescents or in the deficient states of the aforementioned. Collagen, on the other hand, is activated by vitamin C. I therefore recommend a diet rich in these elements combined with light baths and regular and targeted physical activity. Sincerely Cinzia Zedda naturopathic iridology reflexology
