Choosing the right Vitamin C supplement in Italy

Italy's Vitamin C supplement market sees over 40 million units sold annually, yet choosing the right form is complex. Forms include pure ascorbic acid, buffered mineral ascorbates, patented Ester-C, and liposomal Vitamin C, each with varying acidity, absorption, and cost. Natural sources like acerola offer lower concentrations with cofactors, while daily doses up to 1,000 mg are generally safe, with absorption decreasing at higher amounts.
