if you are looking for high level of natural vitamin C, choosen Acerola (malphigia glabra : 4.5% ascorbic acid 16.000 to 172.000 ppm) or even better camu-camu (myrciara dubia : 500.000 ppm). To compare orange is 500 to 4000 ppm.
Moreover these vegetal extracts (when done correctly) are high in magnesium and other minerals
