A process for extracting vitamins and minerals from a first plant matter(s) is disclosed wherein the said first plant matter(s) is treated with acidic matter followed by extraction with water. Said treatment converts the water-insoluble vitamins and minerals into water-soluble forms leading to a more comprehensive extraction with better yields of the plant constituents. Suitable selection of the first and second plant matter(s) and their proportions yields an extract that is a ready-made formulation of the desired vitamins and minerals in RDA quantities. Other advantages are reduced processing times and processing steps. Extraction of guava fruits, guava leaves, holy basil leaves, lemon peels, amla fruits, annato seeds, Wrightia tinctoria, Lantana camara, bamboo shoots, mustard seeds, and curry leaves is described.
