Vitamin C (ascorbic acid) is an essential water-soluble vitamin important for collagen synthesis, antioxidant defense, and immune function. Quantitative determination of Vitamin C in marketed products such as fruit juices, tablets, and fortified beverages is vital for quality control and regulatory compliance. Analytical techniques such as titrimetric, spectrophotometric, chromatographic, and electrochemical methods have been widely used. This review summarizes recent analytical advances, compares methods, and compiles reported Vitamin C content in different commercial products, highlighting challenges and future perspectives.
