Liposomal encapsulation is a technology commonly used in food processing and medicine. This study determines whether Double Nutri (liposomal encapsulation) increases the absorption rate for vitamin C supplementation. Subjects enrolled in this study took vitamin C without liposome; then, 14 d washout was given with liposomal process A vitamin C. After 14 d washout, the subjects took liposomal process B vitamin C (Double Nutri) was given. After taking the test sample, the vitamin C concentration in venous blood was measured from the baseline (0 h), 0.5, 1, 2, 3, 4, and 8 h. Eleven healthy subjects were recruited for three tests. The vitamin C concentration for liposomal process B vitamin C (Double Nutri) group is higher (7.26±3.52, p<0.01) than that for the liposomal process A vitamin C group (6.41±3.80, p<0.05) and for vitamin C without liposome (2.21±4.07). This shows that Double Nutri has better bioavailability and can last up in the body to 8 hours. In addition, this study shows that Double Nutri increases the half-life of vitamin C in plasma and has higher bioavailability.enAntioxidant; Bioavailability; Liposome; Vitamin C; Food Processing; ASCORBIC-ACID; PHARMACOKINETICS; NANOLIPOSOMES[SDGs]SDG3journal article10.1166/jbn.2022.3274357159012-s2.0-85132453733WOS:000815334000003https://api.elsevier.com/content/abstract/scopus_id/85132453733
