Liposomal delivery enhances absorption of vitamin C into plasma and leukocytes: a double-blind, placebo-controlled, randomized trial

Performed at Texas Tech University and Shetty’s Hospital

Study Results

A randomized, double-blind, placebo-controlled study was conducted on humans to examine the bioavailability of LipoVantage® Liposomal Vitamin C vs Non-Liposomal Vitamin C. Results showed that LipoVantage® Liposomal Vitamin C was 27% MORE bioavailable when compared to Non-liposomal Vitamin C.

In the same study, 20% more LipoVantage® Liposomal Vitamin C was found in the white blood cells (leukocytes) as compared to non-liposomal vitamin C, showing the increased bioavailability of liposomal vitamin C. Furthermore, LipoVantage® Liposomal Vitamin C stayed in the white blood cells for over 24 hours vs non-liposomal Vitamin C. An increased amount of Vitamin C in the white blood cells shows that liposomal vitamin C can better reach the important immune-fighting cells of the body thereby increasing the effectiveness of Vitamin C.
