Putting vitamin C or any water-soluble nutrient in liposomes can reportedly deliver as much as 90% absorption of the nutrient into the cells in our bodies.
For point of reference, intravenous vitamin C reportedly gives about 20% absorption into cells while taking high potency tablets of vitamin C reportedly gives considerably less.
So, it appears that orally-taken liposomal vitamin C works better than higher doses of injectable intravenous vitamin C at delivering vitamin C inside cells, where it does its work - and far better than vitamin C tablets.
