Vitamin C (L-Ascorbic Acid) Study:
Before you buy Liposomal Vitamin C we recommend reading this Study:
- Intravenous vs Liposomal Encapsulated vs Un-encapsulated (Powder) Vitamin C Modes of Delivery & Protective Results
Summary of the findings:
This study mentions that it adopts the long accepted clinical definition of Vitamin C “bioavailability” as being the level of circulating vitamin C in Blood Plasma (p.28).
The study found that plasma vitamin C was highest in order of: Intravenous, then Liposomal and then Un-encapsulated powder (see figure 2 p.27).
But did these different delivery methods and resulting different plasma levels translate into different levels of protective properties against Oxidative Stress levels as measured on subjects put under stress tests to induce cellular oxidative damage?
Answer: No it did not.
Lipid oxidation “was prevented by all of the vitamin C treatments and was unaffected by mode of delivery.” And further “we did not anticipate a similar degree of protection from all vitamin C treatments" (p.28).
Importantly, Figure 3 on p.28 plots the results. The placebo, as would be expected (no vitamin C), did not reduce the oxidative damage, the damage increased, while the un-encapsulated (powder) reduced oxidative damage, on par if not better than the other two delivery methods.
