## Questions & Answers

**Q: is this the same as Liposomal C?**
A: No. 

A liposome is a spherical-shaped vesicle that is composed of one or more phospholipid bilayers, which closely resembles the structure of cell membranes. The ability of liposomes to encapsulate hydrophilic or lipophilic drugs have allowed these vesicles to become useful drug delivery systems.
In other words, Nano particles for better absorption into cell walls.

**Q: How big is the capsule? I'm looking for something easier to swallow for my elderly father.**
A: Average size. Open capsule an empty contents into water.

**Q: how much vitamin c and what form is in each capsule.**
A: It is 500mg Vit. C and I do not know the forms. Recommended by my internist.

**Q: Does this have corn?**
A: It does not mention corn on the label.
