What is the best vitamin c supplement?

Lypo-Spheric C: Until recently i would have said most vitamin c is created equal, but a relatively new formulation called lypo-spheric c is much better absorbed and can cross cell membranes better. See http://www.Livonlabs.Com/ it is pricier than other forms of c, but if you are motivated you can make your own liposomal vit c at home: see http://www.Quantumbalancing.Com/liposomalc.Htm.
