We use this powder for the Pauling/Rath therapy (megadoses of Vitamin C) for cardiovascular disease, and for overall well-being. The Carlson ascorbic acid crystals are very fine and dissolve easily in water or juice, and can be made into a Liposomal vitamin C solution. Liposomal vitamin C may in fact be better absorbed in the gut (by combining lecithin granules and ascorbic acid); I have found that this combined mixture prevents getting the ‘runs’ or stomach upset/bloating at higher dosages( >4,000mg). (Search for «Homemade Lypo C») Also, I like the fact that Carlson’s ascorbic acid is NOT made from corn. For anyone who may have a corn sensitivity or allergy, this is important. I also appreciate the fact that iHerb ships this large container to Canada via USPS to save me on shipping costs! Keep up the good work iHerb!
