I have been using Derk and Sandy's products for years. Their Dual-C is easy to digest, gives me energy, and adds to my good health. I highly recommend Dual-C (LEX-24009)

This is the only vitamin C on the market that is both oil and water soluble. At one time I was only able to get through Life Extension Foundation but I'm glad iHerb carries this product.
Dual - C

OK if you are not allergic to corn. I prefer the powderd form that has no added ingredients.
