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)

formula. It has both the water soluble and fat soluble forms of C. Most formulas just have a water soluble.

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.
