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)

Thanks for your feedback!

Dual C

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.

Thanks for your feedback!

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

Thanks for your feedback!

Excellent

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

Thanks for your feedback!
