Why Choose the Ascorbic Acid form of Vitamin C?
Mineral ascorbates are fine forms of vitamin C but when you are really sick, the mineral ascorbates are not potent enough to accomplish the ascorbate effect. This is because the mitochondria are failing in their refueling of the free radical scavengers with electrons. The ascorbic acid carries 2 extra electrons per molecule where the mineral ascorbates seem to carry only one (plus per molecule the mineral ascorbates are heavier due to the mineral weighing more than the hydrogen the mineral replaces). There may be other reasons that we do not appreciate additionally." - Robert Cathcart, M.D.
Why Choose Foundation Approved Vitamin C?
Thank you for the tip on Trader Joe's vitamin C (as a low cost alternative.) I already use it, but YOUR vitamin C is THE best product I have found. I wasn't able to walk a few years ago because my circulatory system was shutting down. And it was your product that 'saved' me! Thank you again!!" - Kimrey, L. 2012
How Much Should I Take?
There are exceptions. A few animals must obtain some vitamin C in their diets every day because they are unable to make it. These are the guinea pig, fruit bat, several species of parrot and several high order primates, including humans.
After years of study, vitamin C expert and Nobel prize winning scientist Linus Pauling supplemented 18,000 mg of ascorbic acid.
Pauling's reasoning was that this amount matched blood levels in animals that make their own vitamin C. He adjusted for his body weight and accounted for loss in the gut during digestion.
His daily amount was divided into two equal dosages of 9,000 mg, to which he added a teaspoon of sodium bicarbonate (baking soda).
In ordinary health:The Vitamin C Foundation recommends 3000 milligrams divided into 3 equal 1 gram doses daily. (Less for children under 5 years old, adjusted for body weight.)
For optimal health and longevity:Linus Pauling recommended 6,000 mg to 18,000 mg daily in his book "How To Live Longer And Feel Better" (1986). 
During times of extreme illness:Dr. Robert Cathcart recommended using bowel tolerance to help determine the correct dosage. These dosages can exceed more than 200,000 milligrams. See: Titrating Vitamin C to Bowel Tolerance
Jaffe C-Cleanse/Calibration:We are all individuals with varying requirements for vitamin C. The Russell Jaffe Vitamin C Calibration (sometimes called Cleanse) can be used to estimate the daily need.
Powder versus Capsules
For those that find ascorbic acid powder hard to swallow, it is easy and inexpensive to make your own capsules. Check out your local health food store for generic capsules and the do-it-yourself capsule making kits.
