Vitamin C powder has been shown to prevent and cure disease, plus remove or neutralize toxins which are encountered every day, in water, in our own teeth fillings, even in food products. 20 grams per day will supply 18 grams of C plus 2 grams of calcium. This is the maximum practical oral dose, of both C and calcium. 1/4 tsp = 1.25 grams of C. . Dr. Thomas Levy has written "Curing the Incurable" to lay out the medical proof of the power of Vitamin C. In the book it is told, 2 boys were caught under a crop duster while playing in a field of corn. Both received a lethal dose of parathion. One went to the local hospital and died. The second went to a Vitamin C doctor and received 100,000mg of C intravenously. He went home for supper. . Use the powder in a mouthwash to keep teeth and gums healthy, even on the skin. Take 20 grams daily. The uses are limitless, to stay healthy and young.

Calcium Ascorbate powder.

I have been using this product for quite a while and find it excellent. I have chronic Lyme disease and have been greatly helped by a protocol which involves taking high doses of pure salt and vitamin C. Many thanks for a great product which is extremely economical.

Yuk but good....

Posted by PippiDataflow on Dec 27, 2011

I take 5 to 10 grams daily of C so I´m happy with the product as it's better for me then ascorbic acid (too acid for my type) but it's pretty yuk..... I mix it with my other powders plus some lime juice to make it more palatable.
