Vitamin C - A powerful immune-support nutrient The health benefits of vitamin C are well documented.
Different forms of vitamin C Ascorbic acid Most food supplements contain vitamin C in the form of ascorbic acid. Vitamin C with bioflavonoids Bioflavonoids or flavonoids are polyphenolic compounds found in plants, and are especially plentiful in vitamin C-rich plant foods.

Yes in the early days of Dr. Klenner, Dr. And that has been the case for many years. They even often emphatically invoke Dr.
Cathcart did you? So, for oral use, NaASC as a mineral ascorbate can be great in sensitive stomachs and may have a slight GI absorption advantage over ASC but that absorption claim in and of itself has a number of mitigating factors.
The chemical formula of ascorbic acid is C 6 H 8 O 6. The molar mass is This compound can be found in citrus fruits and many other vegetables. It is advised not to cook vegetables containing this compound because it can easily be destroyed while cooking. Figure 1: Chemical Structure of Ascorbic Acid.
Ascorbic acid is a water soluble vitamin. It is available as a crystalline powder. This powder is in white to pale yellow color. It has an acidic taste and is odorless. The melting point of ascorbic acid is about o C. The pH of this acid is around pH 3. Ascorbic acid can be found in the form of ascorbate: the ionized form of ascorbic acid at pH conditions such as pH 5. When considering the stability of ascorbic acid, it is stable in open atmosphere when in the form of dry powder. But aqueous solutions of ascorbic acid are rapidly oxidized by air when exposed.
This oxidation can be catalyzed by iron and copper. Usually, sodium ascorbate is recommended for people who have gastrointestinal problems associated with ascorbic acid. Sodium ascorbate is considered mild and more abdomen friendly. However, when including sodium ascorbate in diet, it is important to keep in mind that the sodium is also being very well absorbed by the body along with the ascorbic acid.
Therefore, the dosage of intake should be carefully monitored.
