What is the Difference Between Ascorbic Acid and Sodium Ascorbate?

Ascorbic acid and sodium ascorbate are both forms of Vitamin C, but they differ in their acidity levels, sources, and potential side effects. Here are the main differences between the two:

Acidity: Ascorbic acid is an organic acid, while sodium ascorbate is a mineral salt of ascorbic acid with lower acidity levels. Sodium ascorbate is considered milder and more gastrointestinal-friendly, making it a suitable option for people who have gastrointestinal problems associated with ascorbic acid.
Source: Ascorbic acid is the purest form of Vitamin C and is found in various fruits and vegetables. Sodium ascorbate, on the other hand, is a sodium salt of ascorbic acid and is produced through the reaction between equal amounts of ascorbic acid and sodium bicarbonate.
Sodium content: Sodium ascorbate contains sodium components that help lower its acidity levels and enhance its absorption and duration in the body. However, this also means that sodium ascorbate may increase sodium levels in patients with hypertension, diabetes, and kidney disease.

Both ascorbic acid and sodium ascorbate serve as antioxidants and help boost the immune system. However, due to the differences mentioned above, sodium ascorbate is often recommended for people who struggle with gastrointestinal problems or have pre-existing medical conditions that may be affected by increased sodium intake.

Comparative Table: Ascorbic Acid vs Sodium Ascorbate

Here is a table comparing the differences between ascorbic acid and sodium ascorbate:

Property	Ascorbic Acid	Sodium Ascorbate
Definition	Ascorbic acid is an organic compound that is one of the known forms of vitamin C. It is a water-soluble vitamin that helps keep our skin, hair, and bones healthy.	Sodium ascorbate is an organic sodium salt resulting from the replacement of the proton from the 3-hydroxy group of ascorbic acid by a sodium ion. It is a form of vitamin C that has sodium components that help lower its acidity.
pH Levels	Ascorbic acid is acidic.	Sodium ascorbate has a lower acidity due to the sodium content.
Absorption	Ascorbic acid may be more easily absorbed by some individuals.	Sodium ascorbate is more easily absorbed and stays longer in the body due to the sodium content.
Sodium Content	Ascorbic acid does not contain sodium.	Sodium ascorbate contains sodium, which may increase sodium levels in patients with hypertension, diabetes, and kidney disease.
Sources	Ascorbic acid is found in most fruits and vegetables.	Sodium ascorbate is a mineral salt of ascorbic acid (vitamin C).

Both ascorbic acid and sodium ascorbate are good sources of antioxidants and help boost the immune system. However, the choice between the two forms of vitamin C may depend on individual needs and pre-existing medical conditions.
