EFFERVESCENT VITAMIN C TABLETS
Product
Vitamin C is one essential for the health nutrient that is found in a lot of foods,
mostly vegetable or fruits, and is sold as a supplement. An effervescent vitamin C tablet
dissolves in water, so an individual can take it orally. Most of them are orange flavored. It
has been long known that vitamin C is an antioxidant agent, reducing free oxygen radicals,
thus neutralizing them. (Pehlivan, 2017) Almost every brand mentions that Vitamin C tablets
are used for a better immune system and help with the symptoms of the common cold and
flu. (Quest Nutra Pharma; Holland & Barrett; Health Aid; Multivita) In particular, Health Aid
mentions that the tablets also may help with growth, regeneration of collagen, brain
function, healthy hair, dry skin, bleeding gums and reduce pain and swelling of joints.
(Health Aid) Effervescent vitamin C tablets may also include other minerals or vitamins, such
as zinc (Zn), magnesium (Mg) and vitamin D.

Ingredients in an effervescent tablet
The ingredients of vitamin C effervescent tablets may vary between brands, but
there are four ingredients that are always present: ascorbic acid, citric acid, sodium
bicarbonate and flavor. Also, one ingredient that most tablets contain is sorbitol.
Ascorbic acid is the chemical name of vitamin C. Ascorbic acid, as most acids, is a
water soluble molecule. The molecule is shown at Image 1 and the chemical formula is
C6H8O6. Its action will be shown with more detail later.

The key ingredients for the effervescency are citric acid and sodium bicarbonate,
which, when in solid form, do not react with each other. The instant the tablet is dropped in
the water, a reaction will start between the acid and the base, producing carbon dioxide,
thus giving the bubbly effect. The balanced reaction is 𝐶6 𝐻8 𝑂7 (𝑎𝑞) + 3𝑁𝑎𝐻𝐶𝑂3 (𝑎𝑞) →
