What it is
Vitamin C is a water soluble vitamin, meaning it dissolves in water and is not stored in the body for long periods. It is also known by its chemical name, ascorbic acid.
Why it's used
It is primarily used to support the immune system and help the body produce collagen, which is a structural protein that keeps skin and joints strong. It also acts as an antioxidant, which is a substance that protects cells from damage caused by unstable molecules called free radicals.
How it compares to Vitamin B Complex
While both are water soluble vitamins, they serve different primary functions in the body.

How it's made
Most commercial Vitamin C is produced through a chemical process called the Reichstein process. This involves taking a sugar, such as glucose, and using a combination of bacteria and chemical reactions to transform it into ascorbic acid. The resulting crystals are then purified and pressed into tablets or put into capsules.
What it typically costs
This supplement is generally mid range in price. This is because the raw materials used in the chemical synthesis are widely available and the manufacturing process is standardised and efficient, though it is more complex than producing simple minerals.
