About Lactic Acid

When muscles are not provided with enough Oxygen they go into 'Oxygen Debt' and begin producing Lactic Acid which builds up in the muscles causing a stitch.

Lactic Acid is toxic in large quantities so it is transported to the liver where it is removed from the blood and detoxified by turning it back into glucose.
