Sodium bicarbonate (NaHCO3) is an essential acid buffer of our body. It forms the largest alkaline buffer in our blood and ensures that our blood remains slightly alkaline (pH 7,365) by neutralizing acid waste. Sodium bicarbonate, also known as baking soda, has a purifying effect in the removal of acids.
Sodium bicarbonate is a body’s own substance. It must be sufficiently present in the body to balance the acid balance of the body. Apart from the body, sodium bicarbonate is used as an acidity regulator in foods, stabilizers, raising agents (hence the nickname baking soda) and in the medical world as an ingredient of medicines against, for example, gastric acid. Due to its use as an ingredient, sodium bicarbonate has also been assigned an E number: E500.
