Malic acid is present in the majority of vegetables, and can be obtained by eating fruits (especially grapes, apples, and pears). This acid is one of the elements that take part in the process of extracting energy from food. Its fermentation by bacteria also enables the production of wine, particularly red wine. The absorption of malic acid is said to lower the risks of kidney stones. Malic acid is sometimes used in the treatment of fibromyalgia.
