[noun] Malic acid is one of the main acids found in fruits (apples, berries, stone fruits, grapes and others) and is naturally produced by the human body. When consumed as part of a balanced diet, malic acid is known for its virtues for the liver and for helping the body release energy from food when the cells lack oxygen (such as during physical effort). It is also an acidity regulator and used as a preservative in food preparations.
