What does it do? Malic acid is a naturally occurring compound that plays a role in the complex process of deriving ATP—the energy currency that runs the body—from food.
Although uncontrolled research had suggested that the combination of 1,200–2,400 mg per day of malic acid and 300–600 mg of magnesium for eight weeks reduced symptoms of fibromyalgia,1 double-blind evidence has shown that malic acid plus magnesium fails to help people with this condition.2
Where is it found? Malic acid is found in a wide variety of fruits and vegetables, but the richest source is apples, which is why malic acid is sometimes referred to as “apple acid.”
Malic acid has been used in connection with the following conditions (refer to the individual health concern for complete information):

and relatively consistent scientific data showing a substantial health benefit. Contradictory, insufficient, or preliminary studies
suggesting a health benefit or minimal health benefit. An herb is primarily supported by traditional use, or
the herb or supplement has little scientific support and/or minimal health benefit. |

How much is usually taken? Healthy people do not need to take malic acid as a supplement. Research has been conducted with 1,200–2,400 mg of malic acid in combination with 300–600 mg of elemental magnesium.
