Malic acid is a naturally occurring compound that plays a role in the complex process of
deriving adenosine triphosphate (ATP; the energy currency that runs the body) from food.
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):
Who is likely to be deficient?
A deficiency in humans is unlikely, since the body can produce malic acid.
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.
Are there any side effects or interactions?
Current research does not indicate any adverse effects from the use of malic acid in
moderate amounts.
At the time of writing, there were no well-known drug interactions
with malic acid.
