Since malic acid is naturally occurring and is found in many fruits that we eat safely every day, it is generally regarded as safe. There are no serious or dangerous side effects known or reported regarding malic acid in regular recommended doses, but it is still a good idea to speak with your doctor before taking any new supplements.
Reduction of Pain
For people who suffer from fibromyalgia and/or chronic fatigue syndrome, eating foods high in malic acid or supplementing with malic acid has been shown to reduce muscle pain and muscle soreness, according to the Journal of Nutritional Medicine. This reduction of pain has been noted to be increased by the addition of a magnesium supplement, along with the malic acid. Some patients with fibromyalgia have noted a relief from pain as early as within 48 hours of taking a malic acid supplement.
