Malic acid is a commonly used ingredient in various preworkout supplements to help athletes improve their endurance during strenuous exercise.

It is a chemical that is found in various fruits, fermented fruits, and wines with medicinal properties and other industrial uses.

Some food manufacturers use it for flavoring; cosmetic companies use it to regulate the acidity of their products.

In a medicinal capacity, malic acid is used to treat dry mouth, fibromyalgia, skin conditions, and fatigue — which interests us from a fitness perspective.

Supplement companies often pair Malic Acid with L-Citrulline to form Citrulline Malate, but some insiders believe that this is the way to drive down production costs.

According to WebMD, malic acid is “involved in the Krebs cycle. This is a process the body uses to make energy. Malic acid is sour and acidic. This helps to clear away dead skin cells when applied to the skin. Its sourness also helps to make more saliva to help with dry mouth.”

Malic acid has the following medicinal usages:

  • Clearing up acne
  • Attacking warts
  • Improving skin quality
  • Diminishing the pain of fibromyalgia in conjunction with magnesium
  • Reducing fatigue
  • Quelling heartburn
