What is superoxide dismutase (SOD)?

Superoxide dismutase, often abbreviated as SOD, is an enzyme naturally occurring in virtually all cells that use oxygen. It's involved in the breakdown of superoxide radicals, reactive molecules formed during normal metabolic processes. SOD converts these radicals into less reactive compounds, namely oxygen and hydrogen peroxide.

What types of SOD are there?

There are three main types of SOD in humans:

  • SOD1 (Cu/Zn-SOD):Found in the cytoplasm of cells.
  • SOD2 (Mn-SOD):Located in the mitochondria.
  • SOD3 (EC-SOD):Present in the extracellular space.

Each type has a specific function in protecting different cellular compartments from oxidative damage.

What does scientific research say about the function of SOD?

According to studies¹, SOD is involved in neutralizing superoxide radicals, which is important for maintaining cellular balance. This latter refers to a balanced state in which cells function efficiently and are not overexposed to reactive oxygen species.

Where does SOD occur naturally?

Superoxide dismutase (SOD) is present in virtually all organisms that consume oxygen. In the human body, it is found in various organs and tissues, such as the lungs, liver, and kidneys. SOD can also be found in certain plant foods, including fruits and vegetables, although concentrations vary depending on the source.

Is SOD available as a supplement?

SOD is available as a dietary supplement. It's important to note that while SOD is available in supplement form, its effectiveness and absorption can vary. Therefore, choose a high-quality supplement.
