Free Radicals & Your Lifespan - Immortality Series #2

Free Radicals: The Basics

Free radicals are also known as reactive oxygen species (ROS). These work hand-in-hand with oxidants, or reactive nitrogen species (RNS). Please note that “ROS/RNS” and “free radicals” will be used interchangeably in this article, but they relate to the same subject.

Wait, But… Free Radicals Can Help?

How It Contributes to Aging

So, What’s the News?

Free radicals may be bad, but they aren’t entirely bad. Still, you should always be making sure you’re finding ways to consume antioxidants and eat healthily. This puts you at a smaller risk for the overaccumulation of free radicals and, overall, will never hurt you.

Key Takeaways

  • Free radicals are also known as reactive oxygen species (ROS) and work with oxidants (RNS). They’re created from oxygen molecules with unpaired valence electrons, which causes a chain reaction.
  • Free radicals can actually be produced from exogenous (outside the body) or endogenous (inside the body) sources.
  • When there’s an overload of free radicals, oxidative stress occurs. Oxidative stress is a phenomenon that occurs in the body when there is a disproportion in neutralization and formation of free radicals.
  • Fortunately, antioxidants are made to combat ROS/RNS. They become oxidized when they destroy a free radical, which is why we must replenish them.
  • Oxidative stress plays a hand in aging. Many studies have been conducted that found a correlation between ROS/RNS and organisms’ lifespan.
  • Eating a healthy lifestyle can help your body and produce more antioxidants to combat free radicals!
