What can excessive free radicals lead to?

Excessive free radicals can lead to damage to cells because they are highly reactive molecules that can cause oxidative stress. This stress results from an imbalance between free radicals and antioxidants in the body. When free radicals outnumber antioxidants, they can initiate a chain reaction that damages cellular components, including lipids, proteins, and DNA, ultimately leading to cell injury or death. This cellular damage is linked to a variety of diseases and aging processes.

In contrast, increased memory function, improved brain plasticity, and enhanced focus suggest beneficial effects on cognitive functions and overall brain health, which are more closely associated with a balanced antioxidant system rather than the presence of excessive free radicals. Therefore, while the body does require some free radicals for normal signaling processes, an overabundance can have harmful consequences, particularly at the cellular level.
