What are antioxidants known for?

Antioxidants are primarily known for their role in neutralizing free radicals in the body. Free radicals are unstable molecules that can cause oxidative stress, leading to cellular damage and contributing to various diseases and aging processes. Antioxidants counteract this damage by donating electrons to stabilize free radicals, thereby preventing them from causing harm to cells. This protective mechanism is crucial for maintaining overall health.

The other options focus on different functions. For instance, while some nutrients can provide energy to cells, this is not a primary role of antioxidants. Similarly, supporting muscle gain and enhancing fluid balance pertain to other nutritional components and bodily mechanisms that do not align with the specific function of antioxidants. Thus, the distinction lies in the specific role of antioxidants in safeguarding cellular integrity against oxidative stress.
