Free radicals are highly reactive molecules with unpaired electrons that can interact with other molecules in cells, leading to potential damage or changes.
These radicals are produced naturally in the body during metabolic processes but can also result from external factors like pollution, UV exposure, and unhealthy lifestyles.
In the context of dietary supplements and nutraceuticals, understanding free radicals is crucial because they play a significant role in oxidative stress, a condition where the balance between antioxidants and free radicals is disrupted.
This imbalance can lead to cellular damage, aging, and various chronic diseases, including cardiovascular diseases, diabetes, and cancer.
Nutraceuticals and dietary supplements often contain antioxidants, substances that can neutralize free radicals, thereby reducing oxidative stress and potentially preventing or mitigating the damage it causes.
Common antioxidants include vitamins C and E, beta-carotene, and other phytochemicals found in fruits, vegetables, and other plant-based foods. Other compounds like coenzyme Q10, flavonoids, and polyphenols also act as antioxidants and are frequently included in these supplements.
The study of free radicals and their interaction with dietary supplements is essential for developing effective strategies to manage or prevent the oxidative stress-related health issues.
By incorporating antioxidant-rich supplements or nutraceuticals, individuals can potentially enhance their body's defense against the harmful effects of free radicals.
