Phenolic acids are a class of plant-derived compounds well-known for their antioxidant properties. Scientific research has provided evidence supporting their use in mitigating free radical damage. Free radicals are unstable molecules that can cause oxidative stress, leading to cellular damage and contributing to the development of chronic diseases such as cancer, cardiovascular disease, and neurodegenerative disorders. Phenolic acids, such as caffeic acid, ferulic acid, and gallic acid, are abundant in fruits, vegetables, coffee, and whole grains. Laboratory and animal studies have demonstrated that these compounds can neutralize free radicals by donating electrons, thereby protecting biomolecules from oxidative damage.

Furthermore, some clinical studies have observed that diets rich in phenolic acids are associated with lower markers of oxidative stress in humans. Mechanistically, phenolic acids not only scavenge free radicals but also upregulate the body’s endogenous antioxidant defense systems (e.g., glutathione, superoxide dismutase). However, while in vitro and animal evidence is robust, more large-scale, randomized human clinical trials are needed to confirm their therapeutic efficacy and optimal dosages. Overall, the use of phenolic acids to support the body’s defense against free radical damage is scientifically justified, but the current level of evidence is moderate rather than definitive.
