Anthocyanins are natural pigments found in various fruits and vegetables, particularly berries, red cabbage, and purple sweet potatoes. Their use in the context of aging prevention is primarily supported by scientific evidence, though the majority of research is preclinical or based on observational studies in humans. Anthocyanins exhibit potent antioxidant and anti-inflammatory properties, which are theorized to mitigate cellular damage caused by oxidative stress—a key factor in the aging process.

Several animal and in vitro studies have demonstrated that anthocyanin-rich extracts can reduce markers of oxidative stress, improve mitochondrial function, and modulate signaling pathways associated with aging, such as the Nrf2 and NF-κB pathways. Some human epidemiological studies have found associations between higher anthocyanin intake and improved cognitive function, reduced risk of cardiovascular disease, and better metabolic health outcomes in older adults. For example, regular consumption of anthocyanin-rich foods is linked to slower cognitive decline and reduced inflammation.

However, direct clinical trials specifically targeting anthocyanins for the prevention of aging or age-related diseases are limited, and most evidence is indirect, focusing on risk factors or biomarkers rather than aging itself. Thus, while the scientific rationale is strong and supported by mechanistic and population studies, definitive clinical evidence is still emerging, justifying a moderate evidence rating.
