Cacao, derived from the seeds of the Theobroma cacao tree, has garnered attention for its potential to support mitochondrial function due to its rich profile of bioactive compounds, particularly flavonoids like epicatechin and catechin. Several in vitro and animal studies have demonstrated that these compounds can influence mitochondrial biogenesis, enhance mitochondrial respiration, and reduce oxidative stress. For example, research published in Free Radical Biology and Medicine (2018) showed that cacao flavonoids improved mitochondrial function and increased antioxidant capacity in rodent models. Another study in Phytotherapy Research (2016) highlighted that epicatechin supplementation supported mitochondrial health and promoted the expression of genes involved in mitochondrial energy production.

While these findings are promising, direct clinical evidence in humans is still limited and often indirect, usually associating cacao-rich foods (like dark chocolate) with improved markers of metabolic and cardiovascular health, which are closely tied to mitochondrial function. Traditional uses of cacao focused more on mood, cardiovascular, and general tonic effects rather than explicit mitochondrial support.

In summary, there is emerging scientific evidence—mostly from preclinical studies—that cacao and its flavonoids may positively influence mitochondrial health by reducing oxidative damage and enhancing energy production. However, robust human trials specifically assessing mitochondrial outcomes are needed to confirm these effects.
