Recent research has pointed to taxifolin, a flavonoid found in plants such as Siberian larch, milk thistle, and cherry wood-aged vinegars, as a potentially effective, natural supplement for weight loss. This compound, also known as dihydroquercetin, is celebrated for its powerful antioxidant properties, which help mitigate oxidative stress by neutralizing free radicals in the body.
A recent observational study published in the journal Nutrients explored the impact of daily taxifolin intake on weight loss among older adults. Conducted by a team of researchers at Japan’s National Cerebral and Cardiovascular Center, the study indicated that participants who took 300 mg of taxifolin daily lost significantly more weight than those who did not. While these findings are promising, the study’s observational nature does not establish a causal relationship, and further research is required to validate these results.
The Study and Its Findings
The study followed 62 elderly patients, with an average age of 77, who were either regular consumers of taxifolin supplements or not. Over a period of roughly six months, the taxifolin group lost an average of 1.6 kg, while the non-supplement group lost just 0.3 kg—a statistically significant difference. Moreover, none of the participants reported adverse effects from the daily supplement, suggesting that taxifolin could be a safe option for long-term use.
Along with weight loss, the researchers tracked various metabolic markers, including cholesterol levels. They found that patients taking taxifolin experienced less of a decline in their levels of high-density lipoprotein (HDL-C), often referred to as “good” cholesterol. The preservation of HDL-C levels was associated with greater weight loss in the taxifolin group, although the study did not definitively determine whether the preserved HDL-C directly contributed to weight loss or whether both outcomes were influenced by other factors.
The Role of Taxifolin in Weight Loss
Taxifolin is believed to promote weight loss through its antioxidant and anti-inflammatory properties. Preliminary studies have suggested that it may activate brown adipose tissue (brown fat), a specialized fat type that burns calories to generate heat. The activation of brown fat has been linked to enhanced calorie expenditure, which could aid in fat burning and weight management. However, these mechanisms remain speculative, and more research is needed to explore how taxifolin works in the body.
The study’s results also indicated that taxifolin intake might help mitigate obesity-related metabolic disorders, including high cholesterol and inflammation—two key risk factors for cardiovascular diseases. However, this study did not track participants’ diets, which could have influenced the results. Additionally, the lack of a placebo group means that the observed effects may be influenced by other, unaccounted-for factors.
Limitations and Future Directions
While the study’s findings are encouraging, several limitations must be addressed in future research. The observational design introduces the possibility of bias, as participants chose whether or not to take taxifolin. Furthermore, the small sample size and the absence of dietary data mean that these results should be interpreted with caution.
To better understand the weight-loss potential of taxifolin, future studies should employ randomized, placebo-controlled trials with larger sample sizes. These trials would help clarify the true effects of taxifolin on weight loss and metabolism, as well as confirm its safety for long-term use.
Conclusion
In conclusion, the study suggests that 300 mg of taxifolin taken daily for six months may support weight loss in older adults while helping to preserve healthy HDL-C levels. Although the results are promising, they must be confirmed through larger, more rigorous trials before taxifolin can be recommended as a mainstream weight management aid. If further research supports these findings, taxifolin could become a safe and natural supplement for individuals seeking to maintain a healthy weight over time.
