From the Guidelines
Yes, a polyphenols and chlorogenic acid (CGA) formulation is available.
Key Points
- Polyphenols, including chlorogenic acid, are found in various plant-based foods and beverages, such as green coffee, tea, and certain fruits and vegetables 1.
- Chlorogenic acid, in particular, has been shown to have anti-AGE activity and is found in high amounts in green coffee and some herbal teas 1.
- Various studies have demonstrated the potential health benefits of polyphenol-rich formulations, including reducing the risk of chronic diseases such as cardiovascular disease and certain cancers 1.
- Some food supplements and functional foods, such as those containing grape skin extracts or olive mill wastewater, have been shown to have anti-glycative properties and may be useful in reducing dietary AGE intake 1.
- Encapsulation of polyphenolic compounds, such as quercetin, may be a promising strategy to protect these compounds from degradation during digestion and enhance their bioavailability 1.
- Reformulation of foods to reduce sugar and fat content, and the addition of inhibitors from food by-products, may be another strategy to achieve sustainable health and reduce dietary AGE intake 1.
From the Research
Availability of Polyphenols and Chlorogenic Acid (CGA) Formulation
- There is evidence to suggest that CGA is widely available in plant foods, including green coffee beans, teas, certain fruits, and vegetables 2, 3, 4.
- CGA is a naturally occurring non-flavonoid polyphenol that can be found in various commercial products, such as coffee and herbal infusions 5, 6.
- The estimated dietary intake of CGA is 5 to 1000 mg/d, with daily oral doses of 13.5mg to 1200 mg showing potential health benefits 2.
- CGA has been reported to have various health benefits, including antioxidant, anti-inflammatory, antibacterial, and antiviral effects 3, 4, 6.
- However, there is no specific information available on a polyphenols and CGA formulation that is commercially available.
Potential Health Benefits of CGA
- CGA has been shown to play a role in regulating glucose and lipid metabolism, improving insulin resistance, and reducing the risk of type 2 diabetes and cardiovascular diseases 2, 4.
- CGA may also have anti-obesity properties, with potential benefits for weight management and blood pressure control 4.
- The antioxidant and anti-inflammatory effects of CGA may help mitigate oxidative stress and related adverse effects associated with an unbalanced intracellular redox state 3, 6.
Food Sources of CGA
- Green coffee beans are a rich source of CGA, with minor quantities also found in apples, eggplant, blueberries, tomatoes, strawberries, and potatoes 4.
- Commercially available coffees, including ground and instant coffees, contain varying levels of CGA, with 5-CQA present at the highest levels 5.
- Other food sources of CGA include teas, herbal infusions, and certain fruit juices, which may contribute to the estimated dietary intake of CGA 2, 6.
