The Short Version
That discarded coffee pulp we toss aside might actually be a metabolic powerhouse. A new clinical trial reveals that an extract from this "waste" can nearly double LDL cholesterol reduction by disrupting intestinal absorption, turning upcycled byproduct into high-value functional nutrition.
In This Article
What we typically discard during coffee processing might actually be a functional powerhouse. A clinical trial out of Thailand suggests that an extract derived from arabica coffee pulp could play a role in managing lipid levels. While the industry has long viewed this fruit material as waste, new research indicates it may hold significant value for metabolic health.
The extract may work by disrupting cholesterol micelle formation in the intestine, making dietary cholesterol harder to absorb.
Mechanisms of absorption
The study, published in Frontiers in Nutrition, focused on participants with obesity and elevated LDL cholesterol. Over 24 weeks, those consuming a liquid supplement made from pulp-derived extract—marketed commercially as Coffogenic—saw LDL cholesterol drop 14.9%, nearly doubling the 7.7% reduction seen in the placebo group. Researchers believe the mechanism behind this change is quite specific. The extract may work by disrupting cholesterol micelle formation in the intestine, making dietary cholesterol harder to absorb. This process mimics some effects seen in prescription medications like ezetimibe, though the scale of impact remains more moderate.
Notably, while the author team declared no conflicts of interest, the study received an educational grant from Hillkoff Co., the Chiang Mai-based company that provided the extract and markets Coffogenic. Furthermore, there is a notable temporal gap in the data: the trial was conducted between November 2019 and June 2020, yet the paper was not published until nearly six years later without explanation.
Beyond simple waste reduction
This finding aligns with a broader movement toward upcycling coffee byproducts into high-value ingredients. As companies like PectCof attract investment for food applications, the focus is shifting toward the rich concentration of chlorogenic acid and other polyphenols found within the pulp. While secondary outcomes like body weight and insulin resistance showed favorable trends, the authors noted these changes were modest rather than clinically transformative. The transition of coffee pulp from compost to supplement is already underway.

Questions & Answers
How does coffee pulp extract reduce cholesterol levels?
Coffee pulp extract reduces cholesterol by disrupting the formation of cholesterol micelles within the intestine. This process makes it significantly more difficult for the body to absorb dietary cholesterol during digestion. The mechanism functions similarly to certain prescription medications like ezetimibe, though the overall impact on lipid levels is considered more moderate. By interfering with this absorption process, the extract helps manage LDL cholesterol in individuals with obesity or elevated lipid levels.
What are the benefits of using arabica coffee pulp in supplements?
Using arabica coffee pulp provides a concentrated source of chlorogenic acid and other beneficial polyphenols for metabolic health. Clinical research indicates that extracts from this material, such as Coffogenic, can help lower LDL cholesterol levels in participants with obesity. Beyond lipid management, researchers have observed favorable trends regarding insulin resistance and body weight. This process also supports the movement toward upcycling coffee industry waste into high-value functional ingredients for food applications.
What were the results of the clinical trial on Coffogenic?
Participants in the clinical trial saw a 14.9% reduction in LDL cholesterol after consuming the liquid supplement over 24 weeks. This result was nearly double the 7.7% reduction observed in the placebo group during the same period. While the study also showed positive trends regarding insulin resistance and body weight, these specific secondary outcomes were described as modest rather than clinically transformative. The trial focused specifically on individuals struggling with obesity and high cholesterol.
Why is coffee pulp being repurposed for functional food products?
Coffee pulp is being repurposed because it contains a rich concentration of polyphenols and chlorogenic acid that can support metabolic health. While the industry traditionally viewed this fruit material as waste to be composted, new research shows it has significant value as a functional powerhouse. Companies are now investing in upcycling these byproducts into high-value ingredients for the food and beverage market. This shift allows manufacturers to turn former waste into useful nutritional supplements.
