Also known as: Arabica coffee, coffee extract, Coffea arabica

Overview

*Coffea arabica* extract is derived from the seeds of the *Coffea arabica* plant, which is one of the most widely consumed coffee species globally. It is often utilized as a dietary supplement due to its potential health benefits, primarily attributed to its high content of chlorogenic acids (CGAs), caffeine, and other bioactive compounds. Research suggests that *Coffea arabica* extract may contribute to weight management and exhibit antioxidant properties. The maturity of research on its health effects is moderate, though some high-quality systematic reviews support its benefits. The extract is commonly available in various forms, including capsules and powders, often marketed for weight loss and general health support.

Benefits

Evidence supports several benefits of *Coffea arabica* extract, particularly in weight management. A systematic review and meta-analysis indicated that green coffee extract (GCE) may help reduce body mass index (BMI) in individuals with a baseline BMI of 25 kg/m2 or higher, showing a modest effect size (weighted mean difference of -0.403 kg/m2). Additionally, the antioxidant properties of coffee extracts, including iron-chelating activities, contribute to potential health benefits. Further studies suggest broader cardiovascular health improvements linked to regular coffee consumption. Populations with higher baseline BMI may see the most significant benefits, though results take several weeks to manifest.

How it works

Chlorogenic acids in *Coffea arabica* extract are believed to influence glucose metabolism and fat absorption, potentially aiding in weight management. These compounds interact with biological pathways associated with oxidative stress, providing antioxidant benefits. Additionally, CGAs can bind to ferric ions and scavenge free radicals, enhancing cardiovascular health. The bioavailability of CGAs can vary based on individual metabolism and the form of the extract.

Side effects

*Coffea arabica* extract is generally considered safe when consumed in moderate amounts. Common side effects, seen in over 5% of users, include jitteriness, anxiety, and insomnia, mirroring typical caffeine-related reactions. Uncommon side effects (1-5%) may include stomach upset and diarrhea, while allergic reactions are rare (<1%). Caution is advised for specific population groups, such as pregnant women or individuals with caffeine sensitivity. Additionally, interactions with medications like blood thinners warrant attention, as high doses may exacerbate these effects or introduce new risks.

Dosage

The recommended dosage of *Coffea arabica* extract typically ranges from 200 to 400 mg of green coffee extract per day, with many studies utilizing doses between 400 to 800 mg for weight management purposes. While a minimum effective dose has not been well-established, effects may take several weeks to be noticeable. Timing is also important, as administration before meals may enhance weight management benefits. The maximum safe dose is not clearly defined, and excessive intake could lead to increased side effects. Factors like food intake and individual metabolism can affect absorption.
