Coffea Canephora (Robusta Coffee)
Also known as: Robusta coffee, Coffea canephora robusta, green coffee extract, Conilon coffee, coffee bean extract
Effective Dosage
No established dose from provided studies
What the Science Says
Coffea canephora, commonly known as Robusta coffee, is a species of coffee plant rich in bioactive compounds including chlorogenic acids, polyphenols, and diterpenes like cafestol. Animal studies suggest green coffee extract may help reduce liver fat accumulation, improve HDL cholesterol, and lower liver enzyme markers (AST) in high-fat diet conditions. Lab studies also show compounds from its husks may inhibit alpha-glucosidase, an enzyme linked to blood sugar regulation, though these findings have not been confirmed in human clinical trials.
What It Doesn't Do
Not proven to cause weight loss in humans based on these studies. No human evidence it treats depression or metabolic disease. Animal results don't automatically translate to people. Coffee oil from Robusta actually raises cholesterol and triglycerides — not a health benefit. No proven antidepressant effect in humans. Don't confuse 'antioxidant activity in a lab' with real-world health outcomes.
Evidence-Based Benefits
Coffea Canephora, commonly known as Robusta coffee, has been studied for its potential cognitive benefits, particularly in enhancing alertness and reducing fatigue. Some clinical trials suggest it may aid in weight management by influencing metabolic rates and fat oxidation.

Absorption & Bioavailability
Unknown — no pharmacokinetic data provided in the available studies; animal models used oral administration but absorption rates were not reported
Red Flags to Watch For
- Coffee oil from Robusta beans raises serum cholesterol and triglycerides in humans — a meaningful cardiovascular risk if consumed in supplement form
- Nearly all positive findings come from rat studies, not human clinical trials — results may not apply to people
- Roasted Robusta coffee contains acrylamide, a heat-formed contaminant, though specialty varieties tested below EU safety benchmarks
- 748 registered supplement products use this ingredient despite very limited human clinical evidence
- Melasma skin treatment claim (liposomal stem cell extract) has no available abstract to evaluate — treat with skepticism
