Its caffeine content offers antibacterial properties by disrupting bacterial cell wall synthesis. ## Health Benefits • [Antioxidant activity](/ingredients/condition/antioxidant) from chlorogenic acids (CGA) content ranging from 342.8–1079.4 mg/100 g (preliminary evidence from phytochemical analysis only) • Antibacterial properties through caffeine's inhibition of bacterial cell wall synthesis (in vitro evidence only) • [Anti-inflammatory](/ingredients/condition/inflammation) potential from phenolic compounds including caffeic acid and ferulic acid (mechanistic inference, no clinical data) • Potential anti-carcinogenic properties from CGA content (theoretical based on constituent properties) • Rich source of bioactive alkaloids including caffeine (515.6–745.9 mg/100 g) and trigonelline (453.8–645.2 mg/100 g) (composition data only, no clinical outcomes) ## Mechanism of Action Chlorogenic acids in Coffea canephora act as phenolic antioxidants by scavenging [reactive oxygen species](/ingredients/condition/antioxidant) and chelating metal ions. Caffeine inhibits bacterial growth by interfering with peptidoglycan synthesis in bacterial cell walls. The [anti-inflammatory](/ingredients/condition/inflammation) potential likely involves inhibition of cyclooxygenase and lipoxygenase pathways. ## Clinical Summary Current evidence for Coffea canephora benefits relies primarily on phytochemical analyses and in vitro studies. Chlorogenic acid content has been quantified through laboratory analysis showing significant variation between samples. Antibacterial activity has been demonstrated in laboratory conditions against various bacterial strains. Human clinical trials specifically examining robusta coffee extracts are limited, making therapeutic applications preliminary. ## Nutritional Profile Robusta coffee beans contain a distinct nutritional and phytochemical profile compared to Arabica. Macronutrients per 100g green bean: protein 10–11.5g (higher than Arabica, rich in glutamic acid, aspartic acid, and leucine), lipids 7–10g (lower fat than Arabica; lipid fraction includes diterpenes cafestol and kahweol at lower concentrations than Arabica, ~0.1–0.5mg/g), carbohydrates 38–42g (predominantly sucrose 3–7g/100g pre-roast, degraded significantly upon roasting; polysaccharides including galactomannans and arabinogalactans 40–55% of dry weight). Caffeine content is notably elevated at 2.0–2.7g/100g green bean (approximately double that of Arabica at 1.2–1.5g/100g), directly contributing to its stronger stimulant profile. Chlorogenic acids (CGAs) are the dominant bioactive compounds, present at 342.8–1079.4mg/100g, with 5-caffeoylquinolinic acid (5-CQA) as the primary isomer; Robusta consistently shows higher CGA concentrations than Arabica (7–12% vs 5.5–8% dry weight basis). Phenolic acids include caffeic acid (~50–150mg/100g green bean), ferulic acid (~10–40mg/100g), and p-coumaric acid (trace levels). Trigonelline content: 0.6–0.9g/100g (lower than Arabica's 1.0–1.2g/100g), which degrades to niacin (vitamin B3) during roasting, yielding approximately 10–40mg niacin/100g roasted coffee depending on roast degree. Minerals per 100g roasted ground coffee: potassium 1,600–2,000mg (high bioavailability in brewed form ~70–80% extraction), magnesium 50–80mg, phosphorus 140–170mg, manganese 0.5–1.2mg, copper 0.1–0.3mg. B vitamins: niacin (B3) 10–40mg/100g roasted (roast-dependent), riboflavin (B2) ~0.2mg/100g. Melanoidins (Maillard reaction products) constitute 25–30% of roasted bean dry weight and contribute [antioxidant](/ingredients/condition/antioxidant) and [prebiotic](/ingredients/condition/gut-health) properties. CGA bioavailability from brewed Robusta is estimated at 33–55% absorption in the small intestine; remaining CGAs are metabolized by colonic microbiota into hydroxycinnamic acids. Caffeine bioavailability approaches ~99% upon oral ingestion. Lipid-bound diterpenes (cafestol/kahweol) have low extraction in filtered coffee (<0.2mg/cup) but higher in unfiltered preparations (1–5mg/cup); relevant for cholesterol-modulating effects at higher intake levels. ## Dosage & Preparation No clinically studied dosage ranges are available. Phytochemical analysis shows methanolic flower extracts contain caffeine (515.6–745.9 mg/100 g), trigonelline (453.8–645.2 mg/100 g), and total CGA (342.8–1079.4 mg/100 g). Hot water infusions extract 84% CGA and 91% caffeine. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Caffeine content in Coffea canephora can cause jitteriness, [insomnia](/ingredients/condition/sleep), and increased heart rate in sensitive individuals. May interact with medications metabolized by CYP1A2 enzyme, including theophylline and certain antidepressants. Contraindicated in individuals with severe anxiety disorders or cardiac arrhythmias. Pregnant women should limit caffeine intake to under 200mg daily from all sources. ## Scientific Research No human clinical trials, RCTs, or meta-analyses were found in the research dossier. Available evidence consists solely of phytochemical composition studies and in vitro antibacterial activity assessments without human data or PubMed PMIDs. ## Historical & Cultural Context No historical context or traditional medicine uses for Coffea canephora were documented in the research sources. Modern applications focus on its bioactive compounds for potential antibacterial and [antioxidant](/ingredients/condition/antioxidant) benefits. ## Synergistic Combinations Green tea extract, L-theanine, Rhodiola rosea, Panax ginseng, Cordyceps ## Frequently Asked Questions ### What is the difference between Coffea canephora and Coffea arabica? Coffea canephora (robusta) contains 1.7-4.0% caffeine compared to arabica's 0.8-1.4%. Robusta has higher chlorogenic acid content (342.8-1079.4 mg/100g) and greater disease resistance but more bitter taste. ### How much caffeine is in Coffea canephora extract? Coffea canephora typically contains 1.7-4.0% caffeine by weight, roughly double that of arabica beans. Green coffee bean extracts can contain 20-50% chlorogenic acids with varying caffeine levels depending on processing methods. ### Can Coffea canephora help with weight loss? Chlorogenic acids in Coffea canephora may influence glucose metabolism and fat absorption in laboratory studies. However, human clinical evidence for weight loss effects specifically from robusta coffee is limited and preliminary. ### What are the side effects of Coffea canephora supplements? Common side effects include caffeine-related symptoms like jitteriness, insomnia, rapid heartbeat, and digestive upset. Higher chlorogenic acid content may cause stomach irritation in sensitive individuals, especially when taken on empty stomach. ### Is Coffea canephora safe during pregnancy? Pregnant women should limit total caffeine intake to under 200mg daily from all sources including Coffea canephora. The higher caffeine content in robusta makes portion control more critical compared to arabica coffee consumption. ### What is the chlorogenic acid content in Coffea canephora compared to other coffee species? Coffea canephora contains chlorogenic acids (CGA) ranging from 342.8–1079.4 mg/100 g, which is notably higher than Coffea arabica, making it a more potent source of this antioxidant compound. However, current data on CGA content comes from preliminary phytochemical analysis rather than standardized clinical extraction methods. The variation in CGA levels depends significantly on growing conditions, processing methods, and plant genetics within the canephora species. ### Does Coffea canephora have antibacterial or anti-inflammatory properties supported by evidence? In vitro laboratory studies suggest that caffeine in Coffea canephora may inhibit bacterial cell wall synthesis, and phenolic compounds like caffeic acid and ferulic acid have theoretical anti-inflammatory potential. However, these findings are limited to mechanistic studies and cell-based research with no clinical trials demonstrating these effects in humans. More robust research is needed to determine whether these properties translate to meaningful health benefits when consumed as a supplement. ### How does processing or extraction method affect the active compound profile of Coffea canephora supplements? Different extraction and processing methods can significantly impact the concentration of chlorogenic acids, caffeine, and phenolic compounds in Coffea canephora supplements. Standard hot water extraction, spray-drying, and cold extraction techniques each yield different phytochemical profiles, though comparative data on bioavailability between methods is limited. Consumers should look for products specifying their extraction method and standardized CGA or caffeine content to ensure consistency and potency. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
