Jablum ## Overview Jablum Coffee is a premium Jamaican Blue Mountain Coffea arabica cultivar containing approximately 1.2% caffeine by weight, which acts as an adenosine receptor antagonist to promote alertness and reduce perceived fatigue. Unlike robusta varieties, its lower chlorogenic acid bitterness and distinct bean morphology are prized for sensory quality rather than documented therapeutic applications. ## Health Benefits • No clinical health benefits documented - research focuses solely on agricultural characteristics • Contains approximately 1.2% caffeine by weight (no therapeutic studies provided) • Flavor profile described as superior to robusta (no health implications studied) • Bean size and shape characteristics documented (no biomedical relevance established) • Growing conditions and altitude preferences noted (no clinical significance demonstrated) ## Mechanism of Action Caffeine, the primary bioactive alkaloid in Jablum Coffee at roughly 1.2% dry weight, competitively blocks A1 and A2A adenosine receptors in the central nervous system, preventing adenosine-mediated inhibition of [dopamine](/ingredients/condition/mood) and norepinephrine signaling. This disinhibition elevates cyclic AMP via reduced phosphodiesterase activity and promotes catecholamine release, producing stimulant effects. Chlorogenic acids present in arabica varieties also transiently inhibit glucose-6-phosphatase and modulate GLP-1 secretion, though no specific studies on Jablum's chlorogenic acid profile have been published. ## Clinical Summary No clinical trials have been conducted specifically on Jablum Coffee or the Jamaican Blue Mountain arabica cultivar; available research addresses its agricultural and organoleptic characteristics rather than human health outcomes. General Coffea arabica research suggests caffeine at doses of 3–6 mg/kg body weight improves [cognitive performance](/ingredients/condition/cognitive), reaction time, and endurance exercise capacity in randomized controlled trials with sample sizes ranging from 20 to 200 participants. Chlorogenic acids from arabica coffee have shown modest fasting glucose reductions (approximately 5–10 mg/dL) in short-term trials, but these findings cannot be extrapolated to Jablum specifically without cultivar-level phytochemical data. The overall evidence for Jablum as a distinct therapeutic agent is absent; any attributed benefits derive from general arabica coffee literature. ## Nutritional Profile Jablum Coffee (Coffea arabica, Jamaica Blue Mountain cultivar) shares the general nutritional composition of high-grade arabica coffee beans. Raw green beans contain approximately 10-13% protein (including free amino acids such as glutamic acid, aspartic acid, and leucine), 15-18% total lipids (dominated by diterpenes cafestol and kahweol at approximately 0.2-0.8% of dry weight, linoleic acid comprising ~40% of fatty acid fraction), and 60-65% carbohydrates (primarily sucrose at 6-9% in green beans, largely degraded during roasting; polysaccharides including galactomannans and arabinogalactans at ~50% dry weight). Caffeine content is documented at approximately 1.2% by dry weight, consistent with arabica species range (0.9-1.4%), notably lower than robusta (~2.7%). Chlorogenic acids (primarily 5-caffeoylquinic acid) are present at 5.5-8% in green beans, reducing to 1.5-3% post-roasting due to thermal degradation. Trigonelline is present at approximately 0.6-1.2% (precursor to niacin/vitamin B3 upon roasting). Roasted brew (per 240ml serving) yields approximately 2-5mg niacin, trace potassium (~116mg), magnesium (~7mg), and manganese (~0.05mg). Bioavailability note: diterpenes cafestol and kahweol are largely retained in unfiltered preparations; paper filtration removes >90% of these compounds. [Antioxidant](/ingredients/condition/antioxidant) capacity (DPPH assay) is consistent with high-altitude arabica beans, though no Jablum-specific ORAC or FRAP values have been independently published. ## Dosage & Preparation No clinically studied dosage ranges available in the provided research. Consult a healthcare provider before starting any new supplement. ## Safety & Drug Interactions Caffeine from Jablum Coffee can cause tachycardia, anxiety, [insomnia](/ingredients/condition/sleep), and gastrointestinal upset at intakes above 400 mg/day in healthy adults, the upper limit recognized by the European Food Safety Authority. It inhibits CYP1A2 substrates and can potentiate sympathomimetic drugs including pseudoephedrine and certain SSRIs, while reducing the efficacy of adenosine-based medications such as regadenoson. Pregnant individuals should limit total caffeine intake to under 200 mg/day due to associations with reduced fetal birth weight at higher exposures. Those with cardiac arrhythmias, severe hypertension, anxiety disorders, or peptic ulcer disease should use caffeine-containing products cautiously and consult a physician. ## Scientific Research No clinical trials, RCTs, or meta-analyses were found in the provided research. The available data consists entirely of botanical and agricultural descriptions without any PMIDs or medical literature citations. ## Historical & Cultural Context No traditional medicinal use or historical therapeutic applications documented in the provided research. Information limited to commercial cultivation practices and flavor characteristics. ## Synergistic Combinations No synergistic ingredients documented in research ## Frequently Asked Questions ### What makes Jablum Coffee different from regular arabica coffee? Jablum is a trademarked brand of Jamaican Blue Mountain Coffea arabica grown at elevations above 910 meters in the Blue Mountains of Jamaica, a geography that produces a slower-ripening bean with a milder flavor and lower perceived bitterness compared to other arabica origins. Its caffeine content of approximately 1.2% by dry weight is typical for arabica, which is roughly half the caffeine concentration found in Coffea canephora (robusta). No unique phytochemical profile distinguishing Jablum from other Blue Mountain arabica lots has been published in peer-reviewed literature. ### How much caffeine is in Jablum Coffee? Jablum Coffee contains approximately 1.2% caffeine by dry bean weight, consistent with Coffea arabica species averages that range from 0.9% to 1.4%. A standard 8-ounce brewed cup prepared from arabica beans typically delivers 80–120 mg of caffeine depending on grind size, brew time, and water temperature. This is meaningfully lower than robusta-based coffees, which average 1.7–2.5% caffeine by weight. ### Are there any proven health benefits of Jablum Coffee? No clinical studies have investigated Jablum Coffee specifically for health benefits; available documentation focuses on its agricultural origin, bean morphology, and cup quality scores. General arabica coffee research associates moderate consumption (3–5 cups/day) with reduced risk of type 2 diabetes and Parkinson's disease in large epidemiological cohorts, mechanisms attributed to caffeine's adenosine receptor antagonism and chlorogenic acids' modulation of hepatic glucose metabolism. These associations cannot be attributed to Jablum as a distinct cultivar without targeted research. ### Can Jablum Coffee interact with medications? Caffeine in Jablum Coffee is metabolized primarily by the hepatic enzyme CYP1A2, and its consumption can reduce clearance of medications that share this pathway, including clozapine, theophylline, and certain antidepressants, potentially elevating their plasma concentrations. Caffeine also antagonizes adenosine receptors, which can diminish the effectiveness of adenosine-receptor agonist drugs used in cardiac stress testing such as regadenoson or adenosine itself. Individuals taking monoamine oxidase inhibitors (MAOIs) or stimulant medications should be particularly cautious due to additive sympathomimetic effects. ### Is Jablum Coffee safe during pregnancy? Jablum Coffee contains caffeine, and current guidelines from the World Health Organization and American College of Obstetricians and Gynecologists recommend limiting total caffeine intake to no more than 200 mg per day during pregnancy. Caffeine crosses the placenta and the fetal liver has limited CYP1A2 activity to metabolize it, leading to prolonged fetal exposure; intakes above 200–300 mg/day have been associated with increased risk of low birth weight and miscarriage in observational studies. One to two cups of Jablum or any arabica coffee per day would generally remain within the recommended limit, but individual tolerance and total dietary caffeine sources should be accounted for. ### What is the caffeine content of Jablum Coffee compared to other arabica varieties? Jablum Coffee contains approximately 1.2% caffeine by weight, which is typical for arabica coffee varieties. While this caffeine concentration is lower than robusta beans, it remains consistent with most specialty arabica cultivars grown at similar altitudes. The caffeine content per cup will depend on brewing method and serving size rather than the inherent properties of the Jablum variety itself. ### Where is Jablum Coffee grown and why does location matter? Jablum Coffee is primarily cultivated in Jamaica, specifically in the Blue Mountains region, where specific altitude and climate conditions optimize bean development. The high-altitude growing conditions and volcanic soil of this region contribute to the distinctive bean characteristics and flavor profile. These agricultural conditions are essential to the Jablum identity, though they do not alter the nutritional or caffeine composition compared to arabica grown elsewhere. ### How does Jablum Coffee's flavor profile compare to other arabica cultivars? Jablum Coffee is recognized for a superior flavor profile compared to robusta varieties, with characteristics that reflect its high-altitude Jamaican terroir. The beans are valued by specialty coffee enthusiasts for their distinctive taste rather than for any unique nutritional or bioactive properties. Flavor preference is subjective and does not indicate enhanced health benefits or supplemental value compared to other arabica cultivars. --- *Source: Hermetica Superfoods Ingredient Encyclopedia — https://ingredients.hermeticasuperfoods.com* *License: CC BY-NC-SA 4.0 — Attribution required.
