Amed Coffee (Coffea arabica)

Amed Coffee (Coffea arabica) is a cultivar grown in the Amed region of Bali, Indonesia, characterized by green beans containing 57.0–80.3% chlorogenic acids on a dry matter basis and 0.85–1.73% caffeine. These compounds drive its antioxidant potential and central nervous system stimulant effects via adenosine receptor antagonism and inhibition of free radical chain reactions.

Origin & History

Amed Coffee is a specific cultivar variant of Coffea arabica, the coffee plant species native to Ethiopia and South Sudan. The plant's seeds (beans) and leaves are processed through drying, grinding, or solvent extraction to obtain bioactive compounds including caffeine (0.85-1.73 g/100g), chlorogenic acids (2.80-5.42 g/100g), and trigonelline (0.80-1.08 g/100g).

Historical & Cultural Context

No traditional medicine use documented for Amed Coffee specifically. Coffea arabica is primarily noted for beverage production and sensory quality, without established ties to traditional healing systems like Ayurveda or Traditional Chinese Medicine.

Health Benefits

• No specific health benefits documented - No clinical trials found for Amed Coffee cultivar
• Potential antioxidant properties - Green beans contain 57.0-80.3% chlorogenic acids (dry matter basis), though no clinical evidence provided
• May support alertness - Contains 0.85-1.73% caffeine in green beans, but no human studies available
• Possible cosmetic applications - Leaves noted for dermato-cosmetic potential, but no clinical validation
• Chemical composition suggests bioactivity - Rich in polyphenols and diterpenes, but therapeutic effects unproven

How It Works

Caffeine (0.85–1.73% in green beans) competitively antagonizes adenosine A1 and A2A receptors in the central nervous system, reducing inhibitory neurotransmission and increasing dopamine and norepinephrine signaling to promote alertness. Chlorogenic acids, primarily 5-caffeoylquinic acid, inhibit glucose-6-phosphatase activity and scavenge reactive oxygen species by donating hydrogen atoms to free radicals, attenuating lipid peroxidation. Roasting partially degrades chlorogenic acids into caffeic acid and quinic acid, which retain partial antioxidant capacity through phenolic hydroxyl group donation.

Scientific Research

No human clinical trials, randomized controlled trials, or meta-analyses were found specifically for Amed Coffee or Coffea arabica cultivars in biomedical applications. One unspecified PubMed study comparing organic vs. conventional Coffea arabica was mentioned without PMID, study design, or outcomes.

Clinical Summary

No clinical trials have been conducted specifically on the Amed Coffee cultivar, meaning all efficacy claims are extrapolated from general Coffea arabica research. Broader arabica studies and systematic reviews suggest chlorogenic acids at doses of 120–300 mg/day may modestly reduce fasting blood glucose and blood pressure, though these findings are not cultivar-specific. The caffeine content of 0.85–1.73% per green bean weight falls within the typical arabica range, and caffeine's cognitive and ergogenic effects are well-documented across hundreds of RCTs, but direct translation to this cultivar requires caution. Overall evidence for Amed Coffee specifically is observational and compositional rather than clinical.

Nutritional Profile

Amed Coffee (Coffea arabica) green beans contain approximately 7-12% moisture, 10-13% protein (primarily non-essential amino acids including glutamic acid, aspartic acid, and leucine), 15-18% total lipids (dominated by diterpenes cafestol and kahweol, linoleic acid ~40-45% of fatty acid fraction, palmitic acid ~30-35%), and 60-65% total carbohydrates including sucrose (~6-9% dry weight), polysaccharides (arabinogalactans and mannans comprising ~50% of dry weight), and dietary fiber (~33-40% dry weight). Bioactive compounds are the most documented fraction: chlorogenic acids (primarily 5-caffeoylquinic acid) at 57.0-80.3% of dry matter basis — notably high compared to typical Arabica ranges of 5-8% in whole beans, suggesting this figure likely refers to a concentrated or specific extract fraction; caffeine content 0.85-1.73% dry weight in green beans. Roasted beans typically yield 1.2-1.5% caffeine per 100g, ~2-4mg trigonelline per gram, and reduced chlorogenic acid content (50-70% degraded during roasting, forming melanoidins and nicotinic acid/niacin at ~10-40mg/100g). Minerals present include potassium (~1600-2000mg/100g dry), magnesium (~150-200mg/100g), calcium (~100-130mg/100g), and phosphorus (~150-180mg/100g). B-vitamins include niacin (formed during roasting from trigonelline degradation, ~14-40mg/100g roasted), riboflavin (~0.2mg/100g), and trace thiamine. Bioavailability note: chlorogenic acids show 33% absorption in humans; caffeine bioavailability is near 100% via oral consumption; cafestol and kahweol are present primarily in unfiltered brew preparations and are largely removed by paper filtration. No cultivar-specific nutritional data distinguishing Amed Coffee from broader Arabica profiles is currently documented in peer-reviewed literature.

Preparation & Dosage

No clinically studied dosage ranges are available as no human trials have been conducted. Compositional data shows green beans contain caffeine (0.85-1.73 g/100g), trigonelline (0.80-1.08 g/100g), and chlorogenic acids (2.80-5.42 g/100g dry matter), but without standardization protocols. Consult a healthcare provider before starting any new supplement.

Synergy & Pairings

No synergistic ingredients identified due to lack of clinical research

Safety & Interactions

Caffeine in Amed Coffee can cause insomnia, tachycardia, anxiety, and gastrointestinal upset at intakes exceeding 400 mg/day in healthy adults, with sensitivity varying by CYP1A2 genotype. It interacts with stimulant medications (e.g., ephedrine, pseudoephedrine), anticoagulants like warfarin, and can reduce the efficacy of adenosine used in cardiac stress tests. Chlorogenic acids may modestly lower blood pressure and blood glucose, warranting caution in individuals taking antihypertensives or antidiabetic drugs due to additive hypotensive or hypoglycemic effects. Pregnant individuals are advised to limit total caffeine intake to under 200 mg/day per major health authorities, and those with arrhythmias or severe anxiety disorders should consult a clinician before regular consumption.
