## Overview

Colombian Supremo is a premium-grade Coffea arabica bean grown at high altitudes in Colombia, characterized by elevated concentrations of chlorogenic acids (CGA) and caffeine as its primary bioactive compounds. These compounds modulate [glucose metabolism](/ingredients/condition/weight-management) and adenosine receptor antagonism, respectively, contributing to the broader metabolic and [cognitive](/ingredients/condition/cognitive) effects associated with Arabica coffee consumption.

## Health Benefits

• No specific health benefits documented for Colombian Supremo cultivar - research dossier contains no clinical trials
• General coffee benefits may apply based on broader Coffea arabica research (not cultivar-specific)
• Type 2 diabetes risk reduction noted in general coffee meta-analysis (PMID 28628481, n>1 million) but not specific to Colombian Supremo
• [Cardiovascular](/ingredients/condition/heart-health) benefits mentioned for generic coffee (PMID 30158048) but not tested for this cultivar
• No evidence quality can be assigned as no Colombian Supremo-specific studies exist

## Mechanism of Action

Caffeine in Colombian Supremo acts as a competitive antagonist at adenosine A1 and A2A receptors, increasing [dopamine](/ingredients/condition/mood)rgic and noradrenergic neurotransmission to enhance alertness and reduce perceived fatigue. Chlorogenic acids, particularly 5-caffeoylquinic acid, inhibit glucose-6-phosphatase and slow intestinal glucose absorption, thereby attenuating postprandial [blood glucose](/ingredients/condition/weight-management) spikes. Diterpenes such as cafestol and kahweol modulate bile acid metabolism and exhibit [anti-inflammatory](/ingredients/condition/inflammation) activity via NF-κB pathway inhibition.

## Clinical Summary

No cultivar-specific clinical trials exist for Colombian Supremo; evidence is extrapolated from broader Coffea arabica and general coffee research. A 2014 meta-analysis of 28 prospective studies (PMID 28619997) found that 3–4 cups of coffee daily was associated with approximately a 25% reduction in type 2 diabetes risk, attributed largely to chlorogenic acid content. Separate meta-analyses have linked regular Arabica coffee consumption to modest reductions in all-cause mortality and [cardiovascular](/ingredients/condition/heart-health) disease risk, though effect sizes vary by preparation method and individual [metabolism](/ingredients/condition/weight-management). The evidence base is observational in nature, limiting causal inference and making direct application to Colombian Supremo specifically premature.

## Nutritional Profile

Colombian Supremo is a grade designation (screen size 17+) of Coffea arabica grown in Colombia, not a distinct cultivar per se, but a quality/size classification typically comprising Caturra, Castillo, Colombia, and Typica varieties. Nutritional and phytochemical data below reflect brewed Colombian Supremo Arabica coffee (per 240 mL/8 fl oz standard brew, approximately 10 g ground coffee extracted): **Macronutrients:** Calories ~2–5 kcal; protein ~0.3 g; total fat ~0.05 g; carbohydrates ~0.0–0.7 g; essentially zero fiber in brewed form (though spent grounds retain ~35% insoluble dietary fiber by dry weight). **Caffeine:** 80–120 mg per 8 fl oz (Arabica range; Colombian Supremo typically mid-range ~95 mg owing to larger bean size and medium roast preference). **Chlorogenic acids (CGAs):** Major bioactive class; total CGA content in green Colombian Supremo beans ~6.0–7.5 g/100 g dry weight. Dominant species: 5-O-caffeoylquinic acid (5-CQA, ~45–55% of total CGAs), 3-CQA, 4-CQA, 3,5-diCQA, 4,5-diCQA, and feruloylquinic acids. Brewed cup delivers approximately 70–200 mg total CGAs depending on roast degree (light > dark). Bioavailability: ~33% absorbed in small intestine; remainder metabolized by colonic microbiota to caffeic acid, dihydrocaffeic acid, and ferulic acid. **Trigonelline:** Green bean ~0.8–1.1 g/100 g; brewed cup ~40–65 mg. Partially converted to niacin (vitamin B3) during roasting (~0.5–1.0 mg nicotinic acid generated per cup at medium roast). **Diterpenes (cafestol & kahweol):** Present in coffee oil at ~0.5–1.2% of green bean weight. Cafestol ~2–6 mg and kahweol ~2–5 mg per 100 mL in unfiltered preparations; paper-filtered coffee retains <0.1 mg each per cup. Kahweol is notably higher in Arabica than Robusta (Robusta has near-zero kahweol). **Melanoidins:** Formed via Maillard reaction during roasting; constitute ~25% of dry weight of medium-roast brewed extract. Contribute [antioxidant](/ingredients/condition/antioxidant), prebiotic, and metal-chelating properties. Not individually quantified in standard nutrition panels. **Minerals (per 240 mL brewed):** Potassium ~116 mg (~2.5% DV); magnesium ~7–12 mg (~2–3% DV); phosphorus ~7 mg; manganese ~0.05 mg; chromium ~0.5–1.0 µg; trace amounts of calcium (~5 mg), sodium (~5 mg), zinc, iron, and copper. Polyphenol-mineral interactions may reduce iron bioavailability when consumed with meals (up to 39% inhibition of non-heme iron absorption). **Vitamins:** Niacin (B3) ~0.5–1.0 mg (from trigonelline degradation + inherent content); riboflavin (B2) ~0.18 mg (~14% DV); pantothenic acid (B5) ~0.6 mg (~12% DV); trace thiamine (B1) and folate. **Other bioactive compounds:** Caffeic acid ~1–5 mg/cup; ferulic acid ~1–3 mg/cup; p-coumaric acid (trace); N-methylpyridinium (NMP, formed during roasting) ~1–5 mg/cup — associated with reduced gastric acid secretion. **Volatile aroma compounds:** >800 identified across roasted coffee; Colombian Supremo is noted for relatively high concentrations of 2-furfurylthiol, 2-methylbutanal, and 3-methylbutanal contributing to its characteristically smooth, nutty, caramel profile. **Bioavailability notes:** Caffeine is nearly 100% bioavailable with Tmax ~30–60 min. CGA bioavailability is moderate (~33%) with significant inter-individual variation based on [gut microbiome](/ingredients/condition/gut-health) composition. Diterpene absorption is high (~70–100%) from unfiltered brews. Melanoidin bioavailability is low systemically but high for colonic fermentation (prebiotic effect). Overall antioxidant capacity (ORAC): ~2,500–3,000 µmol TE per 240 mL brewed cup, making it one of the highest antioxidant-delivering beverages per serving in the Western diet.

## Dosage & Preparation

No clinically studied dosage ranges exist for Colombian Supremo in extract, powder, or standardized forms, as it is primarily a beverage cultivar without biomedical standardization. Consult a healthcare provider before starting any new supplement.

## Safety & Drug Interactions

Colombian Supremo, like all Coffea arabica preparations, carries risks associated with caffeine intake, including anxiety, [insomnia](/ingredients/condition/sleep), tachycardia, and elevated [blood pressure](/ingredients/condition/heart-health) at doses exceeding 400 mg caffeine per day in healthy adults. It may potentiate the effects of stimulant medications and interfere with adenosine-based therapies; it can also reduce the absorption of certain medications including bisphosphonates and some antibiotics when consumed simultaneously. Chlorogenic acid content may enhance the hypoglycemic effect of antidiabetic medications, warranting [blood glucose](/ingredients/condition/weight-management) monitoring in diabetic patients. Pregnant individuals are advised to limit total caffeine intake to under 200 mg per day per WHO guidelines, as higher intake is associated with increased risk of low birth weight.

## Scientific Research

The research dossier reveals no human clinical trials, RCTs, or meta-analyses specific to Colombian Supremo coffee. While general coffee research exists (PMID 28628481 for diabetes risk reduction in over 1 million subjects; PMID 30158048 for [cardiovascular](/ingredients/condition/heart-health) benefits), none differentiate Colombian Supremo from generic Coffea arabica varieties.

## Historical & Cultural Context

Colombian Supremo lacks documented historical use in traditional medicine systems. The research indicates it has been cultivated for modern culinary purposes since the 1960s rather than for medicinal applications in indigenous or folk medicine.

## Synergistic Combinations

## Frequently Asked Questions

### What makes Colombian Supremo different from other coffee varieties?

Colombian Supremo refers to the largest screen-size grade (screen 17–18) of Colombian Coffea arabica beans, grown primarily in high-altitude regions such as Huila and Nariño above 1,500 meters. This elevation promotes slower bean maturation, resulting in denser beans with higher concentrations of chlorogenic acids and a more complex aromatic profile compared to lower-altitude Arabica grades. However, no peer-reviewed studies have quantified whether its bioactive compound levels differ significantly from other Colombian Arabica grades.

### Does Colombian Supremo coffee help with weight loss?

There is no cultivar-specific evidence supporting weight loss from Colombian Supremo. General Coffea arabica research suggests caffeine increases basal metabolic rate by approximately 3–11% and enhances lipolysis via inhibition of phosphodiesterase enzymes, raising intracellular cAMP levels. Chlorogenic acids may also modestly reduce fat absorption, but these effects are documented in broader coffee populations, not specifically in Colombian Supremo drinkers.

### How much caffeine is in Colombian Supremo coffee?

Colombian Supremo beans typically contain approximately 1.2–1.5% caffeine by dry weight, consistent with standard Coffea arabica ranges, which is lower than Coffea canephora (Robusta) at 2.2–2.7%. An 8-ounce brewed cup yields roughly 80–120 mg of caffeine depending on grind size, brew time, and water temperature. No published laboratory analyses specifically isolating Colombian Supremo caffeine content from other Arabica grades are currently available.

### Can Colombian Supremo coffee reduce the risk of type 2 diabetes?

Evidence for type 2 diabetes risk reduction comes from large-scale observational research on general coffee consumption, not Colombian Supremo specifically. A meta-analysis of 28 prospective cohort studies found that consuming 3–4 cups of coffee daily was associated with a ~25% lower risk of type 2 diabetes, with chlorogenic acids implicated in inhibiting glucose-6-phosphatase and slowing intestinal glucose uptake. These findings cannot be directly attributed to Colombian Supremo without cultivar-specific clinical data.

### Is Colombian Supremo coffee safe to drink during pregnancy?

Colombian Supremo is generally considered safe in limited quantities during pregnancy, provided total daily caffeine intake remains below 200 mg, as recommended by the World Health Organization and American College of Obstetricians and Gynecologists. Exceeding this threshold has been associated in observational studies with increased risk of fetal growth restriction and low birth weight. Pregnant individuals should also be aware that chlorogenic acids may affect iron absorption, which is a critical nutrient during pregnancy, and should consult a healthcare provider for personalized guidance.

### What is the optimal brewing temperature and time for Colombian Supremo coffee to maximize caffeine extraction?

Colombian Supremo coffee is best brewed with water between 195–205°F (90–96°C) for 4–6 minutes to achieve optimal caffeine extraction and flavor profile. Water that is too hot can over-extract bitter compounds, while cooler water may result in incomplete caffeine release. The specific bean size and density of Colombian Supremo varieties may require slight adjustments to standard brewing times compared to lighter roasts.

### Does Colombian Supremo coffee contain different levels of chlorogenic acid compared to other Arabica cultivars?

While all Coffea arabica varieties contain chlorogenic acid and polyphenols associated with antioxidant activity, Colombian Supremo cultivars are not documented to have significantly different chlorogenic acid concentrations than other arabica types in clinical literature. Chlorogenic acid content in coffee is more heavily influenced by growing altitude, soil conditions, and processing methods than by cultivar alone. Colombian coffees grown at high altitudes (1,200–2,200 meters) may naturally contain higher antioxidant levels due to environmental factors rather than cultivar-specific genetics.

### Are there quality grading standards that distinguish Colombian Supremo from other Colombian coffee grades?

Colombian Supremo is defined by the Colombian National Federation of Coffee Growers (FNC) as beans with a screen size of 18 and above, meaning the beans measure at least 7/64 of an inch in diameter. This grading standard ensures consistency in bean size and density, which correlates with more uniform flavor extraction and caffeine content compared to lower-grade Colombian coffees. Supremo grade is primarily a physical specification rather than an indicator of health benefits or chemical composition differences.
