The Short Answer
Andean Black Corn (Zea mays L.) contains cyanidin-3-glucoside at 283.91 mg/100g and pelargonidin-3-O-glucoside at 39.57 mg/100g as primary anthocyanins. These compounds reduce inflammation by downregulating NF-κB pathways and upregulating AMPK for metabolic regulation.

resilience by neutralizing free radicals and protecting cellular integrity.
Origin & History
Natural habitat
Andean Black Corn (Zea mays L. ssp. mays) is an ancient landrace of maize originating from the high-altitude valleys of the Andes, particularly Peru and Bolivia. Revered for its striking deep purple color, this superfood is exceptionally rich in anthocyanins and other potent phytochemicals. It offers significant benefits for cardiovascular function, metabolic regulation, and antioxidant protection.
“Revered by the Inca and other Andean cultures, Andean Black Corn was a cornerstone for strength, vitality, and ceremonial renewal. It was traditionally incorporated into medicinal brews for liver support, inflammation reduction, and energy restoration, embodying deep cultural and healing significance.”Traditional Medicine
Scientific Research
Research consistently highlights Andean Black Corn's rich anthocyanin content and its significant benefits for cardiovascular function, metabolic regulation, and antioxidant protection. Studies demonstrate its role in improving endothelial health, enhancing glucose metabolism, and supporting a healthy gut microbiome. Its neuroprotective and vision-supporting properties are also under active investigation.
Preparation & Dosage
Traditional preparation
Common Forms
Whole kernels, flour, or concentrated extract.
Traditional Preparation
Historically prepared as porridge and "chicha morada," a detoxifying beverage with spices and citrus.
Dosage (Whole Food)
1–2 servings of kernels or flour daily.
Dosage (Extract)
500–1000 mg of extract daily for antioxidant and cardiovascular benefits
Nutritional Profile
- Resistant Starch & Dietary Fiber: Support gut microbiome health and digestive regularity.
- Vitamin C: Provides antioxidant support and immune function.
- Minerals: Magnesium, potassium, and phosphorus support metabolic and cellular functions.
- Anthocyanins (Cyanidin-3-glucoside): Potent antioxidant and anti-inflammatory pigments.
- Polyphenols (Ellagic acid, Gallic acid): Contribute to antioxidant and cardioprotective effects.
- Flavonoids (Quercetin, Rutin): Enhance antioxidant activity and vascular health.
- Carotenoids (Lutein, Zeaxanthin): Support vision health and provide antioxidant protection.
How It Works
Mechanism of Action
Cyanidin-3-glucoside and pelargonidin-3-O-glucoside stabilize free radicals and downregulate NF-κB pathways, reducing inflammatory cytokines TNF-α and IL-6. AMPK upregulation enhances cellular energy metabolism and intestinal barrier function. Gut bacteria metabolize anthocyanins into short-chain fatty acids like butyrate.
Clinical Evidence
Evidence is limited to animal studies, with no published human clinical trials available. In chicken embryo models, 5% and 15% black corn soluble extract significantly reduced IL-6 and TNF-α levels (p < 0.05) while upregulating AMPK and CDX2. Highland purple corn kernels demonstrated α-amylase inhibition correlated with phenolic content (r = 0.9099 at 50mg dose) and achieved 70.79% DPPH radical scavenging. Current evidence requires human clinical validation.
Safety & Interactions
No specific safety concerns, contraindications, or drug interactions are reported in available research. Animal studies show anti-inflammatory benefits without documented adverse effects. High polyphenol intake may theoretically affect iron absorption, though this remains unconfirmed for Andean Black Corn. Pregnant and breastfeeding women should consult healthcare providers due to lack of safety data.

Frequently Asked Questions
What is the main anthocyanin compound in Andean Black Corn?
Cyanidin-3-glucoside is the primary anthocyanin at 283.91 mg/100g, followed by pelargonidin-3-O-glucoside at 39.57 mg/100g. These compounds provide the deep purple color and antioxidant properties.
How does Andean Black Corn reduce inflammation?
The anthocyanins downregulate NF-κB inflammatory pathways, significantly reducing cytokines TNF-α and IL-6 as demonstrated in animal studies. They also upregulate AMPK for improved cellular energy metabolism.
Are there any clinical trials on Andean Black Corn?
No human clinical trials have been published to date. Current evidence comes from animal and in vitro studies showing anti-inflammatory and antioxidant effects.
What other beneficial compounds are found in Andean Black Corn?
Beyond anthocyanins, it contains phenolic acids like p-coumaric and caffeic acid, flavonoids including kaempferol and quercetin. Total phenolic content reaches 555 mg GAE/100g.
Can Andean Black Corn help with blood sugar control?
Animal studies show α-amylase inhibition correlated with phenolic content (r = 0.9099), suggesting potential blood sugar benefits. However, human trials are needed to confirm glucose metabolism effects.
What is the difference between Andean Black Corn and regular purple corn supplements?
Andean Black Corn is a specific landrace variety from the Andes with higher anthocyanin concentrations and a unique phytochemical profile compared to commercial purple corn varieties. Andean Black Corn contains elevated levels of resistant starch and specific polyphenol compounds that make it particularly effective for gut microbiome support and metabolic regulation. While both are anthocyanin-rich, Andean Black Corn's genetic heritage and growing conditions in high-altitude environments contribute to superior bioactive compound density.
How much Andean Black Corn should I take daily for cardiovascular and cognitive benefits?
Most research on Andean Black Corn extracts suggests effective dosing ranges from 500–1,500 mg of standardized anthocyanin extract daily, though whole-food forms may require higher quantities. The optimal dose depends on the supplement form—concentrated extracts deliver higher anthocyanin levels per serving than whole grain powders. Consistent daily intake is more important than occasional high doses, as anthocyanins work through sustained dietary exposure to support endothelial function and neuroprotection.
Is Andean Black Corn safe to take with blood pressure or diabetes medications?
Andean Black Corn is generally safe alongside most common medications, but its blood pressure-regulating and glucose-metabolism-enhancing properties mean those on antihypertensive or antidiabetic medications should inform their healthcare provider. The ingredient's insulin-sensitizing effects could theoretically potentiate diabetes medications, potentially requiring dose adjustments monitored by a physician. No serious adverse interactions have been documented, but professional medical oversight is recommended for individuals on prescription medications affecting cardiovascular or metabolic function.
