Antocianines

Anthocyanins: Nature’s Vibrant Antioxidants for Health, Longevity & Innovation

1. What Are Anthocyanins?

Anthocyanins are water-soluble flavonoid pigments responsible for the red, purple, and blue hues in fruits, vegetables, and flowers. Structurally, they consist of an anthocyanidin backbone (e.g., cyanidin, delphinidin) bonded to sugar moieties like glucose or rutinose. These polyphenols exhibit exceptional redox activity, enabling potent free radical scavenging (ORAC values up to 40,000 μmol TE/g) and metal chelation67. Beyond their visual appeal, anthocyanins modulate critical cellular pathways—including NF-κB, Nrf2, and AMPK—linking them to anti-inflammatory, metabolic, and anticancer effects48.

3. Health Benefits, Optimal Dosage & Safety

Validated Therapeutic Effects

• Anticancer Activity:

  • Inhibits HT-29 colon cancer proliferation (IC₅₀: 1.1–6.3 mg/mL) via BAX/Bcl-2 pathway activation and VEGF suppression8

  • Induces G2/M phase arrest in hepatocellular carcinoma (SMMC-7721 cells)10

• Metabolic Health:

  • Reduces obesity: Decreases body weight by 9.6–16.6% in high-fat diet mice via butyric acid elevation4

  • Enhances insulin sensitivity: Cyanidin-3-glucoside (C3G) partitions glucose into muscles, mimicking prescription glucose-disposal agents2

• Organ Protection:

  • Lowers liver inflammation (↓ TNFα, IL-6, NF-κB)4

  • Protects erythrocytes from oxidation (635 ± 30 mg AAE/g plasma)7

• Dermatological Benefits:

  • “Oral skin cosmetics” – Blocks 85% of UV-induced skin cell death5

Dosage Recommendations

• General Wellness: 50–200 mg/day

• Therapeutic Use:

  • Metabolic support: 300 mg C3G2

  • Cancer adjuvant: 200–500 mg standardized extract810

• Safety Threshold: ≤1,000 mg/day (excess may cause GI distress)

Highest-Potency Sources

• Black goji berry extracts: 35–40% anthocyanins5

• Purple corn concentrates: 25–30% anthocyanins (cyanidin-3-glucoside dominant)8

Precaucions crítiques

• Interaccions medicamentoses: May potentiate antihypertensives/chemotherapy drugs – monitor closely.

• Purified vs. Whole-Plant: Isolated anthocyanins ↑ LDL cholesterol in hyperlipidemic models; whole extracts mitigate risks3.

• Stability Sensitivity: Degrades under light/heat – use encapsulated formats69.
