7-19-2025

What is Chlorogenic Acid?

Chlorogenic Acid (CGA) is a potent polyphenol abundantly found in:

  • Green coffee beans (primary source)
  • Artichokes, strawberries, apples
  • Eucommia ulmoides leaves

Chemically, it’s an ester of caffeic and quinic acid, functioning as a key antioxidant with clinically studied metabolic benefits.

 

Top 5 Science-Backed Benefits & Mechanisms

  1. Metabolic Health & Weight Management
    • Boosts fat metabolism by modulating glucose-6-phosphatase (reduces liver glucose output)
    • Lowers blood sugar spikes post-meal (Diabetes Care, 2019)
  2. Antioxidant Powerhouse
    • Neutralizes free radicals 2x more effectively than green tea EGCG (Journal of Agricultural Food Chemistry)
  3. Cardiovascular Support
    • Reduces LDL oxidation and improves endothelial function (Hypertension Research, 2020)
  4. Neuroprotection
    • Crosses blood-brain barrier; reduces neuroinflammation markers
  5. Antimicrobial Activity
    • Effective against H. pylori, Candida, and oral pathogens

      Chlorogenic Acid Applications

 

Chlorogenic Acid vs. Green Coffee Extract

Factor Chlorogenic Acid (Purified) Green Coffee Extract
CGA Concentration 20%-50%+ (Standardized) 5%-20% (Variable)
Consistency Batch-to-batch reliability Fluctuates with crop
Applications Pharma, supplements, functional foods Basic supplements

 

Dosing Protocol & Optimal Daily Intake

 

For End Products (Capsules/Tablets):

  • Standard Dose: 120–300 mg/day (split into 2 doses)
  • Weight Management: 200–400 mg/day pre-meals
  • Functional Foods: 50–100 mg/serving (bars, shakes)

 

B2B Formulation Guidance:

1.  Solubility: Use microencapsulated CGA for beverages (oil-soluble base)  
2.  Stability: Pair with antioxidants (e.g., rosemary extract) to prevent degradation  
3.  Synergies: Combine with chromium for glucose control

Best Practice: Start with 100 mg doses → clinically effective with minimal side effects.

 

Safety & Side Effects

  • Generally Safe: EFSA/WHO-approved (ADI: ~5 mg/kg body weight)
  • Rare Side Effects:
    • Mild digestive upset (doses >400 mg)
    • Jitteriness (when combined with caffeine)
  • Contraindications:
    • Pregnancy (limited data)
    • Autoimmune disorders (theoretical immune modulation risk)
