A comprehensive index of clinical studies and laboratory standards for green tea polyphenols and synergistic herbal formulations.

At ChiTea, our commitment to purity and potency is rooted in nearly three decades of expertise. This library serves as a resource for health practitioners and consumers to explore the documented benefits of green tea catechins and the rigorous testing that defines the “Chi Standard.”

1. Cardiovascular & Heart Health Research

Scientific literature has extensively documented the protective role of green tea polyphenols in heart health:

  • LDL Oxidation: Studies at the University of Scranton found that green tea is a superior antioxidant, highly effective at preventing LDL oxidation in the bloodstream. View Study.
  • Myocardial Protection: A 2004 study at the Graduate School of Medicine in Kyoto, Japan, found that green tea polyphenols protect the heart from oxidative stress and maintain function after ischemic arrest. View Study.
  • Hypertension & Hypertrophy: Research suggests EGCG prevents the development of left ventricular hypertrophy induced by pressure overload and renal hypertension. View Study.
  • Vascular Health: Researchers at Zhejiang Medical University found that green tea consumption helped reduce blood coagulation and platelet stickiness, corroborated by many other studies. View Study.

2. Metabolic Science & Weight Management

The impact of EGCG on fat oxidation and lipid absorption is supported by international research:

  • Fat Oxidation: A randomized, double-blind study confirmed that EGCG can increase fat oxidation in men, contributing to anti-obesity effects. Learn More.
  • Lipid Absorption: University of Connecticut research indicates that green tea catechins interfere with the digestion and intestinal absorption of dietary fats and cholesterol. Learn More.
  • Metabolic Homeostasis: University of Hawaii studies showed that green tea extract improved glucose levels during tolerance tests and reduced triglyceride content in liver and heart tissues. View Findings.

3. Purity Standards & Lab Certifications

We don’t just claim purity; we prove it through independent laboratory testing:

  • 0.000 Pesticide Residue: Independent lab tests (Alpha Labs) detected zero pesticide residue in ChiTea concentrate.
  • Fluoride-Free: While tea leaves naturally accumulate fluoride, ChiTea is laboratory certified to be fluoride-free.
  • 95% Polyphenol Standardization: Our extracts are certified to contain greater than 95% polyphenols and 76 mg of EGCG per 30-drop serving.

Frequently Asked Questions

How many cups of tea are in a serving of ChiTea? One 30-drop serving of Ultimate Green Tea liquid extract provides the antioxidant equivalent of 12 to 15 cups of premium brewed green tea.

Is ChiTea extract fluoride-free? Yes. Unlike traditional brewed tea, which can be high in fluoride absorbed from the soil, ChiTea is laboratory-certified to be fluoride-free.

How is ChiTea extracted without chemicals? ChiTea uses a proprietary steam-water extraction process, free of alcohol and harsh chemical solvents like hexane, preserving the full-spectrum profile of the herbs.
