Green Tea Extract Supplements: Catechins, Extract Weight and Liver Context
Green tea as a beverage and concentrated green tea extract are different exposures. Vitanox declares extract weight and total catechins separately; neither declaration automatically establishes a caffeine or EGCG amount.
Compare the exact preparation and labeled serving
The checked tablet lists 166.7 mg green tea extract containing 83.35 mg catechins, alongside rosemary, turmeric and grape seed. Keep those measures separate and do not invent a caffeine-free or exact EGCG declaration.
The amounts below reproduce the inspected manufacturer online panel. They describe labeled servings, not an individualized regimen. Confirm your selected package and review the full ingredient list and dietary attributes on the product page.

What the ingredient evidence can establish
NCCIH describes modest or inconsistent effects on selected weight and lipid measures. Beverage observations and extract trials should remain separate, and neither establishes a guaranteed weight-loss or cardiovascular-prevention result.
Catechins are a group of compounds, not a synonym for a specific EGCG quantity. The presence of other herbs in Vitanox means a green tea trial cannot verify the whole formula's outcome.

Review suitability, medicines and the whole formula
Liver injury has been reported with some concentrated green tea products, and medicine interactions can occur. Review liver history, prescriptions and current manufacturer instructions with your clinician. Beverage safety should not be transferred automatically to an extract tablet.
Ask whether the comparison concerns a beverage, a concentrated extract or a multi-herb combination. Examine actual constituents and the intended goal before selecting a product.
