Product analysis

73 out of 100

Decaffeinated Mega Green Tea Extract offers tea compounds in a decaffeinated preparation, with limited support for some cholesterol-related changes. Unclear exposure to the key compounds makes it harder to judge whether the same effects apply to this serving.

AI assessment of the formula, label and price. How scoring works

Nutrient Quality40

Tea compounds are named, but the extract’s form quality remains uncertain. Unknown proportions prevent a clear view of the balance within the preparation.

Ingredient Transparency80

The extract amount and named tea compounds are disclosed. Their individual proportions are missing, so total extract weight cannot establish the exact active-compound exposure.

Value For Money100

The selected serving offers favorable value for green-tea extract. Comparing its declared EGCG content separately from total extract weight helps keep that value judgment meaningful.

Customer Satisfaction87

Customer feedback is very positive. Thousands of ratings provide a broad picture of buyer satisfaction, without establishing the claimed health effects.

Product Focus81

A single extract keeps the formula simple to follow. Several benefits are proposed, but preparation-specific and mixed findings call for cautious expectations.
