Analysis

Source Naturals provides 500 mg of green tea extract in a tablet format. It's a solid, entry-level botanical supplement that helps introduce polyphenols into your diet for general cellular support.

While it lacks standardization for EGCG, the total extract weight is substantial. It’s a very cost-effective option for long-term daily use if you aren't looking for high-intensity clinical results.

Pros

  • Great value for 120 servings
  • Simple and straightforward formula
  • Establish brand with long history
  • High capsule weight

Cons

  • Not standardized for active EGCG
  • Tablet form may be slower to digest than capsules
  • Potency may vary

Warnings

  • Best taken with food
  • Contains naturally occurring caffeine

Nutrient quality

72 High impact

A 500 mg extract weight provides foundational botanical support for general health. Potency for specific goals is unverified due to the absence of standardization for active catechins.

Ingredient transparency

85 Highest impact

Labeling clearly states the raw extract weight of the green tea leaf and identifies the calcium form. It fails to provide information on the polyphenol or EGCG yield, which is a significant transparency gap for tea extracts.

Customer satisfaction

90 Highest impact

Solid average ratings and a high review volume reflect significant consumer trust in the product's quality. User feedback consistently reports satisfaction with the product's role in their daily antioxidant routine.

Value for money

94 Highest impact

This is an extremely affordable green tea supplement on a per-serving basis. While it lacks clinical potency, it provides excellent value for those seeking simple botanical support at a low cost.

Green tea extract is rich in polyphenols like EGCG, which are known to modulate NF-kB signaling and oxidative stress. This product provides a 500 mg dose per serving, which supports foundational antioxidant status.

The lack of disclosure regarding EGCG content or caffeine levels makes it difficult to assess its therapeutic potency. It serves as a generic antioxidant option but lacks the precision of standardized extracts for targeted goals.

Green tea leaf extract is included to provide the potential cognitive benefits associated with tea polyphenols and catechins. These compounds may support neuroprotection and general metabolic health, which are indirectly linked to mental clarity.

However, the absence of standardization for active markers like epigallocatechin gallate makes it difficult to confirm the formula's actual potency. Without a known concentration of actives, the effectiveness for cognitive support is less certain compared to standardized extracts.

Green Tea leaf extract provides a source of polyphenols that may contribute to the skin's defense against UV-induced oxidative damage. This single-ingredient approach focuses on internal photo-protection to support a healthy skin appearance.

While providing a basic level of tea compounds, the lack of standardization makes its potency and catechin content uncertain. It appears well aligned for individuals seeking a foundational antioxidant supplement for general wellness.

Green Tea Extract at 500mg provides a natural source of catechins to support metabolic rate and fat oxidation. This formula offers a straightforward and cost-effective approach to botanical metabolic support.

Energy metabolism appears moderately supported by the presence of 500mg of green tea extract. However, the lack of standardization for specific active markers like EGCG makes it difficult to guarantee a therapeutic dose for a targeted metabolism boost.

Green Tea extract is included as a source of polyphenols, which may support longevity pathways such as AMPK activation and autophagy. These mechanisms appear well-aligned with goals focused on metabolic health and cellular maintenance.

However, the lack of standardization for the active EGCG content makes it difficult to determine the functional potency of the 500mg dose. The tablet format and absence of bioavailability enhancers further limit the expected impact on biological aging markers.
