Analysis

The formula provides 400 mg of green tea extract and 100 mg of caffeine, which are used to support fat oxidation and focus. It also includes chromium picolinate, which helps your body manage how it uses carbohydrates and supports healthy blood sugar levels.

I like the use of BioPerine to help with nutrient absorption, though the exact EGCG content of the green tea is not specified. It fits well as a moderate energy booster for those starting a new fitness or weight management routine.

Pros

  • Liquid softgel format for easier absorption
  • Includes BioPerine to enhance botanical uptake
  • Provides 100 mg of caffeine for focused energy
  • Features 851 mg of fish oil as a delivery base

Cons

  • Does not disclose the specific EGCG level of the green tea
  • Omega-3 fatty acid levels are relatively low
  • Proprietary 'Fat Metabolizer Blend' hides specific ingredient doses

Warnings

  • Contains caffeine; monitor your intake from coffee and tea
  • Consult a professional if you have cardiovascular concerns
  • Not intended for individuals under 18 years of age

Nutrient quality

86 Highest impact

Inclusion of chromium picolinate and BioPerine indicates a focus on metabolic cofactors and bioavailability. While the green tea extract amount is clear, the specific EGCG yield is not detailed, slightly reducing its quality score.

Ingredient transparency

74 High impact

Transparency is mixed, as the main 'Fat Metabolizer Blend' is proprietary, obscuring individual herb doses. However, the amounts for primary actives like fish oil, tea extract, and caffeine are clearly stated.

Customer satisfaction

88 Highest impact

Strong ratings indicate that consumers are generally pleased with the product's effect on energy and metabolic wellness. Feedback highlights the convenience of the liquid softgel format and steady results.

Value for money

80 Highest impact

Moderate price per serving offers fair value for a formula containing both thermogenics and fish oil. The inclusion of BioPerine adds functional value by supporting nutrient uptake.
