Product analysis

41 out of 100

Keto-Karma Burn Fat Red provides B vitamins for normal nutrient functions and green tea with limited support for specific skin and blood-vessel effects. Its complex, partly undisclosed blend makes individual contributions hard to judge.

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

Nutrient Quality32

Vitamin B5 has a favorable form. Most other preparations remain uncertain, with many unspecified forms and an undisclosed botanical blend.

Ingredient Transparency59

All listed amounts are stated, but most ingredient forms are unspecified. The botanical blend lacks an individual breakdown, and total caffeine exposure cannot be determined from the plant amounts.

Value For Money32

Several ingredients, including B5, citrulline and theanine, are relatively costly within the serving. Value for most other preparations remains uncertain.

Customer Satisfaction69

Customers are generally satisfied with their purchases. Several hundred ratings offer a useful view of satisfaction, without showing whether the supplement works.

Product Focus20

The clearest roles are nutritional support from B vitamins and limited, preparation-dependent effects from green tea and citrulline. The complex mixture and undisclosed caffeine exposure make broader benefits and stimulant suitability harder to judge.
