AI assessment of the formula, label and price. How scoring works
Nutrient Quality35
Most ingredient forms are named, but their quality cannot be judged fully from the available information. Iodine and tyrosine remain unspecified, limiting closer comparison of those ingredients.
Ingredient Transparency91
The listed amounts and most forms are disclosed, making much of the formula easy to compare. Iodine and tyrosine forms are not specified.
Value For Money34
Tyrosine offers weak value for the amount supplied, while iodine is more moderately priced. Most other ingredient comparisons remain uncertain, so there is little basis for a confident value judgment on the whole formula.
Customer Satisfaction76
Customer ratings are very favorable within a relatively modest review base. They show satisfaction without establishing an effect on energy or thyroid function.
Product Focus50
The clearest supported purpose is nutritional support relevant to energy. Ashwagandha and tyrosine have more limited roles that depend on the circumstances of fatigue.
