Product analysis
Goodbye Stress Berry Verbena may help ease short-term tension, though the evidence does not establish lasting stress relief.
AI assessment of the formula, label and price. How scoring works
Nutrient Quality20
The ingredient details identify L-theanine, while the listed form disclosure is incomplete. The remaining preparations are unspecified, limiting a full comparison of form quality.
Ingredient Transparency63
Ingredient amounts are disclosed, helping with serving comparisons. Unspecified preparations make it harder to compare the actual materials used.
Value For Money34
The small theanine contribution is relatively costly, while the GABA comparison is modest. The value of the remaining ingredients is uncertain, making the full formula harder to judge.
Customer Satisfaction81
Customer feedback is generally positive. A large review pool gives a broad view of satisfaction, though reviews do not establish health benefits.
Product Focus67
The clearest fit is short-term relaxation rather than lasting changes in stress or mood. The small theanine serving limits expectations, and the lemon balm amount does not establish an additional contribution.
