AI assessment of the formula, label and price. How scoring works
Nutrient Quality24
The tyrosine form is not specified, limiting direct source comparison. Calcium is named as dicalcium phosphate, but its comparative quality remains unresolved.
Ingredient Transparency81
Both ingredient amounts are stated, making serving comparisons easier. The tyrosine entry lacks the form detail provided for calcium.
Value For Money72
The cost is favorable for the declared tyrosine amount. Calcium value remains uncertain because a usable comparison is unavailable.
Customer Satisfaction89
Buyer ratings are strongly favorable. The large rating pool gives a broad view of satisfaction without proving a mental-performance benefit.
Product Focus64
The clearest supported use concerns demanding situations involving acute stress or sleep loss. The short ingredient list keeps that purpose relatively focused.
