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

Nutrient Quality72

Magnesium malate and the folate form are favorable ingredient choices. The quality of the other named components remains uncertain.

Ingredient Transparency100

Amounts and forms are disclosed throughout the formula. That makes it straightforward to check the serving and compare ingredient sources.

Value For Money47

The magnesium offers moderate value, while the folate is less economical. Value for the other components remains uncertain, leaving a mixed picture for the combination.

Customer Satisfaction90

Customer ratings are very positive across thousands of buyers. The broad feedback supports a clear satisfaction pattern without establishing a sleep, stress or energy benefit.

Product Focus61

Magnesium and B vitamins mainly help fill nutritional gaps supporting normal body functions. The 500 mg magnesium serving does not establish greater sleep, stress or other benefits, and suitability at that amount remains uncertain.
