Product analysis

47 out of 100

Magnesium 500 mg can help fill a magnesium gap and support normal mineral balance. Undisclosed magnesium proportions and botanical blend contents make the combination harder to assess.

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

Nutrient Quality28

The magnesium combines forms with different absorption potential, but their proportions are undisclosed. Unidentified botanical blend contents and missing amino-acid forms add uncertainty.

Ingredient Transparency58

Amounts are listed, but only magnesium’s forms are identified. Their proportions and the botanical blend’s individual contents are omitted, leaving the complete mixture unclear.

Value For Money41

Magnesium offers moderate value, while arginine is costly for the amount supplied. Glutamine’s contribution remains uncertain, limiting confidence in the complete formula’s value.

Customer Satisfaction92

Customer feedback is generally very positive across a substantial review base. Satisfaction does not establish effectiveness or safety.

Product Focus37

Magnesium provides the clearest nutritional role when intake is low, with less consistent support for blood-pressure and stress outcomes. The large serving and mixed forms do not establish extra benefit, while the unidentified botanical blend limits assessment of the complete combination.
