Score 88.0

A specialized, highly effective magnesium L-Threonate product for brain health, mood, and cognitive sleep benefits, with a low elemental dose.

Analysis

Swanson Magnesium L-Threonate contains Magtein, a patented form of magnesium specifically engineered to enhance brain magnesium levels. This makes it particularly effective for goals related to cognitive function, memory, mood regulation, and improving sleep quality by calming the central nervous system. However, it's important to note that the elemental magnesium content (48mg) is significantly lower than typical magnesium supplements aimed at addressing general deficiency or supporting muscle/bone health. Therefore, while excellent for its niche, it is not a primary general magnesium supplement and is considerably more expensive per milligram of elemental magnesium.

Pros
  • Contains Magnesium L-Threonate (Magtein), a premium form known for superior brain penetration.
  • Highly effective for cognitive enhancement, memory, mood support, and brain-related sleep issues.
  • Swanson is a generally reliable brand in the supplement market.
Cons
  • Very low elemental magnesium dose (48mg) means it is unsuitable for addressing general systemic magnesium deficiency.
  • Significantly more expensive per milligram of elemental magnesium compared to general magnesium supplements.
Warnings
  • Not a suitable replacement for higher-dose magnesium supplements intended for general systemic deficiency, muscle relaxation, or bone health due to its low elemental content.
