Analysis

This supplement features a blend of magnesium citrate and magnesium oxide, totaling a compound weight of 1000 mg. This provides a very high amount of the mineral to help with things like bowel regularity and foundational muscle support.

While the oxide form isn't as easily absorbed systemically, the inclusion of citrate helps improve the overall utility of the blend. It is a heavy-duty option for those who have high mineral needs or struggle with consistent digestive transit.

Pros

  • Very high total mineral content
  • Good for promoting regular bowel movements
  • Popular choice with many users
  • Provides both systemic and local effects

Cons

  • High oxide content may cause loose stools
  • Exact elemental yield is not fully clear
  • May be too strong for sensitive stomachs

Warnings

  • May have a strong laxative effect
  • Take with a large meal

Nutrient quality

81 Highest impact

The blend of citrate and oxide provides both high elemental weight and moderate absorption pathways. While the dose is robust, the high oxide content may lead to localized digestive effects rather than systemic uptake.

Ingredient transparency

91 Highest impact

Labeling identifies the mineral forms used, but the exact elemental yield for each form could be more clearly split. Disclosure of the active amounts is adequate for general assessment.

Customer satisfaction

95 Highest impact

Consistently strong ratings across a massive review volume indicate high consumer satisfaction. Feedback confirms the product's effectiveness for leg cramps and sleep support.

Value for money

92 Highest impact

Moderate cost per serving paired with a high elemental mineral load offers good value. While better forms exist, the combination of citrate and oxide provides a balanced entry-level option.
