Analysis

By combining aspartate, citrate, and oxide, this capsule provides 400 mg of magnesium from different angles. This approach helps ensure that at least some of the mineral is absorbed through more efficient organic pathways.

It is an incredibly affordable choice for someone who wants to support their heart health or sleep quality. With 300 capsules per bottle, it offers some of the best long-term value on the market for multi-source magnesium.

Pros

  • Amazing value with 300 capsules
  • Three different forms for absorption
  • Supports energy and heart rhythm
  • Once-daily capsule is easy to manage

Cons

  • Oxide portion is less efficient
  • Total elemental load per bottle is high

Warnings

  • Monitor for any digestive sensitivity
  • Keep away from high heat

Nutrient quality

71 High impact

Diverse mineral forms offer varied absorption, but the total elemental weight is exceptionally high. Providing 1200 mg in a single serving creates significant safety and digestive concerns.

Ingredient transparency

100 Highest impact

Identification of all three magnesium forms and their specific weights provides clear label insight. Intake guidance is standard, though high-dose warnings would be beneficial.

Customer satisfaction

92 Highest impact

Strong ratings from a very large review pool indicate widespread use and satisfaction. Positive feedback is notable given the potentially challenging elemental dosage.

Value for money

97 Highest impact

Extremely low cost per serving represents absolute market leadership for budget magnesium. Value is unmatched for those seeking maximum elemental weight for the lowest price.

Magnesium is provided as a 400 mg complex of aspartate, citrate, and oxide forms in this single-capsule supplement. While this dose may contribute to physical relaxation, the presence of magnesium oxide may lower the overall systemic absorption.

This focused mineral formula supports muscle and nervous system relaxation, which are important cofactors for restorative rest. It provides a meaningful elemental yield that may help address deficiencies that impact nightly sleep quality.

Magnesium acts as a mandatory cofactor for hundreds of enzyme systems, including those that generate and utilize ATP. This triple magnesium complex provides a very high dose intended to address deficiencies that lead to physical and mental exhaustion.

Providing 400mg per capsule ensures meaningful systemic support for cellular fuel pathways. However, the inclusion of magnesium oxide in the blend represents a lower-tier form that is less bioavailable than organic chelates.

This multi-source magnesium complex provides foundational support for free hormone levels by inhibiting sex hormone-binding globulin. Magnesium is a crucial mineral for hundreds of enzymes involved in natural hormone production and vitality.

While the 400mg dose is therapeutically relevant, the formula relies partly on poorly absorbed magnesium oxide. The use of multiple mineral forms is common, but the presence of inorganic salts reduces the overall absorption potential for systemic support.

Magnesium is a critical mineral for maintaining healthy blood pressure and a steady heart rhythm. Utilizing three different forms, including citrate and aspartate, provides a broad range of absorption pathways for this essential cardiovascular nutrient.

A total serving of 1200 mg elemental magnesium is exceptionally high and may be poorly tolerated by the digestive system. A more conservative dose of 200-400 mg is typically recommended to maximize efficacy while avoiding significant side effects.
