Analysis

The 250 mg elemental amount is meaningful for normal muscle, nerve, energy, bone, and cardiovascular functions. A single-mineral tablet keeps the formulation focused.

The label does not identify whether the magnesium comes from oxide, citrate, glycinate, or another compound. That missing form is crucial because absorption and bowel effects vary substantially among magnesium sources.

The product may suit users prioritizing a low-cost one-tablet amount, but form uncertainty makes it hard to match to a specific goal. A clearly labeled compound would provide more dependable systemic or digestive use.

Who is it for
  • Adults seeking basic magnesium
  • One-tablet users
  • People able to verify the magnesium form elsewhere on the label
Best for
  • Basic mineral intake after form verification
  • General magnesium support
  • Simple single-active supplementation

Pros

  • Useful elemental amount
  • One tablet per serving
  • Single-mineral focus
  • Long serving supply

Cons

  • Magnesium compound is not disclosed
  • Absorption cannot be assessed
  • Digestive effect is unpredictable
  • No supporting cofactors

Warnings

  • Confirm the magnesium form before use if digestive tolerance or systemic absorption matters.
  • The 250 mg amount may cause loose stools depending on the undisclosed compound.
  • Impaired kidney function requires clinician guidance for magnesium supplementation.

Nutrient quality

73 High impact

The elemental amount is useful for routine supplementation. Missing compound information leaves absorption quality uncertain.

.

Ingredient transparency

81 Highest impact

The elemental amount is clear, but the magnesium form is not identified. Complete use directions and inactive tablet ingredients are not included in the supplied data.

.

Customer satisfaction

72 High impact

The supplied average rating is very strong and backed by a substantial review pool. No review text is available to assess repeated complaints or purpose-specific experiences.

.

Value for money

84 Highest impact

A useful amount and low serving cost support good basic value. Unknown absorption quality keeps the product from being a clear category leader.

Magnesium · 250 mg

The 250 mg magnesium amount provides meaningful support for energy metabolism, muscle function, and nerve signaling. Magnesium has well-established foundational roles and common dietary relevance.

The label does not name the magnesium compound, so absorption and digestive tolerance cannot be judged. A focused single-mineral design is appealing, but the missing form prevents a confident quality assessment.

A meaningful magnesium amount can support normal vascular tone, rhythm-related physiology, and cellular energy. The single-ingredient design is fully focused and the elemental amount is clear.

The magnesium compound is not disclosed, so absorption quality and digestive tolerance cannot be judged. It supports one foundational cardiovascular pathway without broader lipid, nitric-oxide, or homocysteine coverage.

Magnesium at 250 mg meets the stated energy-support threshold and may help when inadequate intake contributes to fatigue. The single-tablet formula clearly states its elemental amount.

The magnesium compound is not disclosed, so absorption and digestive tolerance cannot be judged. The focused product supports one metabolic mineral pathway but no alertness or stress-resilience mechanism.

The clearly stated magnesium amount could support intestinal muscle function, but the missing magnesium form prevents a confident digestive assessment. Without knowing whether the source is citrate, oxide, or another compound, stool-softening potential and tolerance remain uncertain.

The single-ingredient design is clean and avoids unrelated additions. Its narrow coverage and poor form disclosure make it a basic magnesium option rather than a well-targeted digestive formula.

A useful amount of magnesium supports one mineral pathway involved in bone structure and vitamin D metabolism. The single-ingredient format is simple and avoids unrelated additives.

The label does not name the magnesium compound, so absorption quality cannot be judged. Calcium, vitamins D and K, and collagen-supporting nutrients are absent, leaving this far short of comprehensive bone support.

91 Performance

Krebs Magnesium Potassium Complex

Nature's Way
A more purposeful active profile is better aligned with the original’s main use because magnesium lysinate and malate provide favorable forms at a useful amount, with a modest potassium contribution. The focused formula offers excellent serving value.
85 Performance

Cal/Mag 500 mg/250 mg

NaturesPlus
A more purposeful active profile is better aligned with the original’s main use because chelated calcium and magnesium provide a focused, balanced mineral formula with strong form quality. A simple one-serving format and economical cost make it one of the better value profiles in this set.
85 Performance

Magnesium Bisglycinate 200 mg

Natural Factors
A more purposeful active profile is better aligned with the original’s main use because a focused magnesium bisglycinate powder uses a highly absorbable form at a moderate, practical amount. Strong aggregate satisfaction and reasonable serving economics support value without an aggressive dose.
83 Budget

Magnesium Citrate Pure Powder

Best Naturals
Lower serving cost makes it the more economical option, while a well-aligned amount of magnesium citrate delivers useful absorption in a focused powder. The simple formula and very low serving cost provide strong value, with digestive tolerance as the main practical uncertainty.
88 Budget

Magnesium Bisglycinate Powder

NOW
Lower serving cost makes it the more economical option, while magnesium bisglycinate supplies a well-absorbed form at a practical, moderate amount. The pure powder is adjustable, clearly labeled, and inexpensive, supporting strong routine value.
84 Budget

Potassium + Magnesium

Nutricost
Lower serving cost makes it the more economical option, while a meaningful magnesium citrate amount anchors a simple two-mineral electrolyte formula. Potassium is modest, but the focused design and very low serving cost support excellent everyday value.
83 Value

Magnesium Citrate 420 mg

Nutricost
Ingredient quality and serving value are better balanced here because a substantial amount of magnesium citrate offers useful absorption and a focused formula. Digestive tolerance is the main limitation, while the low serving cost makes the product highly competitive.
83 Value

Magnesium Citrate 200 mg

Best Naturals
Ingredient quality and serving value are better balanced here because a substantial amount of magnesium citrate combines useful absorption with a focused single-active design. Digestive sensitivity is the main trade-off, while the low serving cost supports strong practical value.
85 Value

Magnesium Bisglycinate Chelate

Healthy Origins
Ingredient quality and serving value are better balanced here because tRAACS magnesium bisglycinate provides premium absorption quality, a useful elemental amount, and exceptional serving value in a clean powder. The product is narrow rather than comprehensive, and its relatively weak satisfaction metric deserves consideration despite the strong formula.
