About this product

A 200 mg elemental amount fits routine supplementation and offers more dosing flexibility than high-strength products. Missing chemical-form disclosure prevents a meaningful judgment of absorption or digestive behavior.

Three capsules per serving create moderate pill burden. The simple single-mineral format is easy to combine with other supplements, but no patented chelate or special delivery feature can be confirmed from the supplied data.

It may suit users already familiar with the complete label and who prefer a moderate dose. New buyers can obtain better transparency and value from products that name citrate, bisglycinate, or malate directly.

Who is it for
  • Adults seeking a moderate magnesium amount
  • Users who have verified the full current label
  • People comfortable with three capsules
Best for
  • Moderate-dose supplementation
  • Single-mineral routines
  • Users who want room to adjust intake

Pros

  • Provides 200 mg elemental magnesium
  • Moderate amount supports flexible dosing
  • Single-mineral active profile
  • Capsules may be easy to divide

Cons

  • Chemical form is not disclosed
  • Absorption cannot be assessed
  • High serving cost
  • Requires three capsules

Warnings

  • The 200 mg serving of supplemental magnesium may cause loose stools, cramping, or nausea; a smaller divided amount may be easier to tolerate.
  • Magnesium can reduce absorption of tetracycline or quinolone antibiotics; follow the prescriber or pharmacist’s spacing instructions.
  • Magnesium can interfere with levothyroxine absorption and should be separated according to medication guidance.
  • People with significantly reduced kidney function can accumulate magnesium and need clinician-guided use.

Product analysis

67 out of 100
A practical 200 mg serving is overshadowed by missing form disclosure, three-capsule dosing, and a high cost.

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

Nutrient quality76

The magnesium chemical form is absent, so the advertised absorption quality cannot be verified. The elemental amount is well aligned with everyday supplementation, while the moderate amount avoids obvious overdosing.

Ingredient transparency69

The elemental amount is stated, but the missing chemical form is a major naming gap. Serving totals are apparent, but full directions and inactive ingredients are not supplied.

Customer satisfaction72

The supplied average rating is exceptionally strong. The very large rating base makes the average unusually stable, while complaint and firsthand experience details are unavailable.

Value for money48

Quality and disclosure gaps weaken the asking position. The serving value is weak within the category.

Magnesium can provide foundational nervous-system support, and the listed amount is reasonable for daily supplementation. The supplied label data do not identify its chemical forms, making absorption quality impossible to verify.
