Analysis

Calcium and magnesium are provided in a two-to-one pattern that fits general bone and muscle nutrition. Asporotate forms add some formulation interest, while glutamic acid and the herb base play secondary roles.

Magnesium oxide is less appealing than more soluble forms, and the supplied label repeats magnesium quantities across forms in a way that makes the elemental split unclear. The four herbs are grouped under one base amount, so their individual contributions cannot be assessed.

Four capsules per serving create a noticeable pill burden, though the serving value is reasonable. It fits users seeking combined calcium and magnesium who tolerate larger mineral servings.

Who is it for
  • Adults seeking combined calcium and magnesium
  • People comfortable with a four-capsule serving
  • Users wanting a mineral formula with a small herb base
Best for
  • Bone mineral support
  • Calcium-magnesium convenience
  • General muscle nutrition

Pros

  • Provides meaningful calcium
  • Includes a substantial magnesium amount
  • Uses a two-to-one mineral pattern
  • Adds several plant ingredients

Cons

  • Includes magnesium oxide
  • Mineral form splits are unclear
  • Requires four capsules
  • Herb amounts are not individually disclosed

Warnings

  • A large magnesium serving may cause loose stools or abdominal cramping
  • Count the supplemental calcium with dietary intake
  • Dandelion may affect fluid balance in users taking diuretic medicines

Nutrient quality

Magnesium · 250 mgCalcium · 500 mg

Calcium and magnesium provide complementary structural minerals in clearly disclosed amounts. Chelated asporotate forms improve the formula, although part of the magnesium is supplied as lower-absorption oxide.

The mineral pairing offers broader support than either mineral alone but lacks vitamin D, vitamin K, and collagen-building nutrients. The added herb blend does not meaningfully strengthen the skeletal purpose.

Magnesium · 250 mg

Calcium and magnesium offer relevant support for bone, muscle, and metabolic function. The elemental amounts are useful for routine nutritional coverage.

Magnesium asporotate is paired with lower-absorption oxide, so uptake is likely uneven. Several small herbal additions lack a clear role in the mineral formula.

Magnesium · 250 mg

Magnesium supports ATP-dependent reactions at a meaningful supplemental amount. Calcium and herbs make the formula more mineral and wellness oriented than specifically energizing.

The mixed magnesium source includes oxide, which lowers expected absorption. The herbal base is not tied to well-established energy effects and adds unnecessary bulk.

Magnesium · 250 mg

A meaningful magnesium amount supports heart rhythm and vascular tone, while calcium provides broader mineral context. The aspartate component offers some absorption potential.

Magnesium oxide lowers overall form quality, and the herb base does not provide clearly standardized cardiovascular actives. Four capsules deliver a formula that remains focused mostly on bone minerals rather than multiple heart pathways.

Magnesium provides foundational support for nervous-system regulation and relaxation. Its role is supported by established physiology, with the clearest benefit expected when intake or status is low.

The 250 mg magnesium amount reaches a useful supplemental range. Asporotate may support absorption, but included magnesium oxide lowers the blend's quality.

Report overview
Calcium (Calcium Asporotate) · 500 mg OverallScore90
A+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyD+ Value

The chelated calcium asporotate form and 500 mg serving are well aligned with absorption and dose efficiency. Elemental calcium is clearly disclosed, and the broader mineral-and-herb formula adds useful context to its moderately high cost. The four-capsule serving may be less convenient for daily use, but no specific safety concern is evident from the supplied amounts.

Glutamic Acid · 50 mg OverallScore76
B- Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyB- Value

Glutamic acid hydrochloride is a suitable form for a mineral complex, but the label does not confirm the biologically active L-isomer. The individually listed amount provides a moderate supplemental dose with clear disclosure. Its per-serving cost remains reasonably close to the collection benchmark.

View ingredientView products
Magnesium (Magnesium Asporotate, Magnesium Oxide) · 250 mg OverallScore56
F Active Ingredient Quality & BioavailabilityA- Dose, Safety & Label TransparencyD- Value

The aspartate and oxide blend offers mixed absorption because the better form is diluted by low-bioavailability oxide. 250 mg of elemental magnesium is clearly disclosed and falls in the standard supplemental range; no vitamin B6, boron, or vitamin D cofactor is supplied to strengthen the magnesium rationale. Value is limited because the serving costs more than average without a premium chelation standard.
