Analysis

The chelated tablet formula supplies 500 mg calcium and 200 mg magnesium. The combination supports normal bone mineralization, muscle function, and nerve signaling when dietary intake is insufficient.

bisglycinate gives both minerals strong absorption potential and the amounts are practical. magnesium oxide weakens the blend and the serving value is poor.

It fits adults who need both minerals and prefer a tablet format. Dosing should be matched to dietary intake, tolerance, kidney function, and medications rather than assuming more mineral is always better.

Who is it for
  • Adults with a demonstrated calcium and magnesium gap
  • Users who prefer tablet supplements
  • People seeking combined bone-mineral support
Best for
  • Calcium and magnesium supplementation
  • Bone-mineral support
  • Muscle and nerve nutrient support

Pros

  • Uses calcium bisglycinate and magnesium bisglycinate alongside magnesium oxide
  • bisglycinate gives both minerals strong absorption potential and the amounts are practical
  • Clearly stated mineral amounts

Cons

  • magnesium oxide weakens the blend and the serving value is poor
  • Does not replace dietary mineral assessment
  • Complete inactive ingredients or directions are not supplied

Warnings

  • Calcium and magnesium can reduce absorption of levothyroxine, tetracycline or quinolone antibiotics, and bisphosphonates when taken together
  • Supplemental magnesium may cause diarrhea or abdominal cramping
  • The oxide portion may loosen stools, especially if the whole serving is taken at once

A Goal FitB+ Strength of SupportB CoverageA- Formula Quality
Magnesium · 200 mg

Calcium and magnesium provide foundational structural, muscular, nervous-system, and metabolic support. The amounts are substantial, and bisglycinate improves the quality of both minerals.

A meaningful share of the magnesium also comes from less absorbable oxide, while the calcium-heavy ratio may create absorption competition. Magnesium oxide can increase digestive upset in sensitive users, and the three-caplet serving is less streamlined than a focused magnesium product.

Chelated calcium and magnesium provide a focused structural mineral combination. Bisglycinate forms support absorption, although part of the magnesium also comes from oxide.

The amounts are useful for bone support and fit a practical mineral ratio. Vitamin D, vitamin K, and collagen are absent, so mineral regulation and matrix coverage remain incomplete.

Magnesium provides direct nervous-system and muscle support at a meaningful but moderate amount. Its role in correcting inadequate magnesium intake is well established, though direct stress-relief effects vary by baseline status.

Magnesium bisglycinate improves form quality, while magnesium oxide lowers expected absorption. Calcium adds mineral nutrition but little direct stress-modulating breadth.

Magnesium supports normal vascular tone, cardiac rhythm, and cellular energy at a meaningful but moderate amount. Its cardiovascular role is well established, especially when intake is inadequate.

Bisglycinate improves form quality, while magnesium oxide lowers expected absorption and calcium shifts the focus toward bone health. The mineral pairing is coherent but does not address lipids, nitric oxide, or cardiac energy.

Magnesium reaches the 200 mg energy-support threshold and serves as a direct ATP cofactor. Bisglycinate improves part of the mineral’s absorption profile.

Magnesium oxide lowers overall quality, while the larger calcium amount may compete for absorption. The formula addresses one mineral pathway and is designed mainly for structural support.

Magnesium provides relevant support for vascular tone and normal rhythm, but the mineral pairing is not optimized for that purpose. Magnesium oxide lowers absorption quality, while calcium substantially exceeds magnesium.

The elemental magnesium amount is useful, though competition from calcium may reduce effective delivery. The formula is coherent for combined mineral supplementation but less compelling as focused cardiovascular support.

Magnesium · 200 mg

Two hundred milligrams of magnesium provides a meaningful amount of a nutrient linked to free-testosterone regulation, especially when magnesium status is low. The formula does not address stress regulation, zinc status, boron, or other major endocrine pathways.

The bisglycinate component is useful, but oxide and competing calcium reduce confidence in absorption. Without vitamin D, zinc, or an adaptogen, the product remains a narrow mineral option rather than a complete testosterone formula.

Calcium (Calcium Bisglycinate Chelate) · 500 mg OverallScore84
A+ Active Ingredient Quality & BioavailabilityA+ Dose, Safety & Label TransparencyF Value

Calcium bisglycinate offers strong absorption potential, and the listed serving provides an efficient calcium amount. The mineral amount and form are clearly identified, while no problematic additives appear in the supplied ingredient data. Value is limited because the cost per serving sits above the collection's typical range.

D- Active Ingredient Quality & BioavailabilityB+ Dose, Safety & Label TransparencyF Value

Bisglycinate improves the blend, but magnesium oxide lowers absorption quality despite a well-aligned elemental amount. Calcium exceeds magnesium by more than two to one, creating direct competition for absorption. The costly serving offers weak value, and the oxide component may increase digestive upset.
