Analysis

Cal-Mag Citrate delivers 1000mg of calcium and 500mg of magnesium in citrate and oxide forms to support bone density and muscle function. The citrate forms are particularly beneficial for individuals with low stomach acid, as they are easier to absorb than standard carbonates. This capsule-based formula aims to provide structural and metabolic support in a balanced ratio.

The inclusion of Vitamin D2 supports the biological processes required for mineral utilization and immune function. Providing high elemental yields of both minerals makes this a robust option for individuals needing consistent mineral replenishment. It serves as a foundational supplement for maintaining skeletal health and managing everyday mineral requirements.

Pros

Uses bioavailable citrate mineral forms
Convenient 2:1 mineral ratio
Supports both skeletal and muscular health
Affordable daily mineral option

Cons

Uses Vitamin D2 instead of D3
High magnesium dose may cause sensitivity in some

Warnings

May cause loose stools if you have high magnesium sensitivity
Take in divided doses for optimal absorption

Nutrient quality

Highest impact

Organic citrate salts ensure moderate bioavailability for skeletal structural support. Meaningful dosages align with standard clinical recommendations for addressing daily mineral requirements.

Ingredient transparency

Highest impact

Labeling clearly identifies the source of minerals and the specific forms used in the composition. High transparency regarding elemental amounts supports precise nutritional tracking for bone health goals.

Customer satisfaction

Highest impact

Average rating of 4.78 across over a thousand reviews demonstrates high reliability and user satisfaction. Feedback suggests that the formula meets consumer expectations for effectiveness and tolerance.

Value for money

High impact

Cost per serving is relatively high compared to basic mineral capsules. Pricing reflects the inclusion of citrate forms and the reputable branding for mineral supplements.

Magnesium citrate and oxide work alongside calcium to support the essential biological processes involved in ATP generation. Magnesium is a mandatory cofactor for enzymes that produce cellular energy, making it a foundation for physical vitality.

The 500mg dose of magnesium is high and appears well aligned with correcting deficiencies that cause lethargy. However, the inclusion of magnesium oxide may contribute to lower overall absorption compared to purely chelated forms.

Combines Magnesium Citrate and Oxide to deliver 500 mg of magnesium for supporting vascular relaxation and heart rhythm. Magnesium is a cornerstone mineral for cardiovascular stability and is well-supported by clinical evidence for these benefits.

While the total dose is high, the inclusion of Magnesium Oxide lowers the overall bioavailability of the mineral complex. It serves as a foundational supplement for heart-relevant minerals but lacks premium chelates for maximum systemic benefit.

Calcium citrate and magnesium citrate provide a significant supply of structural minerals for skeletal density. Cholecalciferol or ergocalciferol assists in mineral transport, though the latter is less effective for bone density maintenance.

The 2:1 mineral ratio is logically constructed to balance structural requirements for mineralization. While effective for structural supply, the formula misses secondary matrix cofactors like manganese or boron.
