A liquid calcium and magnesium supplement with lower bioavailability forms and very low Vitamin D, offering an unconventional magnesium-heavy ratio.

insightsAnalysis

This liquid supplement from Kirkman delivers calcium as carbonate (312mg) and a blend of magnesium citrate (195mg) and magnesium oxide (195mg), totaling 390mg of magnesium. The calcium carbonate is less bioavailable, and the magnesium blend includes a less absorbable form. Furthermore, the Vitamin D content (1mcg) is very low, providing minimal support for calcium absorption.

The product has an unusual ratio where magnesium is higher than calcium, which might be suitable for specific individual needs but is not a typical balanced Cal-Mag offering. While the liquid form is convenient for some, the overall mix of less bioavailable forms and low Vitamin D makes it a less optimal choice for comprehensive mineral support.

thumb_upPros
  • Liquid form for easier consumption, especially for those who struggle with pills.
  • Contains magnesium citrate, a more bioavailable form.
  • Unconventional ratio may suit individuals with specific magnesium needs.
thumb_downCons
  • Calcium is in less bioavailable carbonate form.
  • Includes magnesium oxide, a less absorbable form.
  • Very low Vitamin D content provides minimal support for calcium absorption.
  • Unusual magnesium-heavy ratio might not suit general calcium-magnesium needs.
  • Contains calories and carbohydrates, which might be a consideration for some diets.
warningWarnings
  • Due to calcium carbonate, it's best taken with food to aid absorption.
  • Magnesium oxide can have a laxative effect in some individuals.
  • If you require more robust calcium support, consider a separate Vitamin D supplement or a product with higher D content.

Impact
Moderate effect
Magnesium citrate can aid regularity, but the inclusion of magnesium oxide might cause digestive upset in sensitive individuals, though the liquid form can be gentle.

flagGeneral Health
Impact
Moderate effect
Offers basic quantities of calcium and magnesium for general mineral needs, but the forms are not optimal for broad systemic benefits.
View goal →
flagBone Health
Impact
Moderate effect
The calcium carbonate form and very low Vitamin D content mean it offers limited effectiveness for robust bone health support compared to options with more bioavailable forms and adequate D.
View goal →
flagHeart Health
Impact
Moderate effect
While containing these minerals, the mixed and less bioavailable forms mean it provides only basic support for cardiovascular functions, rather than targeted benefits.

flagCardiovascular Support
Impact
Moderate effect
With a mix of less bioavailable calcium and magnesium forms, its contribution to robust cardiovascular support is modest at best, primarily through foundational mineral intake.

flagFitness
Impact
Moderate effect
The lower bioavailability of some electrolytes limits its effectiveness for supporting rigorous fitness and optimal muscle function needs.
View goal →
flagMood Support
Impact
Moderate effect
Magnesium citrate contributes to nervous system balance, but the inclusion of less bioavailable magnesium oxide limits its overall effectiveness for mood support.

flagEnergy
Impact
Moderate effect
Magnesium is a cofactor in energy production, but the mixed forms mean its contribution to cellular energy may be less consistent than with fully bioavailable options.

Magnesium 60
While magnesium citrate is a good form, the equal inclusion of less bioavailable magnesium oxide significantly reduces the overall quality and absorption effectiveness of the magnesium component.

Calcium 55
Calcium is provided in carbonate form, which is less bioavailable and requires adequate stomach acid for absorption, limiting its overall effectiveness.
