Analysis

Solaray Cal-Mag Citrate with Vitamin D-3 & K-2 offers 1000mg of Calcium Citrate, which is a highly recommended and bioavailable form of calcium, along with 50mcg of Vitamin K2 (form not specified, but beneficial). The product name also explicitly states 'with Vitamin D-3,' which is crucial for calcium absorption and utilization. A significant portion of the magnesium is 500mg of Magnesium Oxide, a form with lower absorption rates compared to other types like citrate or chelate, despite the high elemental dose. Nutritionists often praise the inclusion of D3 and K2 alongside calcium for synergistic bone and cardiovascular benefits. The 2:1 calcium to magnesium ratio is also generally ideal. Overall, it's a strong contender for bone health due to its key ingredients and dosages, with the magnesium form being the main area for improvement.

Pros
  • Excellent dosage of Calcium Citrate (1000mg), a highly bioavailable form.
  • Includes Vitamin K2 (50mcg), crucial for calcium utilization and arterial health.
  • Implied presence of Vitamin D3, essential for calcium absorption.
  • Good 2:1 Calcium to Magnesium ratio.
  • Reasonable price per serving for a comprehensive formula.
Cons
  • Magnesium is in the less bioavailable Magnesium Oxide form, limiting its absorption despite the high dose.
  • Specific form of Vitamin K2 (MK-4 vs MK-7) is not specified.
