Score 85.0

A highly bioavailable Calcium Amino Acid Chelate supplement, effectively balanced with Magnesium, offering excellent value and gentleness, though it lacks Vitamin D3.

Analysis

Source Naturals Calcium & Magnesium provides calcium as an Amino Acid Chelate, a form praised by nutritionists and online reviews for its high bioavailability and gentleness on the digestive system, reducing the likelihood of gastrointestinal upset common with other forms. Crucially, it includes Magnesium, which is essential for activating Vitamin D, transporting calcium, and preventing calcium from accumulating in soft tissues like arteries. This balanced combination promotes optimal bone mineralization and supports overall physiological functions. With a competitive price per serving and a very high review count, it represents a well-received and effective option, although the absence of added Vitamin D3 means users would need to ensure adequate D3 intake from other sources.

Pros
  • Features Calcium Amino Acid Chelate, a highly bioavailable and gentle form.
  • Includes Magnesium, essential for calcium utilization and overall mineral balance.
  • Excellent price per serving, offering great value for a quality chelated formula.
  • High review count indicates widespread consumer satisfaction.
Cons
  • Does not include Vitamin D3, which is critical for optimal calcium absorption.
  • Low elemental calcium dosage (200mg) requires multiple servings for higher daily intake.
