Score 88.0

A high-dose calcium carbonate supplement providing abundant calcium optimally paired with a strong dose of Vitamin D3 for absorption. It's excellent for bone health but lacks magnesium and Vitamin K2 for comprehensive bone and heart support.

Analysis

This Sundown Naturals product provides a high dose of 1200mg elemental calcium (as calcium carbonate) per serving, which often meets or significantly contributes to daily calcium requirements. Crucially, it includes 25mcg (1000 IU) of Vitamin D3, an optimal amount known to significantly enhance calcium absorption and utilization, making the calcium highly effective. The product's high review count reflects strong user satisfaction and perceived efficacy. While calcium carbonate can be less absorbable for those with low stomach acid and may cause digestive upset in some, the high dose and inclusion of ample Vitamin D3 generally compensate. The primary limitation is the absence of synergistic minerals like magnesium (vital for bone mineralization and calcium balance) and Vitamin K2 (essential for directing calcium to bones and away from arteries), which would make it an even more complete bone and heart health supplement.

Pros
  • Delivers a high dose of 1200mg elemental calcium per serving, effectively meeting daily needs.
  • Includes a robust and effective dose of Vitamin D3 (1000 IU), crucial for calcium absorption and utilization.
  • Popular with a large number of positive reviews, indicating high user satisfaction and widespread trust.
  • Offers good value for money given the high dosages of both calcium and Vitamin D3.
Cons
  • Uses calcium carbonate, which may require sufficient stomach acid for optimal absorption and can cause digestive issues like constipation in some individuals.
  • Does not include other crucial co-factors such as magnesium or Vitamin K2, which are important for comprehensive bone health and arterial calcification prevention.
Warnings
  • Individuals with a history of kidney stones or hypercalcemia should consult a healthcare provider before taking high doses of calcium and Vitamin D.
  • Best taken with food to aid absorption of calcium carbonate.

Report overview

Categories

This product is an outstanding calcium supplement due to its high elemental calcium and robust Vitamin D3 content, making it highly effective for bone health. Its strong market presence and value further solidify its position as a top choice in the calcium category, despite lacking additional co-factors like magnesium and K2.

Goals

The high calcium dose combined with excellent Vitamin D3 support makes this product highly effective for bone density and strength. Its main limitation for a perfect score is the absence of magnesium and Vitamin K2 for comprehensive bone matrix support.
Essential for muscle contraction, nerve impulses, and bone strength, the high doses of calcium and Vitamin D3 offer excellent support for fitness and athletic performance. It helps maintain skeletal integrity crucial for high-impact activities.
Adequate calcium and Vitamin D are important for cardiovascular health. This product provides a good foundation, but the absence of Vitamin K2, which helps direct calcium to bones and away from arterial walls, is a factor preventing a higher score for comprehensive heart health support.
