An affordable coral calcium supplement providing a modest dose, but lacking the crucial Vitamin D3 and K2 for optimal bone and cardiovascular health.

Quantity: 100
Analysis

This product contains coral calcium, which provides elemental calcium (350mg per serving) primarily as calcium carbonate, along with natural trace minerals. The 350mg dose is a good amount for single-serving absorption. While coral calcium is bioavailable, its absorption characteristics are similar to other forms of calcium carbonate, generally requiring stomach acid and thus best taken with food. A significant drawback is the complete absence of Vitamin D3, which is vital for calcium absorption, and Vitamin K2, which directs calcium to bones and prevents arterial calcification.

Pros
  • Very affordable price per serving ($0.09).
  • Provides elemental calcium in a moderate, well-absorbed dose.
Cons
  • Does not include Vitamin D3, essential for calcium absorption.
  • Lacks Vitamin K2, crucial for directing calcium to bones and away from arteries.
  • Coral calcium is primarily calcium carbonate, which may require food for optimal absorption and can cause constipation in some.
Warnings
  • Without Vitamin D3, the calcium provided may not be adequately absorbed.
  • The absence of Vitamin K2 raises concerns about calcium deposition in soft tissues, particularly at higher calcium intake levels over time.

Categories
Calcium 45.0
Offers a cost-effective source of coral calcium, but its efficacy is diminished by the lack of essential synergistic nutrients like Vitamin D3 and K2 that are crucial for enhancing calcium's benefits and ensuring proper utilization.
Goals
Bone Health 45.0
Provides a basic building block for bones through its calcium content, but the absence of essential Vitamin D3 and K2 means it doesn't fully support optimal calcium absorption and its proper integration into the bone matrix.
Joint Health 40.0
While calcium contributes to skeletal health supporting joints, this product offers only a basic mineral contribution without synergistic vitamins for comprehensive support and long-term joint integrity.
Fitness 40.0
Supplies elemental calcium vital for muscle contraction and nerve impulses, providing fundamental support for physical activity, but is limited by the absence of other cofactors that would enhance overall physiological benefits.
