A reliable and cost-effective calcium carbonate supplement from oyster shell, enhanced with Vitamin D3 for improved absorption and bone health.
Dose: 600mg, Quantity: 250
This Nature's Bounty product delivers calcium derived from oyster shell, which is chemically similar to calcium carbonate, alongside crucial Vitamin D3. The inclusion of D3 is vital as it significantly enhances calcium absorption in the small intestine and its proper integration into bone tissue. While oyster shell is a natural source, consumers occasionally express concerns about potential heavy metal contamination, though reputable brands like Nature's Bounty rigorously test for purity. Online reviews generally reflect satisfaction with the brand's reliability and the product's value, especially given the generous 300-serving bottle.
- Includes Vitamin D3, essential for effective calcium absorption and bone utilization.
- Very high serving count provides excellent long-term value and reduces frequency of repurchase.
- Comes from a widely recognized and trusted brand (Nature's Bounty).
- Provides a standard 500 mg elemental calcium dose per serving.
- Oyster shell calcium is predominantly calcium carbonate, which may not be optimally absorbed by individuals with low stomach acid.
- Lacks other synergistic nutrients like Vitamin K2, which are increasingly recommended for comprehensive bone and cardiovascular health.
- Some consumers may have concerns about sourcing or potential contaminants in oyster shell, despite brand testing.

Categories
Calcium 75.0
This product serves as a solid, cost-effective calcium supplement, boosted by the inclusion of Vitamin D3. Its score reflects its good value and brand reputation, though its calcium carbonate form places it below more bioavailable alternatives.
Goals
Bone Health 80.0
The combination of 500mg calcium and Vitamin D3 makes this an effective daily supplement for maintaining bone density and strength, particularly as part of a consistent regimen.
Fitness 70.0
Adequate calcium intake is vital for proper muscle contraction and nerve impulses, both essential for physical performance and recovery. This product contributes to meeting those needs, thus supporting overall fitness.
Heart Health 65.0
Calcium is critical for cardiac muscle function, and Vitamin D3 assists its metabolism. However, the absence of Vitamin K2 means it does not offer comprehensive support for ensuring calcium is properly directed to bones and away from arterial walls.
