Overview
Kirkland Signature's calcium and vitamin D3 gummies come in strawberry flavor, 120 to a bottle, formulated specifically for adults and labeled gluten free. The combination of calcium with D3 targets bone health support in a chewable format.
Costco's private label line puts calcium and vitamin D3 into one strawberry gummy rather than selling them as separate tablets, aimed at adults who'd rather chew a gummy than swallow a pill. D3 is the usual pairing partner for calcium supplements because it plays a role in how the body absorbs it.
- 120 gummies per bottle
- Calcium combined with vitamin D3
- Strawberry flavored, gluten free
- Formulated specifically for adults
Who it's for
Adults who want a chewable, strawberry-flavored way to get calcium and vitamin D3 rather than swallowing tablets.
Strengths and trade-offs
Drawn from this product's published specifications.
- Chewable gummy format, no pill swallowing
- Calcium paired with D3 in a single gummy
- Large 120-count bottle
- Only available in strawberry flavor
- Formulated for adults, not a children's dose
Performance notes
Vitamin D3 is included alongside the calcium here because it's the nutrient most commonly paired with calcium supplements for absorption support, which is why the two rarely get sold separately in this format. The gummy delivery trades tablet-style dosing precision for ease of chewing, which is the tradeoff buyers are making by choosing this over a calcium tablet.
