Overview
Bronson's Calcium formula combines 1200mg of calcium with 1000 IU of vitamin D3 per serving in a 120-tablet, non-GMO bottle, positioned as a high potency daily calcium and D3 combination.
Calcium and D3 are commonly paired because vitamin D supports calcium absorption, and Bronson lists this as a high potency formula relative to lower-dose calcium products. The listing does not specify flavor or additional diet claims beyond the non-GMO label, so buyers relying on those details should check the packaging directly.
- 1200mg calcium per serving
- 1000 IU vitamin D3 included
- 120 tablets, non-GMO
- High potency calcium formula
Who it's for
Fits people looking for a combined calcium and D3 tablet rather than separate bottles of each. Less useful for anyone who needs specific diet or flavor details confirmed beyond what is listed here, since that data is not included.
Strengths and trade-offs
Drawn from this product's published specifications.
- 1200mg calcium plus 1000 IU D3 combined
- 120 tablets per bottle
- Flavor and diet claims are not listed for this product
- Tablet form only, no gummy or capsule option
Performance notes
Vitamin D3 is included specifically to support calcium absorption, the standard rationale for pairing the two nutrients, and the 1200mg calcium amount is on the higher end for a single-product calcium supplement.
