Overview
This is a calcium citrate tablet paired with vitamin D3, dosed at 1200 mg per serving across 180 unflavored tablets, a 60-day supply. It targets shoppers building a daily bone-support routine who want a slow-release format and a gluten free batch.
Calcium citrate is generally easier to absorb than calcium carbonate, especially without food, and pairing it with D3 follows the standard practice of aiding calcium uptake. The listing markets the tablets as slow release and lab tested, but no independent absorption data accompanies the claim.
- 1200 mg calcium citrate plus vitamin D3
- 180 tablets, a 60-day supply
- Gluten free formulation
- Marketed as slow release and lab tested
Who it's for
Adults building a daily calcium and D3 habit who want a two-month supply in one bottle. Not for anyone who needs a specific calcium form confirmed by a clinician first.
Strengths and trade-offs
Drawn from this product's published specifications.
- Gluten free formulation
- 60-day supply in one bottle
- Slow-release calcium citrate for steadier absorption
- Generic brand name, no track record
- No independent lab data included in listing
Performance notes
Citrate-form calcium absorbs without needing to be taken with food, unlike carbonate forms, and the D3 pairing supports the body's calcium uptake. The slow-release claim comes from the listing itself rather than independent testing data.
