✅ Why it works
  • High-dose calcium carbonate per tablet (1000 mg per tablet) providing quick antacid relief.
  • Gluten-free labeling present in product data and multiple retailer sources.
  • Large value-pack format (160-count per bottle, pack of 2) offering cost efficiency per dose.
  • Positive buyer feedback on speed of relief and taste; some buyers note added calcium+D value.
⚠ Keep in mind
  • Ingredient lists differ by source; some pages show conflicting calcium mg per tablet (400 mg elemental calcium in some listings vs 1000 mg calcium carbonate per tablet in others).
  • No explicit third-party gluten-free certification shown (GFCO/NSF) in the provided data; labeling relies on retailer claims rather than certification.
  • Some buyers wish for organic or fewer additives; at least one review notes desire for an organic version with fewer additives.

The product is labeled gluten-free across multiple sources, and the main active ingredient (calcium carbonate) does not contain gluten. However, explicit third-party gluten-free certifications are not evidenced in the supplied data, and inactive ingredients vary by listing.

What to expect

Expect fast-acting heartburn relief from chewable calcium carbonate, with a fruity flavor that many find pleasant. The product is a large-value pack, which can be convenient for regular use. Be aware that reported calcium content per tablet varies across sources, so per-serving calcium intake may differ depending on which listing you reference.

👍 Best for
  • Occasional heartburn relief (fast-acting chewable antacid).
  • Calcium supplementation, particularly noted by bariatric-relevant reviewer as beneficial when paired with vitamin D.
  • Customers who want a fruity flavored antacid chewable in a large value-pack format.
👎 Not ideal for
  • Shoppers seeking formal gluten-free certification (GFCO/NSF) with published facility details.
  • Customers requiring strictly organic or non-GMO products (no evidence of such claims in the provided data).
  • Consumers who require uniform mg calcium per tablet across all listings due to conflicting source data.

The full guide

What it is and how it works

Across sources, the format is described as a fruit-flavored chewable. Packaging details (value-size 160-count, two-bottle pack) point to a product designed for long-term use or higher monthly consumption. Note that the data do not show explicit third-party gluten-free certifications like GFCO or NSF; claims of gluten-free labeling come from retailer pages and product data.

Key takeaways

  • Check the exact mg calcium per tablet on your specific package, as reported values vary across sources.
  • Look for gluten-free labeling on the retailer listing and confirm on the product packaging; no third-party GF certification is shown in the data.
  • Consider the value-pack format if you want a long-lasting antacid with calcium supplementation.
  • If you need organic or non-GMO claims, this product may not meet that need based on the provided evidence.
How we assess this: Gluto summarizes manufacturer labeling, listing data, and community signals — it is not a medical guarantee. Always read the current label and confirm with the manufacturer before purchase, especially for celiac disease.

Evidence gaps for this product:
  • Explicit third-party gluten-free certifications (GFCO/NSF) are not evidenced in the provided data.
  • Facility-level cross-contact details and statements are not provided.
  • Conflicting magnesium/calcium mg per tablet data across sources (400 mg elemental calcium vs 1000 mg calcium carbonate per tablet) require reconciliation with official product labeling.
  • Amazon price is not shown in the supplied data; cross-retailer price variance is possible.
