About Caltrate

Caltrate is a brand focused on calcium supplements and bone health products. The founding date of Caltrate is unknown. Caltrate is owned by Haleon, formerly GSK Consumer. Caltrate products are widely available in drugstores and supermarkets.

Product Specialization

Caltrate specializes in calcium supplements and products designed to support bone health. Their product line includes calcium carbonate and calcium citrate formulations, often combined with vitamin D to enhance calcium absorption. Caltrate is known for offering a range of calcium supplements tailored to different age groups and dietary needs.

Testing & Certifications Explained

Caltrate is GMP Certified, meaning the manufacturing facility adheres to Good Manufacturing Practices as defined by regulatory bodies. GMP certification ensures that products are consistently produced and controlled according to quality standards. However, GMP certification does not guarantee that the ingredients are pure, potent, or accurately labeled. The absence of third-party testing means there is no independent verification of these factors.

How Caltrate Compares

Compared to competitors like Nature Made (trust score 72/100, third-party tested) and NOW Foods (trust score 88/100, third-party tested and publishes lab results), Caltrate's trust score is considerably lower. Many leading calcium supplement brands pursue third-party testing to demonstrate product quality and safety. Garden of Life (trust score 92/100) is another competitor that is both third-party tested and publishes lab results, offering greater transparency than Caltrate.

Buying Guidance

Given Caltrate's low trust score and lack of third-party testing, consumers should carefully consider alternatives. If you choose to use Caltrate, purchase from reputable retailers and carefully review the product label. Consult with a healthcare professional before taking any new supplement, especially if you have existing health conditions or are taking other medications. Consider reading Caltrate reviews from multiple sources.
