Toothpaste

Email to Purity Laboratories Inc Regarding Lead Safe Mama’s Revitin Toothpaste Claims

October 1, 2025

Introduction

In light of recent concerns raised by Lead Safe Mama about potential heavy metal contamination in Revitin Prebiotic Toothpaste (fluoride-free, citrus flavor), I have reached out to Purity Laboratories Inc for clarification.

Below is the full text of my email sent on 9/30/25. This post will be updated with any responses or follow-up correspondence. For the complete investigation and ongoing updates, see the main article: [Link to Main Blog Post].

Request for Clarification on Testing of Revitin Toothpaste

Dear Laboratory Director,

My name is Dr. Trino Nuño, and I am a dentist practicing in Nebraska with a focus on biological and integrative dentistry. I recently became aware of a report by Lead Safe Mama LLC alleging that one sample of Revitin Prebiotic Toothpaste (fluoride-free, citrus flavor) tested positive for heavy metal contaminants, including lead.

As part of my commitment to patient safety and accurate public health communication, I am seeking to better understand the testing performed by your laboratory. If possible, I would appreciate clarification on the following points:

1. What specific analytical method(s) were used (e.g., ICP-MS, XRF)?
2. What was the limit of detection (LOD) and limit of quantification (LOQ) for the analysis?
3. How many toothpaste samples were tested, and were they from a single batch or multiple lots?
4. What quality control measures (calibration standards, blanks, duplicates) were implemented to ensure accuracy and reproducibility?
5. Has your lab conducted or do you plan to conduct any replicate or confirmatory testing on additional samples?

My intent is not to challenge your work, but to gather accurate, technical details that will help me advise my patients and present this information responsibly. Understanding your methodology and scope will also allow me to compare your results with any data Revitin may provide regarding their own internal or third-party testing.

Thank you for your time and for the important role you play in advancing transparency in product safety. I would be grateful for any details you are able to share.

With respect,
