Bryan Johnson’s BluePrint Ceremonial Grade Matcha Tests Positive for Lead, Cadmium, & Arsenic Using Independent (Community-Funded), Third-Party Laboratory Testing
Published March 15, 2025 — Saturday
A Quick Note from Tamara Rubin:
In February 2025 (last month) we tested Bryan Johnson’s BluePrint Ceremonial Grade Matcha for Lead, Cadmium, Mercury, and Arsenic with independent, community-funded, third-party laboratory testing. Our full lab report can be found at the bottom of this article.
We also found (on his company’s website) results published online from the manufacturer’s internal testing of a batch of their product tested in December of 2024. Our results were comparable to their results, within a margin of error and taking into account the possibility of variation between batches. A screenshot from their website showing their internal test results can be found below.
- They report that their product tested positive for all four toxicants — Lead, Cadmium, Mercury, and Arsenic.
- Our report had a low threshold of detection of 5 ppb Mercury while their report showed that the Mercury levels for their matcha product came back at 3.98 ppb Mercury.
- 3.98 is less than 5, so those numbers are also consistent.
- Their level of about 18 ppb Arsenic is similar to our level of 12 ppb Arsenic.
- Their level of about 17 ppb Cadmium is similar to our level of 15 ppb Cadmium.
- Interestingly enough, their Lead level was significantly higher than what we found.
- We found 55 ppb Lead and they found almost 98 ppb Lead.
I personally found these test results amusing as I saw that Bryan was mentioned on Stephen Colbert’s show recently in response to the fact that he publicly shared how his erections are almost (but not quite) as strong and frequent as his son’s erections (!!!). (Here’s a link with more on that!) Given the known causal link between persistent/ chronic, low-level, trace Lead-exposure and reproductive disorders (including erectile dysfunction), I can only wonder if Bryan’s erectile performance might be closer to his son’s if he stopped consuming his BluePrint matcha (especially with the known/ quantified relatively significant level of Lead found in this BluePrint brand Matcha product — as shown both through BluePrint’s published internal lab test results (see below) and Lead Safe Mama, LLC’s independent, community-funded, third-party testing of this same product!).
- As always (to repeat what has become a bit of a mantra here at Lead Safe Mama, LLC), all federal agencies agree there is no safe level of Lead exposure for human beings (especially pregnant women and children).
- Serving size does not matter when we are talking about toxicants as potent and dangerous as Lead, Cadmium, and Mercury.
- Lead and other heavy metals bioaccumulate in the body over time — especially with persistent, chronic/ daily exposure.
- Lead that is ingested (in food products) is particularly concerning.
Please scroll to the bottom of the page to see the full original lab report for this product.
- The levels of toxicants found in this matcha product are 100% LEGAL.
- Just because something is LEGAL does not mean it is ok, nor that it is actually safe for consumption by children or pregnant women.
- Most regulatory standards were designed primarily to protect corporations from liability, not to be protective of human health (watch our documentary film linked here for more information).
If you are interested in knowing more about detox protocols to support your family’s health (in response to learning this new information about the toxicant profile of this product or any other product you have been using), please read this article first — here’s the link. Most detox protocols and potions sold are hoaxes (ineffective or even dangerous) that are a waste of money and can often result in additional Lead exposure for your family.
The full lab report for this product is at the bottom of this article.

Below is an EXPANDING list of products (foods, supplements, and cosmetics — including one toothpaste product) that have tested “non-detect” for Lead, Mercury, Cadmium, and Arsenic with independent, third-party, crowd-funded laboratory testing coordinated by Lead Safe Mama, LLC (an Oregon-based small business with a unique community-collaborative business model and a focus on consumer goods safety and childhood Lead poisoning prevention). These products provide clear evidence that foods, supplements and cosmetics do not have to test positive for concerning levels of toxicants — toxicant contamination is not something we need to accept, we can (and should) demand more from product manufacturers.
