Myth: Ceylon Cinnamon is Beneficial for Your Health. Fact: 100% of Ceylon Cinnamons Test Positive for Concerning Levels of Heavy Metals.
Published: April 30, 2026
A Quick Note From Tamara Rubin
Below you will find a comparative chart showing the lab test results for all of the Ceylon Cinnamon products we have sent in for independent, third-party laboratory testing to date (since we started the Lead Safe Mama, LLC Community Collaborative Laboratory Testing Initiative in March of 2024). There are currently lab test results for five products included in this chart as of the date of publishing. We have two lab reports for Ceylon Cinnamon products pending publishing (including one of the products shown in the chart).
- As noted in the chart graphic below:
- 80% of the Ceylon Cinnamon Products Tested Positive For Lead
- 100% of the Ceylon Cinnamon Products Tested Positive For Cadmium
- 60% of the Ceylon Cinnamon Products Tested Positive For Mercury
- 80% of the Ceylon Cinnamon Products Tested Positive For Arsenic
As always – to see the full original lab report for each product shown in the chart, click the link for the article for that specific product (the numbers in the list of linked articles below correspond with the numbers for each of the products shown in the chart below) and scroll down to the very bottom of the article. The lab reports are always BELOW the sharable social media graphic and BELOW the list of Lab Tested Safer Choices that is embedded in each article.
As with nearly all of the lab test results we share, we will take a moment reiterate a key point: All relevant federal agencies have published statements that are in agreement with the consensus in the scientific and medical communities that there is no safe level of Lead exposure for human beings — especially in products that will be ingested.
The logic for the above concern for Lead exposure also applies to Mercury exposure and Cadmium exposure. Cadmium is a known carcinogen, Lead is a neurotoxin ad a carcinogen, Mercury is a neurotoxin. Arsenic is also a carcinogen. Daily consumption of products that are heavily contaminated with these toxic heavy metals is especially concerning.
The asserted “health beneficial” properties alleged to be present with daily consumption of Ceylon Cinnamon powder do not take into account the concern for detrimental effects of daily consumption of a significantly heavy metals contaminated product. It is possible that – a century ago, or even 50 years ago – Ceylon Cinnamon was (at some point in human history) not heavily contaminated with neurotoxic heavy metals. This is not the case in the current century.
Alleged Health “Benefits” of Ceylon Cinnamon:
Countering The Above Misinformation About the Health Beneficial Properties of Daily Consumption of Ceylon Cinnamon — Below Are Potential Negative Health Impacts of Daily Exposure to the Heavy Metals Found in Ceylon Cinnamon:
#1) Heavy metals exposure (especially, but not limited to Lead), has been shown to be causal in DECREASED kidney function — with links to being causal (directly or indirectly) in contributing to diabetes. One Related Source – Link
#2) Lead has been repeatedly demonstrated to negatively impact cardiovascular health, especially with persistent, chronic, low-level exposure that one may find in daily dietary sources — like Ceylon Cinnamon. One Related Study – Link
#3) Heavy metals exposure has been demonstrated to cause inflammation throughout the body. One Related Study – Link.
#4) Lead and Mercury have been definitively shown to cause neurocognitive damage – specifically contributing to an increased risk of early onset Alzheimer’s. One Related Study – Link.
#5) Heavy metals exposure has been repeatedly demonstrated to – again – be causal in significantly interrupting the function of the GI system – increasing inflammation and GI dysfunction. One Related study – Link.
Our goal is to share independent, third-party (non-industry influenced) science to help you make science-backed informed decisions for your families. It is our recommendation that Ceylon Cinnamon not be consumed (at all), given the pervasive contamination of this class of product. The alleged “health protective” qualities of this contaminated food appear (when looking at the science) to be entirely negated by the potential for damage to be caused.
In sharing all of the above it is important to note that we are not dealing with a “dose makes the poison” situation when it comes to heavy metals exposure – especially heavy metals exposure introduced via the diet. There is no safe level of exposure to these heavy metals, and – in most cases – the impact is cumulative over a lifetime, with the negative health impacts showing up over time in response to chronic exposure. So while you may be “fine” now, the long-term impact may not yet be realized.
If you are concerned about detoxing from years of exposure, the scientifically proven most effective natural detox method is garlic consumption (fresh, raw or cooked is better than processed, dried, or powdered).

RE D APE has Ceylon cinnamon and they test every batch for heavy metals and are transparent. Glad I found them.
Theirs is also heavily contaminated. They just hide the levels by reporting them in ppm (not ppb). Food toxicity is measured in ppb, not ppm.
