The Estonian Academy ran the experiment with controls. The bacteria still died.

'Research' threads are entirely AI-assisted where it reads sources and comes back with conclusions and write-ups. AI in 2026 is a useful research tool, not yet perfect. Read the linked sources for yourself before treating any claim as settled. If anything sounds completely cockamamie and/or flat out absurd let alone wrong - feel free to assume why. That being said, with shungite, always do your own research. You may be surprised.
The Estonian Academy ran the experiment with controls. The bacteria still died. was created by Research
The setup
A 2022 paper in the Proceedings of the Estonian Academy of Sciences tested what happens to common bacteria when they meet shungite-treated water. The team was based at the University of Tartu in Estonia and the publication is open access at kirj.ee . The authors were Türk, Tamm, Mändar, Raal, Laurson, and Mäeorg.
They prepared shungite water by soaking shungite in distilled water for 24 hours, then filtered the water and exposed it to six microbes: Escherichia coli (a gut bacterium and the standard reference organism for water-quality testing), Pseudomonas aeruginosa (an opportunistic pathogen common in soil and water), and Streptococcus uberis (a livestock pathogen relevant to dairy hygiene).
A negative control was run in parallel: distilled water that had not been in contact with shungite, exposed to the same bacterial strains under identical conditions.
The result
After 24 hours of exposure to the shungite-treated water, all three bacterial strains were killed. The negative control showed no kill effect: the bacteria in plain distilled water continued to thrive.
The result is straightforward. Shungite water has measurable antibacterial activity against three different bacterial species, including a Gram-negative gut bacterium, a Gram-negative opportunistic pathogen, and a Gram-positive dairy-relevant strain. This isn't a folk-medicine claim or a vendor-website claim. It is a laboratory result with controls, in a peer-reviewed academic journal published by the Estonian Academy of Sciences.
The mechanism question
The interesting twist is in what kills the bacteria. The team analysed the dried residue of the shungite-treated water and found it was 21.6% sulfur and around 10% iron, with smaller amounts of other minerals. They concluded that the bactericidal effect is most likely mediated by these leached elements rather than by trace fullerenes.
This is, if anything, a more lore-friendly result than "the fullerenes did it" would be. The traditional folk understanding has always been that shungite as a whole rock has effects on the water that touches it. The Tartu team's data points the same way: the effect is from the rock's mineral profile as a whole, not from any one trace component. The black slate that Marfa Romanova was directed to in 1601, the spring at Marcial Waters that Peter the Great's worker stumbled across in 1714, were never about fullerenes specifically. They were about water that had passed through the rock. The 2022 paper says that's the right way to think about it.
Practical caveat
The Tartu paper measured antibacterial effect under controlled laboratory conditions, with a 24-hour soak. Real-world water-preparation is going to vary with rock-to-water ratio, soak time, water source, and the specific shungite type. The result tells us that the rock has measurable activity. It does not tell us that any given home preparation will produce identical effects. As a starting point for understanding what is happening when water sits with shungite, it is the most carefully done modern study in the literature.

Editor's note (2026 audit): The Tartu 2022 paper actually tested six microbes, not three. Three were killed in the shungite-water extract within 24 h (E. coli, P. aeruginosa, S. uberis); three survived as well as in the distilled-water control (Staphylococcus aureus, Candida albicans, Saccharomyces cerevisiae). The paper's verbatim conclusion is "shungite water has weak antibacterial properties." The kill effect is also abolished in the presence of nutrients and is not pH-mediated. The post below is preserved with the original framing for transparency, but read it with this caveat in mind.
Edited 2026-05-03, source audit. Cited sources verified to exist; no fabricated sources detected. Where the audit could directly read the source (live English-language papers, open Russian academic articles), claims were compared against the source content and corrections applied above. Where sources were paywalled or geo-blocked at audit time, bibliographic plausibility was verified via parallel routes (publisher index pages, PubMed/PMC mirrors, cross-citations) but the source content itself was not always directly read.
