DeepSummary
In this episode, Andrew Huberman discusses the presence of fluoride in drinking water and examines the reasons behind it as well as the potential health risks associated with excessive fluoride consumption. Huberman explains that fluoride was introduced in drinking water as a low-cost approach to strengthen teeth and prevent cavities by creating stronger bonds in the mineralization process of tooth enamel. However, he also acknowledges that high levels of fluoride can potentially disrupt thyroid hormone function and even cause neurotoxicity.
Huberman emphasizes that the harm caused by fluoride depends on the dosage, and recommends finding out the fluoride levels in one's tap water to determine if filtration is necessary. He shares his personal experience of accidentally ingesting a high concentration of fluoride as a child, leading to severe illness, as an illustration of fluoride's toxic potential at high doses. While recognizing the benefits of fluoride for dental health, Huberman suggests exploring alternative methods for remineralizing teeth and maintaining oral hygiene.
The episode also briefly touches upon the Huberman Lab Premium subscription, which aims to fund important scientific research on human subjects related to mental health, physical health, and performance. Huberman emphasizes that the standard podcast will remain free, and that the premium content will include transcripts, exclusive episodes, and the opportunity to contribute to scientific studies through a matching program with the Tiny Foundation.

- “If you were to ask me, I would say, yeah, I think given that the cost of most of the filters that can remove most of the fluoride is low, and given that there is some health concern of consuming too much fluoride, why not just remove fluoride from the drinking water?“ by Andrew Huberman
- “I'm hoping that clearly answers for you the question of why there is fluoride in our drinking water at all.“ by Andrew Huberman
- “But in reality, both the group of people that are doing an immense number of things to try and keep their teeth white and their breath fresh are, yes, doing things that are good for their oral health, but also no doubt damaging their oral health. In particular the oral microbiome, which is absolutely critical.“ by Andrew Huberman

Welcome to a preview of the 15th Ask Me Anything (AMA) episode, part of Huberman Lab Premium.
Huberman Lab Premium was launched for two main reasons. First, it was launched in order to raise support for the main Huberman Lab podcast — which will continue to come out every Monday at zero-cost. Second, it was launched as a means to raise funds for important scientific research. A significant portion of proceeds from the Huberman Lab Premium subscription will fund human research (not animal models) selected by Dr. Huberman, with a dollar-for-dollar match from the Tiny Foundation.
