Fluoridated water

Andrew Huberman discusses various aspects of fluoridated water in several episodes of the Huberman Lab. Here are the key takeaways:

1. Health Concerns:

   • High concentrations of fluoride in drinking water can potentially disrupt thyroid hormone metabolism and usage. However, the degree of risk depends on the dosage—the expression "the dose makes the poison" is applicable here. The CDC recommends a safe level of 0.7mg/l to prevent tooth decay while also being considered safe 1.
   • If fluoride levels are too high, they can be harmful, potentially affecting thyroid and brain health. It is particularly a concern at concentrations higher than what the CDC has deemed safe 2.

2. Benefits:

   • Fluoride is added to strengthen teeth and prevent cavities. It chemically strengthens the mineral bonds in teeth, making them more resistant to decay 3.

   • The practice of adding fluoride to water began as a cost-effective public health measure to reduce tooth decay and has been widely accepted for its benefits to dental health 4.

3. Public and Legal Response:

   • There is a significant divide in public opinion about fluoridated water, evidenced by ongoing lawsuits in California and New York. These lawsuits reflect the polarized views on whether fluoride should be in the water supply 5.

4. Personal Choice and Actions:

   • For those concerned about fluoride intake, filtering tap water is an effective way to reduce or eliminate fluoride exposure. Filters that remove fluoride are available, and some people choose to use comprehensive home filtration systems to ensure their water is fluoride-free 6.

5. Recommendations:

   • If unsure about the fluoride levels in your water, testing your tap water or checking local water reports is advisable. Andrew Huberman provides links for checking fluoride levels in drinking water in the episode notes for his discussions on this topic.
