AMA #15: Fluoride Benefits/Risks & Vagus Nerve Stimulation

About this video

In this AMA, Huberman tackles fluoride’s benefits and risks alongside vagus nerve stimulation. On fluoride, Huberman stresses that the dose makes the poison: he cites the CDC’s recommended level of 0.7 milligrams per litre in drinking water as intended to prevent tooth decay, and advises listeners to check their own tap water, noting total exposure depends on how much water someone drinks and on body weight, so children receive a proportionally larger dose. He says high levels of fluoride have been shown to disrupt thyroid metabolism and that neurotoxicity has been hypothesised, though he characterises that evidence as highly debated and largely from studies in dishes rather than people. He outlines the spectrum from unconcerned to very concerned consumers and how each might respond.

Key takeaways

• Huberman stresses that with fluoride, the dose makes the poison.
• Huberman cites the CDC recommended level of 0.7 milligrams per litre for drinking water.
• Huberman advises checking your local tap water fluoride level and weighing total intake against body weight.
• Huberman says fluoride neurotoxicity is hypothesised but highly debated, with much evidence from in vitro studies.
