300 µg lithium stabilized Alzheimer's for 15 months

Harvard's Nature Study and Alzheimer's Reversal
At 1:06:30 · chapter starts 59:15
Six weeks after Nehls's European Parliament speech, Nature published a bombshell: Harvard researchers analyzed 28 trace elements in the post-mortem brains of Alzheimer's patients and found that only lithium deficiency significantly correlated with disease stage. They then tested genetically engineered Alzheimer's-prone mice: the animals don't develop the disease under good conditions, but removing lithium from their diet triggers it. Restore the lithium, and the disease disappears. This is, Nehls argues, direct mechanistic confirmation of his Unified Theory of Alzheimer's, published in 2016. He then addresses the reversal question: in early-stage Alzheimer's, when the hippocampus is still partially intact, restoring neurogenesis through lithium and other nutritional interventions can stop and even reverse the progression — just as type 2 diabetes can be reversed by lifestyle. Meta-analyses already show that 300 micrograms of lithium per day (less than one full milligram) stabilized Alzheimer's patients for 15 months while controls deteriorated.
Harvard's Nature Study: Only Lithium Predicts Alzheimer's Severity
A Harvard-linked study published in Nature in August 2025 analyzed 27-28 trace elements in the brains of deceased Alzheimer's patients. Of all of them, only lithium deficiency correlated significantly with disease severity.
Alzheimer's Can Be Reversed in Early Stages
Meta-analyses show even 300 micrograms of lithium per day — less than a full milligram — stabilized Alzheimer's patients for 15 months while untreated patients declined. Nehls argues comprehensive nutritional intervention can reverse early-stage disease entirely.

Nicotine performance dose: 3–6mg, max 2x/week
For nicotine to have a genuine cognitive-enhancing effect rather than merely rescuing withdrawal deficit, Huberman recommends using it only once or twice per week at 3–6 mg.
Vaping = higher total nicotine than smoking
Because vaping can be done anywhere and is more palatable, people consume far more nicotine via vaping than they ever did smoking, potentially making vaping more dangerous in aggregate despite being safer per puff.

Huberman reported that on nights he used the peptide pinealon, he achieved 2.5 to 3 hours of REM sleep inside 6 hours — an unusually high proportion normally only found in the final hours of longer sleep.
