Nehls claims 90 percent of all chronic diseases, the pharmaceutical industry's largest market, are rooted in chronic inflammation, for which lithium is the natural antidote.

Moving from history to theory, Nehls introduces the law of the minimum: discovered in 1828 by a German agricultural scientist, it holds that biological growth is constrained by the scarcest essential input. Applied to the human brain, it means that no amount of protein or potassium can compensate for a deficiency of lithium or omega-3 fatty acids. Nehls says this law is deliberately absent from medical education because it exposes the entire pharmaceutical model as a misdirection: chronic diseases are not random genetic misfortunes but the predictable outcomes of specific deficiencies. A drug that mimics lithium's effects ('a lithium mimetic') can never outperform actual lithium, so Big Pharma must simultaneously develop such drugs and prevent patients from discovering the simple solution. He says med school taught him three things: humans are failures of nature, they inevitably get sick, and only drugs can save them — a dogma he now sees as the product of pharmaceutical capture of medical education.
Discovered in 1828 by a German agricultural scientist, the law of the minimum states that growth is constrained by the scarcest essential nutrient. Nehls applies it directly to the brain: no matter how much protein you eat, if lithium or omega-3s are missing, the hippocampus cannot grow.
The hippocampus should grow throughout life, but modern lifestyles shrink it by 1.4% per year. After 30-40 years, it is half its peak size. This measurable shrinkage is the biomarker for approaching Alzheimer's — and it begins long before any diagnosis.
In modern societies, the hippocampus shrinks by an average of 1.4% per year by volume, so after 30-40 years it is roughly half the size it was at age 25.
Making the first hour of your day high-cortisol and the last hour low-cortisol is described as the single most impactful daily habit for mood, focus, alertness, stress resilience, and sleep quality.
A Washington University in St. Louis study found that a great night's sleep produces attention-improvement effects effectively equal to Ritalin.
In the 4 to 6 hours after exercise, dopamine and norepinephrine are elevated, making you more alert and better able to focus — unless you've exercised to exhaustion.
The physiological sigh — two big inhales followed by a full exhale — was discovered by physiologists in the 1930s and is the fastest way to reduce autonomic arousal.
Doing just 10 deliberate exhales throughout the day can significantly elevate heart rate variability by the evening, by repeatedly activating the vagal sinoatrial node pathway.
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.
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 two injections of approximately 100–200 micrograms of BPC-157 eliminated persistent shoulder pain that had resisted months of other interventions.
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.
