Risk reduction increases with consumption: 1 cup daily reduces cirrhosis risk by ~50%; 4 cups daily by ~84%. In advanced liver scarring, those drinking 3+ cups daily had ~43% lower rates of liver failure or cancer compared to non-drinkers. Tea and other caffeine sources showed no benefit.

Hypothyroidism reduces CO₂ production because mitochondrial CO₂ production depends on thyroid hormone T3. End-tidal CO₂ measurement reflects alveolar and arterial CO₂ levels. Contrary to expectations, hypothyroid patients show higher alveolar ventilation (lower end-tidal CO₂), indicating hyperventilation rather than hypoventilation. The mechanism may involve direct effects of TRH on respiratory center or local lung changes. Respiratory rate alone does not define hypo/hyperventilation; arterial CO₂ is the definitive measure.

Untreated hypothyroidism increases anxiety risk nearly 4-fold. Mechanisms include elevated histamine, catecholamines (adrenaline and noradrenaline), cortisol, lactate, hyperventilation, and reduced CO₂ production. A case study shows severe psychiatric manifestations (delusions, hallucinations, insomnia, anxiety, disorganized speech) in a hypothyroid patient (TSH >100) that resolved within one day of levothyroxine initiation and remained absent at 6-month follow-up without psychotropic medications.

lowmegatron comments that T3 is not an antidepressant, but that many depression cases reflect low brain energy. He claims optimizing brain T3 normalizes ATP production and that TSH and T4 tests cannot reliably infer T3. He warns T3 is a metabolic stimulant that can be dangerous in excess, especially with heart issues. He also argues the standard 25 mcg+ once-daily research doses are suboptimal and that more physiological dosing would likely improve results.

Creatine supplementation is primarily marketed for muscle but has stronger evidence for brain effects.

Vegetarians show largest cognitive gains because dietary creatine comes from meat. Protocol: 5g creatine monohydrate daily, $10/month.
