Ray Peat explains that thyroid hormone is not a stimulant but corrects sleep disorders caused by hypothyroidism. In hypothyroidism, elevated adrenaline, estrogen, and cortisol with low magnesium disturb deep sleep. T3 with magnesium reliably treats insomnia, cramps, and anxiety. Cited sleep study shows hypothyroid patients have significantly decreased stage 3 and 4 (deep) sleep, which increases after desiccated thyroid treatment. Deep sleep stages essential for physical restoration, immune support, tissue repair, and growth hormone release.

Salt, glycine, CO2, progesterone, thyroid hormone and sugar optimize energy and sleep as restorative background processes (Ray Peat quote).

DHEA increases 11β-HSD2 enzyme activity, which locally inactivates cortisol to cortisone at the tissue level, independent of blood cortisol levels. This reduces cortisol's receptor activation in tissues. Elevated tissue-level cortisol, even with normal blood levels, contributes to insulin resistance, visceral fat, dyslipidemia, hypertension, cardiovascular disease, neurodegeneration, depression, anxiety, sleep impairment, immune suppression, poor wound healing, osteoporosis, muscle wasting, hormone dysregulation, and skin deterioration. Optimal DHEA dosing is 3-5 mg, 1-3 times daily. Higher doses become estrogenic; topical application combined with pregnenolone maximizes anti-cortisol effects while minimizing estrogen conversion. Coffee, aspirin, and vitamin D reduce activity of the related 11β-HSD1 enzyme.

Creatine supplementation is primarily marketed for muscle but has stronger evidence for brain effects. Meta-analyses show creatine improves memory and processing speed, especially in sleep-deprived, vegetarian, and older adults. Brain creatine stores deplete under stress, sleep loss, and cognitive load. Single high-dose creatine during sleep deprivation partially recovered cognitive performance and brain energy markers for ~9 hours. Vegetarians show largest cognitive gains because dietary creatine comes from meat. Protocol: 5g creatine monohydrate daily, $10/month.
