Key takeaways

Synthetic nootropics often trigger short-term reactions & deplete vital nutrients like magnesium over time

Magnesium & other minerals play a critical role in brain energy & function, yet most people remain deficient

Extreme therapies like saunas or cold plunges drain essential minerals, leading to hidden side effects

Each brain cell holds up to 2 million mitochondria, making proper nutrition essential for brain energy

Regular blood tests fail to show true magnesium status, since most magnesium resides in cells & bones

Too much calcium with too little magnesium makes bones brittle rather than stronger

Most fish oil supplements undergo heavy processing, oxidize easily & often cause harm while algae-based omega-3 offers a safer option

High doses of vitamin C support collagen, bone & artery strength far beyond the minimal RDA

Mega-dosing one nutrient (like iodine or zinc) throws off balance & depletes others your body needs

Food-based, methylated B vitamins support mental health & epigenetics better than high-dose synthetics
