How to prepare for Schlaf Ernährung

Preparing for sleep-supportive nutrition („Schlaf Ernährung“) should be evidence-based and personalized. Magnesium may improve sleep quality, but the safe upper limit for supplements is about 350 mg/day; toxicity is rare but possible with kidney issues or high doses (review, PMID: PMC13009017). General recommendations include consistent sleep schedules, avoiding caffeine and heavy meals before bed, and ensuring adequate tryptophan intake (e.g., from milk, oats, bananas). DNA tests for sleep-related genes (e.g., CLOCK, PER) have limited predictive value and should not drive drastic dietary changes. The evidence is mostly practice-based and not strongly supported by clinical trials. Caveat: consult a physician before taking supplements, especially during pregnancy or with underlying conditions.
