MyBody-X angle on Schlaf Ernährung

MyBody-X does not offer a specific 'sleep nutrition' analysis beyond general associations. Available DNA markers (e.g., PER3 for chronotype, CLOCK for circadian rhythm) have small effect sizes and are insufficient to personalize dietary recommendations for better sleep. While nutrients like tryptophan, magnesium, or melatonin can influence sleep, genetic predisposition is complex and poorly covered by consumer tests. The evidence for such tests is therefore rated as 'marketing' or 'unclear'. For improving sleep through diet, proven strategies like consistent sleep schedules, reducing evening caffeine, and a balanced diet are more reliable. A DNA test can provide only limited guidance and should not replace medical advice for sleep disorders.
