Nutritional interventions, including specific nutrients and dietary patterns, improve sleep quality and manage sleep disorders.

This review synthesizes evidence from clinical trials and observational studies over the past two decades, indicating that nutrients like magnesium, tryptophan, and omega-3 fatty acids, along with dietary patterns such as the Mediterranean diet, enhance sleep outcomes. Functional foods like tart cherry juice and kiwifruit show potential benefits, and the gut microbiome is identified as a key regulator of sleep physiology.

Mechanism Graph

Specific nutrients (e.g., magnesium, tryptophan) modulate neurotransmitter synthesis and receptor activity
↓
Anti-inflammatory and antioxidant compounds in dietary patterns reduce oxidative stress and inflammation
↓
Gut microbiome modulation via probiotics/prebiotics influences the gut-brain axis
↓
Result: Improved sleep regulation and quality

Limitations

  • ⚠The review synthesizes existing evidence without providing quantitative effect sizes or specific dose recommendations
  • ⚠Personalized nutrition approaches are discussed but lack validation from large-scale clinical trials

Frequently Asked Questions

Which nutrients are most effective for improving sleep?▼

Magnesium, tryptophan, and omega-3 fatty acids are highlighted as key sleep-supportive nutrients in this review.

Can dietary patterns like the Mediterranean diet help with sleep disorders?▼

Yes, the review suggests that dietary patterns rich in anti-inflammatory and antioxidant compounds, such as the Mediterranean diet, can improve sleep outcomes.

What functional foods are recommended for better sleep?▼

Tart cherry juice and kiwifruit are mentioned as functional foods with potential benefits for sleep quality.

How does the gut microbiome affect sleep?▼

The gut microbiome is identified as a significant regulator of sleep physiology, and probiotics/prebiotics are proposed as novel interventions to modulate sleep via the gut-brain axis.
