Food-derived bioactive compounds (FBCs) modulate sleep via a periphery-to-center axis involving gut microbiota, peripheral clocks, BBB integrity, and glia-neuron communication.

This review proposes that FBCs (amino acids, polyphenols, fatty acids, bioactive peptides, melatonin/indole derivatives) improve sleep by acting through a multi-step pathway: peripheral signal perception (gut microbiota and circadian clocks), BBB translocation/integrity modulation, and central integration via glial cell reprogramming. Glial cells are highlighted as active regulators of sleep homeostasis, and FBCs may synchronize peripheral clocks, reinforce BBB tight junctions, and mitigate neuroinflammation to restore sleep architecture.

Mechanism Graph

FBCs interact with gut microbiota and peripheral circadian clocks, sending signals to the brain
↓
FBCs cross the blood-brain barrier (BBB) or modulate BBB tight junction integrity
↓
FBCs reprogram glial phenotypes (astrocytes, microglia, oligodendrocytes) to reduce neuroinflammation
↓
Glial-neuron communication is restored, leading to improved sleep architecture and circadian rhythm

Limitations

  • ⚠This is a narrative review, not a systematic meta-analysis, so no quantitative effect sizes are provided
  • ⚠The proposed mechanism is largely based on emerging evidence, which may not be fully validated in human trials
  • ⚠Specific FBCs and doses are not detailed, limiting practical application

Frequently Asked Questions

What are food-derived bioactive compounds (FBCs) that can improve sleep?▼

FBCs include amino acids (e.g., tryptophan), polyphenols, fatty acids (e.g., omega-3), bioactive peptides, and melatonin/indole derivatives. They are natural compounds found in foods that may modulate sleep through various pathways.

How do food-derived bioactive compounds affect sleep?▼

FBCs act through a periphery-to-center axis: they influence gut microbiota and peripheral circadian clocks, cross or strengthen the blood-brain barrier, and modulate glial cells to reduce neuroinflammation, ultimately restoring sleep architecture.

Are glial cells important for sleep regulation?▼

Yes, emerging evidence shows that glial cells (astrocytes, microglia, oligodendrocytes) are active regulators of sleep homeostasis and circadian rhythms, not just passive support cells. FBCs may reprogram these cells to improve sleep.

Can functional foods with FBCs replace traditional sleep medications?▼

FBCs offer a promising non-pharmacological alternative, but more research is needed to establish specific doses and efficacy. They may be used as adjuncts or for mild sleep issues, but not as replacements for prescribed treatments without medical advice.
