Dietary and supplementation protocols focused on sleep-promoting nutraceuticals can act as subsidiary sleep aids in complementing behavioral sleep hygiene changes.

This narrative review summarizes evidence that selected nutraceuticals, including melatonin, magnesium, omega-3 fatty acids, tart cherry juice, kiwifruit, apigenin, valerian root, L-theanine, glycine, ashwagandha, myoinositol, Rhodiola rosea, and phosphatidylserine, may improve sleep quality and quantity. The paper suggests these compounds can serve as adjuncts to good sleep hygiene practices for individuals with circadian rhythm and sleep disturbances.

Frequently Asked Questions

Which nutraceuticals are most effective for improving sleep?▼

The review highlights melatonin, magnesium, omega-3 fatty acids, tart cherry juice, kiwifruit, apigenin, valerian root, L-theanine, glycine, ashwagandha, myoinositol, Rhodiola rosea, and phosphatidylserine as potential sleep aids, but does not rank their effectiveness.

Can these dietary protocols replace good sleep hygiene?▼

No, the paper states that these nutraceuticals act as subsidiary sleep aids to complement behavioral changes from good sleep hygiene, not replace them.

What is the recommended dose for these supplements?▼

The abstract does not provide specific doses; readers should refer to the full review for evidence-based protocols.

Are these nutraceuticals safe for long-term use?▼

The abstract does not discuss safety or long-term effects; individual compounds may have varying safety profiles.
