The Science of Sleep Supplements: Insights from Peter Attia

Quality sleep is essential for overall health, yet many struggle with insomnia or poor sleep. Dr. Peter Attia, a renowned longevity expert, emphasizes the importance of optimizing sleep through both behavioral changes and, when necessary, evidence-based supplements. Here’s a breakdown of key sleep supplements and their benefits, based on Attia’s insights.

1. Magnesium (Glycinate or Threonate)
Magnesium plays a crucial role in relaxation and nervous system regulation. Attia recommends magnesium glycinate or threonate for their high bioavailability and calming effects. These forms help reduce cortisol levels and improve sleep quality without causing digestive discomfort.

2. Melatonin (Low Dose)
Melatonin, the body’s natural sleep hormone, can be supplemented in small doses (0.3–1 mg) to regulate circadian rhythms. Attia cautions against high doses, which may disrupt natural production. It’s best used for jet lag or occasional sleep disturbances.

3. L-Theanine
Found in green tea, L-theanine promotes relaxation without drowsiness. Attia suggests 100–400 mg before bed to enhance GABA activity, reducing anxiety and improving deep sleep.

4. Apigenin
A flavonoid in chamomile, apigenin acts as a mild sedative by binding to GABA receptors. Attia highlights its potential in reducing nighttime awakenings when taken in doses of 50–100 mg.

5. Glycine
This amino acid lowers core temperature, a key factor in sleep onset. Attia recommends 3–5 grams before bed to improve sleep efficiency and reduce fatigue upon waking.

6. CBD (Cannabidiol)
For those with anxiety-related insomnia, low-dose CBD (10–25 mg) may help by modulating stress responses. Attia notes its potential but advises caution with long-term use due to limited research.

Final Thoughts
While supplements can aid sleep, Attia stresses that they should complement—not replace—good sleep hygiene. Prioritize consistent sleep schedules, a dark/cool environment, and reduced blue light exposure before bed. Always consult a healthcare provider before starting new supplements.

By integrating these science-backed supplements with healthy habits, you can optimize sleep for better cognitive function, longevity, and overall well-being.
