How this protocol works

In plain language

Quality sleep is essential for physical recovery, cognitive function, immune health, and emotional wellbeing. Poor sleep is linked to obesity, diabetes, heart disease, depression, and reduced lifespan. If you struggle to fall asleep, stay asleep, or wake unrefreshed, these supplements can help support healthy sleep patterns.

  • Melatonin is the hormone your body produces to signal bedtime. Supplementing with melatonin can help reset your circadian rhythm, reduce the time it takes to fall asleep, and improve overall sleep quality. It's particularly effective for jet lag, shift work, and delayed sleep phase. Start with a low dose (0.5-1mg)—more isn't always better, and some people respond best to very low doses. Take 30-60 minutes before your desired bedtime.
  • Magnesium is involved in over 300 enzymatic reactions, including those that regulate sleep. It helps activate the parasympathetic nervous system (rest and digest), regulates melatonin production, and binds to GABA receptors to quiet the nervous system. Many people are deficient, and supplementation consistently improves sleep quality, especially in older adults. Glycinate and threonate forms are best for sleep (and less likely to cause GI issues).
  • Glycine is an inhibitory neurotransmitter that promotes sleep through an interesting mechanism—it lowers core body temperature, which is a natural signal for sleep. Studies show 3g before bed improves sleep quality, reduces daytime sleepiness, and enhances cognitive performance the next day. It has a mildly sweet taste and can be taken in water.
  • L-Theanine promotes relaxation without sedation by increasing alpha brain waves—the same state achieved during meditation. It boosts GABA, serotonin, and dopamine while reducing anxiety. It helps quiet a racing mind that prevents sleep onset. Can be combined with other sleep supplements safely.
  • Valerian Root has been used as a sleep aid for centuries. It works through GABA-ergic mechanisms to promote relaxation and sleep. Studies show it can improve sleep quality and reduce the time to fall asleep, though effects may take 2-4 weeks of regular use to fully manifest.
  • Ashwagandha improves sleep by reducing cortisol (the stress hormone that can keep you awake) and promoting calmness. It also contains triethylene glycol, a compound that may directly promote sleep. Particularly useful if stress or anxiety interferes with your sleep.
  • Tart Cherry Extract is a natural food source of melatonin. Studies show tart cherry juice increases sleep time and quality. It also contains anti-inflammatory compounds that may contribute to its sleep benefits.

Expected timeline: Melatonin works immediately (first night). Glycine and theanine: immediate effects. Magnesium: 1-2 weeks for full benefit. Valerian: 2-4 weeks. Ashwagandha: 2-4 weeks for cumulative effects.
