Sleep Disruptions? Use This Supplement to Stop It

Sleep disruptions is a common complaint that many people experience, often resulting in disrupted sleep and overall fatigue the next day. This phenomenon is often linked to high cortisol levels, the body’s primary stress hormone, which can interfere with the body’s natural sleep-wake cycle. But what if there was a simple supplement that could help combat this issue? The answer might lie in glycine, an amino acid that has been shown to help reduce cortisol levels and improve sleep quality. In this blog post, we will explore how glycine works to address high cortisol and why it may be the key to solving your 3AM wake-ups.

Key Summary Takeaways 

• Main Problem: Waking up at 3AM is commonly caused by an acute rise in cortisol (the stress hormone) during the night, which interferes with melatonin and disrupts the natural sleep-wake cycle.
• Root Cause: Elevated nighttime cortisol from stress, poor sleep habits, or hormonal imbalance prevents deep, uninterrupted sleep.
• Recommended Supplement: Glycine — a non-essential amino acid that lowers cortisol, improves sleep onset, deepens sleep, and stabilizes circadian rhythm.
• How Glycine Works:
  • Significantly reduces cortisol secretion, especially under stress (supported by Saito et al. 2008).
  • Improves sleep quality and helps people fall asleep faster (Yamadera et al. 2007).
  • Calms the central nervous system and synchronizes circadian rhythm (Wang et al. 2018).
• Dosage & Timing: Take 3 to 5 grams of glycine about 30–60 minutes before bedtime, consistently every night.
• Best Results Tip: Pair glycine with relaxation practices like deep breathing, meditation, or light stretching.
• Alternative/Complementary Option: Ornithine (especially during a parasite cleanse or if liver health is an issue) — helps remove excess ammonia, supports liver detoxification, and reduces nighttime restlessness around 2–3AM.
• Liver Connection: According to Traditional Chinese Medicine (TCM), waking at 3AM often signals a liver imbalance; a liver cleanse may help alongside supplementation.
• Expected Outcome: Deeper, uninterrupted sleep, reduced early-morning alertness, and better overall energy the next day when cortisol is properly regulated.

Understanding the Role of Cortisol in Sleep Disruptions

Cortisol is often referred to as the "stress hormone" because it is released during periods of stress, triggering the body's fight-or-flight response. However, cortisol also plays an important role in regulating the circadian rhythm, or the body’s internal clock. Under normal circumstances, cortisol levels peak in the morning to help you wake up and start your day. However, when cortisol levels remain elevated during the night, it can lead to disturbances in sleep, especially during the early morning hours.

Many people who wake up at 3AM often experience an acute rise in cortisol, which leads to feelings of alertness and makes it difficult to return to sleep. This spike in cortisol can be triggered by various factors, including stress, poor sleep habits, or an imbalance in the body’s production of hormones. High cortisol levels can interfere with the production of melatonin, the hormone responsible for sleep, making it harder for individuals to fall and stay asleep.

The Glycine Solution

Glycine is a non-essential amino acid that plays a critical role in the body’s biochemical processes, including protein synthesis and the regulation of the central nervous system. Research has shown that glycine has several beneficial effects on sleep, particularly in the context of reducing cortisol levels and improving sleep quality.

Glycine Reduces Cortisol Levels

One of glycine’s most important benefits is its ability to help lower cortisol levels. Studies have shown that glycine supplementation can significantly reduce cortisol secretion, particularly during periods of stress. For example, a study published in Neuropsychopharmacology found that glycine supplementation led to a decrease in cortisol levels in stressed individuals, suggesting that it could help mitigate the physiological effects of stress that often cause early morning wake-ups. A study by Saito et al. (2008) demonstrated that oral glycine supplementation in humans led to a significant reduction in cortisol secretion, particularly under stress. This reduction in cortisol levels could directly help reduce the chances of waking up during the night or early morning hours due to heightened stress responses.

Glycine Enhances Sleep Quality

In addition to lowering cortisol, glycine has been shown to improve overall sleep quality. A study published in Sleep and Biological Rhythms found that glycine supplementation improved both sleep onset and sleep quality in individuals who had trouble sleeping. The researchers concluded that glycine might be an effective strategy for managing insomnia and promoting restful sleep by balancing cortisol and supporting the body’s natural sleep processes. A study by Yamadera et al. (2007) showed that glycine administration before bedtime helped individuals fall asleep faster and experience deeper, more restful sleep. This could be particularly useful for people who struggle with waking up at 3AM due to disruptions in their sleep cycle.

Glycine and the Circadian Rhythm

Glycine has also been linked to the regulation of the circadian rhythm. A study published in Frontiers in Neurology revealed that glycine has a calming effect on the central nervous system, which may help promote a more stable circadian rhythm. By stabilizing cortisol levels during the night, glycine can prevent the early morning spikes that often lead to waking up at 3AM. Research by Wang et al. (2018) found that glycine can help synchronize the circadian rhythm by influencing the release of neurotransmitters and hormones that govern sleep and wake cycles. This stabilization of the circadian rhythm can help prevent cortisol spikes during the night, which is a key factor in waking up prematurely.

How to Use Glycine for Better Sleep

If you're waking up at 3AM due to high cortisol, glycine could be the supplement you need. Here's how to use it:

1. Timing: Take 3 to 5 grams of glycine about 30 minutes to an hour before bedtime. This timing helps to promote relaxation and regulate cortisol levels during sleep.

2. Consistency: Like any supplement, consistency is key. Take glycine nightly to help build up its effects on cortisol regulation and overall sleep quality.

3. Pair with Relaxation Practices: For best results, combine glycine supplementation with relaxation techniques such as deep breathing, meditation, or light stretching. These practices can help further lower cortisol and prepare your body for restful sleep.

What About Ornithine?

Ornithine can also be helpful during a parasite cleanse, as it is a powerful amino acid that plays a key role in the urea cycle, the body’s natural process for removing excess nitrogen and ammonia. When ammonia builds up—often due to high protein intake, poor liver function, or parasitic activity—it can disrupt the nervous system and lead to nighttime restlessness or sudden awakenings, especially around 2–3AM when the liver is most active in detoxification. By helping convert toxic ammonia into urea, which can be safely excreted through urine, ornithine supports liver function and reduces the neurological stimulation that causes sleep disturbances. Many people find that taking ornithine before bed helps promote deeper, uninterrupted sleep and a calmer mind.

Conclusion

If you're struggling with waking up at 3AM due to elevated cortisol levels, glycine may offer a natural solution. By reducing cortisol secretion, improving sleep quality, and stabilizing the circadian rhythm, glycine can help you enjoy deeper, uninterrupted sleep. If glycine alone doesn't help much and you are doing a parasite cleanse, then ornithine was recommended for a short time by Dr. Hulda Clark. As supported by scientific research, incorporating glycine into your nightly routine (and having ornithine handy) could be the key to stopping those early morning wake-ups and improving your overall sleep health.
