Exploring Magnesium and Glycine for Better Sleep

After spending three years delving into the topic of sleep, I’ve recently jumped on the magnesium bandwagon, intrigued by its reputation for enhancing deep sleep. But it makes me wonder, how does it compare to glycine, which is also touted for sleep improvement?

Magnesium gained immense popularity after the viral sensation of the sleepy girl mocktail. Personally, I’ve started using magnesium patches and gummies every night in hopes of enjoying deeper sleep. However, upon checking the label on my gummies, I noticed they also contain glycine, marketed as a way to “support relaxation.”

Key Takeaways: Glycine vs. Magnesium

• Both magnesium and glycine are known to improve sleep quality and help with falling asleep.
• Magnesium has more substantial evidence supporting its ability to increase deep sleep duration, but this can depend on individual magnesium levels.
• Although there’s limited evidence that glycine specifically enhances deep sleep, it may be more beneficial for falling asleep quickly and feeling less groggy in the morning.
• For optimal results, both supplements should be taken about an hour before bed. Magnesium can be consumed with food to minimize digestive discomfort, while glycine is more effective when mixed with water in powder form.

How Glycine Improves Sleep

The gummies I’m taking are intended to promote a sense of calm and overall well-being, with glycine as a primary ingredient. But, just what is glycine, and how can it help with sleep?

“Glycine is an amino acid, a fundamental building block of protein, that has implications for brain function,” explains Dr. Sarah Jamison, a board-certified doctor and member of the Vitamin Shoppe’s Wellness Council.

Dr. Raj Dasgupta, also a certified physician, notes that glycine can potentially enhance subjective sleep quality and help with alertness the following day.

“Its value in promoting sleep lies in its ability to lower body temperature and help achieve a calmer state in the nervous system, both of which are essential for falling asleep,” he adds.

How Magnesium Improves Sleep

I’ve been incorporating magnesium supplements, going for gummies and patches at night. Both doctors affirm that magnesium is a well-established supplement for promoting sleep.

“Magnesium is crucial for regulating the chemicals in our brain that support sleep,” Dr. Jamison notes.

“Research links higher magnesium levels to better sleep quality, prolonged sleep duration, and quicker sleep onset,” she adds.

Dr. Dasgupta emphasizes magnesium’s role in stress management, referencing a 2020 review that highlighted how magnesium stabilizes the nervous system.

“People often use it for sleep because it has a calming effect that may reduce physical tension and decrease nighttime awakenings,” he explains.

Magnesium vs. Glycine: Which Is Better for Deep Sleep?

Before getting into the specifics, it’s essential to recognize that more research is needed to fully understand the impact of both supplements on deep sleep.

“Neither of these supplements guarantees a notable increase in slow-wave sleep,” Dr. Dasgupta warns.

Nonetheless, both magnesium and glycine show promise in promoting deeper sleep. Here’s a look at their respective strengths and weaknesses.

Glycine: Pros and Cons

Dr. Dasgupta acknowledges that, while research is limited, glycine may have a slight advantage based on current findings.

“Evidence suggests glycine has more direct support for enhancing sleep quality; some studies indicate modest improvements in perceived sleep depth,” he states.

Dr. Jamison points out that glycine may not have a clear impact on deep sleep, but it does aid in falling asleep and overall sleep quality.

“If your main issue is struggling to doze off or waking up feeling groggy, glycine could be a better option,” she suggests.

Magnesium: Pros and Cons

Dr. Jamison believes magnesium is the superior option for those seeking deeper sleep.

“When it comes to improving deep sleep, magnesium has stronger evidence supporting its effectiveness,” she claims.

Dr. Dasgupta agrees, noting that while magnesium can improve sleep for those who are deficient, its effects tend to be less pronounced in individuals with adequate magnesium levels.

“In those lacking magnesium, restoring normal levels can significantly enhance sleep quality, but the influence on people with normal levels is generally minimal,” he explains.

How to Take Magnesium for Sleep

While I rely on gummies and patches for my magnesium intake, there are many different options available.

Magnesium comes in various forms: tablets, capsules, powders, topical solutions, sprays, and even in hot chocolate mixes.

Dr. Dasgupta points out that choosing the right type of magnesium may be more important than merely considering the form.

He highlights magnesium glycinate as the preferable form for sleep due to its better absorption and gentleness on the stomach, while magnesium citrate can be effective too, albeit with a higher likelihood of causing digestive upset.

In terms of timing, Dr. Dasgupta suggests taking magnesium in the evening alongside a snack for better tolerance. Dr. Jamison concurs, recommending it about an hour before bed for optimal results.

It’s wise to consult a healthcare provider regarding the correct dosing, as it can vary based on individual needs.

How to Take Glycine for Sleep

Similar to magnesium, glycine also comes in multiple forms like powders, capsules, and gummies. However, Dr. Dasgupta urges choosing a form based on the dosage efficiency.

He suggests that while glycine is available in powders or capsules, powder is typically preferred due to the higher effective doses needed for sleep.

Capsules can be more convenient, but they often necessitate taking several to achieve a sufficient dose.

Dr. Jamison affirms that the individual needs may affect the appropriate dosage and form, but a typical healthy adult’s dose is approximately 3g of glycine.

Ultimately, both doctors recommend taking glycine about 30 to 60 minutes before bedtime for the best impact.

So, whether I lean toward magnesium or glycine as my go-to nighttime companion, it seems both could positively contribute to my nighttime routine.
