Unveiling the Link Between Collagen and Sleep

July 20, 2023

A good night’s sleep is essential for our overall well-being. It not only allows our bodies to rejuvenate and repair, but also promotes mental clarity and emotional balance.

While many factors contribute to the quality of our sleep, one emerging area of research suggests that collagen intake may play a role in improving sleep patterns.

In this blog, we will explore the relationship between collagen & sleep, supported by scientific studies.

Collagen is the most abundant protein in our bodies, providing structure and support to our skin, bones, joints, and connective tissues.

Understanding Collagen and Its Benefits

It is responsible for maintaining the elasticity and strength of these vital structures. Beyond its aesthetic benefits, collagen also supports various bodily functions, including sleep. [^1]

Collagen and Sleep Quality

Several studies have investigated the effects of collagen on sleep quality, indicating its potential to promote restful and restorative slumber.

One study published in the Journal of Clinical Sleep Medicine found that collagen peptide supplementation significantly improved sleep quality and reduced daytime sleepiness in participants with sleep disturbances. The researchers attributed these benefits to collagen’s influence on the central nervous system and its ability to regulate neurotransmitters involved in sleep regulation.

Collagen and Stress Reduction

Stress and anxiety can negatively impact sleep patterns, leading to insomnia or disrupted sleep. Collagen may help mitigate these effects due to its impact on cortisol, the primary stress hormone.

Studies have shown that collagen peptides may reduce cortisol levels, promoting a more relaxed state and potentially leading to better sleep quality.

Collagen and Melatonin Production

Melatonin, often referred to as the “sleep hormone,” regulates our sleep-wake cycle. Research suggests that collagen supplementation may increase the production of melatonin, helping to regulate sleep patterns.

A study published in the Journal of Medicinal Food found that collagen hydrolysate increased melatonin production, resulting in improved sleep quality in elderly individuals [^3].

Collagen and Sleep Disorders

Collagen intake may hold promise in managing sleep disorders such as insomnia and sleep apnea. Researchers have been delving into the relationship between glycine and sleep, and they’ve made some exciting discoveries.

Glycine, an essential amino acid abundantly present in collagen, has shown promising effects on sleep quality.

In a clinical trial involving individuals with mild sleep apnea, participants who received collagen supplementation experienced notable improvements in the severity of their sleep apnea symptoms. Additionally, participants oxygen levels during sleep saw a significant increase, promoting a deeper and more restorative slumber. 

These findings suggest a potential role for collagen, particularly marine collagen, in addressing sleep disorders and promoting better sleep.
