From the Guidelines
Collagen supplementation is not a recommended treatment for improving sleep quality based on the provided evidence. The studies provided do not support the use of collagen supplements for improving sleep quality, and instead focus on other treatments such as cognitive behavioral therapy for insomnia (CBT-I) and pharmacological therapy 1.
Key Points to Consider
- The evidence provided does not mention collagen supplementation as a treatment for sleep disorders.
- CBT-I is a recommended treatment for chronic insomnia disorder, with moderate-quality evidence showing improved sleep outcomes and global outcomes in the general population and in older adults 1.
- Pharmacological therapy may be considered for adults with chronic insomnia disorder in whom CBT-I alone was unsuccessful, with a shared decision-making approach discussing the benefits, harms, and costs of short-term use of medications 1.
Recommendations for Improving Sleep Quality
- Maintain good sleep hygiene practices, such as maintaining a regular sleep schedule, creating a comfortable sleep environment, and avoiding caffeine and electronic devices before bed.
- Consider CBT-I as a treatment for chronic insomnia disorder, with a healthcare provider's guidance.
- If pharmacological therapy is considered, discuss the benefits, harms, and costs of short-term use of medications with a healthcare provider.
From the Research
Collagen Supplementation and Sleep Quality
- The relationship between collagen supplementation and sleep quality is explored in several studies 2, 3.
- One study found that good sleep quality may enhance the benefits of oral collagen supplementation for the skin, suggesting a potential link between sleep and collagen effectiveness 2.
- However, the primary focus of this study was on the effects of collagen supplementation on skin health, rather than sleep quality.
Effects of Collagen Supplementation on Sleep
- A study published in the European Journal of Nutrition found that collagen peptide supplementation before bedtime reduced sleep fragmentation and improved cognitive function in physically active males with sleep complaints 3.
- The study used a randomized, crossover design and measured sleep quality using subjective sleep diaries, actigraphy, and polysomnography.
- The results showed that collagen peptide supplementation decreased awakenings and improved cognitive function, but did not influence sleep quantity, latency, or efficiency.
Other Factors Influencing Sleep Quality
- Sleep quality can be influenced by various factors, including sleep disorders, melatonin levels, and lifestyle habits 4, 5, 6.
- Melatonin supplementation has been shown to improve sleep quality and regulate circadian rhythms 6.
- Complementary and alternative medicine interventions, such as relaxation techniques and acupuncture, may also be effective in improving sleep quality 5.
