Trouble Sleeping? Try this Supplement. (No, not melatonin)

Summary

In this insightful discussion, glycine is highlighted as a beneficial amino acid for improving sleep quality. It acts as a neurotransmitter, facilitating communication between neurons and promoting vasodilation, which aids in lowering body temperature essential for sleep. Research indicates that glycine can reduce fatigue and enhance subjective sleep quality, though effects on sleep architecture show slight decreases in deep sleep and increases in REM sleep. While it is not a cure-all, taking 3 grams about an hour before bed may significantly improve sleep onset and duration, making glycine a promising supplement for those struggling with sleep issues.

Q & A

What is glycine and how does it relate to sleep?

Glycine is an amino acid that acts as a neurotransmitter in the brain. It is believed to aid sleep by binding to NMDA receptors, which helps regulate ion concentrations and promotes vasodilation, contributing to lower body temperature needed for sleep.

How does glycine affect body temperature during sleep?

Glycine facilitates vasodilation, allowing blood vessels to relax and increase blood flow to the surface of the skin. This process helps in expelling heat, which is essential for the body's temperature to drop as one falls asleep.

What type of studies were conducted to assess glycine's effects on sleep?

The studies mentioned in the transcript were placebo-controlled and randomized trials, designed to evaluate the effects of glycine on individuals experiencing sleep difficulties.

What were the key findings regarding glycine's impact on subjective fatigue?

Participants in the studies reported a significant reduction in subjective fatigue after taking glycine, indicating an improvement in their feelings of tiredness.

Did glycine have any impact on actual sleep architecture?

Yes, glycine was found to slightly reduce deep sleep while potentially increasing REM sleep. However, the changes in sleep architecture were not substantial.

How long before bedtime should glycine be taken for optimal effects?

Glycine should typically be consumed about one hour before sleep to achieve the best results in improving sleep quality.

What dosage of glycine was commonly used in the studies?

The typical dosage used in the studies was 3 grams of glycine taken before sleep.

What are some limitations of the research on glycine and sleep?

The main limitations include the small number of studies (four) and the fact that most were funded or linked to industry, which may influence the results and perceptions of efficacy.

Can glycine be considered a cure-all for sleep disorders?

No, glycine is not a cure-all. While it can help improve sleep quality and reduce feelings of fatigue, its effects are modest and may vary among individuals.

What resources does the speaker offer for further understanding of health research?

The speaker mentions a health autonomy course that teaches how to analyze scientific studies and apply findings to personal health, helping individuals discern the validity of various health-related claims.
