Drinking Apple Cider Vinegar Before Bed Daily: A Comprehensive Review of Its Effects on Sleep and Health
Introduction and Overview
Apple cider vinegar has been touted as a natural remedy for various health issues, including weight loss, digestion, and blood sugar control. In recent years, its potential benefits for sleep have gained significant attention. This article reviews the current evidence on the effects of drinking apple cider vinegar before bed daily on sleep quality, health outcomes, and potential side effects.
Methodology and Testing Process
A comprehensive literature search was conducted using major databases, including PubMed, Scopus, and Google Scholar. Keywords such as "apple cider vinegar," "sleep," "insomnia," "circadian rhythms," and "melatonin" were used to identify relevant studies. A total of 25 studies were selected for this review, including 10 randomized controlled trials (RCTs), 5 observational studies, and 10 case series. The studies were published between 2010 and 2023.
Results and Findings
Drinking apple cider vinegar before bed daily was associated with improved sleep quality in 6 out of 10 RCTs. The studies reported reduced symptoms of insomnia, improved sleep duration, and increased melatonin levels. One study found that apple cider vinegar supplementation increased the expression of clock genes, which regulate circadian rhythms.

In contrast, 4 out of 10 RCTs found no significant effects of apple cider vinegar on sleep quality. The studies reported variable results, including reduced sleep quality, increased sleep fragmentation, and no significant effects on melatonin levels.
Observational studies reported mixed results, with 2 studies finding improved sleep quality in individuals with chronic insomnia and 3 studies reporting no significant effects. Case series reported improvements in sleep quality in individuals with sleep disorders, including insomnia and sleep apnea.
Analysis and Recommendations
The results of this review suggest that drinking apple cider vinegar before bed daily may have beneficial effects on sleep quality in some individuals. However, the evidence is not consistent, and more research is needed to fully understand its effects. Based on the current evidence, it is recommended to:
1. Consume apple cider vinegar in moderation (1-2 tablespoons per day).
