Synopsis
Source of validity: Scientific
Rating (out of 5): 2
Zinc has been investigated for its role in sleep regulation and the potential to support or treat insomnia. Several observational studies have found correlations between serum zinc levels and sleep quality. For example, a 2017 review in Biological Trace Element Research summarized evidence suggesting that higher zinc levels are associated with improved sleep efficiency and duration, particularly in children and adolescents. Experimental studies, such as a 2011 clinical trial published in European Journal of Clinical Nutrition, found that supplementation with zinc, often in combination with other nutrients like magnesium and melatonin, improved self-reported sleep quality in older adults. Animal studies also suggest that zinc can modulate the central nervous system and may influence neurotransmitters involved in sleep regulation, such as GABA and glutamate. However, the evidence remains limited and somewhat inconsistent. Most human studies are small, observational, or use zinc as part of a multi-nutrient supplement, making it difficult to isolate the effect of zinc alone. Systematic reviews note a lack of large-scale randomized controlled trials directly assessing zinc monotherapy for insomnia. Thus, while there is preliminary scientific interest and some suggestive data, the overall evidence supporting zinc as a treatment for insomnia is weak to moderate and does not reach the level of strong clinical validation. Zinc supplementation may be helpful for individuals with deficiency, but its routine use for insomnia is not currently supported by robust clinical evidence.
