topicGlycine Performance Recovery Randomized Trial
claimEvidence on NAC suggests context-dependent effects, with supplementation improving glutathione availability, fatigue resistance, and exercise performance in individuals with low baseline glutathione, while results remain inconsistent in healthy populations.

topicGlycine Performance Recovery Randomized Trial
claimFailure to meet the recommended 7-9 hours of restful sleep per night is known to increase the risk of several health conditions, reason why regular and adequate sleep should be seen as a priority instead of an unnecessary commodity easily traded as required by the commitments of our busy lives.

topicGlycine Performance Recovery Randomized Trial
claimWhile both the quantity and the quality of sleep can be largely improved with relatively straightforward practices dictated by good sleep hygiene, emerging research suggests that dietary and supplementation protocols focused on certain foods, nutrients, and biochemical compounds with sleep-promoting properties can act as subsidiary sleep aids in complementing these behavioral changes.

claimThe scope of this narrative review is to summarize the available evidence on the potential benefits of selected nutraceuticals in the context of circadian rhythm and sleep disturbances, namely melatonin, magnesium, omega-3 fatty acids, tart cherry juice, kiwifruit, apigenin, valerian root, L-theanine, glycine, ashwagandha, myoinositol, Rhodiola rosea, and phosphatidylserine.
