Sleep disturbances are linked with cardiovascular and metabolic disease as well as poor body composition. To investigate the use of tart cherry supplements, which are high in antioxidants and may contain melatonin, on parameters of health such as sleep, body composition, cellular health, and blood pressure (BP). Forty-four participants had completed sleep record data and were included in this analysis. Participants consumed either two 240 ml bottles per day of Montmorency tart cherry (MTC) juice or placebo or two capsules per day of powdered MTC or placebo for 30 days. Participants tracked their sleep daily via questionnaire and completed body composition and BP assessments at baseline, 14 days, and 30 days after supplementation. There were no significant differences in sleep time or quality between groups, though both increased over 30 days. The capsule groups had significantly lower body mass (BM) 14 days versus baseline for placebo group (p = 0.01, mean difference: 0.70 kg) and at 30 days versus 14 days in MTC group (p = 0.02, mean difference: 0.75 kg). No other differences in body composition or cellular health were found. BP was unaffected by MTC supplementation over 30 days. Despite the potential benefits of antioxidants and melatonin, we did not find improvements in sleep time or quality, cellular health or BP in participants consuming MTC for 30 days, though BM decreased in capsule groups. These results conflict with previous data on MTC and sleep and BP, therefore further investigation is warranted.
睡眠障碍与心血管疾病、代谢疾病以及不良身体成分有关。为了研究富含抗氧化剂且可能含有褪黑素的酸樱桃补充剂对睡眠、身体成分、细胞健康和血压（BP）等健康参数的影响。44名参与者完成了睡眠记录数据并被纳入该分析。参与者每天饮用两瓶240毫升的蒙特莫伦西酸樱桃（MTC）汁或安慰剂，或每天服用两粒MTC粉末胶囊或安慰剂，持续30天。参与者通过问卷每天记录他们的睡眠情况，并在补充前、补充14天和30天后完成身体成分和血压评估。尽管两组的睡眠时间和质量在30天内均有所增加，但两组之间没有显著差异。与安慰剂组基线相比，胶囊组在14天时体重（BM）显著降低（p = 0.01，平均差异：0.70千克），在MTC组中，30天时与14天时相比体重显著降低（p = 0.02，平均差异：0.75千克）。在身体成分或细胞健康方面未发现其他差异。30天内补充MTC对血压没有影响。尽管抗氧化剂和褪黑素具有潜在益处，但我们发现，服用MTC 30天的参与者在睡眠时间或质量、细胞健康或血压方面没有改善，不过胶囊组的体重有所下降。这些结果与之前关于MTC与睡眠和血压的研究数据相矛盾，因此有必要进一步研究。
