Oral Nutritional Dietary Supplement Containing GABA and Asparagus Powder Improves Sleep

This paper focuses on the effects of two food materials, γ-aminobutyric acid (GABA) produced by natural fermentation and asparagus powder, on the improvement of sleep-in humans. The trial totaled 54 people, divided into three groups: intervention group A (active ingredient GABA 120mg, asparagus powder 1500mg), intervention group B (active ingredient GABA 120mg) and control group (without active ingredient) to carry out the sleep test, and the sleep effect was detected by Pittsburgh Sleep Quality Index (PSQI) and Huawei Sports Bracelet, respectively. The test results show: 1) From the subjective sleep score (PSQI sleep score): sleep quality improvement level intervention group A (28%) > intervention group B (26%) > control group (19%); the effective proportion of sleep aid people in intervention group A (83%)>Intervention Group B (75%)>Control Group (71%);2) The Huawei Sports Sleep Bracelet test showed that the deep sleep continuity of intervention group A improved by 7% after taking the product for one week, and 67% of the subjects improved the deep sleep continuity to varying degrees after taking the product for one week. Significantly higher than intervention group B and control group. Further analysis found that GABA and asparagus powder had a better effect on people with a deep sleep score of ≤70 points. Intervention group A underwent intervention for 1 week, and its total sleep score improved significantly, and there was a significant difference. This result indicates that nutritional dietary supplements can be helpful in improving overall sleep quality. Summary: GABA can help people fall asleep quickly, asparagus powder can induce deep sleep, and their simultaneous intake are complementary. The results of this study show that taking a nutritional dietary supplement of 120 mg of GABA and 1500 mg of asparagus powder every day can significantly improve the quality of deep sleep. Since GABA and asparagus powder are both raw materials in food and have been ingested for a long time, taking nutritional dietary supplements containing both of their ingredients is considered safe and suitable for daily intake, which can effectively improve the quality of deep sleep, thereby improving Overall level of sleep.
