This study describes the effect of bovine alpha-S1 casein tryptic hydrolysate (CTH) in a representative sample of day-time workers from the general population of Japan with the occurrence of insomnia during the preceding six months. To investigate this issue, 32 subjects, aged between 25 and 40 years, were examined for the sub- jective sleep quality using the Japanese Pittsburg Sleep Quality Index (PSQI-J). CTH significantly improves the PSQI total score of the treated subjects. It particularly…

A tryptic hydrolysate from bovine milk αs1-casein enhances pentobarbital-induced sleep in mice via the GABAA receptor

Melatonin-rich milk fortified with alpha s1 casein tryptic hydrolysate improves primary insomnia: a randomized placebo controlled trial

In subjects with primary insomnia consuming NightMilk produced small but significant improvements in insomnia symptoms, sleep efficiency, depth of sleep but did not increase TST, similar to other less well designed evaluations of non-pharmacological preparations.

The Effect of A Whey-Protein and Galacto-Oligosaccharides Based Product on Parameters of Sleep Quality, Stress, and Gut Microbiota in Apparently Healthy Adults with Moderate Sleep Disturbances: A Randomized Controlled Cross-Over Study

Although DP did not improve sleep quality in ITT and PP populations, it did in the modPP, and reduced salivary cortisol and stimulated Bifidobacterium, which possibly is important for sleep improvement.

A Double-Blind, Randomized, Placebo-Controlled Crossover Clinical Study of the Effects of Alpha-s1 Casein Hydrolysate on Sleep Disturbance

Overall perceived sleep profiles in sleep diaries were significantly improved during the ACH phase, represented by increased total sleep time and sleep efficiency (SE), as well as decreased sleep latency and wake after sleep onset (WASO).

Short-Term Anxiolytic and Pro-HypnoticActivity of a Tryptic Hydrolysate ofBovine Îs1-Casein in Patients withAnxiety Spectrum Disorders

The comparison of all rating scales mean scores reported at T0 versus T1 showed a statistically significant decrease, and the 64% of the sample reported an anxiolytic effect, and among the 64 patients with sleep disorders, the 51.5% reported a pro-hypnotic effect.

Health-related functional value of dairy proteins and peptides

Role of Lactium™ in Psychodermatology: The CERTAIN Trial# on Patients with Acne Vulgaris

In patients with moderate-to-severe acne vulgaris, Lactium™ was found to be both safe and well-tolerated, and more effective than standard care alone in reducing acne severity through stress reduction.

Food protein-derived anxiolytic peptides: their potential role in anxiety management.

The data is reviewed of the structure/activity relationship, physiological effects displayed in in vitro and in vivo assays, bioavailability, and safety profiles of anxiolytic peptides, suggesting that these molecules may exert their effects at different levels.

Exploring the Effect of Lactium™ and Zizyphus Complex on Sleep Quality: A Double-Blind, Randomized Placebo-Controlled Trial

It currently cannot be concluded that administration of LZComplex3 for 2 weeks improves sleep quality, however, a marked placebo response (despite placebo run-in) and/or short duration of treatment may have masked a potential beneficial effect on sleep quality.

Association between Adherence to the Japanese Food Guide Spinning Top and Sleep Quality in College Students

A well-balanced diet may be associated with good sleep quality in Japanese college students because of the association between adherence to the Japanese Food Guide Spinning Top score.

Characterization of α‐casozepine, a tryptic peptide from bovine αs1‐casein with benzodiazepine‐like activity

Evidence of a novel anxiolytic activity in a tryptic hydrolysate of bovine αs1‐casein is shown, which could be related to the carboxy‐terminal sequence of the polypeptide diazepam binding inhibitor, an endogenous ligand of the central GABAA and peripheral‐type benzodiazepine receptors.
