Peptiva + Sleep Support positions itself as a comprehensive solution for stress, mood, and sleep, leveraging popular ingredients like Melatonin, Valerian, GABA, and a proprietary probiotic blend. While the inclusion of PharmaGABA is a positive, as it's a well-regarded, bioavailable form of GABA, the dosages of other key ingredients are concerning. The Valerian extract is exceptionally low at 50mg, far below the clinically effective doses typically ranging from 300mg to 600mg for sleep and anxiety. The Melatonin dose of 0.75mg is also quite low; while some individuals respond to micro-doses, many find 1-3mg more effective for sleep initiation. The "Proprietary Probiotic Matrix" lacks transparency, as specific strains and CFU counts are not disclosed, making it impossible to assess its efficacy for gut-brain axis benefits related to mood or sleep. Furthermore, the product claims "Anti-Aging" benefits, which are not directly supported by the listed ingredients in any substantial way. At $1.66 per serving, this product is significantly overpriced given the inadequate dosages of its primary active ingredients and the undisclosed nature of its probiotic blend, especially when compared to alternatives offering higher potencies at a fraction of the cost. Online reviews, while numerous (4584), would need to be critically evaluated for their sentiment, as the low dosing might lead to mixed results for consumers expecting significant effects.
