Gaia Herbs PRO Sleep Maintenance is a professional-grade, drug-free herbal sleep formula specifically designed for sleep maintenance — supporting the ability to stay asleep through the night and achieve restorative sleep architecture, rather than simply helping with sleep onset. It uses clinically studied botanicals that promote GABA activity, reduce cortisol-driven nighttime wakefulness, and support the nervous system's transition to and maintenance of deep sleep.Passionflower (Passiflora incarnata) contains chrysin and other flavonoids that increase GABA receptor activity — reducing neuronal excitability and the racing thoughts that cause nighttime wakefulness. Valerian Root provides valerenic acid that also modulates GABA receptors while reducing the activity of the HPA axis at night. Hops Strobile provides complementary sedative activity that potentiates valerian's effect. California Poppy provides gentle anxiolytic and sleep-prolonging activity. Skullcap supports nervous system calm. Non-GMO, gluten-free, vegan. Liquid Phyto-Caps® for superior absorption. Available at Beauty Riche with same-day shipping.
