Why
The Deep Sleep Stack brings together three powerful, research-backed ingredients to optimise sleep quality, reduce anxiety, and support full-system recovery: Revival, Apigenin, and Theanine. Unlike harsh sedatives, these compounds work synergistically to improve NREM sleep, balance stress hormones, and enhance mood — without next-day grogginess. Hydrapharm’s Revival is a flagship sleep-enhancing and wellbeing supplement, with novel ingredients like Safranal, Emoxypine, and 2-Bromomelatonin — targeting sleep latency, sleep depth, and anxiety simultaneously. Apigenin, a natural flavonoid praised by neuroscientists like Andrew Huberman, supports GABA activity while helping regulate cortisol and testosterone balance. Theanine rounds out the stack, offering day and night versatility for reducing mental stress and promoting alpha-brainwave relaxation. Together, these three compounds promote high-quality, restorative sleep — the kind of sleep that enhances cognition, immunity, body composition, and recovery.
When
Take all three products 30–60 minutes before bedtime for best results. For sensitive users or first-timers, start with one capsule of each and increase if needed. Theanine can also be used in the daytime to manage stress or enhance focus.
Who
This stack is ideal for athletes, busy professionals, and sleep-deprived individuals looking to break free from grogginess, insomnia, and anxiety — especially those who want to avoid pharmaceutical sedatives. It’s particularly effective for wired but tired users who struggle to quiet their minds at night, as well as anyone looking to lower cortisol, balance mood, and improve hormonal recovery during sleep.
