We have talked about how cortisol hijacks your sleep. Now let us talk about the ingredient that actually does something about it.
Ashwagandha is not a trend — it is the most clinically validated adaptogen for cortisol reduction. The KSM-66 extract used in RestEase was shown in a gold-standard 60-day trial to reduce serum cortisol by nearly 28 percent. It works by regulating your HPA axis, the stress-response system that decides how much cortisol floods your bloodstream. When that system calms down in the evening, melatonin rises naturally. You fall asleep easier. You stay in deep sleep longer.
RestEase includes KSM-66 at the exact dose used in clinical research. No pixie-dusting. No guesswork.
