JostArriba for cortisol balance, stress resilience
Lower cortisol. Ease stress. Feel like yourself again.
Chronic stress keeps cortisol high—a cycle that eventually depletes your mental and physical reserves.
Formulated with potent adaptogens like ashwagandha and reishi, and calming amino acid L-theanine from green tea, JostArriba is designed to lower serum cortisol, soothe your response to stress, and reclaim your natural state of balance.
Validated by science. Crafted for pleasure.
Clinically shown to lower cortisol
Ashwagandha is one of the most researched adaptogens for cortisol regulation. In double-blind, placebo-controlled trials, it has been shown to reduce cortisol by up to 30%, lower perceived stress scores, improve sleep quality, and support physical and cognitive endurance.
Namaste from green tea
JostArriba contains L-theanine, the amino acid found in green tea, promotes alpha brain waves — your brain's natural calm-focus state — shown in clinical trials to reduce anxiety and lower stress biomarkers.
Reishi — ancient calm, modern science
Reishi is a natural adaptogen used for centuries to calm the nervous system. Research shows it inhibits cortisol conversion and helps modulate the body's stress response at a hormonal level.
