Stress Guard improves physical and mental fatigue in chronically stressed individuals. Higher and more prolonged levels of circulating cortisol (like those associated with chronic stress) have been shown to have negative effects, such as impaired cognitive performance, blood sugar imbalances, sleep disruption, lowered immune function, and increased abdominal fat. Longevity's Stress Guard contains phosphatidylserine and standardized extracts of one cortisol-lowering herb: Passiflora Incarnata to protect the body against the damaging effects of chronic stress and elevated cortisol.
