Adaptogens have long been associated with increasing energy, enhancing stamina, and reducing fatigue. They encourage physical work capacity and mental performance. Often referred to as tonics, they have far reaching effects on overall physiological health, supporting immune, cardiovascular, and endocrine functions. At the same time, they help the body to adapt to and cope with stress, primarily by supporting the hypothalamic-pituitary-adrenal (HPA) axis. Panax ginseng promotes endurance and stamina, while also promoting cognitive, cardiovascular and immune function. Ashwagandha is recognized for encouraging resistance to environmental stress and supporting immune function and cognitive function. Eleuthero and rhodiola are traditionally associated with rejuvenating effects and the ability to promote endurance.* Energy Xtra offers a blend of key adaptogenic herbs for enhancing mental and physical work capacity and stamina.*
