Cortisol

Adrenal glands release hydrocortisone (cortisol) and other hormones; known as adrenal steroids. These steroids are critical for life and the key to physical and emotional. stress response. Unlike other hormones, adrenal steroids generally don't diminish with age.

Both adrenal and gonad steroids are derived from the basic cholesterol molecule. Through biosynthetic pathways, cholesterol. Is transformed into different steroid hormone molecules before becoming estrogen, progesterone or testosterone.

Among its functions, cortisol rouses bodily activities, on awakening: It influences protein, carbohydrate and fat metabolism; helps regulate blood pressure; and improves the integrity of blood vessels. Cortisol is also vital for immune function and helping mobilize against inflammation.

Plus, it fights bacterial and viral infections. Escalated levels of cortisol can actually suppress immune function. Called the "stress hormone," cortisol floods your body when emotional upheavals or emergencies arise.

Afterward, the brain stops cortisol production to normalize levels. If you're under chronic pressure and stress, escalated cortisol levels may saturate your body. Over time, these elevated cortisol levels lead to fat accumulation. Blood sugar problems, fatigue, bone loss and immune system impairment.

Chronic stress (physical or emotional) can also exhaust the adrenal glands, resulting in subnormal cortisol production--an insidious cycle that can cause premature aging of tissues arid total body burnout.

Taking adrenal steroids, such as pregnenolone or androstenedione, may significantly influence the levels of their end products: testosterone, estrogen and progesterone. Rejuvenate monitors levels of both the administered hormone and its end products.
