Our body's two adrenal glands, which are triangle-shaped and about the size of a walnut, sit atop our kidneys. They are the glands that respond to STRESS.

The adrenals produce over 50 hormones, which are concentrated into about 10 major hormones that circulate through our system. Cortisol and aldosterone are two you may have heard of.

Fatigue comes about from not only social or emotional problems, but physical -- pollutants, poor foods, poor digestion, blood sugar regularities, chronic illnesses.

The hormones secreted by your adrenals influence all of the major physiological processes in your body.

They closely affect the utilization of carbs and fats, the conversion of fats and proteins into energy, the distribution of stored fat (especially around your waist and at the sides of your face), normal blood sugar regulation, and proper cardiovascular and gastrointestinal function.
