The adrenal glands produce hormones that underlie the body’s mechanisms for coping with physical and mental stress. Overtraining in athletics, chronic anxiety, worry, nervous tension and other factors associated with excessive cortisol release are linked to adrenal exhaustion and fatigue. Over-reliance on caffeine and other stimulants also taxes the adrenals. Jarrow Formulas Adrenal Optimizer combines important nutrients and nutraceuticals that support adrenal health. Vitamin C, DMAE and pantothenic acid participate in the synthesis and release of adrenal hormones. Adrenal Optimizer works best when combined with adequate rest and sound nutrition.
