Vitadren is specially formulated to include the natural ingredients that regulate the circadian rhythm of adrenaline release to ameliorate stress-caused mental fatigue and restless sleep, enhance the immune system, and strengthen cognitive function.

Long-term stress is often the cause of adrenal fatigue; it can disrupt adrenal hormone cycle resulting in restless sleep, as well as declined cognitive ability and immune function.

Excessive stress stimulates constant epinephrine/norepinephrine and cortisol secretion and causes the body to stay alert even at times of resting. At sustained high levels, cortisol can gradually wear down the body as it slows down the healing, normal cell regeneration and production of biochemicals needed to make other vital hormones; impairs digestion, metabolism and mental function; and disrupts endocrine and immune function.

Overtime, acute stress will cause the depletion of adrenal hormone storage,
which subsequently leads to decreased level of serotonin and melatonin and other hormone imbalances, resulting in poor rest quality. The result is a vicious cycle.
