AdreCor supports adrenal function and the synthesis of the adrenal neurotransmitters, epinephrine and norepinephrine , with a combination of amino acids, vitamins, and other nutrients. This formula is rich in B-vitamins that are important to the production of the adrenal hormones required to combat stress and fatigue. AdreCor contains an extract of the adaptogen, Rhodiola rosea , a source of biologically-active rosavins. NeuroScience's Rhodiola is standardized to contain 16% rosavins, which have been found to decrease the effects of stress and fatigue. N-acetyl-tyrosine and L-histidine are included to support the catecholamines and histamine, respectively.
