Rhodiola rosea is an adaptogenic herb that may significantly increase serotonin activity. Rhodiola may also increase the activity of two other mood-related neurotransmitters - dopamine (DA) and norepinephrine (NE) - by inhibiting the activity of COMT, an enzyme that breaks DA and NE.1 The effects of Rhodiola may be felt quickly, within a few days after starting supplementation. Rhodiola users report increased energy and motivation, reduced anxiety, and elevated feelings of confidence and optimism.
Before becoming known in the United States, Rhodiola was extensively studied by Russian scientists and was used for decades in the former Soviet Union as an energy-enhancer.
Numerous double-blind, placebo-controlled clinical trials show that Rhodiola can increase general wellbeing2, reduce mental fatigue2,3, and improve learning and memory4.
Each capsule of AMORYN contains 90mg of Rhodiola extract standardized to contain at least 4% rosavins. Standardizing the Rhodiola extract in AMORYN to this high concentration of rosavins, the active constituent, makes it consistently more potent than other Rhodiola supplements containing only 1-2% rosavins. A daily dose of AMORYN provides the amount of Rhodiola extract shown to be both effective and safe in clinical trials.
