Desert plant extract containing echinacoside and acteoside that support testosterone via LH stimulation, enhance neurogenesis via BDNF upregulation, and improve gut microbiome composition. Traditional use as 'desert ginseng' for vitality and cognition.
Rhodiola's key bioactives are rosavin (unique to R. rosea), salidroside, and tyrosol. It modulates the HPA axis stress response by inhibiting cortisol release and stress-activated protein kinases (SAPKs/JNK). Salidroside activates AMPK, enhances mitochondrial biogenesis via PGC-1alpha, and stimulates glucose uptake. Rhodiola inhibits monoamine oxidase A and B (MAO-A, MAO-B), increasing synaptic serotonin, dopamine, and norepinephrine levels. It also stimulates Nrf2 antioxidant defense, increases erythropoietin (EPO) production, and enhances beta-endorphin levels during exercise.
