3.2 Anti-depression
Rosavins enhances the transport of serotonin precursors, tryptophan and 5-hydroxytryptophan into the brain. Unbalanced serotonin has been linked to various abnormal mental states such as clinical depression. Rosavins has been used by Russian scientists alone or in combination with anti-depressants to boost one’s mental state. In one experiment to 128 patients who take Rosavins, 65% of them more or less reduce or remove depression effectively.

Rosavins t has been shown to moderate stress-induced damage and dysfunction in cardiovascular tissues. Treatment with it prevents the decrease in cardiac contractile force secondary to environmental stress in the form of acute cooling and contributes to stable contractility. Pretreatment with Rhodiola Rosea extract appears to create a beneficial adaptive response in this type of stress.
