Rhodiola Rosea (siberian) Extract - Side Effects, Root, Herb - Dosage
Rhodiola Rosea is similar to other plants such as Siberian and Panax ginseng. Rhodiola produces favorable changes in a variety of diverse areas of physiological function including neurotransmitters, cardiovascular assistance, and the central nervous system.
Early Rhodiola extracts were standardized only with reference to the compound, salidroside. Since the 1990s, the standard for true Rhodiola rosea extracts requires at least 0.8 percent salidroside and 0.8 percent rosavins. Products that are only standardized for salidroside content may be adulterated with other Rhodiola species such as Tibetan or Indian Rhodiola. According the the scientific literature, these products do not have the same beneficial effects as Rhodiola Rosea.
In addition to enhancing the positive side effects of endurance and stamina, there have been claims that rhodiola influences thoughts associated with sex, however, this author at the time of this writing, has not had the opportunity to experiment with it.
It appears that Rhodiola Rosea intake for a day or two can improve endurance exercise capacity but long term use does not appear to make much of a difference. Practically speaking, it may make sense to take breaks from use.

Rhodiola Extends Fruit Fly Life Span
A report published online ahead of print in the journal Rejuvenation Research revealed the finding of researchers the University of California, Irvine that supplementing the diet of fruit flies with the herb Rhodiola rosea extended life span by 10 percent.
Professor of pharmaceutical sciences, Mahtab Jafari and associates, gave adult fruit flies varying doses one of three Chinese herbs (Lu Duo Wei, Bu Zhong Yi Qi Tang and San Zhi Pian) or rhodiola mixed in yeast paste. The flies received the herbs every other day for the duration of their lives. A control group received an unsupplemented diet.
While the other three herbs did not affect the flies life span, rhodiola increased it by an average of 10 percent, equivalent to 3.5 days in males and 3.2 days in females. The authors noted that correcting for a possible dietary restriction effect still did not eliminate the difference between supplemented and control flies. Nor, does the effect of Rhodiola depend on dietary manipulation which strongly suggests that is not a mere dietary restriction mimetic. (Editors note: Fasting or calorie restriction has been show to extend lifespan.)
Rhodiola, an herb that grows in high altitude Arctic regions of Europe and Asia, is believed to have antioxidant properties, and has been used by many individuals to support positive moods, energy levels, and stress response. Dr. Jafari is currently evaluating Rhodiolas' molecular mechanism by measuring its positive side effects on fruit flies energy metabolism, oxidative stress and antioxidant defenses and is initiating studies with Rhodiola in mice.
Although this study does not present clinical evidence that Rhodiola can extend human life, the finding that it does extend the lifespan of a model organism makes this herb a promising candidate for further anti-aging research. Dr. Jafari commented, "Our results reveal that Rhodiola is worthy of continued study and we are now investigating why this herb may work to increase lifespan."
