Ironman® Competitor Eric Harr Reveals His Performance Secret
World Class Triathlete Depends on SIBERGIN® for Physical, Mental Energy
As a professional triathlete and journalist, I experience stress on a daily basis – from endurance training to the mental exhaustion associated with my media work,” states Harr. “SIBERGIN® has been a key part of my nutritional regime for many years. It has helped me adapt physically and mentally to the stress in my life.” As an adpatogen, that is exactly what Siberian ginseng (or technically, eleuthero) – the star herb in SIBERGIN® – is renowned for. Adaptogens are a class of herbs that help the body adapt to all kinds of stress. In order to qualify as an adaptogen, an herb has to meet three key qualifications. First, the herb must produce a non-specific stress response in an organism. That means that instead of acting on a specific pathway, adaptogens simply increase a person’s overall resistance to stress.
Second, the herb must have a normalizing influence on physiology, in whatever direction is needed to maintain normal health. And third, the herb must be incapable of influencing normal body functions more than required to gain non-specific resistance. In other words, it has a safe balancing activity.1 Very few herbs qualify as true adaptogens. But eleuthero is one of them.
One of the world’s most researched herbs, eleuthero is the subject of dozens of studies, most of which were performed in the Soviet Union, where the herb naturally grows. The herb is of great interest to athletes like Harr, because it has been shown to enhance human performance under stressful conditions. A Japanese study, for example, tested the effects of eleuthero on participants’ total work output while riding a stationary bike. The researchers found that subjects who took eleuthero increased total work output by 23.3 percent, compared to a rise of only 7.5 percent for placebo.2
