Panax Ginseng is a slow-growing perennial plant native to North America and eastern Asia. It is the most well-studied kind of Ginseng. Acute supplementation may provide a subtle increase to focus, according to multiple peer-reviewed, double-blind, placebo-controlled studies on humans:
Panax ginseng (G115) improves aspects of working memory performance and subjective ratings of calmness in healthy young adults. In 2010, this study found that Ginseng "improved calmness and improved mental arithmetic". Participants with the best results used 400 mg of 4% ginsenoside extract (16 mg ginsenoside) daily. Supplementation was effective on the first day and remained effective on the eighth day.
Effects of Panax ginseng, consumed with and without glucose, on blood glucose levels and cognitive performance during sustained 'mentally demanding' tasks. In 2006, this study found that Ginseng "can enhance cognitive performance". Participants used 200 mg of 4% ginsenoside extract (8 mg ginsenoside). Supplementation was effective on the first day.
Single doses of Panax ginseng (G115) reduce blood glucose levels and improve cognitive performance during sustained mental activity. In 2005, this study found that Ginseng "can improve performance and subjective feelings of mental fatigue during sustained mental activity". Participants with the best results used 200 mg of 4% ginsenoside extract (8 mg ginsenoside). Supplementation was effective on the first day.
- Effects of Panax ginseng on quality of life. In 2002, this study found that Ginseng "improves aspects of mental health and social functioning". Participants used 200 mg daily. Supplementation was effective at one month and less effective at two months.
Although effective as a standalone nootropic, Ginseng may be more effective when combined with Caffeine, according to this peer-reviewed, double-blind, placebo-controlled study on humans:
- Effects of acute supplementation of caffeine and Panax ginseng on endurance running performance in a hot and humid environment. In 2011, this study found that "combined and acute supplementation of caffeine and PG in the said doses improved the endurance running performance of the heat-adapted male recreational runners". Participants used 200 mg of Ginseng. Supplementation was effective on the first day.
Traditionally, Ginseng supplements have been prepared from the root of the plant, but the leaves and stem of Ginseng may be a better choice. The leaves and stem have higher concentrations of the bioactive ginsenoside. And evidence suggests that the root may be no more effective, while leaves and stem may be more environmentally sustainable.
Based on these and other studies, Thrivous developed Surge, the acute nootropic for occasional use when you need extra energy and focus. A single serving (one capsule) of Surge contains 170 mg of a 7% ginsenoside extract of Ginseng, or 12 mg of ginsenoside. Surge also contains Caffeine to complement the Ginseng. Accordingly, supplementation with Surge may provide extra energy and focus when you need it. Talk to your doctor about using Surge today!
