Scientific Information (Did You Know?)
A. Clinical studies of Guarana in energy boostingFunction 1: Improves Performance
Guarana (Paullinia cupana)
Guarana acts as the performance enhancer and memory improver. Studies on human have reported the function of guarana in secondary memory performance, cognitive and mood effect.
There was a first study on human to systematically assess acute, dose-related behavioural effects of the extract of guarana plant. Guarana has improved secondary memory performance and increased alert and content mood ratings1.
A double-blind, counterbalanced, placebo-controlled study was carried out to observe the cognitive and mood effects to separate doses of guarana, Panax ginseng and their combination. The study was assessed in 28 healthy young (aged 18-24) participants. The combination of guarana and Panax ginseng has enhanced the speed of memory task performance2.Function 2: Lipid Metabolism
Guarana (Paullinia cupana)
Guarana able to assist lipid metabolism. The recent study Guarana has positive effects on lipid metabolism which mainly related to low density lipoprotein (LDL) levels in body weight loss, increases in basal energy expenditure, lower prevalence of hypertension and metabolic syndrome.
Scientific study 1
The recent study performed by Universidade Federal de Santa Maria in Brazil had suggested and proved that Guarana has positive effects on lipid metabolism which mainly related to low density lipoprotein (LDL) levels in body weight loss, increases in basal energy expenditure, lower prevalence of hypertension and metabolic syndrome. In vivo results showed that guarana intake could reduce the diene levels in serum from elderly subject. The effects of guarana on LDL and serum oxidation are probably associated with some bioactive compounds (catechins and xantines), which may act to prevent atherogenesis through a combination of effects. This positive effect of guarana could be confirmed by in vitro results which showed an increased resistance to LDL oxidation. Furthermore, studies suggested that guarana exhibits a cardioprotective effect by inhibiting platelet aggregation3.
Scientific study 2
An animal study was also conducted to observe the effect of guarana extract and its component other than caffeine, on lipid metabolism of rats. Two different doses of whole extract or decaffeinated extract was adopted to see the effect of other components of guarana. The body weight, food and water intake, muscle fat content, oleate incorporation, glycogen content, and carnitine palmitoyltransferase I (CPT I) activity and mRNA expression, along with plasma lactate concentration were assessed. The result showed that muscle oleate incorporation was decreased in rats receiving decaffeinated guarana in relation to whole extract. Whole extract supplementation but not decaffeinated induced reduced plasma lactate concentration in trained rats. Whole extract (G1) showed higher muscle glycogen content compared with all other groups. The changes in lipid metabolism of supplemented rats were reported to associate with the methylxanthine content of guarana and it was terminated by decaffeination4.References

B. Clinical Studies of Panax ginseng in Energy BoostingFunction 1: Endurance
Studies have suggested there might be benefits of using Panax ginseng to improve the exercise performance in male subjects.
The ergogenic effect of Panax ginseng was evaluated by conducting a study to observe the effects of Panax ginseng extract on lipid peroxidation and scavenger enzymes induced by an acute exhaustive exercise in sedentary humans. Ingestion of 2g of Panax ginseng extract, 3 times a day for 8 weeks has prolonged the exercise duration of seven healthy male subjects until exhaustion. These findings support scientific claims that ginseng has ergogenic properties in simplifying recovery from exhaustive exercise1.Function 2: Anti-Hyperglycemic & Anti-Obese
Panax ginseng has the ability to improve the blood glucose and reduce plasma cholesterol. The anti-hyperglycemic and anti-obese effect was portrait through an animal study with obese diabetic mice which has been treated with Panax ginseng extract.
Panax ginseng was evaluated for its anti-hyperglycemic and anti-obese effects with obese diabetic mice. It was proved that Panax ginseng able to improve blood glucose and reduce plasma cholesterol. The improvement in blood glucose levels in the extract-treated mice was associated with a significant reduction in serum insulin levels in fed and fasting mice. In addition, the extract-treated mice lost a significant amount of weight, associated with a significant reduction in food intake and a very significant increase in energy expenditure and body temperature. Treatment with the extract also significantly reduced plasma cholesterol levels in mice. Additional studies demonstrated that ginsenoside plays a significant role in antihyperglycemic action2.Function 3: Reduce blood glucose
Panax ginseng is commonly used to treat diabetes since ancient times in traditional Chinese medicine.
A double blind placebo-controlled study was conducted with 30 healthy young adults using Panax ginseng G115. A single dose of 200mg G115 and 400mg G115 was used in this study both the doses led to significant reductions in blood glucose levels3.Function 4: Erectile Dysfunction
Panax ginseng may improve libido and able to maintain erection.
Panax ginseng has been used as a supportive herb for male potency. 1800mg/day of Panax ginseng extract was used for three months in a double-blind trial, and it resulted in the improvement of libido and the ability to maintain an erection in men with erectile dysfunction4.
It was also proved in another study in which 900mg of Panax ginseng was given for 3 times a day for 8 weeks5.Function 5: Immune function
Panax ginseng has a long history of use in herbal medicines for curbing and treating immune system related complications.
A double-blind study of healthy people found that taking 100 mg of a standardized extract of Asian ginseng twice per day improved immune functions6.Function 6: Male Infertility
A study found that men who took Panax ginseng had an improvement in sperm count, sperm motility, plasma total and free testosterone.
A preliminary study with 66 patients was conducted where 4 grams of Panax ginseng extract per day was taken for three months and it has showed an increase in spermatozoa number/ml and progressive oscillating motility, an increase in plasma total and free testosterone7.References
