Following increased commodity prices and legislation from the Government, the Boost bar in the United Kingdom was shrunk from 60g down to 48.5g in 2013. In 2014, the Boost Duo version also shrank by 10g to 68g. The wrapper was notably updated to reflect the new Reference Intakes and use of Palm and Shea fat in the product. Doping is a very serious offence, and in athletics the price is high if found guilty and rightly so, but athletes do need food supplements, from time to time, especially iron, most doctors now have a list of banned substances and will know what to prescribe. Bonadiman BdSR, et al. (2017). Guarana ( Paullinia cupana): Cytoprotective effects on age-related eye dysfunction. These very weak electrical currents cause the muscles to move and transmit impulses to the nerve pathways. In this way, all information within the body is passed on via the nerve pathways. The nerve tract 'transmits' as long as there is electrical voltage. Potassium has the task of relieving tension in the nerve cells and producing a normal electrical charge. Recent studies seem to show a rather positive interaction with ginseng: The mental performance can be increased if ginseng is also taken with guarana. In studies, it was determined that all subjects who received ginseng and guarana together had increased attention and better memory as compared to the comparison groups.

There are no known side effects of a moderate consumption of guarana. The risks that arise from the consumption of guarana lie in particular in an overdose. However, the symptoms of an overdose are primarily indicated by the caffeine that is contained in the guarana seeds. Bortolin RC, et al. (2019). Guarana supplementation attenuated obesity, insulin resistance, and adipokines dysregulation induced by a standardized human Western diet via brown adipose tissue activation. Another important factor to consider is the source of the guarana. Look for supplements made from guarana that has been sustainably harvested and ethically sourced. This ensures that the product is not only good for you, but also good for the environment and the people who harvest it. The catechin and epicatechin are particularly noteworthy here: The phytochemicals are primarily known for their antioxidant effects, which far exceed the antioxidative potential of vitamin C or vitamin E. Guarana effect In addition to adolescents, athletes in the amateur and semi-professional sector form another target group of products that contain guarana to improve performance. However, no studies on guarana and a possible overdose are known in this area. The recommended dose is often based on the experience with caffeine from other sources. Guarana side effects
Taste – The taste is tough to manage and pretty bitter. However, you can blend it in favorably with coffee, creamer, and agave syrup. More recently, studies show that adding guarana to your routine could come with a pretty long list of benefits. It may help optimize memory, fight fatigue, improve heart health and do even more to keep you feeling your best. But there also are some guarana side effects to be aware of. We highly recommend the Awakening Natural Energy & Focus Nootropic Supplement by Oxygen Nutrition. It is a great product that can help you stay focused and energized throughout the day.Scientists believe that the potential anti-cancer properties of guarana stem from its content of xanthines, which are compounds that are similar to caffeine and theobromine. Another problem with the guarana studies is that the test subjects did not consume pure guarana products. For example, one study explicitly dealt with the effect of energy drinks on the human organism. The data from the emergency rooms of various hospitals were primarily used for this. It was noticed that there were irregular referrals in which the symptoms after consuming guarana in the form of energy drinks resembled an overdose of caffeine. Additionally, guarana is often used as an additive for unhealthy beverages. These include guarana energy drinks or guarana alcohol products. Drinks that this are often pumped full of unhealthy added sugar and extra ingredients. These products essentially negate any health benefits of guarana. They can actually do more harm than good when it comes to your health. Guarana vs. Other Energy Drinks/Supplements What’s more, a study that included 33 people with anxiety found that supplementing with 1,000 mg of gotu kola extract per day for 2 months helped improve attention and reduce their anxiety and mental fatigue rate, compared with their baseline ( 41). Summary Guarana seeds are best known for their very high caffeine content — double the caffeine found in coffee beans.
Gotu kola has been used in traditional medicine systems to help improve brain function, as well as studied for its beneficial effects on alertness and mood. Exposing planarians to guarana seed extract, caffeine and glucose together resulted in augmented planarian motility after both short and long-term stimulation, but only with our low concentration combination ( Fig 7). However, since our low concentration of guarana seed extract coupled with our low concentration of glucose also offered a sustained significant stimulation after the one-hour incubation, we cannot conclude that caffeine had an additional effect in this situation. On the other hand, the triple combination was the only one tested that resulted an increased pLmV after only two minutes of stimulant exposure. Significantly, these data provide evidence that low concentrations of guarana, caffeine and glucose in combination are sufficient to provide a short-term stimulus. Guarana is usually taken as a capsule or as a tablet with some fluids. Guarana powder, on the other hand, should be mixed with some fluids and then drunk. Which fluids they are depends on the composition of the powders, tablets and capsules. If vitamins and minerals are added or if it is a fat burner, a booster for bodybuilders or similar, various interactions must be taken into account. The manufacturer's information also helps here. Guarana: Natural product and vegan Guarana in Combination with Glucose and Caffeine Provides a Short-Term Stimulus at Low Concentrations Gleason JL, Sundaram R, Mitro SD, Hinkle SN, Gilman SE, Zhang C, Newman RB, Hunt KJ, Skupski DW, Grobman WA, Nageotte M, Robinson M, Kannan K, Grantz KL. Association of maternal caffeine consumption during pregnancy with child growth. JAMA Netw Open. 2022;5(10):e2239609. doi:10.1001/jamanetworkopen.2022.39609In addition to a hefty serving of guarana-derived caffeine, energy drinks are loaded with sugar. One brand, for example, contains about 27 grams of added sugar per can. For context, The American Heart Association recommends adults limit added sugar to no more than 25 to 36 grams in an entire day.
Research shows that sage ( Salvia) may have impressive cognitive-enhancing effects in adults. It’s high in many potent plant compounds, including luteolin, rosmarinic acid, camphor, quercetin, and apigenin, which give it its impressive medicinal properties ( 6).

One of the main points she drew on was that she was not in a financial position to appeal her ban to the International Appeals Board, to clear her name. Another point she highlighted was that if she as an athlete had to get all her food supplements tested, it would cost her in the region of ?600 to test a supplement worth ?30. The mental performance that is supposed to be possible under the influence of guarana is generally attributed to the caffeine it contains. However, scientists are not sure about the performance-enhancing effects of guarana powder, which is the reason for it. Two older studies dealing with the acute and long-term use of guarana did not come to a clear result: Guarana had no increasing effect on the mental performance. Because guarana is said to help reduce the body's fat percentage, it is particularly popular with bodybuilders and other strength athletes. The positive effect of caffeine on fat burning was demonstrated in a Korean study with ten participants. Although the study did not deal with guarana in particular, but with the effects of caffeine in general, the results can provide information about the possible effects of guarana seeds.
