For some people, giving up caffeine is probably a good idea. However, the general advice is not to give up caffeine immediately, but rather to take a phased approach. This ‘double strength’ Go Energy + Caffeine Gel is based on the same formula as the innovative SiS GO Isotonic Energy Gel, with the addition of 150mg caffeine; double the caffeine for performance, in one gel. According to DSST, alcohol causes a decrease in performance on their standardized tests, and caffeine causes a significant improvement. [153] When alcohol and caffeine are consumed jointly, the effects of the caffeine are changed, but the alcohol effects remain the same. [154] For example, consuming additional caffeine does not reduce the effect of alcohol. [154] However, the jitteriness and alertness given by caffeine is decreased when additional alcohol is consumed. [154] Alcohol consumption alone reduces both inhibitory and activational aspects of behavioral control. Caffeine antagonizes the activational aspect of behavioral control, but has no effect on the inhibitory behavioral control. [155] The Dietary Guidelines for Americans recommend avoidance of concomitant consumption of alcohol and caffeine, as taking them together may lead to increased alcohol consumption, with a higher risk of alcohol-associated injury. Citrus: Water, Maltodextrin (from Maize) (33%), Natural Flavouring, Gelling Agents (Gellan Gum, Xanthan Gum), Acidity Regulators (Citric Acid, Sodium Citrate), Caffeine (75mg), Preservatives (Sodium Benzoate, Potassium Sorbate), Sweeteners (Acesulfame K, Sucralose), Sodium Chloride, Antioxidant (Ascorbic Acid). Paraxanthine (84%): Increases lipolysis, leading to elevated glycerol and free fatty acid levels in blood plasma.

Decreased cancer risk. Drinking 2–4 cups of coffee per day may reduce liver cancer risk by up to 64% and colorectal cancer risk by up to 38% ( 41, 42, 43, 44, 45).GO Energy + Caffeine Gel can be consumed 30-minutes before intense exercise for mental preparation. A further one or two gels can be consumed towards the end of your endurance exercise period when you feel you need a physical boost or to improve alertness and concentration. Simply tear off the top of the sachet and squeeze the gel directly into your mouth. Most of these studies have looked at caffeine from coffee only. What are the short-term effects of consuming caffeine? Caffeine improves muscular strength and power, [66] and may enhance muscular endurance. [67] Caffeine also enhances performance on anaerobic tests. [68] Caffeine consumption before constant load exercise is associated with reduced perceived exertion. While this effect is not present during exercise-to-exhaustion exercise, performance is significantly enhanced. This is congruent with caffeine reducing perceived exertion, because exercise-to-exhaustion should end at the same point of fatigue. [69] Caffeine also improves power output and reduces time to completion in aerobic time trials, [70] an effect positively (but not exclusively) associated with longer duration exercise. [71] Specific populations Adults GO Energy + Caffeine Gel is an energy gel designed for high intensity competition that provides fast-absorbing and easily digestible carbohydrate along with caffeine. Combined, the two ingredients give you physical and mental focus when you need it.

Caffeine's biological half-life– the time required for the body to eliminate one-half of a dose– varies widely among individuals according to factors such as pregnancy, other drugs, liver enzyme function level (needed for caffeine metabolism) and age. In healthy adults, caffeine's half-life is between 3 and 7hours. [8] The half-life is decreased by 30-50% in adult male smokers, approximately doubled in women taking oral contraceptives, and prolonged in the last trimester of pregnancy. [126] In newborns the half-life can be 80hours or more, dropping very rapidly with age, possibly to less than the adult value by age 6 months. [126] The antidepressant fluvoxamine (Luvox) reduces the clearance of caffeine by more than 90%, and increases its elimination half-life more than tenfold; from 4.9hours to 56hours. [187] Caffeine in coffee and other caffeinated drinks can affect gastrointestinal motility and gastric acid secretion. [86] [87] [88] In postmenopausal women, high caffeine consumption can accelerate bone loss. [89] [90] An English neuroscientist on the faculty at University of California, Berkeley, Walker, author of Why We Sleep, is single-minded in his mission: to alert the world to an invisible public-health crisis, which is that we are not getting nearly enough sleep, the sleep we are getting is of poor quality, and a principal culprit in this crime against body and mind is caffeine. Caffeine itself might not be bad for you, but the sleep it’s stealing from you may have a price. According to Walker, research suggests that insufficient sleep may be a key factor in the development of Alzheimer’s disease, arteriosclerosis, stroke, heart failure, depression, anxiety, suicide and obesity. “The shorter you sleep,” he bluntly concludes, “the shorter your lifespan.” Our Energy + Caffeine (75mg) Energy Gel is based on the same formula as the innovative SiS GO Isotonic Energy Gel, with the addition of 75mg caffeine. Caffeine is one of the most researched stimulants in sports science and has been shown to increase alertness and concentration, which may benefit endurance and sprint based performance. USAGE: Endurance performance (over 90 minutes): Consumption of caffeine after abdominal surgery shortens the time to recovery of normal bowel function and shortens length of hospital stay. [48]

Decaffeinated" coffees do in fact contain caffeine in many cases– some commercially available decaffeinated coffee products contain considerable levels. One study found that decaffeinated coffee contained 10mg of caffeine per cup, compared to approximately 85mg of caffeine per cup for regular coffee. [208] Detection in body fluids It’s hard to imagine that the sort of political, cultural and intellectual ferment that bubbled up in the coffeehouses of both France and England in the 17th century would ever have developed in a tavern. The kind of magical thinking that alcohol sponsored in the medieval mind began to yield to a new spirit of rationalism and, a bit later, Enlightenment thinking. French historian Jules Michelet wrote: “Coffee, the sober drink, the mighty nourishment of the brain, which unlike other spirits, heightens purity and lucidity; coffee, which clears the clouds of the imagination and their gloomy weight; which illumines the reality of things suddenly with the flash of truth.” Around noon, my compulsiveness began to subside, and I felt ready for a change of scene. I had yanked a few plants out of the vegetable garden that were not pulling their weight, and decided to go to the garden centre to buy some replacements. It was during the drive that I realised the true reason I was heading to this particular garden centre: it had this Airstream trailer parked out front that served really good espresso.

[80] The American Congress of Obstetricians and Gynecologists (ACOG) concluded in 2010 that caffeine consumption is safe up to 200mg per day in pregnant women. [29] For women who breastfeed, are pregnant, or may become pregnant, Health Canada recommends a maximum daily caffeine intake of no more than 300mg, or a little over two 8oz (237mL) cups of coffee. [72] A 2017 systematic review on caffeine toxicology found evidence supporting that caffeine consumption up to 300mg/day for pregnant women is generally not associated with adverse reproductive or developmental effect. [73] Caffeine is metabolized in the liver by the cytochrome P450 oxidase enzyme system, in particular, by the CYP1A2 isozyme, into three dimethyl xanthines, [188] each of which has its own effects on the body:

Just like the Beta Fuel Energy Gel, our Nootropics Gel contains 40 grams of carbohydrate, with added nootropic substances that can enhance cognitive performance, giving you that mental lift you might need, especially at the latter phases of exercise. Death from caffeine ingestion appears to be rare, and most commonly caused by an intentional overdose of medications. [144] In 2016, 3702 caffeine-related exposures were reported to Poison Control Centers in the United States, of which 846 required treatment at a medical facility, and 16 had a major outcome; and several caffeine-related deaths are reported in case studies. [144] The LD 50 of caffeine in rats is 192 milligrams per kilogram, the fatal dose in humans is estimated to be 150–200 milligrams per kilogram (2.2lb) of body mass (75–100 cups of coffee for a 70kg (150lb) adult). [145] [146] There are cases where doses as low as 57 milligrams per kilogram have been fatal. [147] A number of fatalities have been caused by overdoses of readily available powdered caffeine supplements, for which the estimated lethal amount is less than a tablespoon. [148] The lethal dose is lower in individuals whose ability to metabolize caffeine is impaired due to genetics or chronic liver disease. [149] A death was reported in 2013 of a man with liver cirrhosis who overdosed on caffeinated mints. [150] [151] Interactions It may also increase blood adrenaline levels and increase brain activity of the neurotransmitters dopamine and norepinephrine ( 3).Designed especially for long, tough endurance events, our GO caffeine shots are easy to digest and carry with you.

[45] Evidence to support this practice is poor. [45] It appears that caffeine in low doses improves airway function in people with asthma, increasing forced expiratory volume (FEV1) by 5% to 18% for up to four hours. [46] Interestingly, consuming decaffeinated coffee was also linked to a 21% lower risk of diabetes. This indicates that other beneficial compounds in coffee can also protect against type 2 diabetes ( 36). Summary
