Beta-alanine Beta-alanine stands out as an ingredient that helps with muscle fatigue by increasing carnosine, a metabolite that helps to “buffer” acid production in the muscle. that caffeine taken before moderate-intensity cycling has a dose-response effect on reducing leg pain during exercise14. For example, 5mg caffeine/kg bodyweight given one hour prior to high-intensity cycling exercise significantly reduces leg muscle pain during the exercise15, and 5mg caffeine/kg bodyweight given after eccentric exercise may decrease pain during subsequent maximal eccentric contractions16. A recently published study found that the co-ingestion of caffeine (8mg/kg bodyweight) with carbohydrate (4g/kg bodyweight) after carbohydrate-depleting endurance exercise led to a significantly greater glycogen resynthesis (66%) than the ingestion of carbohydrate alone17. Hopefully, future studies will show that smaller doses of caffeine are effective, as well. O H2 N Source: Wikipedia OH As noted by Roger Harris, Ph.D., professor of Sports, Exercise and Health Sciences at the University of Chichester, and a world-renowned sports nutrition scientist, beta-alanine EAAs/BCAAs, Waxy Maize Starch and Antioxidants should not be taken or made commercially available as a free It is clear that both essential amino acids (EAAs, there are powder. In this form, beta-alanine is very quickly absorbed eight for adults) and branched-chain amino acids (BCAAs; and concentrated in the bloodstream, causing paraesthesia, a there are three; the EAAs include all BCAAs) play pivotal form of neuropathic pain. In addition, rapidly absorbed beta-alanine is quickly lost in the urine, if the blood concentration is high, limiting the amount retained The pace of introducing new energy products shows little signs of slacking. Mintel International’s GNPD in the muscle and available for the synrecords at least 16 U.S. products mentioning energy benefits launched in the relatively slow month of thesis of carnosine. August this year. A recent Mintel report values the U.S. retail energy drink market at $4.8 billion, with When formulating beta-alanine, Harris growth over 400% from 2003. “‘Energy’ is a buzzword used by companies wishing to send a simple mesindicates it is likely that beta-alanine will sage to consumers for a complex concept,” says Lynn Dornblaser, director, Custom Solutions Group with Mintel International. “Energy could refer to mental, stamina or other physical benefits, for example. It is react with aldehyde groups (such as something of which consumers wish they had more.” those in simple sugars) over time. Indeed, “Prepared Foods’ 2007 R&D Trends Survey: Functional Foods” reported that 63% of food Therefore, it is important to test the stabilmanufacturers said that “sustained energy release” was an important characteristic for an energy ity of beta-alanine in bar and drink prepaproduct to have; 49% said specialty ingredients that enhanced energy metabolism were; 47% said rations that may be formulated for a lonstimulants were important; and 44% said high amounts of quickly utilized energy sources, such as ger shelflife. Beta-alanine already has glucose, sucrose, maltodextrins and starches, were important in an energy product. Some of these latter been formulated into RTD preparations. ingredients provide desired sweetness, as well. Indeed, as the recently launched products show, there is Sweet Energy Survey Caffeine Caffeine is the most widely used, legal psychoactive agent worldwide. In doses of 4mg/kg, caffeine can increase mental alertness and improve logical reasoning, free recall and recognition memory tasks8. In addition to improving focus and alertness, caffeine can help increase time to exhaustion in endurance exercise bouts9,10, decrease ratings of perceived exertion during submaximal endurance exercise11,12 and improve physical performance during periods of sleep deprivation13. Caffeine may also play an important role in recovery, by helping reduce muscle pain and soreness. Research shows NS4 OCTOBER 2008 little consistency among energy products in regards to ingredients used or, more specifically, in attitudes towards carbohydrates and sweeteners. At one end of the spectrum, Sunbeam Bakers’ new Honey Grain Wheat Bread containing honey, highfructose corn syrup and starches from grain notes that it offers “a bountiful supply of complex carbohydrates; a source of energy.” On the other hand, Promax Nutrition’s new Promax 70 High Energy Snack Bars notes it does not contain high-fructose corn syrup. Ingredients that do appear on its legend to provide both energy and sweetness include corn syrup, lactose-containing whey, fructose and sugar. In contrast, Mintel’s GNPD reports that new Life Fitness Rapid Energy Berry Fruit Chewing Gum by Advanced Healthcare Distributors claims to “help boost energy fast.” Its main components are vitamin B12, along with natural fruit and berry extract and the sweeteners xylitol and maltitol syrup. The company also just introduced a Taurine & B Vitamins Energy Drink under the Blade Energy brand, with a sugar-free claim and sucralose and acesulfame potassium as sweeteners. Western Family’s Complete nutritional drink, with 24 essential vitamins and minerals, notes it contains “carbohydrates to provide energy,” and lists corn syrup, maltodextrin and sugar (sucrose) high on its ingredient statement. If such a survey of recent new products indicates anything, it is that there are no obvious ingredient choices when it comes to sweeteners and carbohydrates in products touting energy attributes. —Claudia D.
