Thus, I performed multiple searches trying to find other research articles that may lend support to using WM as a post-workout supplement. Despite numerous searches, the only study that somewhat provided evidence for the use of WM was a research experiment conducted by Piehl Aulin et al 4.
According to many WM manufacturers and distributers, this study serves as one of the primary proofs that WM is a superior glycogen replenishing supplement. In their study, Piehl Aulin et al. Each glycogen depleting workout lasted 2 hours and the different carbohydrate drinks were taken soon after completing each workout. It was found that the HM carbohydrate led to significantly greater muscle glycogen content after 2 hours.
Since WM is considered a HM carbohydrate and carbohydrates like maltodextrin are of LM, product manufactures started to proclaim that WM was far superior at supporting anabolism tissue growth and replenishing glycogen stores. The study by Piehl Aulin et al. Second, the total muscle glycogen content between the HM and LM carbohydrates was only significant when measured at 2 hours.
When muscle samples were taken at 4 hours, there was no significant difference between the muscle glycogen content following the ingestion of the HM compared to the LM carbohydrate. Does this mean that waxy maize is a bad supplement? Of course not; it just means that there are better times of the day to take it than following a workout.
In fact, due to its lower GI, Sands et al. Thus, the body could partially preserve its own glycogen stores, while relying on this dietary glucose as a source of energy. In conclusion, waxy maize starch is not the best source of carbohydrates post workout. So in spite of hours of investigation, I just couldn't find any reason to use WMS.
Even speaking to a dozen or so people from the companies that sell it, couldn't provide me with one single study about this substance. Worse than simply not being able to justify claims about its rapidity, most of the available information suggests that WMS is a poor carbohydrate to use after training. We can hope that our product contains "faster" WMS, which will undoubtedly become the new claim, but even at best this is similar to dextrose and maltodextrin.
Considering that dextrose is the cheapest supplement in existence, this begs the question: what are we paying for? Sadly no. I'll consider it penance for having mentioned WMS in the past. Interestingly, even if I were the CEO of a competing company, it wouldn't impact the scientific literature or the unsupported claims.
This review isn't suggesting that WMS can't restore muscle glycogen, it simply shows that at best it is not superior to dextrose or maltodextrin. Of course we can't personally determine whether our gastric emptying is superior to other fast carbs - even taking blood sugar measurements is not sensitive enough to ascertain this.
To date, there are no comparison gastric emptying studies with WMS. Lastly, don't forget that this is an investigative literature review, not an opinion piece. No, just human. You're experiencing something called cognitive dissonance or true-believer syndrome, both of which are natural psychological phenomena.
In time, reason should prevail, but for now it's important enough to recognize that your judgment is being affected. Cognitive dissonance is an uncomfortable feeling caused by holding two contradictory ideas simultaneously. The "ideas" or "cognitions" in question may include attitudes and beliefs, and also the awareness of one's behavior. True-believer syndrome is a term coined by M. Lamar Keene in his book The Psychic Mafia.
Keene used the term to refer to people who continued to believe in a paranormal event or phenomenon even after it had been proven to have been staged. This literature review isn't about telling you what to do; it's about giving you the information with which to make an educated decision.
Whether or not you choose to risk your performance and money has no bearing on whether someone else may not want to take those risks.
It's ultimately your choice, and you deserve to have all of the information with which to make it.

Amylopectin Amylopectin is a highly branched polymer of glucose found in plants.
History Of Waxy Maize The exact history of waxy maize is unknown. Inverse association between the effect of carbohydrates on blood glucose and subsequent short-term food intake in young men. Am J Clin Nutr. Effect of starch structure on glucose and insulin responses in adults. Colonic fermentation of indigestible carbohydrates contributes to the second-meal effect. The effects of pre-exercise starch ingestion on endurance performance.
Int J Sports Med. Slowly digestible waxy maize starch prepared by octenyl succinic anhydride esterification and heat-moisture treatment: glycemic response and mechanism. The influence of starch structure on glycogen resynthesis and subsequent cycling performance.
Maltodextrin is a commonly used source of carbohydrates in many carbohydrate supplements today because it is very inexpensive. However much like Dextrose, it is a low-quality carbohydrate. Waxy Maize starch is a slow digesting carbohydrate, where Dextrose and Maltodextrin are fast digesting carbohydrates. With a glycemic index of 63, Waxy Maize absorbs slower, raising blood sugar levels more slowly and in the process reducing the chances of a spike then crash in energy versus Dextrose and Maltodextrin.
Generally considered to be a step up in performance carbohydrates from Dextrose and Maltodextrin. Waxy Maize is derived from natural cornstarch and is a food grade modified starch. Waxy Maize has a higher molecular weight and lower osmolarity rate when compared many other carbohydrates while containing no simple carbohydrates or monosaccharides. Waxy Maize will provide longer lasting energy when compared to Dextrose and Maltodextrin, which is beneficial in controlling spikes in insulin and providing sustained energy for endurance athletes, who need steady energy over longer periods.
Waxy Maize will run a little higher in price compared to Dextrose and Maltodextrin, but is a higher quality of carbohydrate. Karbolyn is a homopolysaccharide made from potato, rice, and corn. It is considered the highest quality sports carbohydrate supplement of the group for performance. Karbolyn is a complex carbohydrate, which provides up to two hours of sustained energy. But, unlike Waxy Maize, Karbolyn is processed to attain rapid absorption into the bloodstream and muscles.
Its glycemic index is 80—, which means Karbolyn passes through the stomach very quickly. Tags: None. Originally posted by aLegend View Post. Comment Post Cancel. Try 70g of Malto after a workout and the next day try 70g of Waxy Maize after a workout. IMO, you should feel the difference on how you feel afterwards. WMS all the way! My bw is pounds Shall I keep this for waxy? That sounds about right. Sometimes for breakfast, if I'm running late, I'll take 70g or so of Waxy Maize for my carbs.
I could never do that with Malto or Dextrose.
