22 INSIDER September/October 2018 "It's kind of funny how the most effective ingredients are often the worst-tasting ones," Tuell said. "However, we worked with an excellent team of chemists to create the most delicious fl avor profi le possible, while still maintaining a light texture and effective formula that mixes well in a simple shaker bottle." The nitric oxide (NO) "pump" ingredient agmatine has an unappealing taste, according to Kneller, who said a typical dose of a gram or more per serving means the fl avor is diffi cult to hide. The same goes for certain stimulants. "In general, virtually all the 2-phenylethylamine backboned 'stimulants' tend to be truly vile from a taste perspective," Kneller noted. The fl avor-masking challenges don't end there. One of the growing trends in energy and body composition is the ketone diet, which involves very low carb intake. As the body is starved of carbs, which typically drive the bulk of early mitochondrial energy production, ketones can accumulate and drive later energy production where fat is more rapidly oxidized for fuel. One ketone, beta hydroxybutyrate (BHB), is a popular supplement ingredient. Kneller said, BHB salts are exceedingly challenging to use in powder formulations despite their current popularity and ubiquity. "These ingredients taste really bad (sour, bitter), and they require a lot of masking agents, sweeteners and fl avorants to cover them up and make them even remotely palatable to the mainstream consumer." He said the challenge is amplifi ed by needing multi-gram amounts per dose of BHB salts to induce and maintain ketosis. "You have to add in a lot of 'stuff' to cover up the bad taste, and it gets expensive fast."

Helps the body provide increased levels of ATP via its own internal mechanisms Clinically shown to increase strength, power and performance in resistance-trained athletes* Kneller advised BHB salts pretty much limit fl avor options to citrus fruits like lemon/lemonade, orange, lime and other "acidic" fl avors. "I have seen chocolate BHB salt products; but in my opinion, they are absolutely disgusting and would make a Billy goat gag," he warned. In general, more bitter-tasting ingredients are limited to acidic fl avors. "This is why you don't see chocolate-milk-fl avored pre-workout products," he noted. "You just can't mix a good chocolate—a rich, creamy fl avor—with these nasty, bitter/acidic fl avors. Ever see anything but a fruit-fl avored BCAA product? Now you know why! There is no market for 'chocolate-covered lime fl avor.'" Plant-based ingredients can also be a big challenge. "High inclusions of botanicals can be diffi cult to overcome from a sensory standpoint and can be challenging to mask the herbal notes as well as limit color options," Laffey reported. "Green tea is a popular dietary ingredient, due to its myriad health-promoting benefi ts," Kneller said. "The higher the catechin content, the 'healthier' it is, but the nastier it tends to be from a taste perspective." "We try to use encapsulated forms of micronutrients when possible to help mask potential bitter notes," Laffey said. "Ingredients such as theacrine, copper, iron, methyliberine, capsinoids, etc., come to mind." Powder Innovations The road ahead for sports powders includes technological innovations that would allow for the use of ingredients that currently are challenging to include in powder formulations. To this end, fl avor masking and increased stability are other ripe areas for protein powder innovations, according to Kneller. One example is when Glanbia adapted its vegetable protein fl avor-neutralizing technology, EasyFlav™, to work on whey protein. EasyFlav can cut carbohydrate content by 30 percent with added protein and stable fl avor, according to the company. It saves time by reducing the need for separate protein and fl avor solutions. A recent innovation in protein powder is Velositol ® , which has been shown to boost the MPS ability of protein supplements (J Int Soc Sports Nutr. 2017;14[6]). Nutrition 21 designed this patented amylopectin chromium complex to enhance insulin response to boost amino acid uptake and provide muscle fuel. Following a trend in powder innovations, Velositol is fl avorless and accepts fl avor easily, according to Nutrition 21. Bill Levi, vice president of operations at Nutrition 21, noted Velositol and the company's arginine silicate Nitrosigine ® are easy-to-formulate powdered ingredients. "Neither Velositol nor Nitrosigine negatively interacts with other ingredients, and they both are simple to fl avor." Sports powders are poised to maintain and grow in popularity across consumer groups and athletic goals, especially as fl avor and stability technology improve, and novel ingredients become available in fl avorless or fl avor-friendly forms that bear many trendy designations from organic and gluten-free to clean label and non-GMO.
