TRISHA STAVINOHA, MS, RD, CSSD, CSCS PICK YOUR PROTEIN P rotein supplements alone are a $7 billion industry (2). Selecting a protein supplement is of particular importance in the military since protein makes up the second most frequently used supplement in military populations (multivitamins are the most common supplement) (6). Protein supplements are not tested for safety, quality, or purity by the Food and Drug Administration (FDA) or any federal or state agency prior to sale. A 2010 review found that 31% of selected protein supplements failed quality testing (6). Additionally, Forbes Magazine recently published an article shedding light on how some protein supplements may contain far less protein than what is listed on the label (2). For example, the label for one such protein supplement claimed that it contains 27 g of protein, however, third party testing confirmed the product only contains 12 g of protein. This is partly due to companies using the weight of amino acids to contribute to the entire protein content. In the aforementioned example, the product may have contained 12 g of protein, plus 15 g of amino acids to equal 27 g of “protein.” This is of particular concern to the tactical population because incorrectly labeled products could result in either a protein deficiency or overuse. Considering this, using supplements that have been third party tested can help in avoiding poorly made products that contain potentially dangerous contaminants. Before taking a protein supplement, the tactical athlete should determine if protein supplementation is even needed. Most tactical athletes need about 1.5 – 2.0 g of protein per kg of bodyweight for active military personnel or 0.8 – 1.5 g per kg of bodyweight for the average tactical athlete (4). The concern is less about how much protein the athlete is getting, but how it is spread out over the course of the day. Athletes should keep a food log for a couple of days. This log may be a simple pen-and-paper diary or one of the many food log websites or phone/tablet applications. They should then review not only their total daily protein intake, but also how it is spaced. This will also allow them to determine if their protein intake is sufficient, particularly after workouts. A protein intake of 120 g is better utilized in four 30-g doses as opposed to two 60-g doses (1). 45 g per drink. The ideal dose of protein is 20 – 40 g per serving (1). If the product is 100% protein or has very little carbohydrates, a recommended intake method is to mix the protein powder with almond milk, juice, or a sport drink for some additional carbohydrates, if additional carbohydrates are deemed necessary. If it is a ready-to-drink supplement, an intake option could be to pour the drink over dry cereal or drink it with a fruit. Many protein bars, protein powders, and ready-to-drink protein products already contain sufficient carbohydrates, but again, the tactical athlete should take time to verify the accuracy of the label before assuming it is correct. Choosing unprocessed food is another viable option; however, some protein foods need to be kept cold and may not be as convenient as previously mentioned options. The final consideration, and most critical to safety, is to select a reputable brand. Most retail and online supplement stores have well over 100 protein supplement options. NSF International® is an organization that conducts third party testing on a variety of supplements, including protein (3). Supplement companies pay a fee to have their products tested and inspected. If they pass, they are then officially “certified for sport.” Supplements on this list have a low risk of being contaminated with banned substances such as steroids or other drug products (3). Additionally, consumers can be confident that the amount of protein on the label matches what is in the actual product. The list is updated regularly and includes brands that are available at most retail stores. It is worth noting that just because one product from a particular brand is certified, it does not mean that all products from that brand are certified. Another resource that tactical athletes can use to evaluate supplements is consumerlab.com. They have reviews on protein supplements and protein/meal bars, which are not technically considered supplements, but may have issues with quality (5,6). If the athlete is falling short of protein requirements or needs a convenient option for post-workout protein, then a protein supplement may indeed be warranted. Conversely, if the athlete is getting enough daily protein but just not enough specifically after the workout, the athlete should aim to distribute the doses evenly throughout the day and base some of their intake according to the time of the workout. Table 1 provides an example of a modified meal plan to spread protein intake out throughout the day efficiently while accommodating for a workout. Types of protein to choose from that are considered complete proteins (i.e., contain all nine essential amino acids) include whey, casein, soy, egg, pea, hemp, and combinations thereof. People looking to get more branched-chain amino acids (BCAA) should aim for whey protein. This form of protein is also found to be most effective with stimulating muscle protein synthesis (1). Those allergic to milk may want to choose egg or soy protein sources. Vegans can consume protein via soy, pea, or hemp products. However, military service members may be advised to avoid hemp products due to concern of consuming excess amounts of tetrahydrocannabinol (THC). Most products claim to have low levels of THC; however, neither consumerlab.com nor NSF International have hemp proteins on their list of reviewed products (3). Most protein powders contain 20 – 30 g of protein per scoop. Some ready-to-drink protein supplements will contain about 15 – Protein supplements can be a great way to improve protein intake, if necessary. To ensure safety and quality, tactical athletes should 4 NSCA’S TSAC REPORT | ISSUE 38 VERY LONG ARTICLE TITLE GOES HERE PICK YOUR PROTEIN AND TAKES UP LOTS AND LOTS OF ROOM never assume that all products are risk-free and try to only select products that have undergone and passed a third party review.
