You can get more iron by eating red meat, fish, and citrus fruits. Iron supplements should cap out at 15mg daily for women and 10mg daily for men. Athletes can handle a bit more, but it’s best to check with your doctor for a specific dosage 21StrongFoundation.org.
Vitamin D strengthens bones by regulating your body’s calcium and is one of the best vitamins for athletes. When athletes take vitamin D supplements, they also build stronger muscles. This benefit makes it less likely that they’ll get injured while working out or playing.
While you might have heard that low-carb diets help athletes, the body of scientific evidence just doesn’t support that.9 Rather, getting enough carbs is crucial for optimizing your performance, recovery, and body composition.

Skeletal muscle glycogen stores are a critical element to both prolonged and high-intensity exercise. In skeletal muscle, glycogen synthase activity is considered one of the key regulatory factors for glycogen synthesis. Research has demonstrated that the addition of protein in the form of milk and whey protein isolate (0.4 g/kg) to a moderate (0.8 g/kg), but not high (1.2 g/kg) carbohydrate-containing (dextrose-maltodextrin) beverage promotes increased rates of muscle glycogen replenishment following hard training . Further, the addition of protein facilitates repair and recovery of the exercised muscle . These effects are thought to be related to a greater insulin response following the exercise bout. Intriguingly, it has also been demonstrated that whey protein enhances glycogen synthesis in the liver and skeletal muscle more than casein in an insulin-independent fashion that appears to be due to its capacity to upregulate glycogen synthase activity . Therefore, the addition of milk protein to a post-workout meal may augment recovery, improve protein balance, and speed glycogen replenishment.

In conclusion, added protein does not appear to improve endurance performance when given for several days, weeks, or immediately prior to and during endurance exercise. While no ergogenic outcomes may be evident, the scientific literature is consistent in reporting that adding protein to a carbohydrate beverage/gel during exhaustive endurance exercise suppresses markers of muscle damage (creatine kinase) 12 to 24 h post-exercise and decreases the endurance athletes’ feelings of muscular soreness . For these reasons, it seems prudent to recommend for endurance athletes to ingest approximately 0.25 g of protein/kg body weight per hour of endurance exercise (in addition to the athlete’s regular carbohydrate intake) to suppress markers of muscle damage and improve subjective feelings of muscular soreness . Another important consideration relates to the impact of ingesting protein along with carbohydrate on rates of protein synthesis and balance during prolonged bouts of endurance exercise. Beelen and colleagues determined that adding protein to carbohydrate consumption throughout a prolonged bout of endurance exercise promotes a higher whole body net protein balance, but the added protein does not exert any further impact on rates of MPS. While performance outcomes were not measured, these results shift the focus of nutrient ingestion during prolonged bouts of endurance exercise to the ingestion of carbohydrate.

There are also reports that certain brands will have the Informed Sport logo on packaging for products that do not necessarily undergo testing and also the logo may be used on brand websites when only certain products in their range are tested.
Beta-alanine is another potentially beneficial nutrient for soldiers. Beta-alanine has been shown to reduce muscle soreness and neuromuscular fatigue, two important factors that limit high-intensity exercise.
The frequency of testing is the key difference between Informed Sport & Informed Choice. Before a product can be sold, Informed Sport tests each batch. Informed Choice tests its products monthly on a blind test schedule.
Established by one of the world’s premier doping control laboratories in 2008, LGC established informed Sport as a globally acclaimed banned substance testing and certification programme for sports supplements.
