Recommending the best supplements for athletes

Abby Kass April 28, 2016

supplements for athletes

Training as an athlete requires hard work and dedication.

It also requires rich nutrients to support the body. These nutrients can come from a healthy diet, and also from supplements. Supplements can help increase endurance, speed, power and even strength. Although there are many different supplement out there for athletes, here are six that can help improve performance.

Creatine

One of the most popular supplements, creatine is also one of the most widely-researched. It is a chemical that is found in the muscles of the body. Creatine can be made in the body, but it can also be found in certain food such as meat and fish. Studies have shown that creatine can improve athletic performance and muscular endurance in adults. A 2007 study by the NRC Research Press found that rugby players had a great muscle endurance after taking creatine supplements for eight weeks. The study also showed that creatine did not improve body composition or aerobic endurance.1 While the use of creatine has had an effect on athletes and young people, the U.S. National Library of Medicine says that creatine is not an effective supplement in adults over 60.2

Fish oil

There are two very important omega-3 fatty acids in fish oil: docosanexaenoic acid (DHA) and eicosapentaenoic acid (EPA). Both of this acids have anti-inflammatory properties that reduce on-set muscle soreness after a workout. Fish oil is an important supplement because humans are unable to synthesize omega-3 fatty acids and can only get it from food including fish and nuts. Omega-3 fatty acids stimulate the breakdown of muscle protein and can improve oxygen uptake in endurance athletes. A 2011 study in the American Journal of Clinical Nutrition found that in older adults, omega-3 fatty acids helped increase the syntheses of muscle protein and also helped to stop the loss of muscle tissue.3

Iron

As one of the most abundant metals on earth, iron is an essential component in hemoglobin. It is also essential in producing ATP, the body’s primary energy source. There are two types of iron, heme and non-heme iron. Heme iron is absorbed better in the body and can be found in lean meets such as beef, clams, organ meats, and oysters. Non-heme iron, found in dark greens, is harder for the body to absorb. According to an October 2015 study in Swiss Medical Weekly, iron deficiency is often prevalent in athletes. Iron deficiency may negatively affect physical performance including endurance. The study suggest that elite athletes should consume 50 mcg/l before training.4 If an athlete has iron deficiency, he or she should take iron supplements. But, taking iron supplements without an established iron deficiency can cause more harm.

Caffeine

Caffeine might be the stimulant that wakes you up in the morning, but it also has ergogenic acid that can be a helpful stimulant for athletes. Caffeine may not have nutritional value, but it does release endorphins during workouts that can improve endurance. A 2008 study in the American College of Sports Medicine found preliminary results that caffeine had the power to increase performance in both single and multiple sprint sports.5 While a lot of research has been done, there still needs to be more investigation on the full effect of caffeine on athletes.

B-Vitamins

B-Vitamins include riboflavin, thiamin, folate, and vitamins B-6, B-12. All of these vitamins are essential to covert proteins in the body into energy and also repair cells including red blood cells. Preliminary research supports idea that exercise may increase the amount of riboflavin and Vitamin B-6 needed in the body, especially for athletes that need to control their weight. Athletes that have a B-Vitamin deficiency will see a worse performance during high-intensity exercise and not be able to repair and build muscles. Oregon State University in 2006 found that athletes need more B-Vitamins in their diet than recommended by the U.S. Government.6 B-Vitamins can be found in dairy, meat, and also whole grains, dark green vegetables and nuts.

Vitamin D

Known for its presence in ultraviolet rays, vitamin D is an essential vitamin for everyone. vitamin D is a fat-soluble vitamin, and small traces can be found in foods. More than 77 percent of the population has a vitamin D deficiency. While it is important for everyone to have more Vitamin D in their diets, it is especially important for athletes. vitamin D helps regulate calcium and bone health in the body. It also may play an important role in muscle function and structure. A study by MDPI in 2013, found that there was not enough evidence to prove Vitamin D acted as a performance enhancer, but in vitamin D deficiency athletes it does help prevent stress fracture and also muscle injury.7
