Dekkers J, et al. There are two main forms of calcium supplements, if supplementation is needed: carbonate and citrate. Fletcher R, Fairfield K. Vitamins for chronic disease prevention in adults: Clinical applications. For example, nutritional shakes and bars can have large amounts of certain micronutrients that could cause an athlete to meet or exceed their needs without supplementation. The same could be said for supplements: You cant out-supplement a poor diet. Initial evidence of supplement contamination was established in a 2004 market survey from an International Olympic Committee accredited lab, during which 15 percent (94) of the 634 supplements analyzed were found to contain hormones or prohormones not listed on the supplement label.

Vitamins B1, B6 and B12 are believed to affect the formation of serotonin, an important neurotransmitter involved in relaxation. Vitamin D can be absorbed from exposure to sunlight, however, the season, time of day, cloud coverage, as well as an individual's geographic location and skin color all can affect how well vitamin D is absorbed from ultraviolet light. While there certainly are supplements that are safe and pure, it is possible for one batch of a product, for example, to become contaminated with a dangerous or sport-prohibited substance when manufacturing equipment isnt cleaned properly and contains remnants of ingredients from a previous product. However, excess amounts of several vitamins may contribute to serious health problems and tolerable upper limits (UL) have been established for many vitamins. Choline is involved in the formation of acetylcholine, a neurotransmitter whose reduction in the nervous system may be theorized to be a contributing factor to the development of fatigue. Melinda Manore [37,38] noted that athletes involved in heavy training may need more of several vitamins, such as thiamin, riboflavin and B6 because they are involved in energy production, but the amount needed is only about twice the RDA and that may be easily obtained through increased food intake associated with heavy training. Even though it has been shown that a severely inadequate intake of certain vitamins and/or minerals can impair performance, it is unusual for an athlete to have such severe nutritional deficiencies. Part of the reason is because it is packed with nutrition. Frozen fruits and vegetables are picked at the peak of their ripeness (when they contain the most nutrition) and flash frozen. Additionally, the passing of DSHEA allowed manufacturers to publish only limited information about the benefits of dietary supplements. Summer Squash: Stuff It, Bake It, Grill It, Farmers Markets: Bringing the Farm to Table, Hiking and Camping with Food Safety in Mind. In terms of supplementation, B vitamins are water-soluble, thus are not stored in the body in the same way as fat-soluble vitamins. These programs may reduce the risk that a supplement is contaminated, or contains an undisclosed ingredient. In general, although a deficiency of the B vitamins may impair both aerobic and anaerobic exercise performance, supplementation has not been shown to enhance performance in well-nourished individuals. Sports success is dependent primarily on genetic endowment in athletes with morphologic, psychologic, physiologic and metabolic traits specific to performance characteristics vital to their sport. These provide a set of values used to plan and assess nutrient consumption and vary by age and gender. Chronic multivitamin-mineral supplementation does not enhance physical performance. It is easy for products to get to the marketplace without pre-market controls, and if necessary, they are extremely difficult to remove, even when serious health concerns are raised about their safety. PMC legacy view The role of antioxidant vitamins and enzymes in the prevention of exercise-induced muscled damage. Butternut squash: This orange vegetable is high in fiber and antioxidants. International Journal for Vitamin and Nutrition Research Supplement. However, it should be noted that such doses could exceed the Tolerable Upper Intake Level (UL) for vitamin B6.

Others have suggested that the beneficial effect was related to the role of these vitamins in promoting the development of neurotransmitters that induce relaxation [9]. bmi nutrition blueberry Iron depletion is typically related to inadequate energy intake. Both forms are well absorbed, but individuals with reduced levels of stomach acid can absorb the citrate form more easily. Hemoglobin and myoglobin are both oxygen-carrying proteins. We often tell our athletes you cant out-train a poor diet. They also may affect how well the body performs.

Whole grains: Grains, in their unrefined form, provide important vitamins and minerals as well as fiber. It has been hypothesized that frequent exercise produces a chronic oxidative stress on the muscles since exercise increases oxygen consumption, and thus ups the need for antioxidants. Most Americans are unaware that designer steroids and other dangerous drugs are intentionally being sold as dietary supplements and that current laws makes it too easy for these products to get to the market. Accessibility Calcium citrate is absorbed equally effectively when taken with or without food. Sen [26]indicates that strenuous exercise may generate reactive oxygen species (ROS) to a level to overwhelm tissue antioxidant defense systems. Avoid supplements marketed to burn fat, increase energy, or promise anything that sounds too good to be true.

Athletes who consume vitamin supplements should purchase them only from reputable companies, such as those whose products that carry the USP (United States Pharmacopeia) certification on the label. As athletes strive to get the right dosages of micronutrients, they need to be aware of the levels of vitamins and minerals in the fortified foods they consume. Choline, an amine, is found naturally in a variety of foods and its RDA is grouped with the B vitamins [2]. It may be the most-asked question sports dietitians get from athletes: How do I know if Im getting enough vitamins and minerals for optimal performance? With our student-athletes at Texas, the goal is that they meet increased micronutrient needs through food alone. For complete details, consult the treatises by the National Academy of Science [1-4]. Nuts: While nuts are high in fat, they provide unsaturated fats that have been shown to help decrease inflammation. Athletes searching for a competitive edge often look to a supplement or a special combination of nutrients to find it. 8600 Rockville Pike Journal of the International Society of Sports Nutrition. Antioxidants, particularly vitamins C and E, beta-carotene, and selenium, play important roles in protecting cell membranes from oxidative damage. Feeding the Student-Athlete: 4 Tips to Follow. FOIA If an athletes diet is adequate in calories and balanced most days with just some inconsistencies, I will often prescribe taking a multivitamin/mineral supplement every other day instead of daily. Since athletes have high rates of energy metabolism and need their bodies to function at intense levels, they tend to have higher micronutrient needs than non-athletes. The overall review of the literature supports the viewpoint that multivitamin/mineral supplements are unnecessary for athletes or other physically active individuals who are on a well-balanced diet with adequate calories. Iron deficiency, with or without anemia, can impair muscle function and limit work capacity. Some research with large doses (60200 times the RDA) of these vitamins has shown increases in fine motor control and performance in pistol shooting. In addition, exercise stresses the metabolic pathways where vitamins and minerals are utilized and may also result in biochemical adaptations that increase micronutrient needs. Necessary cookies enable core functionality. Thus, many athletes have turned to various dietary strategies, including the use of various dietary supplements (sports supplements), which they presume to be effective, safe and legal. There are other factors that can affect iron status, including following a vegetarian diet with poor iron availability, times of rapid growth in adolescence, training at high altitudes, and increased losses (sweat, urine, feces).

Multivitamin/mineral supplements are intended to fortify a strong nutritional foundation. Goldfarb [27] concluded that research findings, mostly conducted with vitamin C, vitamin E, and beta carotene, have indicated that clear evidence for their prophylactic effect on various types of muscle damage following exercise is lacking. Under DSHEA, the Food and Drug Administration (FDA) DOES NOT regulate any supplements including vitamins, minerals, amino acids, herbals, and other botanical preparations for safety or efficacy (whether they work). Other researchers [31] are convinced that vitamin E contributes to preventing exercise-induced lipid peroxidation and possible muscle tissue damage, and recommend that athletes supplement with 100200 milligrams of vitamin E daily to help prevent exercise-induced oxidative damage. Williams MH. A contemporary review indicated that although vitamin E supplementation may increase tissue or serum vitamin E concentration, most evidence suggests there is no discernable effect on training, performance, or rate of post-exercise recovery in either recreational or elite athletes [19]. 2022 eatright.org. Sen C. Antioxidants in exercise nutrition. Choose USADA Program Highlight: UFC Anti-Doping Program. van der Beek E. Vitamin supplementation and physical exercise performance.

The inclusion of stimulants in supplement products also has the potential for harmful effects. Right behind it come two more questions. Well-known for its role in vision, vitamin A also may act as an antioxidant. Others note that the prudent use of antioxidant supplementation can provide insurance against a suboptimal diet and/or the elevated demands of intense physical activity, and thus may be recommended to limit the effects of oxidative stress in individuals performing regular, heavy exercise. Benardot D, et al. She has been coaching athletes on all aspects of fueling for optimal performance and health for more than a decade. They also provide protein, fiber, potassium, vitamin E, and folic acid. Overall, a recent review [25] concluded that there is limited evidence that dietary supplementation with antioxidants improves human performance.

That leaves 20 percent of food choices for fun. Laaksonen R, et al. government site. Athletes can relate to this balance, and most find it doable.

One is a kale, oat, and blueberry smoothie and another combines butternut squash with quinoa, spinach, and walnuts for a hearty side dish. Choosing a multivitamin/mineral supplement can pose challenges due to limited regulation of dietary supplements. In some cases, here at Texas, individual nutrient supplementation, such as iron, calcium, or vitamin D, is recommended based on our protocols and my assessment of the athlete. For example, many B vitamins aid in energy being released from carbohydrates. In addition, whole grains have a lower glycemic index than other carbohydrates, which causes less of a spike in blood sugar levels and allows for a longer duration of satiety. HOWEVER, it does not eliminate this risk. In particular, Ji [33]notes that the aging process lessens the exercise training-induced improvement in natural antioxidant enzymes and suggests exercise training in older athletes might be assisted with antioxidant supplementation in attempts to optimize antioxidant defense. Vitamins function in the human body as metabolic regulators, influencing a number of physiological processes important to exercise or sport performance. Fat soluble vitamins (A, D, E, and K) can be toxic when misused. Instead, they can steam, blanch, microwave, grill, or roast. Even marginal deficiencies do not appear to markedly affect the ability to exercise efficiently. However, there are no quick-fix supplements for improving sports performance.

The effect of lecithin supplementation on plasma choline concentrations during a marathon.

Endurance performance is impaired by magnesium deficiency because of increasing oxygen requirements to complete submaximal exercise. The more variety, the more likely it is athletes will satisfy all of their micronutrient needs. Address:5555 Tech Center Drive, Suite 200,Colorado Springs, CO, 80919.

Nutrients that may be low in an athletes diet are listed in Table 11. They include: Because some athletes are tempted to mega-dose on vitamins and minerals, thinking it will give them a performance boost, they need to be acutely aware of UL numbers. Obtaining adequate vitamins, including use of supplements, may also be prudent behavior for some athletes. Beans: Edamame, kidney, lentil, garbanzo, and black beans are considered an excellent source of both protein and carbohydrates. Taking a B12 supplement may also be needed but check with a health care provider first.

Often individual nutrients dont work as effectively when isolated in a pill or supplement form. But that can be difficult to achieve consistently. For example, choline supplementation, although increasing plasma free choline in marathon runners, had no effect on predicted or actual marathon time [11]. Strenuous and prolonged exercise has been shown to increase vitamin C needs from 100 to 1000 mg/day. International Journal of Vitamin and Nutrition Research. However, the athlete who takes a simple one-a-day type of vitamin or mineral that does not exceed the nutrient levels of the Recommended Dietary Allowance (DRA)/Dietary Reference Intake (DRI), is probably not doing any harm, especially if it is third-party tested. Amino acids, botanicals, herbs, and substances such as enzymes, organ tissues and glandulars, and metabolites, are also classified as dietary supplements.
