If an athlete is not eating well, supplements can be helpful, but no amount of supplements will compensate for a poor diet. Quality food works best!
Supplements are used for different reasons!
• To prevent/treat nutrient deficiency. Specific nutrients of concern include iron, calcium, and vitamin D
• To provide energy. Commercial sports drinks, gels and liquid meals are often used before, during and after exercise. They are a convenient alternative to common foods.
• To support health and limit illness. Supplements with research to support their health claims, include probiotics, vitamins C and D.
• To improve performance. Only a few performance-enhancing supplements have research showing they “work”. You may see some benefit from caffeine, creatine monohydrate, dietary nitrate, sodium bicarbonate and beta-alanine.
Even among supplements with credible research, the response varies greatly from person-to-person due to genetics, biology, the placebo effect, adequate fuel and sleep.
To guide your food and supplement options:
• Consult with a health professional or registered dietitian (RD). Look for a professionals certified as a specialist in sports dietetics (CSSD).
• Supplement makers are not required to prove safety of their products. You want to use only supplements that offer NSF Certified for Sport, as found on the supplement’s label.
