Bad for athletes: improving the results or harm to health?
I. Defining Dietary Supplements (БАДы) and Their Role in Sports
-
What are Dietary Supplements? (What are dietary supplements?)
Dietary supplements, or БАДы (Биологически Активные Добавки) in Russian, are products intended to supplement the diet. They contain one or more dietary ingredients, including vitamins, minerals, herbs or other botanicals, amino acids, and substances such as enzymes, organ tissues, glandulars, and metabolites. БАДы are intended to be taken orally as pills, capsules, tablets, liquids, or powders.
- Regulatory Status: It’s crucial to understand that БАДы are regulated differently than pharmaceuticals. In many countries, including Russia and the USA, they are not subject to the same rigorous testing and approval processes. Manufacturers are responsible for ensuring the safety of their products, but regulatory bodies typically don’t evaluate efficacy before they are marketed. This difference in regulation is a key distinction that impacts consumer choices and potential risks. The onus lies on the consumer to research and verify the safety and efficacy of specific БАДы.
- Distinction from Pharmaceuticals: While pharmaceuticals are rigorously tested for both safety and efficacy and are prescribed by medical professionals to treat specific conditions, БАДы are not intended to treat, prevent, or cure diseases. This fundamental difference should guide athletes’ understanding of their purpose and limitations. Blurring this line can lead to inappropriate use and potentially harmful health consequences.
- Global Variations in Regulation: The regulations surrounding БАДы vary significantly from country to country. What is considered a dietary supplement in one nation might be classified as a drug or even prohibited in another. Athletes competing internationally must be acutely aware of these differences to avoid unintentional violations of anti-doping rules and to ensure they are using products that are legally and safely available in their current location.

Who athletes use Dietary Supplements (why do athletes use dietary supplements?)
Athletes often turn to dietary supplements for a variety of reasons, primarily centered around enhancing performance, optimizing recovery, and addressing nutritional deficiencies. The pressures of competitive sports, combined with the desire to gain even a marginal advantage, can drive athletes to explore the potential benefits of these products.
- Performance Enhancement: This is perhaps the most prevalent motivation. Athletes seek supplements that promise to improve strength, power, speed, endurance, and overall athletic ability. Common examples include creatine, caffeine, and beta-alanine, which are believed to enhance specific aspects of performance. The perceived benefits, even if small, can be highly appealing in competitive environments.
- Recovery Optimization: Intense training regimes can lead to muscle damage, inflammation, and fatigue. Athletes often use supplements like protein powders, branched-chain amino acids (BCAAs), and glutamine to accelerate muscle repair, reduce soreness, and replenish depleted energy stores. The aim is to recover faster and more effectively, allowing for more frequent and intense training sessions.
- Nutritional Deficiencies: Athletes, due to their high energy expenditure and specific dietary needs, may be at risk of developing certain nutritional deficiencies. Supplements like iron, vitamin D, calcium, and magnesium are commonly used to address these potential gaps and ensure optimal health and performance. However, it’s crucial to identify actual deficiencies through blood testing rather than blindly supplementing.
- Weight Management: Some athletes use supplements to aid in weight loss or gain, depending on the demands of their sport. Fat burners, appetite suppressants, and weight gainers are examples of supplements marketed for these purposes. However, the efficacy and safety of many of these products are questionable, and they should be approached with caution.
- Psychological Edge: The placebo effect can play a significant role. Athletes may believe that a particular supplement is helping them perform better, even if the actual physiological effect is minimal. This belief can boost confidence and motivation, leading to improved performance through psychological mechanisms.
