Sports nutrition is a fast growing business with proteins, energy gels and nutritional supplements being popular sports nutrition products used only by bodybuilders and athletes that are used by the majority of the population today. The guarantees of improved performance include encouraging factors to purchase alternative diets for results. Lack of regulation of supplements and quality control can result in poor and inefficient products being used.

It measures that between 39 and 89 percent of the international nutritional supplement market is the highest prevalence among senior and elite athletes.

Research by Mintel has found that one in four, 24% of UK citizens, has used a sports nutrition product in the past three months, with the highest percentage being 42% of men aged 16 to 24.

Sports supplements to improve exercise and athletic performance comes in a variety of forms, including tablets, capsules, liquids, powders, and bars. Most of these products contain numerous ingredients in varying combinations and amounts. The most common ingredients include amino acids, protein, creatine, and caffeine. By one estimate, retail sales are in the category “Sports Nutritional Supplements” amounted to $ 5.67 billion in 2016, or 13.8% of total revenue of $ 41.16 billion for dietary supplements and related nutritional products for that year.

What is a supplement?

Dietary supplements are considered to be a supplement to an already healthy diet. Energetic adults or athletes can add supplements to achieve nutritional values, improve nutritional deficiencies, improve athletic performance, or meet personal fitness goals. Without a well-developed nutrition plan, nutritional supplements should rarely make sense.

Supplementary regulation and standards

Dietary supplements have been classified into a special food category and are not considered medicinal products. Supplements are not expected to be submitted to the Food and Drug Administration (FDA) for regulation. While the FDA can review ingredients and health claims made on supplements, very few are reviewed. Manufacturers of sports supplements are allowed to make health-related claims with FDA approval, provided the product claims are factual and based on scientific evidence. Unfortunately, very few dietary supplements that claim ergogenic benefits are supported by clinical research. This gives the active adult or athlete no guarantee of the safety, effectiveness, strength, or purity of any dietary supplement for dietary or ergogenic purposes.

  • Dietary supplements include vitamins, minerals, amino acids, herbs, plant substances, extracts or concentrates from plants or foods. They are typically sold as capsules, tablets, liquids, powders or bars and must be clearly labeled as dietary supplements.
  • Ergogenic aids contain substances, drugs or techniques to improve athletic performance. They can vary from acceptable carbohydrate loading practices to “illegal and unsafe approaches like the use of anabolic-androgenic steroids”.

Additions to science categories:

Dietary supplements and ergogenic aids are sold and are intended to intensify the diet and athletic performance of an active adult or athlete. Clinical research reveals deficiencies in these supplementary health claims. The International Society for Sports Nutrition (ISSN) has established a nutritional supplement department based on clinical research:

  • Apparently effective: Most complementary research studies prove safe and effective.
  • Possibly effective: Initial conclusions about the supplement are good, but more research is needed to examine the effects on exercise and athletic performance.
  • Too early to say Complementary theory makes sense, but there is insufficient research to support its use.
  • Apparently ineffective: Supplements lack solid scientific evidence and / or analysis has indicated that the supplement is clearly ineffective and / or unsafe.

The International Society for Sports Nutrition (ISSN) shows that the basis of a good training program is a balanced, nutrient-rich diet with balanced energy. When supplements are used, the ISSN only suggests Category 1 supplements (apparently effective). All other additions are considered experimental. They alert supplements in category three (too early to judge) and do not recommend athletes taking supplements in category four (apparently ineffective).

It is important to speak to your doctor before taking any supplements, vitamins, or medications.
Some things to consider before taking a supplement are:

  • Taking supplements does not make up for an unhealthy diet. No diet is perfect 365 days a year. Therefore, there may be times when a dietary supplement is important, e.g. B. during special training, an illness or if you suffer from an illness (pregnancy, anemia, etc.).
  • Many dietary supplements have done a great deal of research to demonstrate their benefit, but an even larger number lack sufficient evidence to support their use. Your doctor or nutritionist can help you figure out which supplements are healthy for you.
  • Unlike medications, dietary supplements are not intended to treat, diagnose, prevent, or cure any disease.

The U.S. Food and Drug Administration (FDA) has no way of verifying the safety and effectiveness of dietary supplements before they hit the market. To ensure you are choosing safe products, only buy products that have been identified as safe by a third party company such as the National Safety Foundation or Informed Choice. These groups have strict certification policies to prevent tampering, to check label information against the content and to ensure that it does not contain any banned substances.

Arginine:

Increases blood circulation and the delivery of oxygen and nutrients to skeletal muscle; serves as a substrate for creatine production; increases the secretion of human growth hormone to stimulate muscle growth.

research results: Little to no effect on vasodilation, blood flow, or exercise metabolites; little evidence of an increase in muscle creatine levels. No safety concerns have been reported for use up to 9 g / day for weeks. Side effects possible with larger doses

Reported side effects: Gastrointestinal effects such as diarrhea and nausea.
