Food supplements

The World Anti-Doping Code is unambiguous: athletes are responsible for their consumption in case of control. It is therefore fundamental for them, as for their management, to ensure that the medicines and food supplements that are dispensed to them do not contain prohibited substances. What is, for dietary supplements, much more common than what is commonly accepted. Not to mention the health risks that repeated intake of these foods can cause.


The food supplement does not comply with the specifications or its manufacturing process endangers its integrity through cross-contamination or even voluntary contamination with doping products.

There are many cases where doping molecules on the list of banned substances have been found in food supplements. Studies have shown that between 15 and 25% of food supplements sold contain doping substances not reported in the package leaflet. This is usually:

A problem of quality

The manufacturing process does not ensure the integrity of the food supplement that can be brought into contact, sometimes voluntarily, with prohibited substances.

An incomplete labeling

The composition of the supplement is not exhaustive and does not indicate the presence of a potentially prohibited ingredient.

The consequences for the athlete can therefore be dramatic without his moral integrity ever being challenged in the process.

A positive control

If the food supplement contains doping molecules, even without the knowledge of the athlete, he will be considered responsible and penalized.

A risk to health

The quality of a food supplement with traces of doping product (s) is seriously questionable. In addition to the dramatic consequences on the athlete’s health that the presence of prohibited substances may cause, there is also a high probability that it is falsified and / or adulterated.

A Harmful overconsumption

The risk is also great that the prolonged consumption of such food supplements causes dangerous interactions, with potentially serious adverse effects.

Food supplements, as their name suggests, are foods whose function is to complete a normal diet. It is a concentrated source of nutrients (minerals and / or vitamins) or other products, herbal or plant extracts.

In most cases, they are presented in the form of tablets, capsules, powder or ampoules. It is essential that their packaging bears the words « food supplement », lists the nutrients and substances contained and their quantity and indicates the recommended daily dose.

Since 2012, the AFNOR standard NF V 94-001 has been providing guarantees of reliability. By adhering to this standard, manufacturers has committed to ensuring that the manufacturing process makes it impossible to contaminate a substance on the WADA Prohibited List resulting in a positive control. Of course, all their ingredients are considered as non-doping products. This standard makes it easy to identify healthy food supplements, but it is not foolproof and depends on the goodwill of the manufacturers.

Be that as it may, food supplements are not foods like any other and should not be considered as such.


Food should be at the center of everyone’s attention in general and athletes in particular. It cannot be repeated enough how important it is to be balanced and varied. If this goal is achieved daily, the intake of essential nutrients will be largely sufficient to meet the needs of a healthy athlete.

Few sports practices (very high energy expenditure, extreme climatic conditions, etc.) require additional vitamins and minerals. In these cases, it is strongly recommended to turn to a health care professional specializing in sports nutrition. He will know how to best develop a healthy strategy for food supplements adapted to his real needs.


To guarantee his offer

It is important for a pharmacist to make an offer for guaranteed food supplements without doping products. For more legibility, it is interesting to group all products for athletes around a single place. It is also important for pharmacists to be openly involved in the fight against doping, by showing their commitment to the fight with posters or signage, for example. Monitoring on the subject is also important.

To identify

The problem of doping must be at the heart of the concerns of prescribers when dispensing a drug or a food supplement. It is advisable to encourage, by posters in particular, the athletes to come forward.

To understand

It is important to properly understand an athlete’s request:

  • Who is it for? Him?
  • When is it for? How long?
  • For what? For a sports event or for a training?

To recommend

A varied and balanced diet, in the vast majority of cases, can cover the needs of athletes for essential nutrients. Athletes too often tend to forget it and it is worth remembering them.

To guide

The biggest enemy of the athlete is self-medication, even, perhaps especially, when it comes to food supplements. It is therefore beneficial to provide those athletes with appropriate referral to a health care professional specializing in sports nutrition.

To monitor

One of the major dangers of food supplements is their possible interactions with other nutrients and other medications. The side effects can be dramatic. It is thus advisable to talk to athletes about the other products they take.

To raise awareness

Even though they are not prescribed, food supplements are not foods like any other. Thus, the athlete must be reminded that:

  • the risks related to the purchase of unauthorized food supplements on the Internet without guarantee are great,
  • the possibility of being declared positive to a doping control is significant,
  • some standards may protect against these risks but do not make them non-existent,
  • contamination with noxious substances is a major problem,
  • overdose and interactions are not to be taken lightly.
