Dietary supplements can be a useful addition to an athlete’s diet. There are numerous supplements on the market making bold claims to improve the performance and health of athletes. However, much of the evidence is anecdotal at best and many supplements contain ‘fillers’ and other ingredients, which could be detrimental to the athlete’s health and performance.
By far the best way to achieve sufficient levels of vitamins, minerals and other nutrients is from a well-balanced diet that meets your energy requirements. Getting the balance right is individual to each athlete and takes time. Seeking the advice of a trained nutritionist is the best way to ensure your diet is giving your body everything it needs.
Supplements may have a place in the athlete’s diet, however, some of them are nutritionally very poor and should never be solely relied upon to meet the increased nutritional needs of an athlete.
When choosing a supplement, choose products backed by clinical trial evidence and, because supplement use is tightly regulated in the UK, always make sure you check the UK Athletics website before proceeding to take a supplement.
