The RFU always advises a food-first approach to nutrition, as there are no guarantees that any supplement product is free from prohibited substances. Players can support their training and progress towards their targets by eating and enjoying nutritious food.
Players should assess the need, the risks and the consequences before deciding to take a supplement, and if they need to use one, visit the Informed Sport website to check whether supplements have been batch-tested.
More advice on managing supplement risks can be found on Food for Rugby and on UKAD’s Supplement Hub.
