Before you buy anything
- Food first. Food supplements are not a substitute for a varied, balanced diet. Sleep, training and meals matter more than anything on this page.
- Tested products if you compete. Supplements can be contaminated with prohibited substances, and under anti-doping rules the athlete is responsible. Batch-testing programmes such as Informed Sport reduce that risk.
- One at a time. Start one product at a time so you know what agrees with you.
