Supplements for Training: A Decision Checklist
A useful supplement decision starts with a specific problem and credible evidence. It should include suitability, cost, safety and whether ordinary food can meet the same need.
Define the job
A protein powder is a convenient food option; it is not automatically needed when meals already provide enough protein. A stimulant and creatine have different intended roles and should not be treated as interchangeable energy products.
Check the actual product
Read the ingredient list and avoid assuming a brand name proves quality. Athletes should seek sports-dietitian advice on current anti-doping rules and independent batch testing.
Review rather than accumulate
Record why a product was chosen and what outcome would justify keeping it. Stop adding ingredients just because the training program is inconsistent. Medication and medical conditions change suitability.
