A multivitamin is not essential for every athlete; it is most relevant with a restricted diet, confirmed deficiency or specific need. An informed choice considers diet, relevant testing and the risk of excessive intake.
Quick answer
A multivitamin cannot replace energy, protein, fruits, vegetables or sleep. Some products contain multiples of daily needs, and stacking supplements can create excessive intake. Selection should reflect diet and professional assessment. A supplement is useful when it addresses a defined need at an appropriate, monitorable dose.
What matters
- Do not diagnose deficiency by guesswork.
- Read the active amount on the label.
- Count food and supplement intake together.
- Higher doses are not always better.
- Medical conditions and medicines need review.
A practical approach
- Review the goal and current diet.
- Use appropriate testing or assessment when needed.
- Choose a simple independently tested product.
- Use an appropriate amount for a defined period.
- Reassess outcomes and adverse effects.
