What it is
Supplements include vitamins, minerals and other ingredients taken in addition to food. They may help meet specific needs, but they are not a complete eating plan.
Why it matters
Products vary in evidence and quality. They can interact with medicines, and larger doses are not automatically more useful.
Practical guidelines
- Start with the reason for taking a product rather than its marketing.
- Check the ingredients, amount per dose and overlap with other supplements.
- Ask a qualified professional about a suspected deficiency or possible medicine interaction.
Common mistakes
- Assuming a natural ingredient is always safe.
- Using supplements instead of addressing gaps in everyday meals.
Keep it simple
Choose supplements for a clear purpose, with appropriate advice—not as a substitute for food variety.
