Overview
A clear starting point
Vitamins and dietary supplements include a wide range of products such as vitamins, minerals, herbs, amino acids, and enzymes. While a balanced diet is the best way to obtain essential nutrients, supplements can help individuals meet specific nutritional needs or address deficiencies. However, they are not a substitute for healthy eating and are not intended to diagnose, treat, cure, or prevent any medical conditions. It is important to understand that supplements can interact with prescribed medications and may pose risks if taken in excessive amounts. Consulting with a healthcare provider before starting any new supplement is recommended to ensure it is appropriate for your individual health circumstances.

When professional care may be important
These examples are not a diagnosis checklist. New, severe, rapidly worsening, or concerning symptoms should be assessed by a qualified healthcare professional; emergencies require local emergency services.

- Consult a clinician if you develop unusual symptoms like severe nausea, vomiting, or dizziness after starting a new vitamin regimen.
- Discuss your supplement intake with a doctor immediately if you notice changes in how your prescribed medications are working.
