Supplement Safety & Information

Using supplements responsibly

Food supplements are designed to complement a varied, balanced diet. They are not medicines and should not be used to diagnose, treat or prevent a medical condition.

Before buying

  • Read the complete ingredient list and allergen information.
  • Compare serving sizes, not just the number on the front of the pack.
  • Check whether you already take another product containing the same nutrients.
  • Pay particular attention to high-dose vitamins, stimulating ingredients and herbal extracts.

Speak to a healthcare professional first if

  • You take prescription or over-the-counter medicines.
  • You are pregnant, breastfeeding or trying to conceive.
  • You have a diagnosed health condition.
  • You are buying for a child.
  • You have surgery or laboratory tests planned.

Important examples

High-dose biotin can interfere with some laboratory test results. Vitamin K can be relevant for people taking anticoagulants. Total vitamin D intake should include every supplement you use, not only one product.

Always follow the product label. Stop using a product and seek appropriate advice if you experience an unexpected reaction.
