General information, individual decisions
Evidence for Supplements provides general educational information about supplement research. It does not provide personal medical advice, diagnosis or treatment. Reading this website, subscribing to the newsletter or contacting the publication does not create a clinician–patient relationship.
Research findings may not apply to your circumstances. A dose used in a study is not an individual prescription, and a review of an ingredient does not establish the quality, safety or effectiveness of every product containing it.
Before taking a supplement
Discuss supplements with your doctor or pharmacist, particularly if you take medicines, have a medical condition, are pregnant or breastfeeding, are considering a supplement for a child, or have surgery planned. Supplements can interact with medicines and affect laboratory tests. Tell your treating clinician what you take.
Do not stop or change prescribed treatment, or delay seeking care, because of something on this website. Supplements do not replace appropriate medical care or a balanced diet.
Urgent concerns
This website and its contact form are not emergency services. For a medical emergency in Australia, call 000; elsewhere, use your local emergency number. Seek prompt clinical advice for a suspected serious adverse reaction.
Evidence and corrections
Evidence changes, and published material can contain errors. Review dates identify when an article was last assessed; they do not guarantee that it includes every subsequent study. Use the Contact page to report a concern.
