JillLebofsky publishes general information about dietary supplements. Nothing on this site is medical advice, diagnosis or treatment. Our editor is not a doctor or any other kind of medical professional. Talk to your doctor or pharmacist before you start, stop or change any supplement, especially if you take medicine or have a health condition.
Is JillLebofsky medical advice?
No. Our reviews explain what a supplement label says, what published research has found about its ingredients, and what the seller's price and refund terms are. That information can help you prepare questions for your doctor. It cannot tell you whether a product is safe or useful for your body, your medicines or your health history.
Do not delay seeing a doctor, or ignore medical advice, because of something you read here.
Who writes our content?
Reviews are edited by Claire Hadley, our Reviews Editor. Claire reads labels, research summaries and refund terms. She is not a doctor, dietitian, nurse or pharmacist, and JillLebofsky does not have medical professionals on staff. Our reviews are desk research. We do not take or test the products ourselves. The how we review page explains the method.
Why should you talk to a doctor first?
Supplements contain active ingredients, and active ingredients can cause problems. Some supplements interact with prescription drugs, including blood thinners, diabetes medicine and blood pressure medicine. Some are not safe during pregnancy or breastfeeding, for children, or before surgery. A doctor or pharmacist who knows your history can check these risks. We cannot.
The NIH Office of Dietary Supplements publishes a plain guide to what consumers should know before taking supplements, and NCCIH has fact sheets on many herbs and ingredients.
Are supplements approved by the FDA?
No. The FDA does not approve dietary supplements for safety or effectiveness before they are sold. Companies are responsible for making sure their products are safe and their labels are truthful. The FDA's dietary supplements page explains how supplements are regulated. A label also tells you what the brand says is in the bottle. It is not proof that an independent lab checked the contents.
Supplements are not meant to treat, cure or prevent any disease, and our reviews never claim they do.
What should you do if you have a reaction?
- Stop taking the product and contact your doctor.
- If symptoms are severe, call 911 or go to the nearest emergency room.
- You or your doctor can report the problem to the FDA through MedWatch.
Can we answer your health questions?
No. We do not answer personal medical questions by email or any other way, because we are not qualified to and we do not know your history. You can still write to us about errors in a review through our contact page.
Is the information always current?
We work to keep reviews accurate and update them when labels, terms or research change, as described in our editorial policy. Research moves, labels change and mistakes happen, so we cannot promise every page is complete or current on the day you read it. Use of this site is also covered by our terms of use.
