Using a supplement

Follow the directions for your exact product

Find the product name on the front of the bottle, then open that product page. Use the current label and product-page directions because serving sizes and formulations can change.

Find My Product Ask Customer Support

Have the bottle nearby: Include the full product name and lot number when asking about a specific bottle. The lot number is printed on the bottle.

Special situations

Check before combining products or medications

Review the label for every product you plan to use and compare the Supplement Facts panels for overlapping ingredients. Product instructions can answer general questions, but your prescriber or pharmacist should help with questions involving your medications, medical conditions, pregnancy, or breastfeeding.

Compare Supplements Ask a Product Question

Make your question easy to answer: Send the product names, your current medications or supplements, and the exact concern you want clarified.

Where do I find allergen or gluten information?

Open the page for the exact product and review its current label and ingredient information. Contact Customer Support with the product name if anything is unclear.

How quickly should I expect a result?

Experiences vary by product and person. Review the expectations on the exact product page and use the product consistently according to its directions.
