Currently, we utilize the entire turmeric root to make our formula. Using the whole source is essential because although curcumin is beneficial, it's more effective when combined with the various co-factors found in turmeric, just like nature intended. Also, since we use the entire root, we don't necessarily have the curcumin or compound breakdown per serving. We sincerely apologize for this inconvenience. However, please note that the serving size does not speak to the effectiveness of our product. What goes into the manufacturing process and how bioavailable it is are also critical factors to consider. Here you have information on our state-of-the-art raw herbal extract technology: https://www.globalhealingcenter.com/natural-health/raw-herbal-extract-technology. If you still choose to try Turmeric for yourself, please know that we always offer free shipping in the US and Canada and a one-year money-back guarantee in case you're not completely satisfied with your purchase.
