  1. NANP Professional Members are eligible to apply to take the exam to become CDSP™ certified without an additional educational program of study. Professional members must complete the online application and pay the $50 application fee and $100 examination fee.
  2. If you are not a Professional Member of the NANP or do not qualify for Professional Membership, be sure to consult your scope of service/practice to ensure your legal ability to recommend dietary supplements.


The CDSP™ exam is intended to test for entry-level knowledge and skill in dietary supplements.

Preparation for the CDSP™ exam can start as early as the day you enter a NANP-approved educational program. Maintaining a compilation of key concepts as you progress through your education creates a simple means of reviewing dietary supplements basics. However, due to time constraints, many people begin their more targeted exam preparation immediately following graduation from their study program. Two to three months of focused study time provides adequate preparation for most people.

NOTE: Professional members of the NANP are not required to earn additional education or enroll in a Dietary Supplement Educational program. However, we strongly suggest studying for the exam as explained above.

There is no better way to prepare for the exam than by downloading the Certified Dietary Supplement Professional™ Study Guide. We suggest you start here.
