Chiropractic Board of Clinical Nutrition

The Chiropractic Board of Clinical Nutrition (CBCN) was founded in 2008 to continue the specialty board originally established by the ACA in 1986, and is the credentialing and certifying agency of the chiropractic profession.


To secure, protect, and advance clinical nutrition in the chiropractic profession while serving to enhance the health of the people we serve and the population at large.

The CBCN operates under the auspices of the American Chiropractic Association (ACA) and as a member of the American Board of Chiropractic Specialties with full autonomy in the areas of testing standards and procedures.

The CBCN is authorized and recognized to issue the specialty certification Diplomate (DCBCN) to Doctors of Chiropractic in the field of Clinical Nutrition.


A diplomate of the Chiropractic Board of Clinical Nutrition (DCBCN) is a licensed chiropractic physician who has successfully completed a post‚Äźdoctoral program in nutrition of at least three hundred (300) credit hours from a chiropractic college or university, institution, foundation or agency whose program is approved by an accrediting agency recognized by the U.S. Department of Education. The topics of study required are delineated in the bylaws of the CBCN. In addition, the diplomat has successfully passed the certifying examination administered by the CBCN.

DCBCN Brochure


Vitamin D:
Vitamin D is now listed in mcg. Vitamin D IUs may be listed voluntarily in parenthesis as well. Unit conversion: 1 mcg = 40 IU

Vitamin A:
Vitamin A is now listed in mcg of Retinol Activity Equivalents (RAE), which is a change in unit from the pre-existing label, where vitamin A was listed in IUs. The conversion from IUs to mcg RAE considers whether the vitamin A is coming from an animal source (retinol) or a plant source (carotenoids), or a combination of sources. We use plant-sourced carotenoids, which have higher RAE than retinol.

Vitamin E:
The nutrient measurement unit for vitamin E has changed from IU to mg of alpha-tocopherol. The conversion factor used depends on whether the source is from food or supplement.

Folate is now listed in mcg of dietary folate equivalents (DFE). The development of DFEs reflect the higher bioavailability of folic acid than that of food folate. At least 85% of folic acid is estimated to be bioavailable when taken with food, whereas only about 50% of folate naturally present in food is bioavailable. Based on these values, DFE can be calculated as follows:

Unit conversion: 1 mcg 5-MTHF or folic acid from dietary supplements = 1.7 mcg DFE
