Item 4.01 Change in Registrant’s Certifying Accountant

On December 11, 2013, the Audit Committee of the Board of Directors (the “Board”) of Chromadex Corporation (the “Company”) approved the dismissal of McGladrey LLP (“McGladrey”) as the Company’s independent registered public accounting firm.

During the fiscal years ended December 29, 2012 and December 31, 2011, McGladrey’s reports on the Company's financial statements did not contain an adverse opinion or disclaimer of opinion, and were not qualified or modified as to uncertainty, audit scope or accounting principles, except to the extent disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on November 21, 2013.

During the fiscal years ended December 29, 2012 and December 31, 2011 and the subsequent periods through December 11, 2013, (i) there were no disagreements between the Company and McGladrey on any matter of accounting principles or practices, financial statement disclosure, or auditing scope or procedure, which disagreements, if not resolved to the satisfaction of McGladrey, would have caused McGladrey to make reference to the subject matter of the disagreements in connection with its reports on the Company's financial statements; and (ii) there were no reportable events as that term is described in Item 304(a)(1)(v) of Regulation S-K, except (i) to the extent disclosed in the Company’s Current Report on Form 8-K filed with the Securities and Exchange Commission on November 21, 2013, (ii) McGladrey’s letter to the Audit Committee of the Board, dated November 21, 2013, in which McGladrey identified a material weakness in the Company’s internal control over financial reporting, and (iii) McGladrey’s audit report for the year ended December 31, 2011 stated that, in McGladrey’s opinion, the Company and its subsidiaries had not maintained effective internal control over financial reporting as of December 31, 2011.

On December 11, 2013, the Company provided McGladrey with a copy of the disclosures it is making in response to Item 4.01 on this Form 8-K, and requested that McGladrey furnish it with a letter addressed to the Securities and Exchange Commission stating whether it agrees with the above statements.  A copy of the letter, dated December 17, 2013, is filed as Exhibit 16.1 (which is incorporated by reference herein) to this Current Report on Form 8-K.
