NOTICE OF ANNUAL MEETING OF STOCKHOLDERS

TO BE HELD November 5, 2026

Dear Stockholders:

Notice is hereby given that the fiscal year 2027 Annual Meeting of Stockholders (the “Annual Meeting”) of LifeVantage Corporation, a Delaware corporation (the “Company”), will be held in person on November 5, 2026, at 1:00 P.M. Mountain Time at our offices located at 3300 Triumph Blvd., Suite 700, Lehi, Utah 84043. At the Annual Meeting, we will ask you to:

Elect six directors, each to hold office for a term expiring at our next annual meeting of stockholders or until his or her respective successor is elected and qualified (Proposal 1);

Approve, on an advisory basis, a resolution approving the compensation of our named executive officers (commonly referred to as a “Say-On-Pay” proposal) (Proposal 2); and

Ratify the appointment of Deloitte & Touche, LLP (“Deloitte”) as our independent registered public accounting firm for the fiscal year ending June 30, 2027 (Proposal 3).

Stockholders may also transact such other business as may properly come before the Annual Meeting or any adjournment or postponement thereof.

The Company’s Board of Directors (the “Board”) unanimously recommends that you vote “FOR” the election of each of the six director candidates recommended by the Board in Proposal 1 and “FOR” Proposals 2 and 3.

The Board has fixed the close of business on September 14, 2026 (the “Record Date”), as the Record Date for determining the stockholders entitled to receive notice of and to vote at the Annual Meeting. Only stockholders of record at the close of business on the Record Date may vote at the Annual Meeting or any adjournment or postponement thereof. Additional details regarding the Annual Meeting, the business to be conducted, and information about the Company that you should consider when you vote your shares are described in this proxy statement.

We are taking advantage of the Securities and Exchange Commission rule that allows us to furnish proxy materials to our stockholders over the Internet. Instead of mailing printed copies of our proxy statement and Annual Report on Form 10-K for the year ended June 30, 2026 (the “Annual Report”), we are mailing a Notice of Internet Availability of Proxy Materials (“Notice of Availability” or “Notice”). We intend to mail the Notice of Availability to our stockholders on or about September 18, 2026. The Notice of Availability contains instructions on how to access on the Internet our proxy statement and Annual Report to stockholders and how to submit your vote online or by telephone. The Notice of Availability also contains instructions on how you can, alternatively, receive a paper copy of the proxy statement and Annual Report and a return, postage prepaid envelope. We believe this e-proxy process expedites stockholders’ receipt of proxy materials, lowers our costs associated with the Annual Meeting and reduces the environmental impact of our Annual Meeting.

Whether or not you expect to attend the Annual Meeting, your vote is very important. We encourage you to submit your proxy as soon as possible: (i) by accessing the Internet site; (ii) by calling the toll-free number described in the proxy materials; or (iii) by signing, dating and returning a paper proxy card as promptly as possible in order to ensure your representation at the Annual Meeting. Even if you have voted by proxy, you may still vote if you attend the Annual Meeting. Please note, however, that if your shares of record are held by a broker, bank or other nominee and you wish to vote at the Annual Meeting, you must obtain a proxy issued in your name from that record holder.

i

Thank you for your ongoing support and continued interest in the Company. We look forward to seeing you at the Annual Meeting.
