Check the appropriate box below if the Form 8-K filing is intended to simultaneously satisfy the filing obligation of the registrant under any of the following provisions:

On December 5, 2012, LifeVantage Corporation (the “Company”) issued a press release announcing that it is contacting some of its independent distributors and customers to voluntarily recall and replace certain bottles of its Protandim^® dietary supplement. A copy of the press release is attached as Exhibit 99.1 to this report and is incorporated herein by reference.

The Company is taking this action as a precautionary measure due to the possible inclusion of small metal fragments in its final product. The fragments were originally discovered in batches of turmeric extract, an ingredient in Protandim^® that was purchased from a third party supplier. Upon discovery of the possible contamination, the Company proactively notified the FDA and voluntarily commenced this recall. This voluntary recall only affects certain lots of Protandim^®, which are identified in the press release. Although the final cost of this recall is difficult to ascertain with certainty at this time, the Company estimates that the gross cost could be as high as $7 million before recovery from suppliers and expects the costs to be primarily reflected in the Company’s second fiscal quarter results.

The information furnished in this Item 8.01 and the exhibit hereto shall not be deemed to be “filed” for purposes of Section 18 of the Securities Exchange Act of 1934, as amended (the “Exchange Act”), or otherwise subject to the liabilities of that section, nor shall it be deemed incorporated by reference in any filing under the Securities Act of 1933, as amended, or the Exchange Act, regardless of any general incorporation language in such filing.
