Natural Alternatives International, Inc.

Announces Fiscal 2008 Results

SAN MARCOS, CALIF, September 22, 2008 /PRNewswire/ —Natural Alternatives International, Inc. (“NAI”) (Nasdaq: NAII), a leading formulator, manufacturer and marketer of customized nutritional supplements, today announced a net loss of $371,000 or $0.05 per share for fiscal year 2008. These results included income from continuing operations of $912,000 or $0.13 per diluted share offset by a $1.3 million loss from discontinued operations or $0.18 per share. Net sales from continuing operations decreased by $4.8 million or 5.6% from $86.6 million in fiscal 2007 to $81.8 million in fiscal 2008.

For the fourth quarter of fiscal 2008 revenues from continuing operations increased slightly to $21.5 million from $21.4 million in the prior year period. This increase was primarily due to increased private label contract manufacturing sales partially offset by a decrease in our Dr. Cherry Pathway to Healing® product line sales. The net loss in the fourth quarter of fiscal 2008 was $168,000 or $0.02 per share compared to a net loss of $6.6 million or $0.96 per share in the prior year. The net loss in fiscal 2007 was primarily attributable to the $7.0 million non-cash goodwill impairment charge related to legacy RHL that was discontinued in the fourth quarter of fiscal 2008.

As of June 30, 2008, NAI had cash and working capital of $3.5 million and $18.1 million, respectively, compared to $4.1 million and $16.2 million, respectively, in the prior year. As of June 30, 2008, we had $7.5 million available under our working capital line of credit.

President Randell Weaver stated, “During the fourth quarter of fiscal 2008 in an effort to enhance stockholder value, improve working capital and enable us to focus on our core contract manufacturing businesses, we elected to narrow our branded products

focus and portfolio and developed a plan to sell some of our branded products assets. In addition, we have taken steps to significantly reduce our operating costs. While we expect our continuing operations to be profitable, we also expect to incur losses from discontinued operations in the first quarter of fiscal 2009 which are likely to exceed profits from continuing operations. Going forward, we believe focusing on our core private label contract manufacturing operations will significantly improve our overall profitability and allow us to better pursue our growth initiatives.”

CEO Mark LeDoux added, “Our balance sheet remains strong, and we believe the sale of selected assets will further strengthen our balance sheet. Obviously, in today’s economic climate, there are significant challenges. Our strong balance sheet and international scope should position us to meet these challenges effectively. We believe the steps we have taken will enable us to effectively capitalize on opportunities as we move forward.”
