Exhibit 99.1

Natural Alternatives International, Inc. Reports 36% Net Sales

Increase and Net Income of $0.13 per Diluted Share for the First

Three Months of Fiscal 2005

SAN MARCOS, CALIF, October 25, 2004 /PRNewswire/ —Natural Alternatives International, Inc. (“NAI”) (Nasdaq: NAII), a leading formulator and manufacturer of customized nutritional supplements, today announced net income of $852,000 or $0.13 per diluted share on net sales of $22.7 million for the three months ended September 30, 2004.

First quarter net sales increased 36% to $22.7 million from $16.7 million for the comparable quarter last year. Net sales growth resulted in part from a 50% increase in private label contract manufacturing sales. Income from operations increased by 121% to $1.4 million from $630,000 in the comparable quarter last year. Net income increased to $852,000 or $0.13 per diluted share from $567,000 or $0.09 per diluted share for the comparable quarter last year.

As of September 30, 2004, NAI had cash and working capital of approximately $3.2 million and $16.3 million, respectively, compared to $7.5 million and $17.5 million, respectively, at June 30, 2004. First quarter cash used in operating activities was $1.6 million principally due to compensation payments of $1.6 million under our fiscal 2004 Management Incentive Plan resulting from our growth in earnings in 2004. Additionally, first quarter capital expenditures of $2.6 million resulted from our investment in the expansion of our Vista, California facility and acquisition of additional manufacturing equipment to expand production capacity. We funded our capital expenditures from available cash on hand. As of September 30, 2004 we had $7.6 million available under our working capital line of credit.

“We begin our 25^th year building upon the remarkable financial performance of fiscal 2004. First quarter income from operations improved 16% over the fourth quarter of fiscal 2004,” stated CEO Mark Le Doux. “Our first quarter net sales were in line with our growth plans for fiscal 2005. Building on our reputation of quality products and turnkey services, we are beginning to see brand preference develop in our contract manufacturing business. We look to increase our net sales and expand our customer base, while serving the needs of our valued primary customers who contribute to the foundation of our sustainable growth plans.”

President Randell Weaver commented, “Growth like we experienced in fiscal 2004 requires investment in expansion. We look forward to consolidating our manufacturing activities into our new manufacturing space in our fiscal third quarter. We believe our Vista, California expansion into an additional 46,000 square-foot production facility will meet increased demand and further streamline our manufacturing capabilities. We are pleased that capital expenditures, working capital, total debt and cash used in operations were in line with our growth plans for fiscal 2005.”
