Exhibit 99.1

Natural Alternatives International, Inc.

Announces First Quarter Results

SAN MARCOS, CALIF, October 24, 2005 /PRNewswire/ —Natural Alternatives International, Inc. (“NAI”) (Nasdaq: NAII), a leading formulator and manufacturer of customized nutritional supplements, today announced net income of $412,000 or $0.06 per diluted share on net sales of $21.7 million for the three months ended September 30, 2005.

First quarter net sales decreased 4% to $21.7 million from $22.7 million for the comparable quarter last year. The reduction in net sales resulted primarily from the decrease in private label contract manufacturing sales. Income from operations decreased to $678,000 from $1.4 million in the comparable quarter last year. Net income decreased to $412,000 or $0.06 per diluted share from $852,000 or $0.13 per diluted share for the comparable quarter last year.

As of September 30, 2005, NAI had cash and working capital of $5.6 million and $15.3 million compared to $1.9 million and $14.4 million at June 30, 2005, respectively. Cash flows from operating activities for the first quarter were $3.8 million.

President Randell Weaver commented, “An increase in revenue from our largest customer was offset by a reduction in revenue from our second largest and other contract manufacturing customers. As we anticipate the decline in revenue to continue in the second quarter of fiscal 2006, we are responding appropriately to reduce our cost structure and remain profitable. We continue to identify and evaluate acquisition opportunities that could increase product lines, expand distribution channels or enhance manufacturing capabilities.”

CEO Mark LeDoux added, “We have made a considerable investment in our recent facility expansion and TGA recertification in an effort to develop new relationships with large, quality

oriented contract manufacturing customers. We believe this strategy is beginning to be rewarded. We have received initial purchase orders from two new customers who are leaders in the direct sales marketing channel. We expect to fill the initial orders in our fiscal third and fourth quarters and are optimistic our relationships with these new customers will continue to grow.”
