Exhibit 99.1

Natural Alternatives International, Inc.

Announces Second Quarter Results

SAN MARCOS, CALIF, February 14, 2006 /PRNewswire/ —Natural Alternatives International, Inc. (“NAI”) (Nasdaq: NAII), a leading formulator, manufacturer and marketer of customized nutritional supplements, today announced net income of $461,000 or $0.07 per diluted share on net sales of $19.9 million for the second quarter ended December 31, 2005.

Second quarter net sales decreased 8% to $19.9 million from $21.5 million for the comparable quarter last year. The reduction in net sales resulted primarily from a decrease in private label contract manufacturing sales. Income from operations was $843,000 compared to $882,000 in the comparable quarter last year. Net income decreased to $461,000 or $0.07 per diluted share from $785,000 or $0.12 per diluted share for the comparable quarter last year.

As of December 31, 2005, NAI had cash and working capital of $2.2 million and $12.3 million, compared to $1.9 million and $14.4 million at June 30, 2005, respectively. Cash flows from operating activities for the first six months of fiscal 2006 were $3.6 million. An additional $3.8 million of term debt was obtained on December 5, 2005 to fund part of the $5.6 million of net cash used in the recent acquisition of Real Health Laboratories, Inc. (RHL).

CEO Mark LeDoux commented, “During the second quarter we made progress towards the long-term growth and diversification of our revenue, customer base and channels of distribution. Our recent acquisition of Real Health Laboratories provides us with a tremendous opportunity to market our own branded products in new distribution channels. We expect to realize strategic, operational and financial benefits beginning with the integration of certain NAI outsourced activities into RHL’s existing operation and anticipated elimination of certain redundant costs.”

President Randell Weaver added, “During the second quarter, we aggressively reduced costs in response to the net sales decline. We are pleased with our progress related to the integration of the RHL acquisition and do not expect a significant impact on profitability in the third quarter. As previously announced, we received initial purchase orders from two new contract manufacturing customers and have since received additional orders. We expect net sales from these two new customers to exceed $10 million in the remainder of the fiscal year.”
