Exhibit 99.1

Natural Alternatives International, Inc. Reports 68% Increase in Second Quarter Pre-Tax Earnings and 25% Net Sales Growth

SAN MARCOS, CALIF, February 9, 2005 /PRNewswire/ —Natural Alternatives International, Inc. (“NAI”) (Nasdaq: NAII), a leading formulator and manufacturer of customized nutritional supplements, today announced net income of $1.6 million or $0.25 per diluted share on net sales of $44.3 million for the six months ended December 31, 2004.

For the first six months of fiscal 2005, net sales increased 31% to $44.3 million from $33.9 million for the comparable period last year. Net sales growth resulted from a 41% increase in contract manufacturing sales. Income before income taxes doubled to $2.4 million from $1.2 million for the comparable period last year. Net income increased to $1.6 million or $0.25 per diluted share compared to $1.1 million or $0.19 per diluted share in the comparable period last year.

Second quarter net sales increased 25% to $21.5 million from $17.2 million for the comparable quarter last year. Net sales growth resulted from a 33% increase in contract manufacturing sales. Income before income taxes increased 68% to $1.0 million from $612,000 in the comparable quarter last year. Net income increased to $785,000 or $0.12 per diluted share from $576,000 or $0.09 per diluted share for the comparable quarter last year.

As of December 31, 2004, NAI had cash and working capital of $4.6 million and $14.9 million, respectively, compared to $7.5 million and $17.5 million, respectively, at June 30, 2004. Cash flow from operating activities for the first six months of fiscal 2005 was $2.5 million. We invested $5.2 million in the expansion of our Vista, California manufacturing facility, which included the acquisition of additional manufacturing equipment. We funded our capital expenditures from available cash on hand. As of December 31, 2004 we had $7.1 million available under our working capital line of credit.

“We completed our 46,000 square-foot production facility expansion in California,” stated CEO Mark LeDoux. “The new 162,000 square-foot facility will help us improve operational efficiency, increase manufacturing capacity and reduce business risk. We are pleased to have been able to fund this investment in our long-term growth exclusively out of cash from operations.”

President Randell Weaver added, “While we effectively managed our selling, general and administrative expenses to improve profitability over the comparable prior period, we incurred regulatory costs of $602,000 in the first six months of fiscal 2005 and we expect to continue to incur increased regulatory and other costs during the remainder of fiscal 2005 related, in part, to the scheduled Therapeutic Goods Administration certification review and planned third quarter introduction of upgraded marketing programs for our direct-to-consumer product lines. We do not expect an immediate return on the regulatory and marketing costs. These increased operating expenses, combined with anticipated relatively steady net sales for the remainder of fiscal 2005, will reduce our net income. We expect to remain profitable at reduced levels for the remainder of fiscal 2005.”
