(Logo: http://photos.prnewswire.com/prnh/20130319/PH79245LOGO) The company reported net sales of $2.5 million for the quarter ended March 31, 2013, compared with $1.1 million for the same period in 2012. The increase of 127% was attributable exclusively to increased Anatabloc® sales volume. The company also reported positive gross profits of $1.1 million for first-quarter 2013, compared to a gross profit of $0.4 million for the same period in 2012. The Company has reported increased net sales and positive gross profits in each of the last five quarters.The net loss for first-quarter 2013 was $(8.2) million compared with a $(5.2) million net loss for the same period in 2012. The increased loss for the first quarter was primarily attributable to increases in sales and marketing costs, legal expenses, and research and development costs. Sales and marketing costs increased as the company expanded promotion of its Anatabloc® dietary supplement product. As reflected in the 10-Q Report, the Company expects that sales and marketing expenses will trend lower in the near-term as sales and marketing efforts related to Anatabloc® level out in 2013. Legal fees increased in connection with the previously reported ongoing investigations and class action lawsuits. As discussed in the 10-Q Report, the Company anticipates increased costs in this area in 2013. Research and development costs increased in the first quarter as the Company continued to finalize reports on two clinical studies and continued work on its Rosacea clinical trial, which reached full enrollment during the first quarter 2013. As reported in the 10-Q Report, the Company expects that its R&D costs will trend lower in the near-term as work is finalized on the CRP and Hashimoto's autoimmune thyroiditis clinical studies.

Specifically, Anatabloc® was recognized by GNC as the Wellness Winner in the category of Best Product Innovation for 2012.
