USANA Health Sciences Inc. launched its seasonal Vitamin D supplement. The supplement will be available every year from November to March, the months when many people do not get enough vitamin D. Vitamin D is essential to bone mineralization and growth and plays an important role in the maintenance of muscle strength and coordination. Vitamin D also supports cardiovascular health and promotes balanced immune function. The current recommendation of 400IU of vitamin D per day may not be enough to prevent vitamin D deficiency during the winter months. USANA's supplement has 2000IU of vitamin D per tablet.

USANA Health Sciences Inc. announced that a third-party clinical study at Australian Catholic University (ACU National) found that use of USANA's Active Calcium(TM) Chewable supplement improves bone health in young girls. The double-blind, placebo-controlled study involved 20 pairs of identical twin girls, ages 9-12 years old, who were randomly assigned to receive USANA's Active Calcium Chewable or a matching placebo. The results of the study found that after six months of supplementation, Active Calcium Chewable improved measures of bone mineral content, bone mineral density, and bone strength in these girls. Results of the ACU National study are particularly significant, because young women accumulate bone mass most rapidly during adolescence, and ideal skeletal development can only be achieved when dietary intakes of calcium, vitamin D, and magnesium are optimal during this period.

USANA Health Sciences Inc. reported capital expenditure of about $1 million for the third quarter of 2009. Capital expenditures were just under $3 million for the first nine months of 2009. The company expects capital expenditures to be less than $5 million for the year 2009.
