I bought 15 bottles of USANA Active Calcium for my parents from amozon.com, 3rd party vendor, found 4 of them were labeled as "Imported by USANA xxx SINGAPORE LTD". It's obviously products that should be exported to Singapore. And their Supplement Facts are different from those of US products, at least 3 elements were dismissed. In other words, it's obviously inferior than the US products. Is it legal to sell medicine like this in California? Is it a fraud to sell such 4 inferior bottles together with the rest 11 bottles?
