USANA health sciences is a MLM (Multi-level Marketing) company which is often associated with a pyramid scam. They sell vitamins and health supplements; or rather their distributors sell them. The people at the top simply collect from the profit flow, which stretches upwards. The question of the USANA scam is a complicated one.
First, the products that USANA sells are very expensive. They claim top ratings among various third-party sources, but the question of whether the price is worth the punch is still a valid one. In addition, the way that people make money through MLM and USANA is not mainly through the distribution of the products, but through recruitment. Each distributor is required to buy a set amount of products, the price of which ranges in the hundreds of dollars, and they must buy these products every month. Executives claim this is because they only wish people who use and believe in their products to sell them, but it is this policy, which allows the most money to be made.
Strictly speaking, USANA may be unethical, but it is not a scam. The USANA scams result from aggressive distributors trying to trick new recruits into joining in order to increase their own profits, even if they know these new members do not have what it takes to succeed. This creates an USANA pyramid structure whereby only those at the top make good money, those below making steadily less the closer you get to the bottom. Those at the bottom, who are recycled quickly, actually tend to lose money.
Looking at any USANA product review reveals mixed feeling between the product and the means used to sell it. People generally think the product is good, though over-priced. Reviews of their recruiting methods are incredibly negative, however, most of them expressing anger over the way they were treated by those who tried to recruit them, whether successful or not. Whether there is an actual USANA scam or not, anyone wishing to look into this MLM scheme should be very cautious about it.
