Has anyone used USANA products?

I used Usana supplements for about a year with ultimately no relief. Initially the Provlavanol helped with the congestion in my ear. In the end I needed to take more and more of the Provlavanol to get some sort of relief and ultimately there was no relief. I introduced the supplements over a period of time as I'm sensitive to medication and supplements. I ended up with tinnitus 24/7 about 10 days after I started taking Gingko Biloba which to this day I still have while previously the tinnitus was sporadic and not bothersome. I can't say if the change in tinnitus was related to starting Gingko I assume it would have happened either way.
