This vitamin smells so horrific, it is impossible to take. I tried holding my breath and taking it. Didn't work. You would not believe how terrible this smells and tastes. I thought maybe it's because they are closed up in the bottle. I took the lid off and no lie, they stunk up the room. I called Life Extension because I've bought their products for years. I even get their monthly magazine. I told the rep , I've been buying their products for over ten years. The representative told me they only refund products, if you buy direct from them. I told her “if you don't stand by your product, that's fine. I'll just take my business elsewhere and never buy them, again.” Then I hung up. The company did try to reach me, but I didn't answer. If they wouldn't help me the first time, don't bother after you loose my business. Take care of loyal customers when you have them. Once we're gone, we're gone. I've started buying Gflow and love what I bought, so far and just ordered a second product from them.
