It's hard to judge the effects, I can only trust them. I may start to feel a little better after about two weeks, but that may be a paid effect, hard to say. Anyway, the packaging is great, the box is practical,after consuming it will definitely be useful at home for other things. The smell or unpleasant odor (which some complain about) did not take place. It does not smell any worse,than other vitamins, or medicines. The tablets "slide" well so can be swallowed easily if necessary without swallowing. So far so good.
