Update: I just contacted a pharmaceutical company that produces their own brand of supplements, AND has contracts to supply major drug store brands as well. They told me that you have to read the product carefully, some have slightly different concentrations in certain vitamins and supplements. If it is a single item supplement, then make sure it is ***exactly*** the same. The manufacturing process, the source material is all the same. The difference in price is purely marketing, plain and simple. I asked him that point blank, on two separate occasions in the conversation and he confirmed it twice, and even told me to buy the cheaper store brand name if they are exactly the same.
He also said that DIN numbers may be part of the vitamin and supplement industry in the future and that is a good way to make sure you are comparing apples with apples, etc...
One other thing, a major drug company that produces a very popular acetominophen cleary states on their packaging that they do not manufacture and sell to store brands.
Confession: I have bought store brands over name brands and have done so for pain relievers and one a day vitamins for myself, even thought there is enough anecdotal evidence and heresay to suggest that they are not as good and at the same time just as good. But then again, as mlgable says, you have to be working inside the manufacturing plant to really know the difference. |
