First and foremost, Shaklee vitamins are an MLM product. This means when you pay for them, you not only pay for the actual product, and associated advertising and development costs like you do with regular vitamins. But you also pay for all the bonuses that are involved in multi level marketing. And that is a lot of extra money per product.
Vitamins are not unique substances. Some of the delivery techniques to get vitamins absorbed in a useful way are, but the standard of non MLM vitamins is of such a high level, that I do not believe there is an advantage to a particular company's patented delivery system if it also involves huge additional costs related to an MLM structure.
Non MLM vitamin companies also develop and research their products so that they can stay on top and relevant in a very competitive marketplace. I have found some excellent products on the shelves of regular health shops (and their online equivalents), and they are very well priced. Health should not cost any more than it needs to.
Another thing to consider is that when scientific researchers such as Linus Pauling have done their studies that validate certain supplements with regards health benefits, they are using regular supplements - not MLM vitamins. And if it is good for the patients in those (successful) studies...
Bottom line - you don't need to pay the premium of distributors fees to get great vitamins. Check out Consumer Lab for quality control testing of popular supplements available in the US.
