No I havent been to them but why would you want to take so many supplements? If you eat regular food on a daily basis there is no reason to take much more than a regular multi-vitamin. No special tablet needed, just a centrum or one-a-day or even store brand tablets.
It is a total waste of money to use these specialty supplements, if you need a more powerful vitamin, you family doc will advise you on a regimen and they will be likly to prescribe a vitamin supplement.
Selling vitamins is a big business that plays on the ignorance of the public and they can make you sick if you are not already because the mega-quantities in the garbage they are trying to sell. Most of the time the companies don't even care if they sell vitamins because their major goal is to sell franchise ownership with the expectation that you would be able to get rich by getting more of your friends and family to buy their own business selling vitamins.
I personally recommend that you go to c.V.S. And buy the store brand multi-vitamin and use it to supplement your diet, then you need to develop a good meal plan to ensure you are getting the necessary vitamins from food. Food is the very best way to achieve a good store of the vitamins and minerals you need, supplementation is just that.... A supplement to your already healthy diet regeim not your only source of good health.
Good luck;
