After taking Nature's Code 90 Day Vitamin System with CoQ10 for almost four months, I decided that it was not the multivitamin system for me. When I first started taking the vitamins I noticed that I had the worst nauseated feelings that I had ever had. Also, for about the first month of taking the vitamin, I would get sick to my stomach. I did however, overcome this side effect after getting used to the vitamins. I don't feel that Nature's Code 90 Day Vitamin System with CoQ10 did anything to help with my dietary needs. I feel that this vitamin system is overrated and overpriced. Another thing that I didn't like was the size of the pills, they seemed to be very large and hard to swallow as well as they also left an aftertaste that was really hard to overcome. I feel that there are alot more vitamins on the market that will give you much better results and don't cost half as much as the Nature's Code 90 Day Vitamin System. I would not recommend these vitamins to anyone.
