If you know how to tell the difference between natural and synthetic vitamin, you will realize that Nutrilite Double X is full of cheap synthetic vitamins. Overall, it just another average multivitamin but more expensive. Double X health claims are very misleading. Most, if not all of its vitamins are not extracted from organic sources and its minerals are not chelated minerals. Chelated minerals are the best minerals but are more expensive which is why most vitamin manufacturers are scare of using them.

I took Double X for a month (three tablets daily) and felt a noticeable increase in energy but not much. I also experienced side effects such as stomachaches, especially when taking it on an empty stomach.
