I've tried many multi vitamins or vitamins in general and found Nature made multi vitamin to be a great find. I like that it is in a gelform which makes it easy to take. It makes you feel refreshed and energized but not overly energetic. I purchase the vitamins from GNC a local health store but find it hard to locate at a regular store like the grocery store. I personally didn't have any adverse side effects while taking them and was able to take them with my other medications with no problems. I would recommend Nature Made to fulfill all your vitamin needs!
