Bests & Worsts Reviews from Amazon

t can be frustrating buying vitamins, since it is difficult to evaluate and compare various brands for effectiveness, and one rarely feels a cause and affect within an hour or two of taking the vitamin, so that there is a clear cause and effect. It seems that one simply takes vitamins over an extended period of time, and one must make a subjective judgement as to how any supplement contributes or affects one health, in context of everything else that they have been ingesting. With a headache, you can judge the effectiveness, as with anti-histamines, pain pills, and the like, but there is no immediate relief that can be judged by a vitamin. I have taken a wide array of vitamins and minerals in strong doses for an extended period of time, and not notice feeling any better. I can stop taking all vitamins and supplements, and can hardly tell any difference in how I feel. how can you really evaluate vitamins? I have read some recent studies that say that there are no objective results that prove the effectiveness of multivitamins, which I find hard to believe, but that is the crux of the problem. I finally discovered a consumer research service called ConsumerLab that evaluates the claims of vitamins and checks for valid claims, and the trustworthiness of ingredients, and then shows the least expensive quality product. What a find. Spoiler Alert: ConsumerLab rated Centrum Silver Multivitamins as being of high quality, and also being one of the top three values of multivitamins on the market. I'll have to go with their research, as I simply can't tell you how various vitamins compare based upon how vitamins make me feel.
