It 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 judgement as to how any supplement contributes or affects one health.
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 judge 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, which I find hard to believe, but that is the crux of the problem.
I finally discovered a consumer research service called ConsumberLab 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: ConsumbrLab rated Kirkland CoQ10 a best buy for quality and price. 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
