Best Nutritional Supplements Brands

How do you know what brand of herbal supplements is the best and most credible?
I spend a lot of money to buy a lot of Nutritional Supplements and herbs, but lately I wonder what can really know what the supplements contain ingredients in amounts that say say, and are manufactured to quality standards, etc. Because they are unregulated, how can we know for sure. Are there brands that are often tested by independent laboratories and how do we know that society is not only supplement the return from the laboratory to give a passing grade? I'm obsessed with it, but do not know how find reliable information about it. Can anyone help me? Thank you.
Good question, because these products are essentially unregulated. Http: / / www.cfsan.fda.gov/ ~ Dms / DS-savvy.html are sometimes contaminated. Here is a complete list of warnings and recalls from the FDA: http://www.cfsan.fda.gov/ ~ dms / DS-warn.html This site intends to review the supplements, but registration is required. The NIH has reviewed the site, but mentioned the accuracy of the tests. http://www.consumerlab.com/ http://www.pubmedcentral.nih.gov/articlerender.fcgi?artid=521528 Consumer Reports evaluates some supplements, but I think this site also requires a subscription: http://www.consumerreports.org/cro/health-fitness/drug-supplement-index.htm I would be interested to know about third-party testing.
