Consumerlab provides me with the TRUTH (pros/cons) on products I purchase. I trust this site wholeheartedly. Please keep up the great work. It is so very comforting to have Consumerlab to protect me, my husband, and the whole family with HONEST information.

I love my ConsumerLab membership. I don't buy anything anymore without searching the best from your findings.
Member Since 2017 is my go-to place to evaluate dietary supplements. It's an independent organization staffed by good people providing good advice for anyone taking supplements.

I have used Consumerlab's independent test information to help select the best supplements such as calcium, magnesium, Co-enzyme Q-10, and others. They have found contaminants in common supplements and in foods like cocoa and canned tuna. You really have to do your homework before using or recommending dietary supplements and vitamins.

My doctor recommended your site a few years ago, and I feel the modest membership fee is more than recompensed with the excellent vitamin and supplement information. Those of us who "take charge of their health" need this information.I never take any vitamin or supplement with out researching its considered value and any potential negative side effects.
Member Since 2014
I've already switched three supplements simply based on your independent and objective testing. I believe supplements can have a useful role in health, but only if (i) there is some scientific evidence validating their claims; and (ii) the products contain what their labels claim. Thanks so much for the good work you do in providing this information. This member really appreciates it!

I want to thank you personally for the work that you do -- I have subscribed to ConsumerLab for many years, and feel that it is a vital service to our patients; we also used it in my Integrative Medicine fellowship with Dr. Weil at the University of Arizona.

Making sense out of health supplements, ConsumerLab consistently impresses. I'm a repeat subscriber.

"As a health & fitness consultant and author, I love and recommend your subscription in all my national and local seminars, lectures and presentations, and have for years. When I speak at seminars the audience is always blown away when I tell them about the loose regulation of supplements, and then tell I them about's findings. You guys are amazing! Thank you for everything you do!"
Member Since 2005 is my 'go to' source for accurate and unbiased supplement information. When clients ask me about supplements, I check CL for the most up-to-date information. CL helps me assist my clients in making sound, scientifically based and knowledgeable decisions about supplements and is a beacon of truth in the tsunami of nutrition misinformation.

Just wanted to say thanks. I have referred many people to your website and encouraged them to become paid subscribers because I truly think you are making a concerted effort to educate consumers. I want to read about the clinical studies and decide for myself whether or not to take a particular supplement.So you know, I will not take a health supplement unless I've seen your product review of it!Keep up the marvelous work...

As an adjunct professor at FIU teaching exercise and nutrition, I truly embrace what has done to educate and look out for the consumer's health on a topic so misunderstood and monetized.
