Tod Cooperman looks and sounds like a good man with principles, and a keen eye for rigorous science. I have been reading and listening to him for many years. Could any company or billionaire shyster offer him a chalet in France, or millions for a sick relative's care any day of the week -- in return for a false positive review? Yup. We would see it on his face though. He has been making the world better for a long time. Keep that integrity, Dr. Tod and thank you!!

Thank you for your very kind words. When I started ConsumerLab.com in 1999 my goal was to provide the kind of information about supplements (and, eventually, foods), that I would want to provide to my own mother -- and that has been a guiding principle ever since. I'm happy to say that she is still using ConsumerLab (and still suggesting edits every now and then!)

I have been subscribing to consumer lab for years and I truly appreciate their testing and scientific reviews. In many cases, I decided against a supplement because their thorough analysis demonstrated no advantage (or a questionable one). I rely on consumer lab when making lots of food and supplement decisions.

The site is an invaluable source of information about and testing of consumer foods and supplements that we rely on in our purchasing decisions. We also think that this transparency helps to police the marketplace to some degree, cutting through the hype.

I love the serious science analysis and often share info with my residents, med students and patients. And i appreciate the site owners refusal to refuse to back away from their data driven findings when threatened by a vendor.

I've been a member of ConsumerLab for years and won't buy a supplement or health food without checking for safe & effective products. Sometimes I DON'T buy, if the supplement itself wouldn't be good for me depending on my particular situation. I've learned so much about health in general from this site. And everything discussed is backed up with evidence & citations, down to the dosage recommendations & warnings. I tell everyone about Consumer Lab. And they don't pay me to do so :-), in fact, the subscription fee is very reasonable considering everything you get.

Thank you so much for this. It truly means a lot to hear that ConsumerLab has become such a trusted part of your decision-making. We’re especially glad that the information has helped you not only choose products more confidently, but also avoid products that may not be right for your particular situation. Our team works hard to provide evidence-based information, practical guidance, and clear warnings people can actually use, so hearing this kind of feedback is incredibly rewarding. We also really appreciate you telling others about ConsumerLab. That kind of support means a great deal to us. Thank you again for being a longtime member.
