ConsumerLab.comReviews 628

I realize you can't test every product/brand out there. That being said, I seem to be using brands of vitamins/supplements that more often than not, are not included in your testing (I was previously a member, but dropped my membership for this reason. I recently signed up again, but am finding the same situation).

I appreciate the information shared on Consumer Lab and use it before making any supplement purchases. I do wish they were able to test more products in each area and provide updates for those products ranked as a best but are no longer available.

Generally very good experience - I have been a member for about 10 years. The information is sound and scientific. I often recommend their services to friends.

Simply excellent source of information. Facts! Than you

CL has been such a valuable resource over the years, both to keep updated on the latest supplement related research and of course to know which supplements are safe and have accurate labeling.

I always check consumerlab.com before buying any new supplement. Great info.

I've subscribed for as long as ConsumerLab has been in existance. I want to say 20 years? I've used it in teaching librarians how to research for consumer health information and even for medical professionals to do the same. Now I mainly use it to check everything and anything I may consider taking for my own or family and friends' health. Great information and excellent citation and verification processes. I'm very happy.

Excellent in every way. Highly recommended!
Site contains more info than anyone would ask for.
I never buy any vitamins or supplements without running them thru consumerlab.com

In general my experience is looking up whatever information CU Lab presents and it has always been informative and helpful.
I have no experience with any personal questions at time.
You do a good job!

As a physician, I find this a valuable resource. I wish you reviewed more Vitamin World products as they are popular around here.

We sincerely appreciate the depth and thoroughness of your reviews. Cannot think of anything more necessary in this society and time in history.

Good to have facts I can trust- it's the wild west in supplements

After learning the hard way, I've made a point to search your treasure trove of information before purchasing any supplements. This is more important now than ever as fancy packaging with false claims conceal faulty products.

Consumerlab.com is my go-to site for objective information about supplements and their usefulness or lack of usefulness, and for side effects and interactions. Kudos for a unique and comprehensive source of accurate information. The occasional updates that are pushed to my email are much appreciated, as they cause me to re-evaluate and update supplements for my own use.

It helps to know which supplements are what they say they are. Additional information on what works and what doesn't as well as risks or dangers in taking certain supplements is essential.

In light of all the spin, misinformation and bs I'm bombarded with on commercials all day, everyday, I'm secure in the fact, I have a place
Like ConsumerLab, I can go to and get the facts. No biased opinions, no blown out of proportions claims, just the educated truth backed up by
Studies and test trials. Been a member for years and have NO plans to quit.

I rely on Consumer Lab testing and advice. There is too much bad medical information on the internet so it is nice to have a site based on science..

I always look forward to new reviews posted on ConsumerLab. The topics hit current popular interest, but love referencing the website's data on previously reviewed products as well. Thank you for providing reliable information!

When I have a question about food or medication safety, I trust that ConsumerLab will have scientifically-based information.

Great information and detailed explanations. Product comparisons are priceless. Science reviews are excellent.
