I have used Consumer Labs for several years now and I find it to be worth the cost of membership. Although some testing is done on natural sourced supplements (as opposed to synthetic)I would like to see more as those are the type that I use.
I bought it a couple of months ago as it was top rated it now shows there's a new formula. I wish I could have a rating on the current one as I use it every day and have a large supply on hand.
I depend on ConsumerLab for unbiased evaluation of OTC dietary supplements. The few supplements I use are always CL's top picks. CL saves me time and money. I recommend CL to everyone I know. Thank you, CL!
Core facts should be summarized. If someone wants to check the research, they can go further into the subject, but we should not have to fight through so much information to get to the point, good or bad.

Thank you for your thoughtful feedback, Dr. Tedone. We appreciate you taking the time to share it. Your point about making the core facts easier to get to is well taken, and we will share your comments with our team as we continue working to improve clarity and usability.
This is the only source I trust for information on vitamins a supplements since it is the only resource that tests them
Thank you so much for your trust and kind words. We’re honored to be your go-to source for information on vitamins and supplements. Our independent testing is central to our mission, and it means a lot to know that this is what makes ConsumerLab valuable to you. We truly appreciate your support.
Excellent experience in receiving trustworthy info on safety and performance of consumer goods
Thank you for your kind feedback. We’re so glad to hear you’ve had an excellent experience and find our information trustworthy. Providing reliable insights on safety and performance is at the heart of what we do, and we truly appreciate your support.
My experience with ConsumerLab has been noteworthy. ConsumerLab is my go to source when it comes to supplements and products that I am contemplating purchasing. Before purchasing I check to see if a particular product has been tested by ConsumerLab, if not I check to see what products are recommended. I am grateful that ConsumerLab provides this service so that I am not ignorant in regard to products that do not live up to the hype or claims of the manufacturer.
ConsumerLab provides a much needed service to consumers during times of advertising overload.
Thank you so much for taking the time to share this. We’re really glad ConsumerLab is your go-to resource when you’re deciding what supplements and products to buy. Helping people avoid products that don’t live up to the hype, and feel confident about what they choose, is exactly why we do what we do. We truly appreciate your support and are grateful to have you as part of ConsumerLab.
I use your site to determine what supplements are the best ones to buy and I appreciate that greatly. However, several times when I have sent queries about something I have received no response.
Very useful information - just wish you covered more brands
The reviews and details are very informative and useful.
The number of products reviewed in a specific category sometimes seems like to small of a sampling.
On 12/23/25 I submitted a question and there was no response.
A lot of us buy one item and never buy that item again, so we don't have any experience with it. It's nice to have a website where someone else has done all the legwork and research, and we can make an educated choice.
Thank you for your comment. Because many products are one-time purchases, it helps to have independent research available. That’s exactly what we aim to provide.
Consumer Labs is such an important part of my life. The reports have helped my health by explaining lots of topics that relate to supplements, foods, and my own particular health problems. There is information I get here that I wouldn't find anywhere else and wouldn't even know to look for.
Thank you for sharing this. It means a lot to hear ConsumerLab has been genuinely helpful to your health and that the reports have helped connect the dots between supplements, foods, and your specific concerns. We work hard to provide practical information you can’t easily find elsewhere, and we really appreciate your support.
I have been a member of CL for many years and refer to it's reports before buying any supplement. I even use CL when re-ordering items to see if CL has updated reports. CL allows me to buy with confidence, knowing they have done the due diligence for me. CL is an invaluable resource as far as I'm concerned and I wouldn't be without it.
Thank you, Haley, for your support and thoughtful feedback. It’s truly rewarding to know our reports help you. We look forward to continuing to support you with accurate and trustworthy information.
Gives relevant information about the products I use
Thank you, Caroline, for your review. We appreciate your support.
A subscription to ConsumerLab is one of the best values going if you care about reliable, detailed information and reviews of nutritional supplements. The internet is chock full of nonsense and stuffed with utter crap about vitamin, mineral and nutritional products, and ConsumerLab is the best place to find long-form explanations, product reviews and a distillation of quality research. If you buy these products, you really should understand if they "work", how they "work", and where to put your money (and when to run away!). I recommend it strongly!
There were so many products I was buying that were not worth a toot and I did not even know it until I subscribed to Consumerlabs. Attention to detail and updates with new announcements about products are normal whether postive or negative. I did not know how flying blind I was until I started reading Consumerlab.
I love that I can decide the best products to purchase.
Thank you, we’re glad ConsumerLab helps you feel confident choosing the best products to buy.
I have been subscribing for the past few years. The research reports are very useful to me and guide my use of supplements.Please keep them up! I only wish that ConsumerLab would include reviews of supplements by Natural Grocers (formerly Vitamin Cottage). This is a very important provider throughout Colorado and other western states. Very often, I see Consumer Lab focusing on companies that I am familiar with from living on the East Coast, which are not widely used here. I would appreciate better regional balance.
Thank you for being a member and for the thoughtful feedback. I’m glad the reports have been useful and have helped guide your supplement choices.
We also appreciate the suggestion about Natural Grocers (formerly Vitamin Cottage). That’s helpful context, and I understand what you mean about wanting better regional balance in the brands we cover. I’m sharing your request with our review team as we plan future product selections, and we’ll keep it in mind as we look to include retailers and store brands that are more widely used in the western states.
I've been taking supplements for over 50 years based on the philosophy that " it couldn't hurt",,,, because there was no independent laboratory testing if what manufacturers said was in the supplements REALLY WAS in those supplements. ConsumerLab.com is the answer to "faith-based" nutrition. Thank you for providing a much needed service for a very fair price!
Thank you for sharing this. Independent testing is exactly why ConsumerLab exists, so people don’t have to rely on “faith” when it comes to what’s actually in a product. We really appreciate your support, and we’re glad you feel the membership is a fair value.
I consistently follow ConsumerLab reports and look up products on CL to help me choose what to purchase or use.
Thank you for sharing that. We’re really glad ConsumerLab helps you narrow down what to buy and feel confident in what you’re using. We appreciate your support.
