We monitor reviews for authenticity
I originally went to Consumer Lab for supplements actual content vs. stated content and contaminates. Now I look at safe upper limits, what the supplements do or not do, and side effects. Rating other products related to health, like sunscreen, water filters, and PFAS in dental floss are good to know.
An invaluable resource to have at your fingertips plus you get a weekly newsletter with additional updates.

The information on this site is invaluable. I check it for information on every supplement, body care product and some food items (like olive oils) before I purchase. Save buying tainted products, products that have mis-information on their labels, toxic metals, etc. Their TOP PICKS are best info ever.

I refer to ConsumerLab for any and every question I have for nutrition, nutrition supplements, and wellness products! Authoritative, thorough, referenced, and extremely well organized information. In addition to all this valuable information, we then get a product listing tested for strength, purity, dose, cost, etc. to aid us in choosing the appropriate product (and choosing wisely). [The only products I 'ever' choose are those that pass the ConsumerLab testing! [And a final bonus: ConsumerLab will always inform its readers of important updates on everything they report on; so staying up-to-date on the most current information available is made easy.]

GREAT reviews of any supplements you want to take with what they are supposed to do for you…
Which ones actually have the correct amount of what they claim to have…
Which ones cost the least for the best product…
A priceless service.I highly recommend signing on to their service.I believe it may be the best $75 / yr you will spend if you take supplements regularly!

Never failed me all these many years, and I am an astute medical professional. I rely on CL for concise, accurate and timely information, critical in today's environment of misinformation. So glad it's geared to everyone and accessible to all. CL welcomes input/suggestions as well...huge kudos!

Consulting Consumerslab is my first task before I purchase any supplement, as there is no way to tell which is most potent, which are beneficial and which may be harmful without testing. The discussions, and reviews of recent studies are terrific. Honestly, I would be lost without my daily ConsumersLab email.
Thank you so much for your wonderful review! We're thrilled to hear that Consulting ConsumersLab has become an essential part of your supplement purchasing routine. Ensuring potency, safety, and effectiveness is our top priority, and we're glad to hear that our discussions, reviews, and recent study analyses have been helpful for you.
It is a good resource to start one's search of specific products. However, there are MANY cleaner, less toxic products out there in at least some categories (for example smaller businesses) AND where on earth is "Guthrie's Corner"...listed on fb page as the address?. The state should at least be given for transparency purposes. EWG's app for products I have heard is $$$$ motivated. Would love to see these apps reviewed.
When reading about the various water filtering products approx. One year ago I requested that they also test the Clearly Filtered filters. They responded by reciting the Clearly Filtered manufacturer's published data rather than subjecting it to the same tests as the other products mentions. This month they, once again, tested several of the water filters on the market. In their statement they mentioned that several subscribers had requested that they test the Clearly Filtered filters. They once again responded by quoting the company's published data (that we are all capable of reading on our own). This still leaves the conclusion up to the subscribers to determine, which we can do without subscribing.
I sincerely appreciate the research, information, education and care that Consumer Lab provides its clients. I base my purchases on the reviews and ratings of Consumer Lab. There are too many products on the market that are not what they advertise, contain fillers, inferior or unsafe ingredients. Thank you for your research!
Thank you for your kind words and trust in Consumer Lab, NAT. We're dedicated to providing accurate information and helping you make informed choices. Your support means a lot to us!
I have been a subscriber for a number of years, and I am always impressed by both the depth and breath at which ConsumerLab.com reports out its findings on various products, especailly supplements. I know of no other source for this type of information. I also appreciate the opporutnity to recommend supplements for testing, as well as the direct contact with staff as on one occasion the report on NAD and its possible cancer implications.

First place I look for objective reviews on all things nutritional.
Given that dietary supplements are totally unregulated, having access to ConsumerLab reviews bridges that gap quite nicely while also providing additional value with deep dives into existing scientific evidence for the efficacy of each supplement reviewed.
Consumer Labs is my first stop when researching all supplements and any foodstuff. I base all my choices (and recommendations to family and friends) on their reviews. I am a very healthy, fit 70+ year old who trusts this resource. It's worth the fee to have all their research available to me. Keep up the good work!
Very useful unbiased reports on their product tests and the findings. Knowing which supplement makers to trust is of crucial importance to me. I also like their informative newsletters about the latest research pertaining to various substances usually available as supplements. Can hardly imagine being without Consumer Lab as an aid now.
Thank you so much for taking the time to leave such a thoughtful and positive review! We greatly appreciate your kind words and are thrilled to hear that Consumer Lab has been a valuable resource for you.

Each review is very comprehensive and thorough. I use it regularly to help select supplements. Sometimes I wish more brands would be on the list.
Am grateful each time I access the ConsumerLab site. It provides me with detailed, accurate information on the various supplements I choose to take. I am always surprised by the number of companies that do not measure up to their own advertising! Thanks for "having my back" when selecting supplements…I count on your knowledge & integrity.

I sometimes see items on you prime choice picks that are not easy to find or do not exist. Case in point, anything made by Rexall. I finally found that Rexall is through the same company that owns Dollar Store. But I could not purchase your 1st choice. Can you include a link to purchase items like LabDoor does?
Please test more choices of each product. Looking at Amazon can help you narrow your choices if you look at the number of purchases of particular items.
Answer: Hi Denise, We have actually covered this topic on our website https://www.consumerlab.com/answers/does-prevagen-really-improve-memory/prevagen-memory/.
Answer: Hi - We don't charge every month; just a single charge for a 1-year or 2-year subscription as noted on the page where you joined. We show the calculated cost per month for reference, so you can see that the 2-year subscription is less expensive. If you would like to cancel, please email [email protected] with your name and email and we will process your request (typically within 1-2 business days).
Answer: Hi Frank - I believe you are referring to the review of ConsumerLab from 2004 Journal of the Medical Library Association. Our content and website have continued to expanded annually and membership has increased over those 16 years. The current 1-year membership is $47.40, or $78 for 2-years (an 18% savings off the 1-year rate).
Answer: Hi Bob - As a subscriber, you are entitled to print out a copy of the report (or any pages thereof) for your personal use. However, we don't permit copying or distributing our content, which is proprietary.
Answer: Not yet, but we may next year. We have written about PQQ: https://www.consumerlab.com/answers/is-pqq-similar-to-coq10/what_is_PQQ/
Answer: Hi Theresa - As noted on our site, we permit subscribers to print a copy of our reports for their personal use, but we do not permit not copying or downloads. If you were somehow able to download content from our site, it is quite possible that it would only work while your membership was current.
Answer: There is no single best supplement or brand. It's best to focus on the type of supplement you are looking for, e.g., multivitamin, fish oil, probiotic, herbal) and read our Product Review for that specific category and see which product is our Top Pick for that category. Here is a list of our current reports: https://www.consumerlab.com/results/
Answer: Yes, we recently published a new report on turmeric and curcumin supplements as well as turmeric spice (ground root powders) at https://www.consumerlab.com/reviews/turmeric-curcumin-supplements-spice-review/turmeric/
Answer: Hi Barbara - You can give a gift membership to ConsumerLab.com from this page: https://www.consumerlab.com/giftcerts/. We have a link to this at the bottom of every page, but the font is a bit small. Hope that helps.
