We monitor reviews for authenticity
I love the information that you guys are providing. I trust you which is amazing in this world of inflated and mis-information. I have been a supplement user since 1976. Thanks so much.
I just wanted to say how thankful I am for your organization. You guys make it possible for us (consumers) to cut though all of the marketing hoopla and make educated -and safe- purchase decisions.
Keep up the awesome work!
Although product tests and reviews may be of value, I get flooded, indeed inundated by endless unnecessary reports. Several attempts to unsubscribes were futile and couldn't find on the website how to cancel membership.
Oftentimes while reading ConsumerLab report, I feel that I'm reading from a Pharmaceutical magazine. Example... saying that Turmeric caused one person to be hospitalized with high liver enzymes without saying that the person was on many medication and with many health issues, is being deceitful. There is so many more examples especially on the products known to work well enough to possibly replace pharmaceutical drugs. Beware.
No, ConsumerLab is not associated with Pharma. We are independent and report both "good" and "bad" news regarding dietary supplements, including potential safety concerns.
I read the peer-reviewed scientific literature whenever I need information on a variety of topics (Google Scholar is a great resource), but it is a time-consuming practice. ConsumerLab does such a superb job summarizing research findings on the topics they cover that I don't feel the need to read the original journal articles myself, which frees up time to focus my own efforts elsewhere. I've subscribed to ConsumerLab for years and am consistently impressed with the quality, reliability, and breadth of the information they provide. Highly recommended.
Thank you for that nice review, Ann. We're glad that you appreciate our work. Thanks for your support.
They are giving me preliminary access to the types of tests and their results for a few different supplements. This will help me to decide if I'd like to be a member.
I reviewed this website thoroughly. There is so much to see and experience when it comes to medical knowledge and the type of medicines that you would not think of researching. You can receive a free subscription to their emails but if you want more in depth information, you have to pay. I'll do just fine with Google.
If you sign up for a free trial they will put the funds for a full membership on an authorization hold in your account wether you are using a credit or debit card. The website says the funds will be on hold for 5 days (the length of the trial) even if you cancel before those 5 days are up.
Here it is day 6 for me, I cancelled the trial on day 2 or 3, and the funds haven't been released by today day 6 so I called in. I was told at first it would take 7 days for my bank or card company to release the funds.
I told them no, I specifically used my PayPal debit card for this transaction because they release funds in hours not days. This has been tested by me on multiple occasions, so yes I know it to be true.
They asked when my trial ended, and I told them when I cancelled it. I was told 5 days after I signed up was when it ended even if I cancelled the "free trial" before then. I was then told that if you cancel your trial they would put a note in your account so you won't be charged at the end of the 5 days. If you need their services go for it I guess. I needed information on one thing and their top picks were discontinued, so I ended my membership as it didn't help me. So thanks for nothing but a headache I guess.
**My funds for the trial have now been released. So I guess it's just important that you know the information I've left above. The trial last a full 5 days even if you cancel bwfore those 5 days are up and they hold your funds ($42) for a full 5 days even if you cancel. In my case it was longer**
This review of how a free trial works is not accurate, so I'd like to clarify. If one takes a free 5-day trial, it is correct that a credit card is needed and the amount of a membership is "held" (but not charged) during the trial. If a person opts to cancel the trial and not have it turn into a membership, the funds that were held are immediately released by us -- the same day. The confusion this person had resulted from the fact that card companies and their banks often take several days to process this release, so it can take a while before the funds appear to be released. In fact, PayPal explains this on their website, noting that it can take "3 to 30" days. We explained this to the person who wrote this comment. We are glad that she added a note that her funds were released, but it would have been best if she explained the process correctly and that the cause of the delay was not ours.
I have been a subscriber now for several years and look forward to the updates and latest info on nutritional supplements. Very pleased!
Thanks William. We're glad that you are enjoying your ConsumerLab membership!
BAIT AND HOOK. BEWARE. When you go to their webpage for product comparison you have to agree to receive there newsletter which is sent out twice a week, they then send you to another page where you have to sign up for a PAID membership before they will send the information out. To me this is deceptive and they should inform you up front that you MUST have the paid membership to receive any information. I would have never agreed to receive the newsletters if I had known before hand that I would have to sign up for a paid subscription.
The representative that I spoke with was warm, informative and quickly resolved the reason for my inquire.
Thank you that nice feedback, Lewis!
I have been a member of consumerlab for almost a year. I like that they actually test the products for what they claim to provide. I find it very helpful.
We're glad that you are enjoying your membership to ConsumerLab, Jennifer. Thanks for letting us know.
I'm a scientist and tend to maintain a healthy skepticism of supplements--especially those that make overly strong claims. But there are a few that my doctors have directed me to take. In addition, I have a couple of health issues that conventional medicine hasn't yet been completely successful in treating. ConsumerLab provides an excellent summary of the research available for a number of common supplements. They also point out potential interactions and cautions for people with certain conditions. I appreciate the comparisons of common brands so that I can make sure to get what I'm paying for and also choose the most economical product.
To be honest, I had planned to look up as many supplements and I could during the free 5-day trial and then cancel, but I'm finding it too useful!
We're glad to have you as a member, Lisa! Thanks for your review. You can always feel free, as can any member, to shoot us suggestions and questions that we might answer in our CL Answers section.
I know this review may look confusing. Explanation: I found their reviews confusing, as in, "One study found this; another found that, and so on and so forth. Also, consumerlab rated lycopene as a legitimate supplement, when in fact, the man who discovered it states that lycopene must be received by eating tomatoes---that if taken as a supplement, it destroyed in the stomach. The GREAT thing about the company is that when I called them for a refund, even AFTER the 30 day refund window had passed, they refunded me IN FULL, NO QUESTIONS ASKED. That is OUTSTANDING.
Hi Elliot. I just read the review you posted about ConsumerLab today. While I'm glad that we were able to help you easily get a refund, I hope that you appreciate that we work very hard to not only report reliable test information from our lab analyses, but to provide reliable clinical information. With regard to lycopene, for example, if you read our Review, we clearly indicate that the evidence for it "is indirect and far from definitive." Many people use lycopene, so we want to be sure they understand its limitations, as well as which products do or don't provide what they claim. We think that's better than not reporting at all on it. I hope that you will reconsider your rating of our site.
Sincerely,

I appreciate the evidence-based, scientific information CL provides in each review. It is a great reference and saves me hours of research on my own.
ConsumerLab.com does have a yearly subscription fee. I can't remember how much, but believe me, if you buy supplements, vitamins, protein, weight loss, and other natural/alternative/health products, ConsumerLab will save you money! We all know the claims made by companies, sounding almost miraculous, and often "too good to be true". Consumer Lab offers an unbiased, research-oriented study of different groups of supplements. A very recent report from Consumer Lab was on Apple Cider Vinegar. CL listed all the benefits of apple cider vinegar. Uses and indications for each set of products they review are given. They then showed a graph of different Apple Cider Vinegars they tested in their "Quality Certification Program", as quality testing is a main part of CL's information to consumers. On their graphs are products that are "Approved" or "Not Approved" after quality testing was done. CL explains why some products are not approved, and they supply the parameters of approved products. In addition (and the reason this site saves you money), CL lists the costs of the different companies and shows the "Best Buy". Consumer Lab is totally unbiased, and all their information is based on the research they have done. They look at such things as contaminants, such as lead levels, quality of products, cost, efficacy (such as does this product absorb into our systems). As a consumer of supplements, et. Al., CL is a valuable resource.
With the continuous scientific advancement of todays world we are confronted almost daily with vast amounts of new data. Evaluating significance and reliability together with implications for existing models or often the need to construct new frameworks is a full time job for the conscientious professional. For a concerned consumer Consumer Lab provides a unique and invaluable inventory of relevant analysis and interpretation. I cant imagine how an informed decision with respect to individual needs can be made without consulting Consumer Lab.
I have used this site for several years. The information is thorough and reliable. I've been surprised at some items that have failed. To me, it is essential in order to determine what brand to buy.
I had been considering subscribing for about a year but couldn't make up my mind whether or not to spend the money. I finally did subscribe a few months ago. I believe it is a sound investment.
I often read about how this or that supplement will perform some sort of miracle for you. ConsumerLab is an impartial source to get the truth about supplements so you can avoid wasting money. If you decide a supplement might be helpful, ConsumerLab will let you know which brands contain the ingredients they're supposed to.
In addition, they are good about responding to questions. For example, I had a question about whether collagen supplements contained tyramine. I wrote to ConsumerLab to ask about that, and Jared replied the next day with a clear answer.
I highly recommend subscribing.
Dave
Thank you, Dave. We're glad that you are enjoying CL!
Consumers expect free content, and yes, there IS plenty of good information on the web free of charge. But, in the world of nutritional supplements one must sort thru a mountain of misleading infomercials, anecdotal or superficial evidence, and bad science in order to find useful and credible information. Even if you have the necessary background in science or medicine to do so, who has the time?
ConsumerLab makes an enormous amount of good information readily available and should be required reading for anyone interested in taking supplements of any kind.

Answer: Hi Denise, We have actually covered this topic on our website https://www.consumerlab.com/answers/does-prevagen-really-improve-memory/prevagen-memory/.

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.
