We monitor reviews for authenticity
I have been generally pleased with most of the reviews of products that I have considered using, although sometimes warnings are lacking for individuals with particular medical issues who should not be using these products because of food or drug interaction.
I would love to know if the supplements in vitamin patches really measure up to the volume they claim in each patch. Also, is there any research on the efficacy of their delivery system. I am primarily thinking about Patch MD. I have seen no mention of PatchMD in any of your reports. Other than that your newsletter is outstanding.
Thanks for your feedback, Carl. Please check out our CL Answer which included information on Patch MD. https://www.consumerlab.com/answers/do-vitamin-b12-patches-like-those-from-patchmd-really-work/B12-vitamin-patches/.

Thank you for that nice feedback, Suzanne!
Consumer Lab does a great job of testing and reviewing the various products that are offered. The only reason I gave them 4 instead of 5 stars, is that they often don't have the brands in their review, that I find in my local health food stores for some products. Yes, I realize there are a lot of brands out there.
We're glad to have you as a member, Stephen! Thanks for your review. You can always feel free, as can any member, to shoot us suggestions about products you would like to see tested.

Independent reviews is what I particularly like, it is my guide to purchasing supplements.
We're glad that you enjoy ConsumerLab.com. Thank you for posting your comments.
Being retired, I live on limited funds. I'm very grateful to check the purity and efficacy of supplements before I spend my coins. What is worse than a supplement not giving any benefit is Paying for that supplement then receiving no or detrimental effect. I am thrilled that I can rely on the independent reviews, analyses, and reports provided by ConsumerLab to utilize knowledgeable purchasing power.

Here is a list of our current reports: https://www.consumerlab.com/results/
