I only ordered 1 time
I only ordered 1 time. I went in & cancelled my subscription 2 weeks ago!! I received an email this morning that my order was being processed. Fatty 15 took $119.00 out of my bank account which is now in the Red bc of it. They r claiming they won’t refund my money even though order wasn’t shipped yet!! I told them I’m shipping this order back as soon as it arrives!! Fatty 15 is cheating people!! Don’t buy anything from them

Company should inform customers than C15 can also be found in dairy
Company should inform customers that although C15 is dairy free, C15 is a component of butter fat and can cause an unpleasant reaction to dairy intolerant people. Also sadly their return policy is only 30 days. $100+ down the drain. 😢

Hi Marie, Thank you for taking the time to share your feedback. We understand there may have been some confusion regarding fatty15's ingredients. As we shared with you directly, fatty15 is dairy-free and lactose-free. While the essential fatty acid C15:0 is naturally found in foods like dairy and butter, the sole ingredient in fatty15 is a pure, vegan-friendly form of C15:0 that does not contain dairy or lactose. If you have any additional questions, we're always happy to help at [email protected]. Best, Ali VP of Customer Experience

I have been reading some of reviews…
I have been reading some of reviews that have been posted by members that didn't seem to take the product longer than the one month trial. I will tell you that if I had just used the product for a month I would have given up too. The science was compelling so I stayed with it. At 6 months I saw new hair growth and better skin and sleep. Now. A year later, I have nit had an Epstein Barr flare or a migraine for several months. These two items were a monthly basis. Don't give up if you are dealing with inflammation as the swelling in my legs an feet....a thing of the past.

Be very careful giving out your credit card information
My relationship I contacted this company and requested to stop my subscription and not to charge my account anymore shipments. Well this afternoon they charge me another $125 after I asked them you just continue my shipments. I do not appreciate it and I would certainly warn anyone before giving them your credit card information.

One month review Fatty 15
I have been taking Fatty 15 for about a month. I can't be sure if it is the reason, but I have noticed a significant difference in leg inflammation and pain in my knees. Nothing dramatic but noteworthy. I bought as one time so not to get sucked into reoccurring shipments so will see what happens when I run out.

Incredibly Bad Customer Service - Customer is Always Wrong
I cancelled the subscription after taking about half of the original purchase, not feeling or noticing anything different, and that's when the fun began. After noticing a $100+ charge on my card I went to their web site and found my subscription was NOT cancelled. Their "friendly" customer service reps told me via email that it was really cancelled now, they had no record of me cancelling earlier, and to enjoy the product on its way to me since it could not be cancelled and COULD NOT BE RETURNED. I could refuse the unopened box product shipment if I wanted, but they would never refund my purchase. I notice here on Trust Pilot several others with the company's "friendly" customer service.

I wouldn't take this type of stuff
I wouldn't take this type of stuff. It's similar to a fish oil and a heart cardiologist. Let me know that all his open heart patients were ones that took fatty oils and vitamins like this and it clogs your arteries. They just wanna try and make money but stay away from these type of items
