fatty15.com Reviews 

Fatty15 has been excellent! They have provided top notch customer service when managing my subscription and answering detailed in depth product questions. Their team is all very well versed in the science behind the product and the brand continues to keep us educated with the latest research and science behind C15:0 in their weekly emails. I've felt improvements in my health since starting fatty15 and recommend to all my friends now!

The customer service team is so nice here! If I didn’t already love the product, knowing that they have a smart, empathetic team that is reachable by phone and email is a game changer. When I called recently, I didn’t have to wait long to get assistance. Every other company you call and wait forever to talk to someone. Thanks fatty15!

I’m obsessed with health data, and checking my Whoop is the very first thing I do every morning. After about 9 weeks on fatty15—with zero other changes to my daily routine—my sleep consistently climbed over the 7-hour mark for the first time (historically I was closer to 6 hours). On top of that, my Whoop showed my pace of aging decreased by a full year. Fatty15 was the only variable I changed, and it completely lives up to the claims. Highly recommend!

I purchased fatty15 gummies recently and was very impressed with their customer service team. I had a lot of questions, and they took their time explaining everything to me in ways that were easy to understand! A lot of science went into their development and the customer service team was happy to educate me. It was a bonus that the gummies taste so good, and came in a cute resealable bag.

I recommend fatty15 now to all of my friends and family!

I started fatty about 6 months ago. I’m a customer for life. I feel so much better since I’ve been on this supplement.

I love this product, I've been taking it for 4 years and I would never be without it. The customer service team is one of the best I have ever interacted with, they respond very quickly and they are always more than happy to answer all my questions. I love fatty15!

I’m 75 and sometimes need help making changes to my subscription or updating my credit card, and the fatty15 team has always been so helpful. Everyone I’ve spoken with has been patient, kind, and made things really easy for me.

It’s so nice to be able to talk to someone who actually takes the time to help. I’ve had nothing but good experiences with the customer service team, and that means a lot to me. I’m very happy with fatty15 and really appreciate how well they take care of their customers.

I’ve been taking fatty15 for about 5 years and absolutely love it. It’s just part of my everyday routine at this point. Over the years I’ve also had a lot of interactions with the fatty15 customer experience team, and they have always been incredibly helpful whenever I’ve had a question or needed anything.

I’m a big fan of the product and the company behind it, and I recommend fatty15 to my friends and family all the time. After 5 years, I’m still happily taking it and plan to keep doing so!

I have been raking the fatty 15 gummies for about 3 months now. I had switched from my original capsule subscription (which their customer service made super easy!) The mint apple flavor is unique and a nice mid afternoon snack. I feel like it gives me the energy to get through the rest of the work day. The science updates I get are so interesting too. Cool company, cool products!

What sets fatty15 apart from almost any other supplement company is their commitment to education and scientific integrity. Instead of just throwing a product at you with vague marketing claims, they take the time to break down the actual cellular research and lipid science behind C15:0 in a way that is clear, accessible, and grounded. My phone interaction with their customer service team reflects that same high standard.

They are responsive, genuinely helpful, and clearly care about supporting their community. It’s rare to find a brand that blends cutting-edge scientific rigor with such thoughtful, human customer care.

Highly recommend to anyone who values what they put into their body and wants to understand why it works!

I started taking fatty15 a few years ago after reading about its potential to support healthy inflammation levels and honestly it has become one of those non-negotiables in my daily routine. My Oura ring data speaks for itself! My sleep scores have genuinely improved and I wake up feeling more rested. The energy and mood benefits have been noticeable too. Beyond the product itself, I appreciate how straightforward the whole experience is. Ordering is simple, the subscription is super easy to manage and the science education fatty15 puts out is genuinely impressive! They never ask you to just trust them, they point you to the published research every time. It feels like a brand that actually believes in what they are selling and that goes a long way with me. Highly recommend giving it a real shot!

I purchased the one month from the company and I found out that my doctor said that he did not advise me taking this product. Well I didn’t ask for the 30 days back, but I called and I canceled the subscription well the girl that I talked to evidently didn’t cancel the subscription so when the next one came, I called the day that it arrived and I told them that I had refused delivery on it evidently this company took the product back, but they refused to refund my money so I would not recommend this company to anyone because by the time you talk to the doctors to see if you can take it. They’ve already shipped you another one and it was their fault because I had called Customer Service to cancel. I didn’t think legally you could keep the product and still charge the customer but I guess this company can. To me since I refused it from the post office I didn’t just return it they should have refunded my money. Not acceptable company. Makes you wonder if their product is what it clams. They claimed they can’t help me because I turned it over to my bank, but the problem with that is they had already told me and I have the email to prove it that they won’t help me and that’s why I turned it over to my bank

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 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. 😢

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.

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.

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.

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. 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

Would not recommend!!!
No benefit & when you contact the company for a refund they state after 30 days no refund is available!!
