What Shoppers Say About fatty15.com
Fatty15 customers are deeply divided on product effectiveness. More than half of reviewers (56%) give five stars and report noticeable benefits including improved sleep, increased energy, and reduced cravings, along with appreciation for the science-backed formulation and helpful customer service. However, a substantial portion of shoppers report no effects despite extended use, and some experienced gastrointestinal issues. A recurring complaint involves difficulty canceling subscriptions and unresponsive customer service when addressing order and billing problems, including unresolved refund requests.
The company receives praise for transparency, product quality, packaging, and individual customer service interactions. The main friction points center on inconsistent product results, subscription management processes that some find unnecessarily complicated, and occasional failures in addressing customer service complaints about shipping errors and account issues. Prospective buyers should be aware that personal results appear highly variable.

Sorted by: Most recentI've been really let down by this product. Not only did I not feel any positive effects, but I actually had some stomach problems. When I tried to cancel my membership and close everything out, it turned out to be way harder than it should be. They made the cancellation process so difficult! I had to send them an email to cancel. If that doesn't work, I'm going straight to the Better Business Bureau.
I'm really happy with this supplement and the customer service experience was excellent when I needed help. Fatty15 is here to stay in my routine!
I've been using Fatty 15 for about 9 months now, and honestly, I was really hoping to see some changes. The truth is I haven't noticed anything different in how I feel. The packaging looks nice and the customer service team is helpful, but unfortunately the product didn't deliver what I was expecting.
This supplement is fantastic! I notice real benefits every single day, like getting deeper sleep, having way more energy, and not craving snacks as much. Beyond what I feel in the moment, I love knowing it's supporting me at the cellular level as I get older. What really stands out is that everything is backed by real science, and they make it easy to learn about the research through their emails, resources, and the book by their co-founder. The team genuinely cares about the experience, and they'll actually connect you with someone who can dive deep into the science if you have detailed questions.
After we moved from our longtime home shortly after setting up the subscription, my first shipment came through fine. But the next two orders got sent back to the old address and nobody told me. I didn't catch my address error until I placed another order, and the same thing happened. When I asked for my money back or a credit, they wouldn't do it. They offered to resend one order but it never actually showed up. This was really disappointing and frustrating.
Fatty15 has won me over completely. The research behind this product is solid and they're transparent about it. The customer service people actually feel like real humans who care, not robots. One cool thing I discovered is that I can open the capsule and mix the powder into something else. It has basically no taste or smell, which makes it super easy to take.
This supplement is now a key part of everything I do for my health. My blood tests show dramatic improvements across the board. Getting healthier is what matters, and Fatty 15 definitely plays a major role alongside eating right and staying active. The company's customer service is outstanding, honestly better than what most places provide these days.
I've been taking Fatty 15 for several years and I'm really happy with it. The thing that got me interested was the science backing C15:0 and all the research supporting it. This isn't just some random supplement on the shelf, it's actually grounded in solid science and long-term studies. I've felt real improvements in my energy levels and how I feel overall. Plus, taking just one capsule each day makes it simple to stick with. Bonus: my hair has been growing really fast! Their customer service team is quick to help whenever I have questions. If you're looking for something to support your cells long-term and want to age well, I'd absolutely recommend this.
I bought a 30-day pack and when I went to order the 90-day refill, I started getting headaches and feeling constipated. I asked for a refund on that larger order since it was my first time trying the product, but the manager refused. They said they don't give refunds on refill orders, which seems pretty unfair to me.
