I’m genuinely in disbelief by how great I feel! Guys, it’s been 2 days after receiving my 3 month supply and I can’t believe I’m about to say this but I feel so great—rested and energized (at the same time?), but it’s a very calm and steady energy. My anxiety and depression feel at bay somehow and I feel much, much more leveled out, not my usual self that feels burned out, crashes, and drags myself across the finish line by this point of the week. I’m genuinely in disbelief by how great I feel. I rarely reach out with reviews or reactions to products I consume but wow. Just wow. I actually feel happy tears coming on. Feels so great to hear back from you guys, you have something really special going on. read less

I want to thank you for your product. I literally canceled my upcoming order of fatty 15 yesterday. I got this notice that you were going to send my upcoming order on APRIL 23. I REALLY HAD NOT NOTICED ANY DIFFERENCE AND DECIDED TO GO AHEAD AND CANCEL MY ORDER. So, today was my yearly doctors checkup which included blood work. I had done nothing different like eating healthier, exercising, etc. EXCEPT for taking fatty 15. All of my bloodwork came back remarkably better with the exception of my cholesterol which was 220. My last cholesterol # was 228 so actually it was down 8 points. All I can say is all of this points directly to me taking fatty 15 for the last 3 months. I’m a 73 year old female and I am stunned at the other results. So, PLEASE REINSTATE MY FATTY 15 ON A EVERY 3 MONTHLY BASIS. I plan to take it from here on out. I want to thank you for all this inconvenience. But mostly, I want to thank you for your product. read less

Thank you! I am a chronic insomniac and I do have to take b6 to be able to sleep, but with fatty15 my sleep quality has discernibly improved, even before the end of the first month.

It improved my life I already have recommended Fatty15 to my friends. My wife is starting to use it. I’m trying to get my brother to start using it and one of my good friends in Charleston, SC. I was totally prepared to take it for three months and find it did nothing to improve my life. However, that was not the case. After 45 days, I felt more calm and had lost 10 lbs without much of an effort. I don’t know if everyone will have the same outcome but for me it improved my life in noticeable ways. read less
