I asked a question months ago as I have many allergies as well as celiac disease. Never had a response, though I was signed up for multiple daily emails that I did not sign up for.

Testimonial shoutout to the folks @FATTY15. A1C dropped from 6.0 down to 5.5 [Jan 16 thru 15 May]. No real changes except less wine drinking. This supplement is kinda pricey but it WORKS! Insert FATTY15 into your search browser. I’M SOLD!

This is in response to the review that Fatty 15 does not provide advanced notice of shipments: that is incorrect. Since inception of my initial order, I have consistently received advanced notification of impending shipments. It is quite easy to access the portal and delay or even cancel an order. In my own year of use, I’ve been able to adjust my orders easily. Of the three times I have emailed customer support, I’ve received an answer within 48hrs. As for benefits, I have seen improvement in my sleep, and my biomarkers: inflammatory markers, liver panel and cholesterol (my cholesterol has always been good—but it managed to improve even that!) Without context from the above reviewer, one would have no clue if their body is responding. Were they getting regular labwork? Etc? Further, 6 mos is about the timeframe when any system begins to see notable improvement. Even Fatty 15 provides a timetable for noticeable benefit. You cannot expect a product to work miracles within 6 mos. It took years to create the damage you expect a miracle with.
